Jump to: navigation, search

This page will teach you how to create an area in Pikifen. It will guide you through the creation of a simple area, teaching you the different mechanics and aspects of area creation. You can follow the entire document for the full guide, or read just the bold lines to get the general gist of how to do something. As you follow it, feel free to save your area after a section, quit the area editor, and check out how it looks in-game.

Note: The images on this page may be from several different versions of the engine. They can still be followed to understand the idea, however.

Introduction[edit]

Key concepts[edit]

A layout like this made up of two overlapping polygons (like on the left) is not possible. It must be made up of three neighboring polygons (like on the right).

Before you go on, you should know the following concepts:

To create the area's geometry, you draw the polygons that make out the floors.
Each "floor" (also known as "sector") of the area is made up of a polygon. Imagine you're in a square room. This would be represented with a square sector in the engine. In that room is a carpet; this would be defined by a different sector, with a different texture. Like real-world polygons, there are edges and vertexes. An edge makes up a line of the polygon, and a vertex is a point that joins two edges.
Polygons cannot overlap. They can only have neighbors.
If you want a triangle shape overlapping a rectangle shape, you need to know that the intersection between the three is an entirely separate sector. Check the diagram on the right.
A floor that is higher than its neighbor creates a wall.
In the room example, if there's a filing cabinet inside, it would be yet another floor, but it would be higher than the room's floor. The lines surrounding the cabinet's sector would be the walls of the cabinet.
Everything is top-down, and there are no ramps or slanted terrain.
You won't need to worry about what a wall looks like since you'll never see it, and you'll never need to worry about how a floor is angled.
To manage the layout, you add, delete, or move vertexes.
To change a sector's appearance or height, you change its properties instead, which can be edited in a specialized panel in the area editor.
You populate the area by placing objects.
Objects (or "mobs", short for "mobile object") are the Pikmin, leaders, plants, etc. in the area.

Using the area editor[edit]

The left-hand side is your workstation.
It shows you the sketch of the area, and it's where you can move and select the layout, objects, etc. The light-blue plus-shaped cross on the center is the origin, or the "center of the universe", so to speak. Its coordinates are 0,0, making it an important landmark when sketching.
The right-hand side contains panels for you to edit properties with.
When you select a sector, an object, etc., you can change its properties here, including a sector's height, the type of object, and more.
The bottom-left is the status bar. It can help you if you get stuck.
Normally, it shows your mouse cursor's coordinates in the world, but if you place the cursor on top of something in a panel, it will contain a description of that widget and what it does. It can also let you know if something went wrong.
In the workstation, a left mouse button click can select area elements.
Click on a sector, an object, etc. to select it.
A left mouse button drag can create a selection box, allowing you to select multiple elements at once.
Click somewhere empty and start dragging to create a selection box. Anything inside the box will be selected when you release.
A left mouse button drag can also move an element, or all selected elements together.
You can left click and drag on top of something to move it. If you move something that is selected, all of the selected elements will be moved together.
Use the right mouse button to pan, and the mouse wheel to zoom.
In the workstation, the right mouse button and mouse wheel control your view. Clicking and double-clicking the mouse wheel will also reset your zoom level and camera position, respectively.
Notes
  • As a general tip, save your area often, so you can go back in case you corrupt its geometry.

Guide[edit]

Creating a new area[edit]

For this guide, let's create a small forest-like area.

Open the area editor.
To do so, from the engine's main menu, choose the Area editor option.
On the panel, type in the name of the new area and press Return.
The panel will contain a list of existing areas for you to edit, but can also allow you to create your own. Type its name in the textbox, and press the plus button, or press your Return key, to create the new area. Let's call it forest. This is the internal name of the area, not the name that will appear on the loading screen.
Notes
  • A new area will already have a default sector with a grassy texture, as well as a leader object.

Setting the area's information[edit]

Before we start, lets give the area its proper name.

Enter the info panel.
From the main menu panel, click on the "Info" button to open the area information panel.
Change the area's name by changing the text in the "Name" textbox.
Let's call it "Simple Forest".

Moving vertexes[edit]

Moving the last edge to stretch out the sector.

The default sector works for a grassy plain, but is a bit small for our forest, so let's make it larger by dragging the vertexes outward. Vertexes are represented by blue dots. You can only edit the geometry in the "Layout" mode, so from the main menu panel, click the layout mode's button.

Click and drag a vertex to move it.
Left-click and drag the northwest vertex, and move it a bit north. The sector's shape will change accordingly. Do the same to the northeast vertex.
Click and drag an edge to move its vertexes.
Left-click and drag the bottom edge, and move it a bit to the south. Drag the left and right edges outward as well.
Notes
  • Don't drag a vertex such that it would turn a sector inside out.

Creating a new sector[edit]

Creating a new sector, one click away from finishing.

Let's create a rock in the middle of the area. This will be represented by a new sector.

Click on the "+" button at the top of the layout panel.
This will enter the sector creation mode.
Click on the area to place the first vertex.
Let's place the first vertex of our rock a bit to the east of the center of the area (which should be the origin, more or less).
Click in other spots to place the next vertexes in order.
Create the next vertex north of the center, then the second to the west of the center, then the third south.
Click the starting vertex to finish the sector.
Once you do, the new sector will have been created, with a rough diamond shape!
Notes
  • Your drawings should represent a sector entirely, so don't try to cut through other sectors.
  • You can also draw on top of existing vertexes and edges, and the sectors will become stitched together.

Adding and removing vertexes[edit]

The rock, after adding some vertexes.

Our rock doesn't look very natural, so let's fix that by making it smoother. For that, we'll need new vertexes.

Double-click on a line to create a vertex there.
Create a vertex in one of the existing edges so you can round up the shape better. Create some more and move them around as you please. Don't worry about the geometry looking too angular, because that's very common in games.
Drag a vertex into a neighbor to delete it and the edge.
If you've added too many vertexes, simply grab one of them, and drop it in the same spot as a neighboring vertex. The two will be merged together, and the edge that connected the two will be gone.

Sector texture[edit]

Changing the rock sector's texture to a stone pattern.

Because you've created the rock sector inside the grassy plain sector, it will have the same grassy texture. Let's change that.

Select the sector whose texture you want to change.
To select a sector, just click inside it. Once you do, the panel will show the sector's properties.
Click the texture button in the "Appearance" section of the panel.
This button will allow you to set the sector's texture.
Choose a texture from the suggestions list, or write its name on the textbox and press "Ok".
Most likely, only the grassy texture will be available on the list. The game's textures can be found in the Game_data/Graphics/Textures folder. When you type a texture's name, include the extension. You can type Stone.jpg, which is a texture that comes with the engine.
Notes
  • If the texture that shows up is a black-and-violet pattern, that means the engine couldn't load the texture. Make sure you wrote its name correctly (keeping in mind uppercase and lowercase letters), you included the extension in the file name, and the texture really exists in the Game_data/Graphics/Textures folder!

Sector height[edit]

To make the rock protrude from the ground, lets give it a height higher than the grassy floor. This will also make all of the rock's edges serve as walls.

Select the sector whose texture you want to change.
Like before, click inside a sector to select it. If you check the panel, the sector's height should be 0, the same as the floor.
Change the number inside the "Height" textbox. Higher number means higher height.
For our rock, set it to something like 200. It may be hard to visualize how it ended up in your head, but know that 200 is much taller than a leader, but not tall enough that most Pikmin can't be thrown on top of it.

Stitching sectors[edit]

The smaller rock connected to the main one.

Let's create a smaller rock that's connected to the existing rock. Create a new sector to the north of the central sector, set its texture, and set its height to 100, so the new rock is also shorter than the big rock. To close off the gap between the two rocks, you'll want to stitch the sectors together.

Grab one of the first sector's vertexes and drop it on the other sector's vertex or edge.
In this case, grab one of the small rock's southern vertexes and drop it on top of one of the big rock's northern vertexes. The two vertexes will merge together.
If the sectors around you turn red, it just means you can't leave the area as it is, and need to continue the stitch.
If you leave the area as it is right now, with only this vertex merged, the grassy plain sector will fail to triangulate properly because of engine limitations. But you aren't done stitching the two sectors yet, so don't worry about it and continue.
Grab the next neighbor of the first vertex you grabbed, and drop it on the second sector's vertex or edge, without leaving gaps.
In our case, grab the next southern vertex of the small rock and drop it on a nearby northern vertex of the rock sector.

Blending ground textures[edit]

Blending the two ground textures.

The ground looks a bit bland. Let's add a patch of dirt in the corner. Draw a triangular sector hugging the southwest corner of the area and set its texture to dirt (e.g. Dirt.jpg). But because the dirt and grass textures are so different, you'll see a clear split where one texture starts and the other begins. Let's smooth this out.

Create a thin and long sector between the two sectors whose textures you want to blend.
In our case, draw a sector adjacent to the triangle's northeast edge, with four edges in total.
In the "appearance" section of the sector panel, set it to a "texture fader" sector.
This will cause the sector to take a look at the sectors around it, and blend one texture into the other! The thicker your blending sector, the longer the transition.
If the blending is in the wrong direction, try making the blend sector longer and thinner.
The engine decides the direction to blend in based on the thickness of its edges. If you make the sector too chubby, it may think that you want to blend the other, longer edges's sectors.
If the blending becomes broken in certain places (example), split the blending sector into more sectors (example).
This is an engine and triangulation limitation. The blend may look a bit off in some angles, especially if your blend sector has a lot of curves. Just split it up and move it around until it works.

Out of bounds[edit]

The outer sector, as well as a fading sector to fade into the void.

In the Pikmin games, there is the area you play in, and some geometry outside that is too high to reach. If you don't include this outer section, your area will just be connected to the void, which looks bad. After you create this "out of bounds" sector, you can also add a blending sector between it and the void proper so its texture fades out into the void.

Draw a sector around the entire area.
Make it big enough that it is hard for the player to see where it ends from within the play area. Making it rectangular is usually a good choice, but you can make it in any shape.
Set its height to something tall, but reasonable.
Something like 500 units above the usual floor level is a good number, and will ensure most of your area gets a wall shadow cast onto it. While you're here, set its texture to something different, like Grass_light.jpg.
In the sector panel, go to the advanced behavior settings, and set the sector type to "Blocking".
This will ensure that nothing can go through this sector, even if the floor is within reach. This way, players won't accidentally throw Pikmin at the out-of-bounds area and exploit it, and Pikmin knocked by enemies won't be thrown too far to be reached.

Ramps[edit]

The ramp leading up to the big rock.

Let's create a ramp to reach the top of our big rock.

Ramps are basically just stairways. Create a series of sectors laid out like a stairway.
Draw one rectangular-like sector neighboring the rock, to its east, then another rectangular sector to the east of the previous one, neighboring it too, and then make a third one. Make them thick, but not too thick. Three steps should be enough for our 200-height rock.
Make each step of the stairway 50 units higher than the sector that comes before.
Objects can walk up 50-unit high steps without bumping into a wall. In our case, change the height of the easternmost step to 50, since the floor is 0. Then set the second to 100, and the third to 150. The rock is 200, so this will make a smooth walk up all the steps. Because these neighboring sectors are within stepping distance, the engine knows they're meant to serve as a ramp, so they won't cast shadows onto the previous step, making it all look like one seamless walkway.

Objects[edit]

The Onion and 10 Red Pikmin, near Olimar.

From the main menu panel, you can enter the "Objects" mode to place objects and edit their properties. The area we created already comes with a leader, but let's add an Onion and few Pikmin.

Move objects by clicking on them and dragging them.
Let's move our leader object (likely Olimar) to near the southern edge of the grassy plain, so the player doesn't start in the middle of the rocks.
Set an object's properties, like its angle, by selecting it and changing the widgets in the panel.
Let's make Olimar face north instead of east. Select him, and in the "angle" widget, angle it up, or set it to "-90".
Add new objects by clicking the "+" button on the top of the panel, then clicking the area.
When you press the button, you enter placement mode. You can now click on a spot in the area to place an object there. Click near the leader so we can place an Onion.
The new object will be of the last type you placed, or a Red Pikmin by default. Click on the "type" button to set its type.
In this list, navigate up to the "Onions" section and pick the Red Onion. After, place a Red Pikmin nearby. You may also want to make it face Olimar.
Select objects and press the "duplicate" button on the panel to place copies on the area.
To make your job of placing more Pikmin easier, select the one you placed, and press the duplicate button. Now click on the area to place the copied Pikmin there. You can now select these two, duplicate, and place them in yet another spot, and repeat as you want to get a big number of objects placed! Try placing down 10 Pikmin for this example.
Notes
  • Select an object and press the "delete" button on the panel to remove it.

Adding a gate[edit]

The closed room and the gate object.

Add a closed-off room on the northeastern corner. For this, create some tall wall sectors that will enclose the room. Leave an opening that's roughly 128 units wide. For extra aesthetic value, set the walls' texture to something stony (Stone.jpg), and select the room sector, go to its advanced appearance settings in the panel, and change its brightness to something like 128, so it looks darker and closed.

Create a sector for the gate to be in. This sector is what effectively blocks off access. Make it around 32 units thick, and 128 units wide.
Make this sector cover the opening you made, so that the room is either enclosed by wall sectors and this sector you made.
Set its sector type to "Blocking" using the advanced sector behavior settings.
This will stop objects from walking past the gate until it's opened.
Place a bramble gate object in the center of this new sector (use Shift to disable mouse cursor snapping).
The Pikmin attack the object proper, which protrudes past the blocking sector. So if the sector is too thick, the gate may not protrude enough. When it's destroyed, the sector returns to the "normal" type and grants access.
Rotate the object such that it matches the direction of the gate sector.
If the wall is covering north/south passage, and the gate object is facing east, that will be all wrong! Rotate it to match.

Adding a bridge[edit]

The bridge sectors and the object.

Now, let's make it so the Pikmin can build a bridge on the western side of the rock to grant access to the top. Basically, when the Pikmin finish working on a bridge object, a bunch of new sectors appear. You will have to define these sectors like normal, but give them special information so they act and look normal when the bridge is closed, and serve as a bridge once it's done.

Draw out the sector(s) that make up the built bridge. If it's a ramp, draw them out like a stairway like normal. Don't set any properties yet.
To reach the top of the rock from the ground level, we'll need to draw out three neighboring rectangular sectors.
Also draw out the sector(s) that make up the railing of the bridge. Once again, you can make a ramp, and you shouldn't set properties yet.
These sectors will be thin and long, and run parallel to the ramp sectors. They help make sure Pikmin and leaders don't fall off the sides of the bridge.
Set the sector's appearance to how they should look before the bridge is opened.
You likely don't need to change much, but keep the sectors with the floor-level height (0), and keep the grassy texture.
In the advanced sector behavior settings, set the "Bridge height" field of each bridge sector (both floor and railings) to the height the sector should be after the bridge is opened.
When the bridge opens, all bridge and railing sectors will have their texture changed to a bridge texture, and will also have their height updated to whatever the "tag" field says. Naturally, the railing sectors should go higher than the bridge floor. Like the ramp from before, set the "Bridge height" of the ramp closest to the bridge to 50, the one after to 100, etc., and keep all rails around 120 units higher than the bridge floor sector they are meant to be railing.
Set the bridge floor sector's types (in the advanced sector behavior settings) to "Bridge", and set the railing sectors to "Bridge rail".
The sector types are how the engine knows what sectors to change for the bridge's construction. The two different types will also influence the texture that appears.
Place a bridge object inside the first sector of the bridge.
In our case, this is the bottommost (the westernmost) sector. Since the bridge opens to the east, keep the object's angle facing east.

Adding water[edit]

The pond of water, with a texture fader around it.

Let's place a small pond on the northwest corner.

Create the water's sector.
Any object standing on this sector will be considered submerged underwater. Make a nice oval shape for it, and add texture blending if you want.
In the advanced sector behavior settings panel, press the "+" button in the hazards section, and choose water.
All liquids are tied to a hazard. This means a sector can have muddy water, acid, lava, and so on, but there has to be a hazard controlling it. You can learn more here.

Carrying paths[edit]

Some carrying paths all laid out.

If you try to go inside the enclosed room with some Pikmin, and lie down to have them carry you, they will most likely get stuck on the walls of the room. This is because they don't know what path to take. So let's define the general path Pikmin can take around the area, and what way they should go to avoid obstacles. First of all, from the main menu panel, enter the "Paths" mode.

Press on the "+" button on the panel to enter the path drawing mode.
In this mode, you can draw the path on the area by clicking.
Click somewhere the place down a path stop.
Path stops are a bit like bus stops. The carrier Pikmin go in a straight line from the previous stop to the next, then turn to face the next stop, and so on. The first stop you want to create should be very close to the Onion, or at least on the starting area.
Click somewhere else to place a new stop, and connect the previous to the current one.
This will create the second stop and will also link the two. Now the Pikmin know that from the first stop, they can go to this second stop. You should place the second stop to the south of the rock sector at the center. Keep clicking around to make a path that goes around the rock and ramps (remember that if the bridge is built, it will be a solid obstacle too!)
Normal links (recommended) allow Pikmin to go from A to B, and B to A. One-way links only allow from A to B. Change link types in the panel.
Add a one-way link that goes from the top of the rock to the path stop to the south of the rock. It would make no sense to leave this one as a normal link since Pikmin could try to follow that path and bang against the rock's wall.
Notes
  • Keep in mind Pikmin will be carrying large objects through these paths, so make sure there's enough space around them.
  • Pikmin go to the nearest stop when they begin carrying. Make sure that for most places, the nearest stop is not on the other side of a wall or through a hazard.
  • Don't worry about making your paths 100% foolproof, since not even the canon developers could do it.

Tree shadows[edit]

The standard tree shadow on top of the area.

One important detail to add to most outdoor areas is the shadows the trees and leafs cast onto the floor. Because they sway left and right, and also change opacity in real-time, they cannot be baked into the textures of the area, and instead need to be their own thing. You can only edit tree shadows in the "Details" mode, accessible by pressing the mode's button from the main menu panel.

Press the "+" button on the panel to place a new tree shadow where you click.
Click more or less in the center of the area, since this will also be the center of our tree shadow.
Set its texture in the "File" textbox.
This texture should be in the Game_data/Graphics/Textures folder. Remember to include the extension. Until you give a valid texture, it will just be a black-and-violet pattern. Try using Tree_shadow.png, which should come with the engine.
Use the handles around the tree shadow to move it (center handle), rotate it (large circle around it), or scale it (8 handles on the edges and corners).
Use these to make the shadows cover the terrain, the outer rim, and even a bit of the void, just so the player cannot see when the shadow texture ends, even as it sways left and right. To scale the width and height independently, uncheck the "Keep aspect ratio" option.
Notes
  • Don't worry if the texture is so stretched that it becomes blurry. That's actually a good thing, since shadows of distant things are blurry.
  • You can make the shadows sway more or less with the sway multipliers, and you can make the texture less opaque in general with the opacity slider.

Reviewing[edit]

The sector-based system works well for areas in the engine, but has a few drawbacks. If you mess with the sectors, edges, or vertexes in ways that aren't expected, the sectors will have problems and will not work properly in-game. Even if everything works okay, it may not look exactly like you envisioned in the editor. You can use the review mode, accessible by the "Review" button on the main menu panel, to make sure everything is all right with your area, and that it matches up what what you want.

Use the "Find errors" button to search for problems with the area, from logical mistakes to parts of the geometry being corrupted.
If the area editor finds a problem, it will tell you what it is, and will explain a possible way to fix it. Some problems also unlock the "Go to error" button, which will move and zoom the camera to focus on the problem. This process is important to follow often, because if you ended up corrupting something, you will want to fix it sooner rather than later.
You can use the "See textures" button to visualize how the area will look like.
This will show the textures painted out fully and walls casting shadows. You can also enable the "See tree shadows" option to show the tree shadows, if any. This allows you to get a nice feel of the overall aesthetic of your area.

Other basic operations[edit]

Deleting a sector: You can delete a sector by merging the sector's edges, one vertex at a time, until it has no more edges left. If this sector is isolated, meaning that it's not connected to any other sector, you can just select it and click the sector deletion button on the panel. But if it is connected, you'll have to delete edge by edge.

Unstitching a sector: To separate two previously-stitched sectors, create a vertex on either one of the sectors, next to the vertex where the connection begins. Then create another vertex in the middle of that and start dragging it through the stitch, connecting it to the next vertex of the stitch. This made an opening. Continue with this process of moving the opening along the stitch and you should soon separate them. Imagine this as having a ball of plasticine and squeezing one end with a finger until it eventually splits.

Making a bottomless pit: Just set the sector type to "bottomless pit". The engine will treat this sector like it would the void that surrounds the area, meaning objects can't go through it, and it is possible to see through it.

Making a circular sector: You can't draw actual circles, since those don't have lines, but you can get close by drawing a polygon with a lot of same-length lines. Instead of painstakingly drawing out the lines, you can click the button next to the new sector creation button to start the process of drawing a circular sector. Start by specifying the center of the circle, then its radius, and finally, how smooth it is.

Advanced[edit]

Area background[edit]

If instead of a black void, you want the area to have a background, like the steel plates at the background of sublevel 1 of the Secret Testing Range, or if you just want the background to be a color that isn't black, you can.

In the area information panel, you can set the background's information here. The background's texture must exist in the Game_data/Images/Textures folder. Remember to include the extension. This texture will be tiled across the background, and you can change how far away the texture is (which affects the scrolling when you move the camera around), as well as how zoomed in it is. You will not be able to see the background in the area editor.

Subtitle and weather[edit]

If you want your area to have a simple subtitle to show up on the loading screen, like the "Battle enemies!" subtext in Mission Mode, you can specify it in the "subtitle" option in the area information panel. In addition, you can also specify the weather condition to use in this area (if any), which affects the lighting throughout the day, and can have some visual effects and particles. See this page for a guide on how to create weather conditions.

Advanced texture settings[edit]

Suppose you have a texture for a circular tree trunk and you want to put it on a sector. But the way the texture is aligned, it doesn't match up with the sector at all. It is possible to rotate, scale, and move a sector's texture such that it fits your needs. Enter the advanced sector appearance settings panel. You can adjust the numbers in the panel to transform the texture. This process is very hard to do manually though, so you can instead go to the tools panel, accessible from the main menu panel, and enter the texture transformer. Change what operation you want to perform using the panel, and then drag a sector's texture around to transform it. These transformations are based on the origin (coordinates 0,0), so for instance, the texture rotates around the area's origin.

In the advanced sector appearance settings, you can also tint the texture with any given color. This is a great way to darken the texture without actually tampering with the sector's brightness.

Persistent shadow casting[edit]

If you want to make it so that a sector will always cast a shadow against its neighboring sectors, regardless of how much higher it is, there is a checkbox for that on the advanced sector appearance's panel. This is useful for when you have a tiny step up in the terrain (which doesn't normally cast a shadow), but it looks ugly against the other terrain, so you want it to cast a shadow. For example, a tree's root protruding slightly through the ground.

Script variables[edit]

When you place an object, you can specify some special properties, that are unique to each object type. This is done by writing the variables and their values in the "Script variables" textbox in the object's panel. Each variable follows the format variable=value, and you separate them with semicolons (;). Example: maturity = 1; sprout = true.

That example contained variables that a Pikmin can use. Specifically, that would make it start as a leaf (0 would be a leaf, and 2 a flower), as well as start as a sprout buried in the ground.

With this, you can also spawn functional info spots. They are on the "Special" category, and they serve as objects that give the player information when a leader walks near. The text variable controls what text shows up. If you want to make it so the spot only shows information if the player presses the throw button, set the opens_box variable to true. Finally, on the text to display, you can use \n to add a new line.

Sideways view[edit]

At times, it may be very hard to visualize in your head just how high a sector is in comparison to the sectors around it. You can get a graph that shows what a slice of the area looks like from the side, which should help you get a better understanding of your world. When reviewing the area, there is an option to enable the cross-section view, which, as the name implies, draws a cross-section of the area. The length and angle of this cross-section is determined by points A and B, that show up on the area when you enable the option.

Move the points to make them cross some edges, and see the window at the top-left update accordingly. To get an idea of what you're seeing, imagine that, from the game world, you cut an ultra-thin block, represented by the line, and are looking at it from the side. The location of A is at the left of the chart, whereas B is on the right. If you move your mouse near the line, you'll see a gray line on the window that represents where the cursor is. You can use this to get an idea of where each sector is. The chart will also have a Pikmin icon, which represents the standard Pikmin height, just to give you extra perspective.

Reference[edit]

If you made a reference image for your area, like a sketch, you can place it on top of the editor, so that you may draw through it. The information for the reference will be saved in your user data folder, and will not show up in-game, only on the editor. To use one in you area, go to /User_data/Area_editor_references/<your area folder's name>; create any folders that don't exist. Then, place your image in this folder, and call it Reference.png.

You can now go to the area editor. If you already had the area open, reload it for the reference image to be recognized. From the main panel, click "Tools", and now you can either edit the position and size of the reference using the textboxes, or you can use the handles; they should work just like transforming a tree shadow.

You might notice that the reference isn't visible when you're out of the "Tools" mode. It's not gone, it's just invisible. Remember that the reference's visibility can be toggled with the "Toggle reference" button on the bottom-right corner's toolbar.

Precautions[edit]

  • Don't drag vertexes such that you would turn a sector inside out, nor that two lines would intersect.
  • When stitching several vertexes, go one neighbor at a time. If you leave a gap, the engine might report an error on the gap sector until it is properly closed.
  • Don't split a sector into two by inserting a different sector in-between. If a sector is split into two, it stops being one polygon and becomes two. The engine isn't ready to handle that, so fill in one of the two polygons with an entirely new sector.
  • Sectors must be simple. The only noteworthy part about this fact is that when making a sector, you can't have its edges share the same vertex more than twice.
  • Areas are very complex on the engine, and crashes can happen. Save often, and if you happen to experience a crash and lose your work, open the area again, go to the options menu on the area editor, and load the automatically-saved backup from there.
  • Sector creation is equally complex. So long as you don't try to cut corners or do anything too fancy when creating a sector, it should all go fine.

The "Find errors" feature might detect some of the more common problems you may get yourself into, but don't rely on it always.

Troubleshooting[edit]

  • If the area editor crashes or something breaks the area, remember that backups are automatically created. Before the game overwrites the backup with something you don't want, consider going into the area editor's options, and loading from the backup.
  • If you have a sector at the corner of a sector that is meant to cast a shadow, it won't cast one. You can either remove that sector at the corner, or turn the vertex corner into a new edge just for the sake of the sector that isn't getting shade.

Tips[edit]

  • You can move entire sectors by clicking on them and dragging them.
  • You can drag multiple vertexes, edges, sectors, objects, or path stops together by selecting them and dragging one.
  • You can force the engine to only select vertexes, vertexes and edges, or everything, by setting the selection filter. Click on the filter button at the top of the "Layout" panel to toggle the current filter.
  • If you accidentally clicked the "+" button to create a new sector, object, etc., you can press it again to cancel.
  • Holding shift will free the mouse, so that you're no longer forced to do things exactly on the grid.
  • When creating a new vertex via double-click, you don't need to let go off the mouse button on the second click; you can move the vertex right away if you keep it held.
  • When drawing out a new sector, if you accidentally placed the last vertex in the wrong spot, you can click that same vertex to try again.
  • Although most of the work is done on the editor, you are free to edit the text file manually if you need to fine-tune some numbers.
  • A "texture fader" sector will also fade between levels of brightness and texture tints. Use this creatively.
  • If you place your mouse cursor over elements in the panel on the right, you'll get a description about them. With this, you can also learn about shortcut keys. For instance, holding Ctrl and pressing D will allow you to quickly duplicate the currently selected object.
  • With the stock content that comes with the engine, Pikmin or leaders thrown by the player's leader can reach a maximum height of:
    • Leaders: 133
    • Purple Pikmin: 219
    • Standard Pikmin: 271
    • Yellow Pikmin: 328
