This page details all the interface elements and actions in the Overgrowth level editor.
The level editor lets you create new levels or even whole campaigns. This is the same editor we used to make the Overgrowth and Lugaru stories.
You can use the level editor to edit any existing level in the game.

Activating the editor
To activate the editor:
- Create a new level (File -> New)
- Open an existing level and press F1
If the editor is active while playing a level, you can open up the editor window again by pressing the Esc key.
You can deactivate the editor by hitting F1 a second time.
If you can't get the editor to activate, there are a few things you can try:
- If you have a laptop, try holding the fn key while pressing F1
- Mash all the modifier keys a few times to make sure they're not stuck down - ctrl, alt, shift, command, etc
- Make sure you have all other programs closed, in case one of them is conflicting with the F1 hotkey
- If some "Help" program comes up when you hit F1 (such as "HP Help"), edit its settings to disable the hotkey.
Or just uninstall it (because it is bloatware)
|W||Moves camera forward|

Here are the different ways you can select objects.
|Select single object||double-left-click on object||Selects clicked on object and deselects all other objects. If the object is part of a group, the whole group is selected. A box around the object indicates that it is selected.|
|Toggle-select objects||shift + double-left-click on objects||Toggles selection of clicked on object. Preserves existing selections.|
|Box select objects||left-click + right-click + drag, or left-click + 'b' + drag||Selects all objects whose centers lie within box drawn on screen. Deselects all other objects.|
|Box add to selection||shift + left-click + right-click + drag, or shift + left-click + 'b' + drag||Adds all objects whose centers lie within the drawn box to the selection. Preserves existing selection.|
|Select decal or object that is under another decal||mouse wheel up/down||When you have 2 or more objects or decals on top of each other, you can select at least 1 decal or object, put your mouse cursor on top of the one you want to select, then use the scroll wheel to switch your selection between the objects.|
|Select all||cmd-a||Selects all objects.|
|Deselect all||double-left-click away from all objects||Deselects all objects.|
Note: If the Debug window is open (Top Bar -> Windows -> Debug Window), then when you select an object some useful information will appear. It shows you what xml file the object is created from, its unique object id, and what type of object it is.
For all transformations:
- In order to transform an object you must first select it.
- Hold ctrl to make movements snap to half-meter increments.
- Hold alt to clone and transform the selected objects, leaving the original objects behind.
- Left-click transforms objects on all axis. Right-click transforms on the two axis that are perpendicular to the side of the bounding box you click on. Holding shift and right click locks the transformation to the axis parallel to the bounding box face you click on.
- Groups are transformed around the group center. Ungrouped objects, even if multiple are selected and transformed at once, are transformed around their own individual centers.
Hover mouse over central region of a bounding box' face, or hold 't'.
|Camera relative||left-click + drag||Translates clicked on object along plane parallel to the screen.|
|Locked to plane||right-click + drag||Translates clicked on object along plane of clicked on face.|
|Locked to line||shift + right-click + drag||Translates clicked on object along normal of clicked on face.|
|force decal(s) to map only one object/group||hold i||selected decal will only map with that object that is directly underneath your mouse|
|force decal(s) to project only on selected objects||press o||selected decal will only map with that object that is directly underneath your mouse|
|projection box/angle||press p||to make projection box for decal|
Hover mouse near bounding box corners, or hold 'e'.
|All dimensions||left-click + drag||Scales clicked on object in all dimensions (x, y, and z) at once.|
|Locked to plane||right-click + drag||Extends clicked on object along plane of clicked on face.|
|Locked to line||shift + right-click + drag||Extrudes clicked on object along normal of clicked on face.|
Just use the right-click scale tool, and scale down the object until it flips and its mirror image begins scaling up!
Hover mouse near bounding box edges but away from the corners, or hold 'r'.
|Free||left-click + drag||Rotates clicked on object as if you are pushing the surface of a ball.|
|Locked to axis||right-click + drag||Rotates clicked on object about normal of clicked on face.|

Just below the top bar menu, on the left side, is a space for debug information.
This window is only visible if you have the Debug Window enabled (Top Bar -> Windows -> Debug Window).
It will tell you information about the selected object, checkpoint progress (if checkpoints are enabled in this level), and a warning if the nav mesh needs to be updated.
The bar across the top of the window is the editor menu. Many editor functions can be found here, but some functions can only be reached via hotkeys for now.
'Cmd' refers to the '⌘' key on Macs, and the 'ctrl' key on PCs.

Functions Without Buttons
Some functions are only reachable via hotkeys, here are a list of those.
|Make player-controlled||Shift+Cmd+P||Toggles whether a character is controlled by a human or by AI. A human-controlled character's spawn box has a green outline, an AI-controlled character's box has white outlines. If two characters are set to be human-controlled Overgrowth will start in split-screen mode the next time game-play is resumed from editor mode. The second player will be controllable via a USB controller.|
|Spawn Dead||Cmd+K or Ctrl+K (with character spawn selected)||Makes selected characters spawn dead. It will spawn at the point it went into ragdoll mode (which may cause it to spawn "dead" while standing up). If you want to update the pose for the dead body then move the body, select the spawn point, and hit the hotkey again to save its new position.|
|Spawn Alive||K (with character spawn selected)||Makes selected characters spawn alive.|
Every object as well as the level itself has several parameters. The most basic ones that all objects have are Name, Translation, Scale and Rotation. Other parameters you might find on an object are color tints and Script Parameters.
There are several ways to edit these parameters for an object. The fastest and easiest way to do it for a single object is by using the Single Selected window (press I to open it), which shows all of the parameters for the most recently selected object.
If you want to view or edit the parameters of several specific objects you can use the Selected Window.
To view and edit parameters for all the objects in the level, as well as the parameters for the level itself, use the Scenegraph Window.
The Selected Window (or parameter editor) lets you change different parameters depending on which objects you have selected.
You can bring up the parameter editor for an object (or set of objects) by selecting them and pressing the U key, or clicking Top Bar -> Windows -> Selected.
Here is a description of what each parameter does:
|Name||Give an object a custom name, so you can find it in the scenegraph window (see below), or let a custom script find those objects so they can do special things to them.|
|Transform||Adjust the position, rotation, and scale of the objects manually. There is also a button to reset the rotation (which is useful when creating object prefabs).|
|Color Palette||Tint objects, or make them super bright. If the character provides a mutli-part color palette, set different colors on different parts.|
|Script Params||Custom parameters used by scripts. Each different object type can define their own script params. See Script Parameters page for descriptions of all parameters.|
The Scenegraph Window (or parameter editor) lets you change global level parameters, as well as find objects in the level.
Open up the Scenegraph for the current level by pressing the Y key, or clicking Top Bar -> Windows -> Scenegraph. Let's go through each part of the Scenegraph window from top to bottom.
If you expand the Level entry at the very top of the window you will find some parameters that can be changed:
|Loading Screen Image||A path to an image that's shown while loading the level|
|Sun Position||The position of the sun in the sky|
|Sun Color||Tints the color of the sun, useful for sunrises and sunsets|
|Sun Intensity||Controls how dark the shadows are|
For a description of the level script parameters, see the Script Parameters page.
Below the Level entry at the very top there is a search field. Write in this field to search for objects in the level. This searches in many of the objects' fields. You can for instance search for something written in the Name parameter of an object, object IDs, object paths, types and more.
The Flat checkbox controls how the Scenegraph list is displayed.
If it's not checked you can expand groups to see the relations between objects in the graph.
If it's checked you can no longer see group relationships, but you can instead expand each individual object to change any parameters associated with it.
If this is checked the Scenegraph list with only display objects that have been named. You can name an object by selecting it, bringing up the Single Selected window by pressing I, and then writing something in the Name field.
The Color Picker is used to tint the color of selected objects.
It is opened by pressing cmd+p, or Top Bar -> Windows -> ColorPicker.
The color picker consists of a color-gradient box, a rainbow slider, the RGB values, and an overbrightness slider. Increasing overbrightness makes the color brighter, and makes it glow in the dark.
For characters, the color picker will let you set the color of different parts of the character. This is only available if the character was built to support a multi-color palette (not all of them do).
To edit the sun, find it in the sky and double-click it. Now you can click and drag on the circle to change the intensity of the sun, click and drag on the dot to change the color and click and drag on the sun itself to move it around the sky.
If you can't see the sun, its intensity might be too low (yes, the higher the intensity the less visible the sun is). To decrease its intensity via a numeric value to make it show up, or change any other of its settings via numeric values, use the Scenegraph window.
The Dialogue Editor is used to create scenes with different camera angles, text and poses. It is commonly used to give context and progress the story in a level.
This is a big enough subject to warrant its own article, which can be found here.
Sometimes you want to have a dead character in your level. The obvious solution would be to export a new model of a dead character and place it in the level. However, that's a lot of work, and the character wouldn't be dynamic, and it would take a lot of work to make changes to it.
Luckily there is a system in the engine for making any character spawn as a corpse. Here are instructions for how to use that system:
- Spawn the character you want to spawn as a corpse.
- Select its spawn box and press cmd+K to make it spawn as a corpse, which will kill it. At this point the corpse will spawn standing up when you restart the level with L, we'll fix that in the following steps.
- Enter play mode by pressing 8, go close to the corpse and hold right click to drag it around until you're satisfied with the pose.
- Now exit play mode by pressing escape, select the character's spawn box and press cmd+K again to update the pose of the corpse.
- Press L to restart the level and verify that it worked.
If you want to make a corpse to spawn alive again, select its spawn point and press K.
