The editor user interface

This page details all the interface elements and actions in the Overgrowth level editor.

It can be accessed by creating a new level (File -> New), or by pressing the F1 button while in an existing level.

If the editor is active while playing a level, you can open up the editor window again by hitting Escape.

You can deactivate the editor by hitting F1 a second time.

Note that while the editor is active, no story mode progress will be saved, and no story levels can be unlocked.

Camera Movement

Control Behavior
W Moves camera forward
S Moves camera backward
A Moves camera left
D Moves camera right
Shift + W Moves camera up
Shift + S Moves camera down
Left click and drag Rotates the camera

Object Selection

Here are the different ways you can select objects.

Action Control Behavior
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.
Debug window

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'.

Action Control Behavior
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'.

Action Control Behavior
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'.

Action Control Behavior
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.

Debug Window

Functions Without Buttons

Some functions are only reachable via hotkeys, here are a list of those.

Action Control Behavior
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.

Selected Window (object parameters editor)

Selected Window (object parameters)

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:

Parameter Description
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.

Scenegraph Window (level parameters editor)

Scenegraph Window (level 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:

Parameter Description
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.

Search field

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.

Named Only

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.

Color Picker

A crete block with its color altered by the color picker.

TODO: Need to add info or a link to a description of special object parameters that are controlled by color, like Water Froth movement, etc

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).

Save Selected Objects

TODO: This is referred to as "object templates" above, in the Edit menu's description (but not in the name of the command). The hotkeys may not be accurate anymore. A description should be added that describes how it works, and how it is different from a prefab (because it doesn't auto-update. It might also not support connections?)

Once you have created something you wish to use elsewhere, press Ctrl+Shift+S (On Windows) or Command+Shift+S (on Mac) to open an object saving dialog. This way, you can save buildings, trees or obstacle courses made from many parts as a single XML object, ready to be imported back to Overgrowth.

Sun Editor

TODO: Need screenshots of the main sun editor, and need to describe how it can also be edited in the scenegraph/"level parameters"

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.

Dialogue Editor

TODO: Need to verify this is all accurate, up to date, and complete. It probably needs its own article, with screenshots. Also needs to carefully describe what lines you need to have selected in the editor for it to work properly (animations, object and camera positioning, etc, are very sensitive to which line is selected)

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.

Getting Started

Write the dialogue

Create a text file in your mods Dialogues folder (../Overgrowth/Data/Dialogues) and write the dialogue in it like this.

#name "Mirage"
#participants 1
say 1 "Thorn" "You there!"
say 1 "Thorn" "Do you have any..[wait 0.4] water?"
  • The #name "Mirage" is the name of the scene. This is given to a dialogue hotspot on so it knows which dialogue to activate.
  • The #participants 1 is how many characters there are in the scene. The numbered boxes above the dialogue object are connected to spawn points to decide which character is which in this scene.
  • say at the beginning of a line is used to make someone say something.
  • The 1 is the ID of the participant that should say the dialogue, this decides who moves their mouth when the dialogue appears.
  • "Thorn" is which name should appear for the dialogue
  • The text within the quotes at the end of the line is the dialogue itself.
  • The [wait 0.4] will make the dialogue text pause for 0.4 seconds before continuing to display the next text.

Save and close the file.

Set up the scene

Open up your level in the game, go to the Dialogue tab in the ribbon and click Load Dialogue. Select the dialogue file you created and click in your level to spawn it there.

There is a small box above the dialogue object that you just created. Select this object and alt-click on a character to tell the game that the participant with ID 1 is that character.

Select the box and press Edit Selected, bringing up the text of the dialogue on the screen. Use the arrow up and down keys to select what line in the scene you want to edit. Now press Toggle Recording, which creates a few more useful objects in our scene:

  • Camera (with accompanying preview window)
  • Torso control
  • Head control
  • Eye control

Move the camera to choose where the camera will be when the dialogue reaches the selected line, scale it to zoom in or out. Move the torso, head and eye controls to choose where the character's torso, head and eye should be pointing at that point. You need to scale up the torso and head controls for them to have any effect.

Press Load Pose and find the files with names that start with r_dialogue, find one that you think might fit and load it to make the character take that pose when the scene loads.

Press Preview Dialogue to test the scene. When you're happy, click Toggle Recording again to turn it off and press Save Dialogue to save your changes to the scene.

Trigger the scene

Now we have the scene set up, but we don't have anything that triggers it yet. We can use a dialogue hotspot to make that happen. So go to the Home tab and press Load Item, go to the Hotspots tab, click the Start Dialogue hotspot and click on the ground in your level. This should spawn a wireframe cube with a green sign icon in.

The dialogue will trigger when the player enters this hotspot, so place it where it will trigger when you want it to. Just make sure the player spawn is not inside of the hotspot, as that won't work when the level is restarted.

Press U with the hotspot selected and change the Dialogue property to be the same as the #name setting in the dialogue you want to trigger. If you've followed this example, that would be Mirage. If you don't want the dialogue to automatically trigger when you enter the hotspot, uncheck the "Automatic" checkbox.

Now save your level, start playing, enter the hotspot, and the dialogue should trigger!

Spawn Corpse

TODO: Verify this is all accurate, add screenshots, add note that if you try to save a corpse while the character is alive that it will be a "corpse" standing up, looking possibly alive until you attack it

To make a character spawn as a corpse, select it and press ctrl/cmd + K to turn on corpse mode. The character will now be a corpse when it spawns. If you want to place the corpse in a specific location or position, you can drag the corpse to where and how you want it, then hit ctrl/cmd + K with the spawn box selected a second time to save its resting position as its new corpse spawn location/position.

If you want to make a character spawn normally instead of as a corpse, select its spawn point, and press K.
