Prefabs

Prefabs are a useful feature to allow reusing actors and triggers across multiple scenes. Imagine them as templates.

Creating a Prefab

You can just click the button, select Actor or Trigger depending on the game needs.

This will generate an empty prefab.

From Actor to Prefab

If there is an actor inside a scene that is not linked to a prefab, it can always be turned into a prefab later on.

To do that, just go to the Editor Sidebar and select Convert to Prefab.

From Prefab to Actor

If there is a prefab on a scene and that prefab, for some reason, needs a lot of custom changes you can always unpack it from the prefab.

To do that, just go to the Editor Sidebar, go to the blue prefab area, and select Unpack Prefab.

Instancing a Prefab

To use a prefab inside a scene, just go to the Navigator and then click the button of the desired prefab.

Then, the instanced Actor or Trigger can be placed on the scene.

Updating a Prefab

There are some instances when a prefab may vary slightly, like a different number on a starter value.

The values on the instanced prefab can be adjusted once it's instanced on a scene. The edited values will be displayed with an outer blue glow.

warning

Only values or references can be different, the events will always be shared.

Apply Changes

If you later want to apply your changes to the prefab, you can go to the Editor Sidebar, go to the blue prefab area, and select Apply Changes.

This will make the custom value the default one for this prefab and the outer blue glow will disappear.

Stamps

Stamps are group templates that contain multiple actors and triggers arranged in a specific layout. Unlike individual prefabs, stamps capture the spatial arrangement and relationships between entities, letting you place pre-configured groups into any scene.

Creating a Stamp from Selection

1. Select one or more actors and/or triggers in a scene (using multi-select).
2. Right-click and choose Create Stamp From Selection.

The stamp captures each entity's relative position, sprite, scripts, and all settings.

Creating an Empty Stamp

In the Navigator sidebar under Prefabs, click the dropdown and select Stamp. You can then configure the stamp manually in the Stamp Editor.

Placing a Stamp

1. In the Navigator, find your stamp under the Prefabs section.
2. Right-click and select Place Stamp.
3. Click on a scene in the world view to place all the stamp's entities.

All actors and triggers are created at their relative positions from the click point. Actor references within scripts (e.g., "Move Actor" events referencing another actor in the group) are automatically remapped to point to the newly created copies.

Editing a Stamp

Click a stamp in the Navigator to open the Stamp Editor in the sidebar. Here you can:

• Rename the stamp.
• Add or edit optional notes.
• View and modify the list of contained actors (with positions).
• View and modify the list of contained triggers (with positions).
• Delete the stamp via the dropdown menu.
