Object effects

You can add extra visual effects to objects. For example, you could use the "Outline" effect to make an object to pick up or to use more visible. You can also use more advanced visual effects that change the shape of the object or create interesting visual results.

This game screenshot shows multiple objects with a Outline effect (giving the level a cartoon aesthetic), and the coins with a Glow effect.

Add an effect to an object

Double click on an instance of an object on the scene editor (or in the list of objects) to edit it. Choose the Effects tab.

Click Add a 2D/3D effect. A new effect called “Effect” is created. This name will be useful later for modifying the parameters of the effect during the game.

Choose the type of the effect. Click on the selector and choose one.

The window now shows the parameters for the effect - these parameters depends on the effect type that was chosen.

You can let the default parameters or change them now.

Try the game with the effect

Launch a preview to see the effect applied. The effect is applied on all the instances of the object you edited.

When a preview is running, you can see the changes you've made in real time by clicking on Apply changes to preview. Read more about Live Previews here.

Enable or disable an effect during the game

You can toggle an effect on or off without removing it entirely. Use the Enable an object effect action, specifying the object, the effect name, and whether to enable or disable it. The Object effect is enabled condition lets you check the current state of an effect.

This is useful for gameplay feedback — for example, enabling an outline effect when the player hovers over an item, then disabling it afterwards.

Change effect parameters during the game

Using events, you can manipulate the parameters during the game. It can be useful for different situations, for example animating or activating an effect only when an object is hit, firing bullets, moving, etc...

First, check out the name of the effect and the name of the parameter to change in the Effects tab. For this, activate the display of properties names:

In this example, the Dark Night effect is called "Effect" and has two parameters "intensity" and "opacity":

Select the object in an event, then use one of these actions depending on the type of parameter:

• Effect property (number) — for numeric values such as blur strength, brightness, or intensity.
• Effect property (string) — for text values such as the texture file path used by the Displacement effect.
• Effect property (boolean) — for yes/no toggles exposed by some effects.

For each action, enter the name of the effect (for example "Effect") and the name of the parameter (for example "intensity" or "opacity"), then provide the new value.

Danger

All of these names are case-sensitive. In particular, parameter names are lowercased. Be sure to double-check the name of your effect and parameters.
