#### :warning: Important :warning: Set up the physics layers

If you don't set up the layers then the effects won't work.&#x20;

In the inspector, create two physical layers. One for the player and one for the projectile.\
You can just click any GO in your scene and add them from there: ![](https://2791585758-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FE8bOcbAuH0ZMX3MgiT9p%2Fuploads%2FhSuNzg0zIQJEj6NIrGb6%2Fimage.png?alt=media\&token=adac6786-94ea-4396-b128-85732a51300c)

Then in the physics settings, set the new layers as follow:\

Make sure you assign the Player layer to the player GO in the scene and its children.

Finally, assign the projectile layer to the object spawner prefabs in this folder, and also to the prefab located in the scene.

#### Open the scene

Launch the scene CollisionBasedEffects.unity located in:

*ProcedurallyPropagatingEffects/Scenes/CollisionBasedEffects.unity*

#### Controls

* Move around with WASD&#x20;
* Look around with the mouse
* Fire a projectile that will spawn an effect with Left-Click
* Change effect by pressing 1, 2 or 3 (not on the numpad)

### Alternative

From version 1.0.1 and above, you can also open the scene *ProcedurallyPropagatingEffects/Scenes/ClickBasedEffects.unity* and enter play mode.\
There you can move around the camera like you would in the scene window, and left click to spawn some ants.

<br>

You can customize the effects by modifying the prefabs located in:

*ProcedurallyPropagatingEffects/Prefabs/ObjectSpawner*
