How it works

• A particle dies on collision with colliders, causing contacts to stop contacting each other, causing a boolean to enable.

• Merge the Animator Controller Collision Detection FX to your own FX Controller, using the Avatars 3.0 Manager tool.
• Drag & drop the Collision Detection prefab into the base of your Hierarchy.
• Right click and unpack the prefab, then drag & drop it onto your avatar.
• Parent Constrain it to any object in your avatars hierarchy as needed.
  • Note: You can move the object as well, but you'd have to repath the animations. One tool for this is hfcred's Animation Repathing tool

Note

When building for Quest, you will have to remove unsupported components and shaders

How to use

• After parent constraining/moving the object as needed, you can scale the object to obtain the desired range.
  • Note: To change the collision requirements, you can change the Layers in the collision module, or disable the collision module and enable the triggers module to select specific trigger colliders.

There are three important bools in your FX Controller:

• CollisionDetection/IsColliding: Whether or not the component is currently colliding with a collider.
• CollisionDetection/AlwaysReset: Whether or not IsColliding should go to false immediately after stopping collision, or stay on until the Reset bool is enabled.
• CollisionDetection/Reset: If CollisionDetection/AlwaysReset is false, this bool is used to reset the IsColliding state.
