Kill Shape Block reference
The Kill Shape Block defines a shape that destroys particles that collide with it. The Block destroys particles by setting their alive
attribute to false
.
If you change the Behavior property of the block, the Block changes to the following:
- A Collision Shape Block if you set Behavior to Collision.
- A Trigger Shape Block if you set Behavior to None.
Block compatibility
You can add the Kill Shape Block to the following Contexts:
To add a Kill Shape Block to your graph, open the graph element menu as described in Adding graph elements then select Collision > Kill Shape.
Block settings
Property | Type | Description |
---|---|---|
Shape | Enum | Sets the shape for particles to collide with. For more information, refer to the Shape dropdown section. |
Mode | Enum | Specifies how particles interact with the collider. The options are:
|
Radius Mode | Enum | Sets the collision radius of the particles. The options are:
|

Shape | Description |
---|---|
Sphere | Sets the collision shape as a spherical volume. |
Oriented Box | Sets the collision shape as a box volume. |
Cone | Sets the collision shape as truncated cone volume. |
Plane | Sets the collision shape as a flat plane with infinite length and width. |
Signed Distance Field | Sets the collision shape as a signed distance field (SDF), so you can create precise complex collision with an existing asset. To generate a signed distance field asset, use the SDF Bake Tool or an external digital content creation (DCC) tool. |
