public void SetCollider (int index, Component collider);

파라미터

index The Collider entry to assign.
collider The Collider to associate with this trigger.

설명

Sets a Collision shape associated with this Particle System trigger.

If the index is greater than the number of Colliders currently assigned to the Particle System, Unity adds empty entries to ensure the list is large enough.
