The World Particle Collider is used to collide particles against other Colliders in the scene.
Property: | Function: |
---|---|
Bounce Factor | Particles can be accelerated or slowed down when they collide against other objects. This factor is similar to the Particle Animator’s Damping property. |
Collision Energy Loss | Amount of energy (in seconds) a particle should lose when colliding. If the energy goes below 0, the particle is killed. |
Min Kill Velocity | If a particle’s Velocity drops below Min Kill Velocity because of a collision, it will be eliminated. |
Collides with | Which Layers the particle will collide against. |
Send Collision Message | If enabled, every particle sends out a collision message that you can catch through scripting. |
To create a Particle System with Particle Collider:
If Send Collision Message is enabled, any particles that are in a collision will send the message OnParticleCollision() to both the particle’s GameObject and the GameObject the particle collided with.
