Making a particle emitter collide with a rigidbody object?
Hi,
I have a particle emitter that has a world particle collider attached to it, "send collision message" is enabled. I have a box with a mesh collider and rigidbody aswell as this script attached to it...
function OnParticleCollision (other : GameObject)
{
var body : Rigidbody = other.rigidbody;
if (body) {
var direction : Vector3 = other.transform.position - transform.position;
direction = direction.normalized;
body.AddForce (direction * 5);
}
}
The particle is definitely hitting the box but its not moving the rigidbody what so ever. Any idea why this is?
Thanks.
@coolkid808 It might not be enough force to move your object, have you tried increasing the force value from 5 to something extreme like say...1000. If your player still does not move, there is another problem(unless your players mass is really high). Have you debugged from inside the function to ensure a collision is happening? Put a debug log or print inside of the conditional if(body){ } and see if it prints to the console.
Thanks hijinx but i followed aldo's method and it fixed the problem
This script must be attached to the particle system, not to the rigidbody. If you want to add a script to the rigidbody instead, it should be:
function OnParticleCollision (other : GameObject){
var direction : Vector3 = transform.position - other.transform.position;
rigidbody.AddForce (direction.normalized * 5);
}
The main difference between both versions: in the first version (particle script),
any rigidbody will be affected by
this particle system; in the 2nd version (rigidbody script, like above),
this rigidbody will be affected by
any particle system that has World Particle Collider and Send Collision Message enabled.
Thanks Aldo, I tried both methods, the first didnt seem to work, but when i attached the second script to the rigidbody as you suggested it worked perfectly. Thanks.
