Question by JawJaw · May 15, 2013 at 01:47 AM · particlecollison

Shuriken particles only detect collisions with non-moving objects?

I have a particle system generating a field particle with 0 speed (they just appear and then disappear after a few seconds without moving). The particle system's collision settings are set to "world" and to collided with everything. But when an object (with a collier and rigidbody) moves through the field of particles, the particles do not collide with it and the object passes right through without effecting them at all.

When I set it so that the particles have a speed when they start and I put the first object in the way of there direction, the collide as expected. However when the object starts moving against the flow of particles (toward the emitter) they begin passing though it again.

This makes me think that particles only detect collisions with non-moving objects, which seams odd. Is this is true? and if it is not, what am i missing?

Possibly relevant info:

Particle system:

Layer = Default

Simulation Space = World

Start Speed = 0

Inherit Velocity = 0


Particle Collision:

World

Dampen = 0

Bounce = 0

Lifetime Loss = 1

Min Kill Speed = 10000

Collides With = Everything

Collison Quality = High


Other object:

Collision Detection = Continuous

Layer = Default

Mesh Collider

Is Trigger = false

Convex = true

This is because of the way the particle system works. It simply does a Raycast along the velocity it's moving at. If you want proper, full fledged collision, you will need to use something that will probably not work in real time.

Damn. I was hoping it was a bug. Thanks anyway.

Have you tried non moving objects? Static objects? CharacterControllers? How are you moving the object? Is it translating to it's destination?
