Question by larkeith · Jun 16, 2016 at 08:21 PM · 2dcollisionparticlesparticle systemparticle collision

Disable collisions between particles

I'm currently trying to disable particle collisions with other particles in a 2D game, however I need it to still trigger collision events with other objects.

I have it set to only collide with default, while the particle system and its subemitter are in their own layer "Particles".

The Collision tab parameters are:

Collision Mode: World / 2D

Visualize Bounds: False

Dampen: 0

Bounce: 0

Lifetime Loss: 0

Min Kill Speed: 0

Radius Scale: 1

Collides With: Default

Enable Dynamic Collide: True

Max Collision Shapes: 256

Collision Quality: High

Send Collision Message: True

I've tried changing each of these settings, and none of them completely prevent bouncing between particles.

This is what the particle system looks like with collisions enabled: alt text

This is what it looks like without collisions (What I want, but it doesn't send collision triggers): alt text

I'm probably just missing something obvious, but is there any way to make particles collide only with non-particle objects, or only send trigger messages on collision?
