Use particles as Trigger (Shuriken)

Hi guys,

is it possible to use a particle (or multiple) as a kind of trigger System? I’ve got a shuriken that emits particles on KeyInput which then fall down due to gravity. Everything fine here. But I want to change some properties of other Gameobjects (like position…) when the particles reach a specific height. But dont stop them from falling as it happens when I use a Collider…
I hope my question ist clear? I have no idea right now :confused:

You can use the newly implemented ‘particle callbacks’ as demonstrated here:

You can write a script to attach to the ‘colidee’ that would detect when a particle has collided, the documentation for that is here:

http://docs.unity3d.com/Documentation/ScriptReference/ParticleSystem.GetCollisionEvents.html

Use onParticleTrigger().
I think this would be more suitable to your case.
