Unity 2D粒子碰撞未发生事件

Question

When I turn on particle system in my 2D game, and check the collision button in Inspector window, I expect to get an event On-Particle-Collision , but it never happens!

I even added an extra thing named WorldParticleCollider , but also, no collisions.

I have tried even adding this WorldParticleCollider to the enemy(just for no reason), and sure it did not work.

Why is this ?

Answer 1

According to this question at the Unity forums OnParticleCollision may not support 2D games just now.

according to Unity Roadmap, this feature will be available with Unity 5.3 (Dec 8, 2015).

Maybe you can use a 3D collider for your 2D game.

Remember the collider cannot be a trigger!
