Particles colliders do not be detected by bullets with 'continuos dynamic' collision detection.

Questions & Answers

Hello,
I’m feeling very tired and demotivated :frowning:

I have spent an entire day to understand all about the collision detection in order to solve my problem (bullets were passing through enemies).

After setting up my bullet’s rigidbody to ‘continuos dynamic’ the result is:

  1. All the collisions are perfectly detected by the AI enemies.
  2. Some collisions with particles ARE NOT DETECTED by particle colliders (In the particle system: collision quality ‘high’, enabled dynamic colliders).

Really I,m very tired because I’m started to think that problems are not about my knowledge,
but about an exaggerated complexity of the Unity engine.

Thanks.

Thanks for reply @SmokeyWitch , the config its quite the same.
-The Acceleration of bullet’s rigidbody is 1.
-The velocity of bullet’s rigidbody is 600.
-The ‘lifetime loss’ of particles is 1 because they are destroyed immediately with the bullet’s contact.

This is the situation:

your game is 3D. so it depends on the shape you used for your particle system and collider bound of the bullet. As you said “Some collisions with particles ARE NOT DETECTED by particle colliders” there isn’t any problem collision detection. some particles are out of the bullets collider bounds.
