Question by Lucas.Giancola · Mar 27, 2014 at 02:47 AM · collisioncollidermesh

Mesh and Sphere Collider Not Registering

Alright, so I am trying to learn the basics of Unity so I made a 3D level in Blender for my character to walk around in. It works perfectly but when I add my bullet into the level, it just bounces off the walls instead of disappearing.

 void OnCollisionEnter(Collision col)
 {
     Debug.Log("Hit!");
 }

I have this section located in my Bullet class. The bullet GameObject has a rigidbody, and the level has a mesh collider. Please help I cannot figure this out and it would be gret to move forward! Thanks in advance.

Colliders are supposed to collide and react accordingly, not disappear upon collision. If you want it to disappear, you have to make it disappear.

@Lo0Nuhti$$anonymous$$ sorry... I meant I want to have the bullet disappear on collision and I have that code implemented but the actual collision is not registering

This script is attached to your bullet, and when your bullet hits a wall and bounces off of it the Debug isn't printed to your console?

I believe collisions only work when both objects in the collision have rigid bodies Try adding one to the wall to.

@hero_kenshin Scroll down a little way on that page to where it talks about Static Colliders

Thanks for all your help... I ended up adding a few more components to each GameObject and changing some of the setting and I got it working!
