I have a missile object with a capsule collider. When I shoot the missile off, sometimes (about 50%) it will bounce off the mesh it collides with, instead of exploding. In my OnCollisionEnter method (on the Missile) I can see that the OnCollisionEnter method is not called - but surely if it bounces off the collision must be detected?
I had a similar issue with a prefab with more than one collider (on parent and child), where how the object hits another collider depends on which gets activated (only one had a scripted effect). But in this case I have only one collider, so this cannot be the issue.
Does any one have any idea what is going on, or how I could track down the cause?
Edit More info: I have continuous dynamics switched on on the missiles. The missiles are very small compared to the meshes they are hitting - could this be an issue?
Try using triggers instead and also make sure to use a non-kinematic rigid body
I tried it, but now sometimes (~50%) they just go right through the meshes... Is there anything else I can try?
sounds like you're moving too fast, increase the fixed time frequency or use raycast to detect collision or wait for unity 3 and use continuous collision detection
