Question by nikrath · Mar 23, 2014 at 07:11 AM · collisioncarhealth

Collision not working!!!!

I am making a car game where i want the cars health to be reduced on collision. I applied the health script to the mesh which has a box collider on it. The only other colliders are wheel colliders. But for some weird reason, there is no collision detected!! But the same script on objects outside my cars heirarchy work perfectly!! But the moment i out the code on something INSIDE my cars heirarchy, it doesnt work again. Therefore, i think my code is perfect, but theres something else that is wrong. Someone pls help me out!!!alt text

The main_chassis is the one that has a collider on it

Do you have colliders within colliders in your hierarchy. I had a problem with that.

I just seemed to have solved the problem partially, i applied the script onto the parent(the car itself), it detects now. But this poses another problem, because the wheel colliders are a part of the main object (car), it detects when the car is on the ground and then reduces its health...

maybe you shuld ignore reducing health when the hitted object is the ground.

  void OnCollisionEnter(Collision col) {
                 if (col.gameObject.name != "Ground") 
             {
                      health -= 1;
             } 
     }

O$$anonymous$$. Probably at this stage it may be good to look at a working example. Check out the Car Tutorial in the Assets store [Window > AssetsStore]. It is free. Just type in car tutorial in the search in the Assets Store.

I believe you may be passing through quicker than the OnCollisionEnter() method can calculate.

You should maybe change the method to...

     void OnTriggerEnter(Collider col)
     {
     if(col.gameObject.name == "$$anonymous$$ain_Chasis")
     {
     Debug.Log("you just went through the main chassis")
     }
     }



$$anonymous$$A$$anonymous$$E SURE YOUR COLLIDER CO$$anonymous$$PONENT IS SET TO "IsTrigger" on the "$$anonymous$$ain_Chassis" GameObject. The OnTriggerEnter() code should be applied to the object you are trying to pass through/collide with.

Hope that helps bud. Take care Gruffy
