Destroy Game object on Collider

Hi I've made fast driving object, and parent to it mesh collider ( plane, Convex+Is Trigger+ IsRigidbody)
My plane Collider deleting game object that I dont need after drive I use function:



void OnTriggerEnter(Collider other)
{

if (other.tag == "kill_me") {

Destroy(other.gameObject);

}

and everything seems to works fine, but if my main game object get fast speed some game object that have to be destroyed there isnt, it seems that collider sometimes work and sometimes don't

//edit
objects that I've destroyed are created first from Instantiate (tress, grass)

 

If the problem is that objects are moving too fast,
i've collected few solutions here:

Could also try increasing values here:
http://docs.unity3d.com/Manual/class-PhysicsManager.html

 

Yep, the issue is likely that the collision isn't being triggered. Check out the "Collision Detection" value on your Rigidbody object in the code documentation.

 

thank you I will try repair this
