I'm using the following code but it's not working, block is not disapearing on impact.

Code:

---

 
action test_box_action 
{
	my.enable_impact = on;
	
}


function vehicle_impact_event 
{
	ent_remove (you); 
	wait(1);
	
}



action vehicle_collision_action
{
 	my.enable_impact = on;
	my.event = vehicle_impact_event;
	
}




//in my car action i have 
vehicle_collision_box = ent_create ("car_cbox.MDL", p_vehicle.x, vehicle_collision_action);








// and this in a loop
			temp.x = 0;
			temp.y = 0;
			temp.z = 0;
		        // update collision box position			
			vec_rotate(temp, p_vehicle.pan);  //   This rotates the vector offset so
			// that it is relative to the my entities  
			// position, not to world coordinates...  
			vec_add(temp.x, p_vehicle.x); // Add entities coordinates to it... 
			vec_set(vehicle_collision_box.x, temp.x);  // Set entity to calculated position...    
			vec_set(vehicle_collision_box.pan, my.pan);  // Set entity angle to my angle...
