OnTrigger ignoring all collisions but the first

Hi everybody:

I have a huge problem. I’m trying to implementing a waypoint AI system for my racing game. I have all the waypoints in my circuit stored in a list, and in the OnTriggerEnter(), when it arrives to the first waypoint, the target of my AI car point to the next waypoint. Also, when OnTriggerExit() is active, it add 1 to the variable that control the target to be pointed. But it doesn’t works furthermore, only with the first collision. Here are my codes:

private Transform targetObject;
private int i = 0; // This variable will control the current waypoint to follow
public List<Transform> waypoints;

private KartController kart;

void Start () 
{
	// keep a reference to the kart component
	kart = GetComponent<KartController>();
	targetObject = waypoints *;*
  • }*

void OnTriggerEnter(Collider other)

  • {*
  •   if (other.tag == "Waypoint") {*

  •   	targetObject = waypoints [i+1];*

  •   }*
  • }*
  • void OnTriggerExit(Collider other)*
  • {*
  •   if (other.tag == "Waypoint") {*

  •   	i++;*

  •   	return;*

  •   }*
  • }*
    }
    Can you help me? Thanks a lot!

The code that you posted works perfectly,
Just make sure that your Character has a rigidbody (you can untick Use Gravity),
And make sure that the Collider that is attached to your Character has “Is Trigger” Checked.
