check if agent reach destination

I want to check if agent position reach destination. i already checked with Debug.Log, the result is (tagent.position.x==dest1.position.x && tagent.position.z==dest1.position.z) both already has the same value (see pic below, 3rd and 4th log) but “REACHED” wasn’t shown on console, please help67519-aa.png

private NavMeshAgent agent;
	public Transform dest1, dest2, tagent;

	void Start () {
		agent = GetComponent<NavMeshAgent> ();
	}

	void Update () {
		if (Input.GetMouseButtonDown (0)) {
			Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
			RaycastHit hit;
			if (Physics.Raycast (ray, out hit)) {
				if  (hit.collider.tag == "group1") {
					agent.SetDestination (dest1.position);
					Debug.Log ("dest "+dest1.position);
					Debug.Log ("tagent"+tagent.position);
					if(tagent.position.x==dest1.position.x && tagent.position.z==dest1.position.z)
						Debug.Log ("REACHED");
				}
			}
		}
	}

First, if I understand your statement and your image, the 3rd and 4th messages do not reflect the same position because the Y values are different. Oh, wait, I see you don’t care about the Y value in your code, so ignore that… :wink:

Second, attempting to compare floating point values for equality is a recipe for disaster. Instead of determining if 2 floating point values are exactly equal, you should see if they are “close enough”. You can do that any number of ways, but here’s a simple method:

float closeEnough = 0.005;
if (Mathf.Abs(tangent.position.x - dest1.position.x) <= closeEnough && Mathf.Abs(tangent.position.z - dest1.position.z) <= closeEnough
{
    // the positions are within "closeEnough" distance
}
