Hey all! So halfway into development of this game, I got this error that I just can’t solve. I’m super new to C# as well so I might have written some unnecessary super long codes that could have been done in a single line. I’m getting there… hopefully.
I’ve been tested for a day. sometime it run perfectly but sometime it gaves me errors. But i guess, there is nothing wrong for code. What i did is this.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Unit : MonoBehaviour {
public GameObject Abintang;
public Pathfinding pathfinding;
public Transform target;
private float speed = 5;
private Vector3[] path;
private int targetIndex;
private bool checkSet;
public bool pathPending{
get{
return pathfinding.requestManager.isProcessingPath;
//return m_pathPending;
}
}
public bool hasPath{
get{
return pathfinding.m_hasPath;
}
}
public Vector3 destination{
get{
if (pathfinding.requestManager.isProcessingPath){
return pathfinding.m_destination;
}
if (path.Length == 0){
return transform.position;
}
if (pathfinding.grid == null){
return Vector3.positiveInfinity;
}
return pathfinding.m_destination;
}
set{
if (target != null) {
pathfinding.m_destination = target.position;
}
pathfinding.m_destination = value;
}
}
public float remainingDistance{
get{
if (pathfinding.m_destination != null){
return Vector3.Distance( pathfinding.m_destination , transform.position );
}
}
}
public bool isStopped{
get{
return pathfinding.m_isStopped;
}
set{
pathfinding.m_isStopped = value;
}
}
public float stoppingDistance {
get {
return pathfinding.m_stoppingDistance;
}

pathfinding.m_stoppingDistance = Vector3.Distance (pathfinding.m_destination, transform.position);
}
}
}

}
if (target != null) {

}
}
}
public void OnPathFound(Vector3[] newPath,bool pathSuccessful){
if (pathSuccessful) {
path = newPath;
Debug.Log ("Path Length = " + path.Length.ToString ());
StopCoroutine ("FollowPath");

}
}
IEnumerator FollowPath(){
Vector3 currentWaypoint = path [0];
targetIndex = 0;
while (true) {
if (transform.position == currentWaypoint) {

transform.position = Vector3.MoveTowards (transform.position, currentWaypoint, speed * Time.deltaTime);
checkSet = false;
//Debug.Log ("CheckSet = False");
yield return null;
}
}

and the error point to this line

Thanks for taking out the time to help me out!
