Put GameObject array into Transform Array?

Hi there!

So, I made a Waypoint Walking script, and I cant seem to figure how to make it add Waypoints with a certain tag, then put it into a transform array? How can I do this,
This is what I have

//Made by SirMcsquizy

	public  static Transform[] Waypoints;
	public float moveSpeed = 5;
	public float  rotationSpeed = 5;
	public Transform Thing;
	public static bool IsIdle = true;
	public bool PointSet = false;
	public Transform CurrentWaypoint;


	void Awake()
	{
	

	
	}

	// Update is called once per frame
	void Update () {
	

			Debug.Log ("I found Waypoints");
			if (IsAlive == true) 
		{
			//Debug.Log ("I'm Alive");
			if(PointSet == false)
			{
				CurrentWaypoint = Waypoints[Random.Range (0, Waypoints.Length)];
				PointSet = true;

							
			}
		
		if(IsIdle == true)
			{
				if(PointSet)
				{
					Debug.Log ("I am moving");
					Thing.position += Thing.forward * moveSpeed * Time.deltaTime;
					Thing.rotation = Quaternion.Slerp (Thing.rotation, Quaternion.LookRotation(CurrentWaypoint.position - Thing.position), rotationSpeed * Time.deltaTime);

					if(Vector4.Distance(Thing.position, CurrentWaypoint.position) < .1f)
					{
						
						PointSet = false;
						
					}
				}

			}
	
		}

	}
}

If Anyone can help me that would be great!

Thank you

You will need to use the GameObject.FindObjectsWithTag function. This returns an array of game objects with the given tag. I would call it inside your Start function just the once, unless you’re adding waypoints dynamically while the game is running.

Then you’ll either need to:

  • change your ‘waypoints’ array to be an array of GameObjects, that can be set directly to the value that FindObjectsWithTag returns. Your line of code that reads the current waypoint would then have to do CurrentWaypoint = Waypoints[bla].transform
  • or, once you’ve got the list of GameObjects, read the transform from each one and store it in your waypoints array

I’d go for the first option - its simpler! :slight_smile:
