Obtaining an array of positions from an array of gameobjects

I need a list of positions from several gameObjects tagged as “Wall”. I have searched all over, but only found specific answers to others’ problems.

Would I use ‘for()’ or ‘foreach()’ here?
In my LevelScript is:

public Vector3[] GroundWallPosition;

And in my otherScript

public GameObject[] GroundWallObjects;

	void Start ()
	{
		GroundWallObjects = GameObject.FindGameObjectsWithTag ("Wall");
		foreach (GameObject Wall in GroundWallObjects)
		{
			GetComponent<LevelScript>().GroundWallPosition[Wall] = GroundWallObjects[Wall].transform.position;
		}
	}

But obviously I cannot directly convert a gameObject into a Vector3, so how would I go about doing this?

This is pretty simple, one way you can do this…

public LevelScript script; //drag script into here

public GameObject[] GroundWallObjects;

void Start()
{
   GroundWallObjects = GameObject.FindGameObjectsWithTag ("Wall");

   for(int = i; i < GroundWallObjects.Length; i++)
   {
      script.GroundWallPostion _= GroundWallObjects*.transform.position;*_

}
}

You’re using a foreach loop as if it was an index based loop…

I don’t believe you can use “Wall” as an index.

Try converting to a Index loop

	public GameObject[] GroundWallObjects;
	
	void Start ()
	{
		GroundWallObjects = GameObject.FindGameObjectsWithTag ("Wall");
		for (int i = 0; i < GroundWallObjects.Length; i++)
		{
			GetComponent<LevelScript>().GroundWallPosition _= GroundWallObjects*.transform.position;*_

* }*
* }*

Well, you'll need another loop here, to compare each and every one of the vector, if one match, then you turn a boolean to true. Like so : bool wallHit = false; foreach (Vector3 wallPosition in GetComponent<LevelScript>().GroundWallPosition) { if (wallPosition == transform.position + new Vector3 (0, -1, 0)) wallHit = true; } if (wallHit) //deny movement
