I'm having a bit of trouble getting the Vector3 wayPointPosition to my other script called Walking and changing it into the Transform target. My troubles lie in the fact that I'm trying to grab this dynamic variable from WayPointPositioner (it changes depending on what object is clicked in the stage and whether the player overlaps with this waypoint) and import and use it in another script.
Below is the code I'm using.
WayPointPositioner
using UnityEngine;
using System.Collections;
public class WayPointPositioner : MonoBehaviour {
public Vector3 wayPointPosition = Vector3.zero;
private bool checkPlayerWaypointCollision;
void Start()
{
}
void OnTriggerStay2D (Collider2D other)
{
// Check if collision is occuring with player character.
if (other.gameObject.name == "Player")
{
checkPlayerWaypointCollision = true;
}
else
{
checkPlayerWaypointCollision = false;
}
}
//Check if object is clicked
void OnMouseDown ()
{
// If its the player, then return a new position for the player to move to for walking
// Else debug that its not so
if (checkPlayerWaypointCollision == false)
{
Debug.Log ("Object not colliding and retrieving position");
Debug.Log (wayPointPosition);
Debug.Log (gameObject.name);
wayPointPosition = new Vector3 (transform.position.x, transform.position.y, 10);
wayPointPosition = Camera.main.ScreenToWorldPoint(wayPointPosition);
}
else
{
Debug.Log ("Object is colliding, no movement needed");
}
}
}
Walking
using UnityEngine;
using System.Collections;
public class Walking : MonoBehaviour {
public Transform target;
public WayPointPositioner wayPointPosition;
public bool walkingAnimation = false;
private Animator anim;
void Awake ()
{
anim = GetComponent<Animator> ();
wayPointPosition = GameObject.FindGameObjectWithTag ("Waypoint").GetComponent<WayPointPositioner> ();
}
void Start ()
{
}
void Update ()
{
Debug.Log ("This is in Walking, WPP =" + wayPointPosition);
}
}
As you can see I'm trying to import the wayPointPosition from the seperate class which is attached to the gameobjects called "Waypoint" (In my current layout those are empty objects with circle colliders to check if they have been clicked). However when I run this, I am not getting my Vector, but I'm getting the name of the last waypoint in the hierarchy (I have currently 6 waypoints which can be clicked) and not a Vector.
I hope someone is able to help me / point out my mistake. I'm still learning C# so I might've made a strange / odd assumption which isn't working.
Kind regards,

It looks like invoking GameObject.FindGameObjectWithTag("Waypoint").GetComponent<WayPointPositioner>(); retrieves a component from the game object which matches the specified tag, as well as a type argument T which derives from MonoBehavior.
Calling this should actually give you an instance of your WayPointPositioner class, which you can then pass to whichever methods you want, and interact with its Vector3 however you would like.
