Question by sam · Oct 24, 2010 at 05:03 PM · getcomponent

Access another script

Basically Im trying to access a function GetLives() in a script called obj. However Im having an error in my function update when I run the game.

using UnityEngine; using System.Collections;

public class PickUpController : MonoBehaviour { public int objCount; public GameObject playerHandle; GUISkin gskin;

 void OnGUI() 
 {
     if(gskin)
     {
         GUI.skin = gskin;
     }

     string guistring = "Candy: " +objCount;
     guiText.text = guistring;
     GUI.Label (new Rect( 20, Screen.height-230, 150, 250), guistring);
 }

 void Update()
 {
     playerHandle = GameObject.Find("Player");//reference to the Player GameObject within the scene
     obj other;
     other = playerHandle.GetComponent("obj") as obj;
     objCount= other.GetLives();
 }

}

...
playerHandle = GameObject.Find("Player");//reference to the Player GameObject within the scene

I tried to add this but im still getting this error in this line:

     other = playerHandle.GetComponent("obj") as obj;

Object reference not set to an instance of an object

    playerHandle = GameObject.Find("Player");
    obj other;
    other = (other)playerHandle.GetComponent(typeof(obj));
    objCount= other.GetLives();
