Question by douglasfigueira · Apr 02, 2013 at 02:50 PM · tagsforeachfindgameobjectswithtag

GameObject.FindGameObjectsWithTag problems

I am trying to change some texture's offset values of some butterflies's wings . The wings are tagged as "wings".

When I run this script I receive this error: UnityException: You are not allowed to call this function when declaring a variable. Move it to the line after without a variable declaration. If you are using C# don't use this function in the constructor or field initializers, Instead move initialization to the Awake or Start function. ButterflyColor..ctor ()

 using UnityEngine;
 using System.Collections;
  
 public class ButterflyColor : MonoBehaviour {
  
     public GameObject[] wings = GameObject.FindGameObjectsWithTag("wings");
     
         public void SetButterfliesColorsValue(string myButterflyVal){
          
           foreach (GameObject wing in wings) {
        
  
                if (myButterflyVal == "blue") {
                wing.renderer.material.mainTextureOffset = new Vector2(0, 0);
                }
               else if  (myButterflyVal == "orange"){
                wing.renderer.material.mainTextureOffset = new Vector2(0.25F, 0);
                }
                else if (myButterflyVal == "yellow"){
                wing.renderer.material.mainTextureOffset = new Vector2(0.5F, 0);
                }
                else  {
                wing.renderer.material.mainTextureOffset = new Vector2(0.75F, 0);
                }
     }   
 }
     
 }

What is wrong?

Thank you in advance ;-)

Methods/functions cannot be called when declaring a variable. That is :

GameObject obj = GameObject.Find("Object");

will not work EXCEPT!!!! if you do so in a function.

 void Start(){
    GameObject obj = GameObject.Find("Object");
 }

will work. BUT!!! keep in mind the variable reference obj is destroyed at the end o fthe function so if you need outside of it you declare it outside the Start function.

For your case that goes:

 using UnityEngine;
 using System.Collections;
  
 public class ButterflyColor : MonoBehaviour {
   
    public GameObject[] wings;
    void Start(){
       wings= GameObject.FindGameObjectsWithTag("wings");
    }
    public void SetButterfliesColorsValue(string myButterflyVal){
       //Your implementation
    }
 }
