A little help needed

Unity Engine

Hiya

I am getting an object reference error on my code within the OnGUI method but I was wondering on what I need to do here.

I do want to load the textures on screen but without the error that keeps popping up.

using UnityEngine;
using System.Collections;

public class scriptTest : MonoBehaviour {
	
	public Texture2D[] circles = new Texture2D[7];
	public int level = 0;
	public int counter = 0;
	
	// Update is called once per frame
	void Update () {
	
		circleFilled();
		
	}
	
	void circleFilled(){
			
		if(counter >= 1000){
			
			counter = 0;
			level++;
		
				OnGUI();	
		}
		
		if(level >= 6){
			level = 6;
			counter = 0;
		}
	}
	
	void OnGUI(){
		if(level == 0) GUI.DrawTexture(new Rect(20, 10, 15, 30), circles[0]);
		else if(level == 1) GUI.DrawTexture(new Rect(20, 10, 15, 30), circles[1]);
		else if(level == 2) GUI.DrawTexture(new Rect(40, 10, 15, 40), circles[2]);
		else if(level == 3) GUI.DrawTexture(new Rect(60, 10, 15, 50), circles[3]);
		else if(level == 4) GUI.DrawTexture(new Rect(80, 10, 15, 60), circles[4]); 
		else if(level == 5) GUI.DrawTexture(new Rect(100, 10, 15, 70), circles[5]);
		else if(level == 6) GUI.DrawTexture(new Rect(120, 10, 15, 80), circles[6]);	
		
		/*
		
		
		 */
	}
	
}

Some tips are grateful.

Thanks

I don’t believe you need to call the OnGUI function inside your CircleFilled function. Don’t know if it fixes your problem or anything.

You really should never call OnGUI from another method, as i am sure bugs and errors will pursue.

Right that sorted it and I’ll remember it next time. Thank you both so much.
