C# Boolean Doesn't Change Value

Questions & Answers

I have a script that changes the value of someBool depending on what mouse button was clicked and what value someBool has. But for some reason the value of someBool doesn’t change. As far as I can tell these if statements should be valid. Any idea what is wrong with this script?

    using UnityEngine;
    using System.Collections;
    
    public class SomeScript : MonoBehaviour {
    	public bool someBool;
    	// Use this for initialization
    	void Start () {
    	
    	}
    	
    	// Update is called once per frame
    	void OnGUI () {
    	  if (GUI.Button(new Rect(10, 70, 250, 30), "Click to Change someBool's value")){
    	       if(Input.GetMouseButtonUp(0)){
    			if(someBool = false){
    			someBool = true;
    				}
    			else if(someBool = true){
    			someBool = false;
    				}
    			}
    		   else if(Input.GetMouseButtonUp(1)){
    			if(someBool = true){
    			someBool = false;
    				}
    			else if(someBool = false){
    			someBool = true;
    				}	
    			}
    		}
    	GUI.TextArea(new Rect(10, 50, 40, 20), someBool.ToString(), 200);
    	}
    }

You would get a warning about the usage of “=” rather than “==” if you used that script. Read the warning and do what it says.
