Question by Bengooch7 · Jul 24, 2015 at 09:15 PM · javascriptscript.boolean

Why is this boolean value changing?

Is it not possible in UnityScript to change the value of a boolean variable with the NOT operator?

This is what I would expect:

 var x = true;
 var y = true;
 
 var x = !y; 
 //variable x is now false


Is this not something you can do in UnityScript? I believe it works in regular JavaScript...

You are redeclaring variable x, otherwise your example will work. The problem is that your variable is probably overridden from inspector. Im a c# programmer mostly, but i tried this example and is works perfectly.

 private var x:boolean = true;
 private var y:boolean = true;
  
 private var a:boolean = !y;
 
 private function Start():void{
     Debug.Log(a); //prints false
 }

I actually put the var on here by accident, I didn't have it in my script I was working off of.

I would guess you may be right about the inspector overriding the value. I've had a ton of problems with that! I hate how Unity serializes all of my public variables, as I have several scripts that all share information with each other.

Unity would be pretty broken if it didn't, since otherwise any script change would destroy all of your carefully-set-up public variables on all objects that used that script. But you can use the NonSerialized attribute if you want a variable to be public but not serialized.

Same with private, if you want to serialize variable, use [SerializeField] before private.

Sure you can. It works as expected, though you need to remove "var" from the third line since you can't declare the same variable twice.

Remove the var in "var x = !y;"
