Help with Exp Bar

Unity Engine
1

Hi, im working on an Experience bar and i need some help to make the bar grow with my currentExp and have a max distance… here is the code:

var curExp = 0;
var curLevel = 0;
var ExpToLevel = 99;

var ExpBarLength = 0;
var ExpBarMaxLength = 90;
var ExpBarLength2 = 1;

ExpBarLength = curExp * ExpBarLength2;
function OnGUI () {
	(GUI.Box(Rect(30,600,ExpBarLength,20), curExp + "exp"));
	(GUI.Box(Rect(50, 100, 50, 25), "lvl " + curLevel));
	
	if (ExpBarLength > ExpBarMaxLength) {
		ExpBarLength = ExpBarMaxLength;
	}
	
	
	if (curExp > ExpToLevel) {
		curExp = 0;
		curLevel = curLevel + 1;
		ExpToLevel = ExpToLevel + 50;
		print("Level Up!");
	}

}

Can you help me with this? By the way the code is not fully completed just need help with that…

what more do u want to do in this? I think it works

Use GUI.DrawTexture() instead of a box.

var expTexture : Texture;
var curExp : float;
function OnGUI()
{
    GUI.DrawTexture(Rect(10, 10, 60, curExp), expTexture);
}

// So when you modify curExp your size of texture will also change

// This is for demo purpose to show it is working
function Update()
{
    curExp++;
}

The script works but not fully… Couse the bar can go past the whole screen. Ill test zine92’s code
THX…

If you need to maintain the length of the bar I think you should replace this part of code

(GUI.Box(Rect(30,600,ExpBarLength,20), curExp + "exp"));

change ExpBarLength with your variables which describes this

max exp bar length * current experience / max experience

Personally i think your if loops should be working. The one that checks if experience is more than certain amount. My script do not have experience checking.

Well, i realized there’s a typo in my previous script and as a apology, i made a new one. I packaged it and you just import the package and put the prefab on stage to try it out. Make sure maxExp is not 0.

mm, I like his tutorials… But i dont like C#. I dont know why but i just like writing in javascript more. Is it a MUST to learn C# too?

10

I would say that, to migrate to C# would be the best thing you can do. Because, although there is nothing wrong with JavaScript, it’s a LOT more simpler, in C#, to debug, as you have a lot more options open to you. And finding silly things like mis-typed variables etc won’t be an issue in C#, because it will complain about it :slight_smile:

11

In Unity, C#* JavaScript are very similar cause the library are the same. Matte005 ? have you resolved your issue ?

12

Nope. Not a must to learn c# if you are just learning the basics of Unity. I had no problem with js too. Just started learning C# and having no problem. I think doing things in js is more faster (the more prototypical way) and in c# is more neat. Both works around the same.
