ui.begin(g) --> TypeError: Cannot read property 'begin' of null

[Lykdraft]

Hey there, I am not sure if this is a Kha or Zui problem.
Maybe you can help.

I tried all kinds of variations. I can't call ui.begin(g).
Screen is black and Debug goes crazy.

Main:

 class Main {
    public static function main() : Void {
        System.start({title:"Project", width:1024, height:768}, initialized);
    }

    private static function initialized(window : Window) : Void {
       Assets.loadEverything(function(){
		    var game = new Project();
	   
        	System.notifyOnFrames(
            	function(fbs : Array<Framebuffer>) {
                game.render(fbs[0]);
           		}
        	);
        	Scheduler.addTimeTask(game.update, 0, 1 / 60);
    	});
	}
}

Project:

class Project {

	public var ui:Zui;

	public function new (){
		var ui = new Zui({ font: Assets.fonts.AndaleMono });
	}

	public function update():Void{
	}

	public function render (framebuffer:Framebuffer):Void{

		var g = framebuffer.g2;
		g.begin();
		g.drawRect(40,40,40,40,6);
		g.end();

		gui(g);
	}

	public function gui (graphics:Graphics){
		ui.begin(graphics);

		if (ui.window(Id.handle(),10,10,240,600)){
			if (ui.panel(Id.handle( {selected: true}),'panel',false,true)){
				ui.text('some text');
				ui.textInput(Id.handle( {text:'text input here'} ), 'textIn' );
				ui.check(Id.handle(), 'checkbox');
				ui.slider(Id.handle({value: 0.3}),'slider', 0, 2);
				Ext.colorPicker(ui, Id.handle());
			}
		}

		ui.end();
	}
}

Debug Console:

Any ideas?

Thanks & best,

I think I got it, sorry 'bout that...

[Lykdraft]

Weeeell, no I don't.
Can make it work in one file, can't make it work in two files.
If you have an idea, please shoot...

Hi, sorry but that's not enough info for me to tell what is wrong. Please try playing with the examples first at https://github.com/armory3d/zui/tree/master/examples, that should help.

Thank you.
I've got eveything rolling now.
