0 is a no show.

I cant get a single digit0 to display in my gui, it's a mud var I'm using,

PHP Code:


		
			
  this.clientr.mud.stats.curexp = 0;

I know 0 is null but why doesnt the gui still show 0?

EDIT :
Think I found a solution :

PHP Code:


		
			
 if (clientr.mud.stats.curexp == NUL) Master_Gui_Text_Exp.setText("EXP : 0/ " @ clientr.mud.stats.maxexp);

Still want 0 to show by itself.

In GScript2, 0 (NULL) is technically the variable not existing. When you set something to 0, it becomes unset, and unset variables automatically read 0.

it's the way the new engine works.

You can also use float(str). If you put a null string in there, it'll show up as 0.

PHP Code:


		
			
Master_Gui_Text_Exp.setText(max(0, currentexp));

Or even perhaps:

PHP Code:


		
			
Master_Gui_Text.setText(int(currentexp));

If you wanted a integer, yes. But his exp may (though I doubt it) include decimals.

I still like max() though. One of my favorite functions for math related things :)
I always see people doing all these integrated equations (the whole # > # ? # : # method) when they could simply use a combination of min(), max(), abs(), int() and the % symbol (not every case, obviously).

yes it includes decimals by increments of 0.2

Then

PHP Code:


		
			
Master_Gui_Text.text = float(clientr.mud.stats.curexp);
