Hi Crypton,
I tried it again with window and I didnt get it to work.
as you mentioned, window doesnt accept variables or decimals.

Maybe this code will help you.

Code:
BMAP* balken_attribut = "attribut.pcx";//pcx with 100x20
var willenskraft = 100;

PANEL* will_pan =
{
	pos_x = 0;
	pos_y = 0;
	hbar = 0, 0, 200, balken_attribut, 2, willenskraft;
	flags = VISIBLE;
}

function reduce_hp()
{
willenskraft -= 0.987;
}

function main()
{
...
..
.
on_t = reduce_hp;
}


This code is tested and should work like a comon healthbar.
Im also interested in knowing how to make a healthbar with window laugh
I will test some more but it seems that it wont work with window.
Anyway, I hope you can use the vbar code.

cheers
