Using the actual template and not 'block.png' works.
You're pretty much on the right track from there. If you want to do small one-time modifications you can use 'useownprofile'. I.e:
PHP Code:
//#CLIENTSIDE
function onCreated() {
new GuiWindowCtrl("Test_Window") {
profile = GuiBlueWindowProfile;
useownprofile = true;
profile.transparency = 0.5;
x = 10;
y = 10;
width = 160;
height = 80;
text = "Window";
}
}
Included the template and other files.
