Are the certain things within the UI that can't be changed ?
For example on the main screen. The inner rectangle (rectangle-1) and the outter grey the goes the width. I don't find either of those in the default skin directory .
The rectangle is actually built into xlobby. That's why you cant find the image anywhere. In order to get it on other screens, enter the skin mode, copy it go over to the screen you want it on and paste it. That's about the only thing you cant edit; aside form the actually programming of xlobby that is. hehe good luck!
There is practicall nothing you cant edit eihter via the Skin editir/ set up Event maanegr or last resort by hand in the .xml files.
Overlays are just "standard" screens with any normal functionality that when you display them DO NOT display the background. I use them alot.
TIP us ethe actual backround you want to overlay on to so that you can position things correctly
use skin editor to make/modify them. Thre is one final important thing. If from the overlay xou goto another screen. you must issue a CLOSE overlay command, ohterwise Xlobby rgink the overlay is still active.
So in the event manager a goto event will alwasy have two xlobby commands
