You can do that by editing the GANIs with the Sprite sheet, but rename them something besides Walk.gani (for example), name them like Serv-walk.gani and upload them.
Then you can do a script in your system NPC like:
PHP Code:
function onCreated()
{
replaceani(walk,"Serv-Walk");
}
I can't recall wether to put .gani in that second parameter or not
