Here's a basic kick script if you don't want a specific player going into your levels. Feel free to use it.
PHP Code:
function onPlayerEnters() {
temp.pl = findplayer("Graal1008419"); //The account name can be changed.
if (temp.pl.level == "era_grief-test.nw") { //The level you don't want them to be in.
temp.pl.setlevel2("era_present_00-00.nw",30,39); //the level you want them to warp to.
}
}
