[SCRIPT] Not sure what to title this actually!

Use global variables. It's quite easy actually.

When you have successfully accomplished the drainage in the other level, use SetGlobalVarInt("Drain", 1); in your script.

When you enter the hub again, within OnEnter() do something like this:

Code: (Select All)

if(GetGlobalVarInt("Drain") == 1) {
    DrainWater(); //Basically whatever effect you want to happen to indicate this or just change the water.
    SetGlobalVarInt("Drain", 0); //Just so this event does not happen if you re-enter again.
}
