Put the call script into an event on your start map and make it a parallel process. I can't remember the call script off the top of my head. It's in the demo somewhere, just check the script for the guy that asks if you want turn hud on or off, and use the call script for on. This is what i did and it works like a charm. Dont have access to RMXP atm, but if no-one else answers when i get back i'll post in more detail for ya later
