Script help

[DRedshot]

thanks you two, you've helped me out alot!
Also, after reading YourComputer's post about the banging door, can any function have a randomly chosen signature, such as
(string &in asEntity) can be (string &in AnythingIWant)
even if it's an interact callback. Finally, i can't see how the string carries on to the next function, where it says (current_door = "xxxxx")
how does this go onto the next function? is it sent across with the AddTimers?
Thanks for all the help, and sorry for all the questions. You can probably tell that i've not done much programming before, but i pick it up quickly so i appreciate the help.
