** I dont know if this is the right section, i dont find a request help one. Mods feel free to move my post thanks **

First i want to know if i can make a script o trainer like do this:
example.

" if Address(73B4C1C) = 1766523136 then
change Address(471A2C0) = 128
else
continue
endif
"

And the second thing is if i change some value how i can make it return to original value?
I mean i found the Shot address, so an example; shoting = value 1 and non shoting = value 0.
I set a hotkey to the value when i press "X key" it will change the address value to 1. But its doesnt return in like 10 seconds. How can i do it for return faster?
