you talking bypass codes or patches? as i would be happy to teach bypass codes to you, i know how to do patch codes alse but im abit new to it

Bypass codes are super easy but I am afraid you have posted this in the wrong section. Anyways if you are looking for how to code menus you will first need to know the dvars.

Some things you will need can be found here:

Lets say you want to set godmode when you press select you would:

    

bind button_back "god"

For noclip you will do

    

bind button_back "noclip"

If you want to use multiple you can bind different buttons etc

    

bind dpad_up "god"

bind dpad_down "noclip"

With this code it will be set so that when you press up on the dpad you toggle godmode, and when you press down on the dpad you toggle noclip.

Hope this helps
