Disable shaders, GUI and AI

[danielniccoli]

This does disable shaders, GUI and AI. Because it writes to the processes memory, it works only on builds where we know the exact memory address. It also only works on the dev build, because the release build is missing the code that disables the AI.

This effectively replaces pressing F5, F8 and F12. It also helps with getting a better screen cap, because it stops entities from moving, if the motion is caused by AI.

function OnWorldInitialized() -- This is called once the game world is initialized. Doesn't ensure any world chunks actually exist. Use OnPlayerSpawned to ensure the chunks around player have been loaded or created.
    --[[
        The following code disables shaders, GUI and AI.

        While shaders and GUI can be disabled in the release build as well, only the dev build has the debugging feature to disable the AI.

        Due to direct memory address write operations, only known builds on known operating systems are supported.
        Adding new builds or operating systems is easy, if someone supports us with the research.

This is awesome. Did you use cheat engine to find these addresses?

I'm currently adding a settings menu, once that is done i will look into adding this. There will be advanced options to enable/disable a lot of stuff, and this will be a nice addition to the options.

Yes, I used Cheat Engine. Amazing tool.
