mono_invoke_method uses the following params:

Uh huh, thanks a lot for the reply.

Yes the address should work with 0x1, tested it with a couple of other stuff, but again the set_godmode may be needing an address to check if it's for the player or not, more specifically I guess :thinking:

It's a method as can be seen in a screenshot he showed on the Cheat The Game discord
I had him try/use 1 for the address in some debugmenu:addGold method (not the console) since it didn't seem like it should actually need an instance address for what it was doing and 0 didn't work but didn't crash either (at a guess likely a basic check simply because it wasn't made a static function in the source). It worked, so of course it was tried here as well. Not sure how many others he may have tried it with.

However I've never tried to pass a string to a mono method so i couldn't really figure this one out over discord, though I did suggest the obvious {type:vtString, 'on'} (seemed to break the monopipe ex) and writing a wide string to memory and passing the address as vtQword, as well as writing the length before the string as a word since I saw something like that in monoscript.lua (though I can't remember now if that was tried or if the obvious variations of mem+2 and length=chars vs length= bytes were tried)

{{type=vtString, value='on'}}

Should be the way to go with that then, or instead of 'on' try '1'.

The object param should be nil or an actual object, passing 1 would be giving it an invalid object unless CE does some vodoo behind the scenes with it. (Not too sure since I haven't really used the mono stuff much at all.)

You could use a tool like dnSpy to dig into this more to see what _godmode does with the value passed to it and such as well to know exactly what it expects aside from just it being a string type.

Thanks atom0s and FreeER, and I found with DnSpy these stuff:

I'm going to try the SetGodMode as I haven't seen it before using the Mono Features alone in the Class called: CheatsBridge.

And since it's a bool, I'm not quite sure what kind of vt I should use, I assume for the most It should be vtBoolean and a value of 1.

mono_invoke_method(nil, mono_findMethod('','DebugConsole', 'SetGodMode'), 1, { {type=vtBoolean, Value=1} })

Well that definitely shows _godmode using the object (this) though only to call other methods so can't say for sure whether those actually access the memory in any way. It also shows that it wants 'on', 'off', or 'toggle' which kind of explains why it takes a string rather than just a booean, since there are 3 values not just 2, though it also looks like it takes input straight from the user at a console without checking the input elsewhere to verify it makes sense.

As for a boolean, the CE vt type equivalent is vtByte. You can see the table at the top of monoscript.lua
