Is it possible to re-use void? Let's say that in my game i have void that toggles police, but when it's called bool value isn't changing(i've wanted to find the value but it's unknown,tried all value types)

| If you mean a function that returns void then it can't return a boolean value since it's a void function i.e. return nothing.

Like in c++ i can use | Code: | | void(*Game_SetCopsEnabled)(bool AreCopsEnabled) = (void(*)(bool))0x6513E0; |
But idk how to use it Cheat Engine

With 7.3 you can do it with the new C compiler tags. Something like this. This is for the old school Minesweeper as just a simple/straight-forward example. This will call the 'ResetGame' function that resets the game board, flags and timer.

Cheat Engine 7.3 C compiler tag example to cast to and call a game function.
Creates a cave and invokes it as a thread. (Keep this in mind as it is not
designed to be threadsafe as-is!)
}
[ENABLE]
alloc(cave,1024)
createthread(cave)
cave:
{$ccode temp=eax}
// Create the typedef and cast the known function address..
typedef int (__cdecl *fResetGame)(void);
fResetGame ResetGame = (fResetGame)0x100367A;
// Call the ResetGame function..
ResetGame();
{$asm}
ret
[DISABLE]
dealloc(cave)
|
You can ignore the temp=eax tag for now, this is a bug in the current parser of the current 7.3 release. CE requires at least one register is used in 'ccode' tags at the moment which I believe will be fixed in the next update.
As mentioned in the comment tag, this is not considered threadsafe. Calling game functions from a new thread like this is prone to crashing if you are not careful, do not handle proper locking as needed, and so on. Be sure to handle any thread safety requirements accordingly.

Making bool in the function same as c++?
EDIT:
How to create one with bool?

DB pointed out on the other forum you posted in that you can add them to the typedef parameters.
If bool won't work use int and define true as 1 or 0xffffffff and false as 0.
Credit: DB, not my suggestion.
