Help/Support Fishhook Unity global-meta methods

[lockdownderp 5 iPhone 8 16.1.2]

Is it possible to fishhook the methods that are found in global-meta?

Ive tried using the symbols like Var$$GetGems for example but it doesn't work.

 

#include <substrate.h>
#import <fishhook.h>

static int (*orig_gems)();

int my_gems() {
        return 9999;
}

%ctor {
	rebind_symbols((struct rebinding[1]){{"Var$$GetGems", (void *)my_gems, (void **)&orig_gems}},1);
}

What is a fishhook?

Also, note that "Var$$GetGems" is NOT a symbol, this is il2cppdumper's way of outputting it, which means you can't hook by that!

Originally it's sub_x, so there are no symbols which means you gotta hook by it's offset.

Fishhook is the theos-jailed version of mshookfunction. 
 

Ok so its not possible to do then as you cant hook sub_x on theos-jailed

@Zahir i saw @Ted2 mentioned you in one of his other posts about sub_x and theos-jailed.

Is it possible to hack sub_x on theos-jailed? If so can you please share how so i can release some hacks

You can, by directly patching the binary.
