Help/Support error: use of undeclared identifier 'mp'

Ted2 · October 3, 2017

Heya

So I'm trying to add a hook into the MM, since this worked on shmoo's MM, but the mm is buggy, I wanna do it on Arthurs.

This is the code I'm using:

    int (*orig_func)(void *self);

    int new_func(void *self)
    {
        
        BOOL featureIsActive = [menu getBool:@"k02BasicSwitcher"];
        
        if (featureIsActive)
            return 999999;
        else
            return orig_func(self);
    }

%ctor
{
    NSDictionary *hacks =
    @{

        @"k02BasicSwitcher":@{
            @"offsets": @[@"0x0ffset"],
            @"desc": @"This will make the enemy dead within one hit.",
            @"label": @"One Hit Kill"
            },
    };


MSHookFunction((void*)[mp calculateAddress:0x0ffset], (void*)new_func, (void**)&orig_func);

What's wrong?

Why I'm getting the error?

You're getting this error because the given example for hooking has not been updated to conform with the rest of the changes made to the library and template.

You can work around this issue by trying the following :

// You must do this if you're working with a 64-bit binary because of ASLR
MSHookFunction((void*)(_dyld_get_image_vmaddr_slide(0) + 0x000000000), (void*)newFunction, (void**)&oldFunction);

//Otherwise, you can omit "_dyld_get_image_vmaddr_slide(0)"
MSHookFunction((void*)(0x000000000), (void*)newFunction, (void**)&oldFunction);

Moreover, if you're only applying a hook, you don't need to define offsets or patches. All you need is the label and description.
