Help/Support MSHook Patcher problem

Goggwell · August 12, 2015

Hey guys. After hours of coding and help from various people, I finally got my Patcher to compile. Problem is, the hack makes the game crash after I swipe two fruits.

My iPhone specs:

6+ running ARM64

Here's the code (Don't steal my offsets)

My Tweak.xm

#include <UIKit/UIKit.h>
#include <CoreFoundation/CoreFoundation.h>
#include <substrate.h>
#include <Foundation/Foundation.h>

#define PLIST_PATH @"/var/mobile/Library/Preferences/com.goggwell.FruitNinja.plist"

inline bool GetPrefBool(NSString *key) {
    return [[[NSDictionary dictionaryWithContentsOfFile:PLIST_PATH] valueForKey:key] boolValue];
}

bool (*old_IsTimedGamev)(void *ptr);
int (*old_WaveManager9SpawnBombEiP12SPAWNER_INFOi)(void *ptr);
int (*old_WaveManager17GetCriticalChanceEi)(void *ptr);
int (*old_Components5Score8LifeLostE8_Vector3IfEiP6Entity)(void *ptr);
bool (*old_Components5Score9IsNewBestEv)(void *ptr);
int (*old_AIManager10Tournament11GetEntryFeeERKN6Mortar11AsciiStringE)(void *ptr);


bool IsTimedGamev(void *ptr) {
    if(GetPrefBool(@"kTimed")) {
        return FALSE;
    } else {
        return old_IsTimedGamev(ptr);
    }
}

int WaveManager9SpawnBombEiP12SPAWNER_INFOi(void *ptr) {
    if(GetPrefBool(@"kBomb")) {
        return 0;
    } else {
        return old_WaveManager9SpawnBombEiP12SPAWNER_INFOi(ptr);
    }
}

int WaveManager17GetCriticalChanceEi(void *ptr) {
    if(GetPrefBool(@"kCrit")) {
        return 100;
    } else {
        return old_WaveManager17GetCriticalChanceEi(ptr);
    }
}

int Components5Score8LifeLostE8_Vector3IfEiP6Entity(void *ptr) {
    if(GetPrefBool(@"kLost")) {
        return 0;
    } else {
        return old_Components5Score8LifeLostE8_Vector3IfEiP6Entity(ptr);
    }
}

int Components5Score9IsNewBestEv(void *ptr) {
    if(GetPrefBool(@"kBest")) {
        return TRUE;
    } else {
        return old_Components5Score9IsNewBestEv(ptr);
    }
}

int AIManager10Tournament11GetEntryFeeERKN6Mortar11AsciiStringE(void *ptr) {
    if(GetPrefBool(@"kFee")) {
        return 0;
    } else {
        return old_AIManager10Tournament11GetEntryFeeERKN6Mortar11AsciiStringE(ptr);
    }
}


__attribute__((constructor)) void DylibMain()
{

    MSHookFunction(MSFindSymbol(NULL,"__Z11IsTimedGamev"),(void *)IsTimedGamev,(void**)&old_IsTimedGamev);

If anyone could help me out that would be much appreciated

WaveManager9SpawnBombEiP12SPAWNER Is not an integer. BX LR or (void) WaveManager9SpawnBombEiP12SPAWNER { return; }

It worked on my Tweak though

Change *ptr to *self

Use what I have you for an example

Goggwell · August 12, 2015

Change *ptr to *self

Ok I'll try

I did, but it didn't compile and when it did, it crashed my game

Just use the code as an example. Nothing else. Also do what z0ne said, *self. It was in my example. Also it maybe your function.

try thes ...

if(GetPrefBool(@"kBomb")) {
return 0;

to

if(GetPrefBool(@"kBomb")) {
return -1;

and do't put popup MGS

hook appdelegate

-(void) bla bla ....

I made one with 0 already. That's not the problem.
