Help/Support MSHookFunction issue. Game crashes instantly on launch

carpoa · November 30, 2023

I havent really got too much of a clue of what I am doing as I don't exaactly have a clear understanding off how MS stuff works. I follow this tutorial. Not sure if its out dated or not.

Code:

@import Foundation;
@import UIKit;
#import "Menu.h"
#import <substrate.h>
#import <mach-o/dyld.h>
#include <substrate.h>

/*%ctor {
    [APMenu.sharedInstance setTargetBinaryNamed:APEncrypt("@Framework/UnityFramework.framework/UnityFramework")];
    //[APMenu.sharedInstance setTargetBinaryNamed:@"Frameworks/FrameworkName.framework/ExecutableName"];
    //[APPatch writeToOffset:APEncrypt("10020081C") hexValue:APEncrypt("C0035FD6")]; // 

  	// obf long: get_Value)_
    //[APPatch writeToOffset:APEncrypt("024E038C") hexValue:APEncrypt("400680D21F2003D5C0035FD6")]; // 
    //iG_writeData((APEncrypt("1001D9900")), APEncrypt("20008052C0035FD6")); // writeData is still available for use
}*/
// ignore WIP
void infAutoSwipe()
{
}

bool ReturnTrue()
{
 return true; 
}

double ReturnNone()
{
 return 0; 
}
double multi()
{
 return 99; 
}

%ctor{
  [APMenu.sharedInstance setTargetBinaryNamed:APEncrypt("@Framework/UnityFramework.framework/UnityFramework")];
  //MSHookFunction(((void*)MSFindSymbol(NULL, "Alexplay.OilRush.App.Extraction.Machines.SwipeChargingMachineActionDetector$$SetSwipeProgress")),(void*)infAutoSwipe, NULL); // should give inf auto swipe
  MSHookFunction(((bool*)MSFindSymbol(NULL, "Alexplay.OilRush.App.Extraction.Machines.MachineUtils$$IsMachineOwned")),(bool*)ReturnTrue, NULL); // own all machines
  MSHookFunction(((double*)MSFindSymbol(NULL, "Alexplay.OilRush.App.Extraction.Machines.Upgrades.MachineUpgradeUtils$$GetPrice")),(double*)ReturnNone, NULL); // 0 upgrade price
  MSHookFunction(((double*)MSFindSymbol(NULL, "Alexplay.OilRush.App.Extraction.Machines.Machine$$get_ExtractionMultiplier")),(double*)multi, NULL); // 99x extract multi
}

If someone could help that would mean alot aswell as give a good explanation of function hooking etc. The tutorials available kind of confuse me.

Also some functions have custom types and or types that I cannot define by default so I am not too sure what to do about those.

Im no expert but worth a shot

Wouldn't you need to uncomment /*%ctor { so that @Framework/UnityFramework.framework/UnityFramework" can be used?

If you look down its already done again.
