Help/Support (Solved) Hooking in LGL Mod Menu

Parxdy · July 12, 2022

So im trying to make my OP mod menu for BTD6 over to android but its not letting me call a function. ive tried many ways with no luck using LGL Mod Menu.

im trying to call this void as i did in iOS version (this code is from android version)

// RVA: 0xC74969 Offset: 0xC74969 VA: 0xC74969 Slot: 57
public virtual void WinMatch() { }

and for the mshook i use simulation on ios version but there is also a update function aswell

// RVA: 0xC6A167 Offset: 0xC6A167 VA: 0xC6A167 Slot: 19
public virtual void Simulate() { }

// RVA: 0xC74246 Offset: 0xC74246 VA: 0xC74246 Slot: 53
public virtual void Update(float delta) { }

this is how i had my setup

auto WinMatch = reinterpret_cast<void(*) (void *)>(getAbsoluteAddress(targetLibName, 0xC74969));

void (*old_DT1)(void *instance);
void DT1(void *instance) {
    if (instance != NULL && WinToggle) {
        WinMatch(instance);
    }
    return old_DT1(instance);
}

MSHookFunction((void *)getAbsoluteAddress(targetLibName, 0xC6A167), (void *) DT1, (void **) &old_DT1);

also tried this

WinMatch = (void (*)(void *)) getAbsoluteAddress("libil2cpp.so", 0xC74969);

and this is the button case

case 11:
            WinToggle = !WinToggle;
            break;

hope someone can help me with this as ive been trying many tutorials and many ways with no luck for 2 days now but cant find a way to make this work. i found some that say this but where would i hook into the update or simulation function

void (*old_WinMatch)(void *instance);
void WinMatch(void *instance)
{
    if(instance != NULL && WinToggle)
    {
        old_WinMatch(instance);
    }
    old_WinMatch(instance);
}
MsHookFunction((void*)getAbsoluteAddress(targetLibName, 0xC74969), (void*) WinMatch, (void**) &old_WinMatch);

thank you in advanced if you can help me with this

the way i was able to solve this to call a method is to make sure you change your targetLibName the il2cpp lib under the includes in main.cpp

#define targetLibName OBFUSCATE("libil2cpp.so")

Have these under the includes:

bool WinToggle;

void (*WinMatch)(void *instance);

void (*old_Update)(void *instance, float delta);
void Update(void *instance, float delta) {
    if(instance != NULL && WinToggle) {
        WinMatch(instance);
    }
    old_Update(instance, delta);
}

then in your "void *hack_thread(void *)" make sure your lib is loaded first and call your MSHook then add your method you want to call

do {
    sleep(1);
} while (!isLibraryLoaded(targetLibName));

MSHookFunction((void*)getAbsoluteAddress(targetLibName, OFFSET), (void*)Update, (void **)&old_Update);

WinMatch= (void (*)(void *))getAbsoluteAddress(targetLibName, OFFSET);

under your features put a toggle

OBFUSCATE("101_Toggle_Auto Win Game"),

then make a case for that toggle under "switch (featNum)"

case 101:
    WinToggle = boolean;
    break;

you have to set = boolean; at the end or it wont work

if you have any questions PM me

@Parxdy how can I hook a void offset through hooking in an lgl mod menu for android? (private void) I have an iphone but I'm attempting for an android. the offset is 0xD45BC0. I was using a mod menu by nepmods that originally that had me just type in the offset and an update offset under a hook void offset setting. I was using an update that updated a class for stats. That update offset was 0x95F740C. is there a way to still update the void offset with that class update offset? And possibly place it into the menu itself.. I'd be grateful for a solution,
This is how I put it into the menu, but it didn't work.
I've also tried 1 and 0 instead of true and false, but that didn't work either.
I've looked all over google and YouTube but I cannot find anything.
thanks!

Sir what did you mean by you have set = boolean; at the end or it won't work. Did you are trying to say we should not set boolean at end in case..........

@Parxdy please help us, I've been this for 3 days, the off switch is not working, if i turn on once and it's turned on forever
