Help! Field offset hooking with switch

[TimidNova]

so here's my hook

void (*old_isPremium)(void *instance);
void isPremium(void *instance) {
instanceBtn = instance;
if (instance != NULL) {
if (Premium) {
*(bool *) ((uint32_t) instance + 0x320) = true;

}
}
return old_isPremium(instance);
}

HOOK_LIB("libil2cpp.so", "0x156C100", isPremium, old_isPremium);

and then my switch case

case 5:
Premium = boolean;
break;

would this be the correct way to make it modify the value when the switch is on and then return when off?

 

[TimidNova]

Also can I use the Awake function instead of Update function if my class doesn't have it?

 

[TimidNova]

Also If I use an Update function outside of the class how exactly would that work? Would I have to do anything special

Your everything is right but just remove your
instanceBtn = instance; from that like this

void (*old_isPremium)(void *instance);
void isPremium(void *instance) {
if (instance != NULL) {
if (Premium) {
*(bool *) ((uint32_t) instance + 0x320) = true;

}
}
return old_isPremium(instance);
}

And try to use
This MSHookFunction((void*)getAbsoluteAddress("libil2cpp.so", 0x156C100), (void*)isPremium, (void**)&old_isPremium);

in the place of
HOOK_LIB("libil2cpp.so", "0x156C100", isPremium, old_isPremium);


And
Make sour your Switch will like this

OBFUSCATE("5_Toggle_Premium Unlock"),

And the case like this

Case 5:
Premium = boolean;
break;

Now you will not get any kind of problem

then it's all about the instance, if you can get the instance of the field from another class then of course you can, here are some examples:

Simple.

void (*old_isPremium)(void *instance);
void isPremium(void *instance) {
instanceBtn = instance;
if (instance != NULL) {

if (Premium) {
*(bool *) ((uint32_t) instance + 0x320) = Premium;

}
}
return old_isPremium(instance);
}

HOOK_LIB("libil2cpp.so", "0x156C100", isPremium, old_isPremium);
