Help! Edit Hex code specific

[UnrealSkill]

I need to edit a specific function in HEX for mod 2lcpp.
but in the conventional way it crashes because I think I'm editing it wrong, what's the correct way to edit the area below:

ORIGINAL CODE HEX

if I edit by putting the value "F0 41 2D E9 40 D0 4D E2" to "01 0A A0 E3 1E FF 2F E1" = 1000 the game crashes then what is the correct way to edit a function that does not return in INT format but in your parameter?

Patching in param you need to open IDA, you cant simply blxr without see the structure of the whole code

could you give me an example?

You need to use hook here not hex

 

[Poison Modz]

bool AddCoin = false;

void (*old_addcoin)(void *instance, int coin);
void addcoin(void *instance, int coin) {
if (instance != NULL) {
if (AddCoin) {
old_addcoin(instance, 1000000);
return;
}
}
old_addcoin(instance, coin);
}

MSHookFunction((void *)getAbsoluteAddress("libil2cpp.so", 0x5E5BD4), (void *) addcoin, (void **) &old_addcoin);

OBFUSCATE("0_Toggle_Add Coins"),

case 0:
AddCoin = boolean;
break;

void addcoin(void *instance, int coin) {
if (instance != NULL) {
if (AddCoin) {
old_addcoin(instance, 1000000);
return;
}
}
old_addcoin(instance, coin);
}

MSHookFunction((void *)getAbsoluteAddress("libil2cpp.so", 0x5E5BD4), (void *) addcoin, (void **) &old_addcoin);

OBFUSCATE("0_Toggle_Add Coins"),

case 0:
AddCoin = boolean;
break;

thanks for the immense help, although I still don't know how to use the hook, I think that from here I can go alone and learn thanks for the help friends

Don't use dnspy address ok
Use only address dump.cs

Don't use dnspy address ok
Use only address dump.cs

is there a different thing between dnspy and dump.cs?

is there a different thing between dnspy and dump.cs?

No, there isn't any difference when it comes to offsets the same offsets you'll see in dump.cs file will be same in dnspy, in fact looking and searching in dnspy is even better since it give better structural view, the only time you might want to check dump.cs is if there isn't a dummy dlls
