Help! How To Hook Field List Offset

[imls01245]

public int[] statUpgradeCost; // 0x90

I was searching a Hook using MonoArray in Field But I can't find one, please help me!

Here is The Struct I found in Numark Tutorial but i dont know how to use it

template <typename T>
struct monoArray
{
    void* klass;
    void* monitor;
    void* bounds;
    int   max_length;
    void* vector [1];
    int getLength()
    {
        return max_length;
    }
    T getPointer()
    {
        return (T)vector;
    }
};

You get that array like this:

monoArray<int> *statUpgradeCost = *(monoArray<int>**)((uint64_t)your_instance+ 0x90);

Depending on what type of array it is, you'll put the type inside the <> brakets. Here it's int, can also be <float>, or <void**> if it's an array of class objects.

Sorry i'm new to this type of hook but it says error: in statCost = 0; subscripted value is not array , pointer or vector

Reference: How to hook Array?

monoArray<int> *statUpgradeCost = *(monoArray<int>**)((uint64_t) instance + 0x90);
            
for (int i = 0; i < statUpgradeCost->getLength(); i++) {
   auto statCost = statUpgradeCost->getPointer();
   statCost[i] = 0;
}

Problem solved now

monoArray<int> *statUpgradeCost = *(monoArray<int>**)((uint64_t)your_instance+ 0x90);

Thank you bro, @Tosilegit

   statCost[i] = 0;
}

Just cast it to int and now you're good to go:

 auto statCost = (int*) statUpgradeCost->getPointer();

Oh right, I'm used to using a struct that doesn't need that. I also think that the cast should be (int)?

Anyway, no problem.

Bro @Tosilegit You know How to Hook this?

public Boards[] boards; // 0x54

Bro @Tosilegit You know How to Hook this?

public Boards[] boards; // 0x54

Can you show what "Boards" is exactly? From dump or dll

It is a struct

public struct Boards // TypeDefIndex: 4262
{
 // Fields
 public string description; // 0x0
 public string boardTex; // 0x4
 public int coinCost; // 0x8
 public int sodaCost; // 0xC
 public bool isAvailableToPlayers; // 0x10
 public PerkType perkType; // 0x14
 public float perkAmount; // 0x18
}
