# MAT dash

a simple c++ library to wrap hooks for calling conventions found in 32 bit windows gd

Note this is not a hooking library, only a template wrapper for detours and trampolines, though it does come with a minhook binding

This project is very basic, as its only temporary while [Geode](https://github.com/geode-sdk/) is in the works

## Usage

```cpp

#include 

// defines add_hook to use minhook

#include 

// lets you use mod_main

#include 

#include 

using namespace cocos2d;

class MenuLayerMod : public gd::MenuLayer {

public:

    // here the name cant be `init` as that'd make it a virtual

    // which doesnt work with the current code

    bool init_() {

        if (!matdash::orig<&MenuLayerMod::init_>(this)) return false;

        auto label = CCLabelBMFont::create("Hello world!", "bigFont.fnt");

        label->setPosition(ccp(200, 200));

        addChild(label);

        return true;

    }

};

void MenuLayer_onNewgrounds(gd::MenuLayer* self, CCObject* sender) {

    std::cout << "cool!" << std::endl;

    matdash::orig<&MenuLayer_onNewgrounds>(self, sender);

}

bool GJDropDownLayer_init(gd::GJDropDownLayer* self, const char* title, float height) {

    return matdash::orig<&GJDropDownLayer_init>(self, "my own title", height * 0.5f);

}

matdash::cc::thiscall PlayLayer_update(gd::PlayLayer* self, float dt) {

    matdash::orig<&PlayLayer_update>(self, dt * 0.5f);

    return {};

}

void PlayLayer_update_(gd::PlayLayer* self, float dt) {

    // another way of specifying the calling convention

    matdash::orig<&PlayLayer_update_, matdash::Thiscall>(self, dt * 0.5f);

}

void mod_main(HMODULE) {

    matdash::add_hook<&MenuLayerMod::init_>(gd::base + 0x1907b0);

    matdash::add_hook<&MenuLayer_onNewgrounds>(gd::base + 0x191e90);

    matdash::add_hook<&GJDropDownLayer_init>(gd::base + 0x113530);

    matdash::add_hook<&PlayLayer_update>(gd::base + 0x2029c0);

    // another way of specifying the calling convention

    matdash::add_hook<&PlayLayer_update_, matdash::Thiscall>(gd::base + 0x2029c0);

}

```
