# Implementing GM Without Collisions in Metin2

This guide outlines the steps to implement a system allowing Game Masters (GMs) to move without collision detection in Metin2.

## 1. Modify `Locale_inc.h`

Add the following define:

```cpp
#define ENABLE_GM_WITHOUT_COLLISIONS
```

## 2. Update `ActorInstanceCollisionDetection.cpp`

Replace the following functions with their updated versions:

### `CActorInstance::AvoidObject`

```cpp
bool CActorInstance::AvoidObject(const CGraphicObjectInstance& c_rkBGObj)
{
#ifdef ENABLE_GM_WITHOUT_COLLISIONS
if (IAbstractPlayer::GetSingleton().IsGameMasterInstance(GetVirtualID())) {
return false;
}
#endif
#ifdef __MOVIE_MODE__
if (IsMovieMode())
return false;
#endif
if (this == &c_rkBGObj)
return false;
if (!__TestObjectCollision(&c_rkBGObj))
return false;
__AdjustCollisionMovement(&c_rkBGObj);
return true;
}
```

### `CActorInstance::IsBlockObject`

```cpp
bool CActorInstance::IsBlockObject(const CGraphicObjectInstance& c_rkBGObj)
{
#ifdef ENABLE_GM_WITHOUT_COLLISIONS
if (IAbstractPlayer::GetSingleton().IsGameMasterInstance(GetVirtualID())) {
return false;
}
#endif
if (this == &c_rkBGObj)
return false;
if (!__TestObjectCollision(&c_rkBGObj))
return false;
return true;
}
```

### `CActorInstance::CanSkipCollision`

```cpp
bool CActorInstance::CanSkipCollision()
{
#ifdef ENABLE_GM_WITHOUT_COLLISIONS
if (IAbstractPlayer::GetSingleton().IsGameMasterInstance(GetVirtualID())) {
return true;
}
#endif
return m_canSkipCollision;
}
```

## 3. Modify `AbstractPlayer.h`

Add the following method declaration:

```cpp
#ifdef ENABLE_GM_WITHOUT_COLLISIONS
virtual bool IsGameMasterInstance(DWORD dwVID) = 0;
#endif
```

## 4. Update `PythonPlayer.h`

Add the following method declaration:

```cpp
#ifdef ENABLE_GM_WITHOUT_COLLISIONS
bool IsGameMasterInstance(DWORD dwVID);
#endif
```

## 5. Update `PythonPlayer.cpp`

Add the following method implementation:

```cpp
#ifdef ENABLE_GM_WITHOUT_COLLISIONS
bool CPythonPlayer::IsGameMasterInstance(DWORD dwVID)
{
CInstanceBase* pTargetInstance = CPythonCharacterManager::Instance().GetInstancePtr(dwVID);
if (!pTargetInstance)
return false;
return pTargetInstance->IsGameMaster();
}
#endif
```

These changes will implement a system allowing GMs to move without collision detection in Metin2.
