Crash when calling CPlaceable::GetAtDirection()

[japajoe]

The function call in this method is incorrect and causes my application to crash:

CVector CPlaceable::GetAtDirection()
{
    return ((CVector(__thiscall *)(CPlaceable *, ))0x50E420)(this);
}

Upon inspection I noticed the method takes in a float pointer as parameter, which is then assigned in the actual method. The return type is also incorrect as it still crashes because a CVector is not returned. With the following adjustments I have managed to get it to work:

CVector CPlaceable::GetAtDirection()
{
    CVector result;
    ((void(__thiscall *)(CPlaceable *, float *))0x50E420)(this, &result.x);
    return result;
}

Also, the following 2 methods suffer from the same issue:

CPlaceable::GetRightDirection()
CPlaceable::GetTopDirection()
