# Registering object methods

Class methods are registered with the RegisterObjectMethod call.

    // Register a class method
    void MyClass::ClassMethod()
    {
      // Do something
    }

    r = engine->RegisterObjectMethod("mytype", "void ClassMethod()", asMETHOD(MyClass,ClassMethod), asCALL_THISCALL); assert( r >= 0 );

It is also possible to register a global function that takes a pointer to the object as a class method. This can be used to extend the functionality of a class when accessed via AngelScript, without actually changing the C++ implementation of the class.

    // Register a global function as an object method
    void MyClass_MethodWrapper(MyClass *obj)
    {
      // Access the object
      obj->DoSomething();
    }

    r = engine->RegisterObjectMethod("mytype", "void MethodWrapper()", asFUNCTION(MyClass_MethodWrapper), asCALL_CDECL_OBJLAST); assert( r >= 0 );
