Calling a function in a table from C++ without loosing 'self'

["Framework Studios: Hugo" <hugo@...>]

Hi all,

 

I'm trying to call a function called 'init' in a table from C++. Currently this is what I've got:

 

int cGameObject::start(lua_State *VM)

{

// first get the table

 lua_pushstring(VM, m_TableName);        // m_TableName = "GameObject" in this example
 lua_gettable(VM, LUA_GLOBALSINDEX);

// get the 'init' function from the table

 lua_pushstring(VM, "init");
 lua_gettable(VM, -2);

// call the function

 lua_call(VM, 0, 0);

 

return 0;
}

 

Now this works fine, except when using 'self' in the init function, it fails. 'self' is unknown.

 

But when I do this: lua_dostring("GameObject:init()") 'self' *is* known in the init() function.

 

The reason why I would like to do the call myself, besides performance, is I want to pass any parameters passed to the 'start' function on to the 'init' function.

 

So, what am I doing wrong? Why is 'self' unknown when calling the 'init' function directly?

 

    Thanks,
