Working with Lua table functions

For our Lua executor, we want to call table functions with the same level of support as calling global functions. Similar to call and vcall, we can define two functions named tcall and vtcall that call table functions and return a single value and a list of values respectively.

We need to add two more pieces of information to the new C++ member functions – namely, the following:

• The table name, which is obvious
• Whether we should pass the self argument to the table function

More on the latter point:

• When the table function does not refer self and is used like C++ static member functions, we do not need to pass self
• When the table function refers self and is used like C++ member functions, we need to pass self

Let’s implement the code to reinforce what we have just talked about.

Implementing table function support

In LuaExecutor.h, add the following declarations:

class LuaExecutor
{
public...
