Working with Lua arrays

Yes – a Lua table with only integer keys is called an array or a sequence. In script.lua, add the following array:

seq = { 0, 0, 0 }

From the C++ side, compared with string keys, the only difference is the data type of the keys. It’s straightforward to overload the getTable and setTable functions by using integer keys. In LuaExecutor.h, add the following declarations:

class LuaExecutor
{
public:
    LuaValue getTable(const std::string &table,
                      int index);
    void setTable(const std::string &table,
                  int index,
                  const LuaValue &value);
};

index...
