Summary

Lua's capabilities should be fairly clear at this point, and SDL has been tackled for the second time in this book. Here are a few important points before continuing to the next chapter:

• Blitting is still the key to rendering objects in SDL, whether using Python or Lua.

• Rects are still the key for blitting a sprite or object to the screen.

• The key to utilizing the c API is the stack.

• Tables in lua are used everywhere. They make good containers for game objects and good containers for global variables in the c API.

• The most commonly found API function (after lua_state and lua_open) is lua_dostring.

• The lua API functions are held within the lua.hheader, which must be wrapped in a c extern command.
