Processing input events with LuaSDL
LuaSDL offers a form of platform-independent abstraction layer to these devices with an inner event pool. You only have to query the event pool for unprocessed events and, if there are any, check for the event type.
Getting ready
Before doing any event processing, your application must initialize internal event pools. This can be achieved with the SDL.SDL_Init function, where the only parameter is a bitmask representing which parts of LuaSDL you want to initialize. You can use the bitlib library for the Lua language. Another option would be to use the bit32 internal library if you are using the newer version of the Lua interpreter. The default value here is SDL.SDL_INIT_EVERYTHING, which is fine as it starts the event pool automatically. Specifically, you can use the SDL.SDL_INIT_EVENTTHREAD or SDL.SDL_INIT_VIDEO values to initialize the event pool.
A code sample can be used to initialize the LuaSDL library. It should be used right at the start of the application...
