Questions about Keystates and Events

SDL Development
1

Hi,
Im an SDL beginner and I have a few questions…

  • I would like to know when it is prefered to use keystates over events.

  • If I don’t poll the SDLEvents, will it bloat the memory?

  • Also, I dont get how events should work. With SDL I need one part of the program to take care of all events, is that true?

Thanks.

  1. If you are just after keyboard information, getting the keystate is much
    faster than SDL_PollEvent(). If you want all the information (application
    state, mouse movement, key presses, etc), SDL_PollEvent() is the optimal way
    to go.

  2. No

  3. No, you can use SDL_PollEvent() multiple times per loop in different
    functions (although this is really slow!). The examples demonstrate how to
    use SDL events (polling and otherwise) - it’s usually all in one place to
    make it easier to follow. Don’t be afraid to experiment.

Take care,
