It should be enough for simple games. If you go to this link http://www.wiley.com/WileyCDA/WileyTitle/productCd-0470068221,descCd-DOWNLOAD.html <http://www.wiley.com/WileyCDA/WileyTitle/productCd-0470068221,descCd-DOWNLOAD.html>you can download all the code for the book, and you'll see that the simple games just use these techniques. (I'm not recommending the book, just pointing out a source of code for simple 2D games.)
P.S. Your English is not perfect, but quite understandable; keep up the good work.
