As time ticks away, the game I developed acts in slow motion...
I'll show my sample source code.
I included SneakyInput downloaded from there.
http://mac.softpedia.com/get/Developer-Tools/SneakyInput.shtml
Additional to sprite is too troublesome so that I created createAnime method.
But, It erases number of memory.
