基础知识：enum Life is but a span.

enum spriteZ
    {
        kZForMap = 0,
        kZForPlayers,
        kZForHP,
        kZForLabel,
        kZForDownMenu,
        kZForJoyStick,
        kZForMyBulletsBase = 100        
        kZForMyBulletsBase1
    }; 代表从0,1,2,3,4,5,100，而不是从0到100等值排列 如果输出kZForMyBulletsBase1，则显示101
