高分悬赏，在线等，请指教
这是游戏贪食蛇的游戏代码，我不知道为什么运行后只显示一个JFRAME的框，画布还有蛇什么的都没有显示，代码语法上没错，不知道逻辑上哪错了，请指点，在线等，解决就给分

你这个我会仔细看看，不过这是我辛苦写的算法呀，不知道哪错了，不白写了嘛，我想知道哪不对，跪求了，剩这100都给你们了Top

帮你顶一下！慢慢分析！如果有地方是你不敢肯定正确的地方容易出错！Top
5 楼gtlang78（）回复于 2006-10-05 16:28:25 得分 0
run() 方法里的循环
while (running)
{
...
}
没有把 moveOn() 和 es.repaint()包进来.Top

我已经改了，可是改完之后怎么一运行就出现你已经失败的的对话框呢，请高手再给指导一下行么，因为我没分了，所以一起把这个问题问完吧Top
