[解决办法]
暂停功能最好完善下.
我是指来了电话或短信时的中断和恢复游戏.
你的代码
public void startApp() {
gameworld.start();
display.setCurrent(gameworld);
}
public void pauseApp() {
}
意味着,电话呼入中断游戏后,不做任何事情.gameworld这个线程继续工作.
看看在pauseApp()中加入gameworld.sleep(long millis);或者加入自己写的暂停游戏方法.
而恢复游戏后.程序再次调有一次startApp()中的gameworld.start();
游戏会不会出逻辑错误?
我没细看完呢,只是先说下我个人的看法.一点小建议.
你的这个没注释,不好看啊.
让大家帮你提修改意见,再多加些注释会更好.
