python打飞机游戏的一个小问题
在aline_invasion.py的while循环里面需要先运行gf.check_events(ship)后再运行ship.update()，check_event(ship)这个函数里面的for循环不断接受我键盘按下的命令，在for循环运行的时候gf.check_events(ship)还没执行完，所以while循环里面的ship.update()是没有执行的，所以飞船位置在我连续发出某一指令的时候不是不会动吗？可实际上飞船还是动了，而且是连续移动，这是为什么呢？当我把ship.update()放到check_events(ship)的for循环里面之后发现飞船不能连续移动，这又是为什么？aline_invasion.py

我就先不回答问题，我就看这颜色就心疼你这发帖发了多久啊 陈尚涵 发表于 2020-8-6 17:08
