我有以下代码，它适用于类似于太空入侵者的基本自上而下射击游戏。当玩家的子弹击中敌人时，敌人会正确地跟随各种命中功能并在三分之一秒内闪烁不可见。然而，当玩家被击中时，尽管使用了相同的功能，他似乎永久地变成了隐形。关于为什么会发生这种情况以及我哪里出错的任何想法？我的代码可能会被那些有经验的人认为是混乱的，所以请尽可能多地批评：P代码背后的结构和过程在我的脑海中是有意义的，但如果有人在努力，请随意问“wtf是你吗？做“：P

答案 0 :(得分：0)
很可能你的问题来自你用于所有事情的单个布尔值lossHealth。该布尔值只能有2个值，但是你可以将它用于所有敌人和玩家。单个布尔值不可能跟踪所有敌人和玩家状态。你应该拥有的是每个敌人和玩家的一个布尔值。
