在编写小甲鱼的飞机大战时出现的BUG

完全照抄小甲鱼的飞机大战代码，目前处于刚完成碰撞检测部分，但是存在BUG，即当我方小飞机碰撞到敌方小飞机时，敌方非碰撞到的正常飞行的小飞机突然消失了，求大神指点

附带代码：

另外补充：该BUG也存在于我方飞机与敌方小飞机并未发生任何碰撞时，敌方小飞机消失

西瓜味的苹果 发表于 2020-11-26 17:08:13

建议你将其他辅助功能代码去掉，然后留下我方飞机，地方飞机，在代码减少的情况下，很容易就发现bug

我试了一下，如果只是留双方飞机情况下，并没有出现BUG。但是如果加上又找不出哪里出问题

shzy66 发表于 2020-11-27 22:42:56

今天在编这个游戏时，发现如果我方飞机碰到敌方飞机之后处于重复我方飞机阵亡的图片过程，敌方飞机就会出现突然消失的BUG，而如果我方飞机一直存活，则没有该BUG出现

西瓜味的苹果 发表于 2020-11-30 10:08:19

好的，等下，我看看代码

我看代码没有问题，感觉还是缩进的问题，我给你发了可以运行的飞机大战，你对照看看

西瓜味的苹果 发表于 2020-11-30 10:25:03

如果还有问题，联系我qq：3434394197，当初我也是像你一样来这求助的，哈哈
