这个怎么不放个音乐在里面，不就更清楚了
这个变量，
playing = false
相当于 aud.paused 红影 发表于 2024-6-26 19:51

这个变量，
playing = false
嗯，实际已经把控制语句加好了。 这是代码实现的运动之美{:4_199:} 点击之后跟弹簧似的，曲线伸缩。。。
又是活的。。{:4_170:} 马黑黑 发表于 2024-6-26 20:11

用在帖子里估计也很漂亮，比如用手上捧的小花开始散开，暂停时又变回原点{:4_173:} 红影 发表于 2024-6-26 20:53

加上aud的监控语句，aud.paused 换上 playing 变量（声明变量不要）就可以了 马黑黑 发表于 2024-6-26 21:08
