你好，非常感谢你们分享的信息和解决方法！

> In the “Stop Snapshot” command instrument, I did such setup. But when I hit the stop button, the Battle BGM instance stuck in the Stopping state. I looked up related topic in the forum. It is said that, if we uses stopping condition, Fmod will not really stop the event instance and left it to developers.

Event Condition 确实就像你们讨论的那样，如果在 Command Instrument 里设置了“Event Condition”为“Stopping”，并且Event仍处于“Stopping”状态，这通常是因为Event正在等待所有设置的结束条件（如淡出等）完成。如果这些条件没有正确设置或执行，事件就会持续处于“Stopping”状态，直到所有条件得到满足。

除了上面你们提到的方法外，你也可以考虑在相关Bus的Fader上添加Automation，对Parameter应用Seek Speed。这样可以在不需要编程的情况下达到渐入渐出，平滑过渡的效果。详细的流程我在这篇帖子里发过，如果你感兴趣的话可以看一下： [setMuteFadeSpeed for FMOD Studio? - #2 by li\_fmod](https://qa.fmod.com/t/setmutefadespeed-for-fmod-studio/22198/2)
