AudioSource.isPlaying

Description

Returns whether the AudioSource is currently playing a clip (Read Only).

AudioSource.isPlaying returns true if the AudioSource is playing any clip. This includes if you use PlayOneShot() or if you play a video or timeline track through the AudioSource.

Note: AudioSource.isPlaying returns false when AudioSource.Pause() is called. If you use AudioSource.Play() back again, it returns true.

Note: If you use AudioSource.PlayDelayed to play your clip, AudioSource.isPlaying returns true during the delay.

// When the audio component has stopped playing, play otherClip.
// Remember to assign an AudioClip in the Inspector.
