# Play the looping sound. 
# Wait until the sound is finished before taking off.
controller.sound.play(LOOPING)
while controller.sound.is_active():
    wait(50, MSEC)
drone.take_off(climb_to=500)
wait(1, SECONDS)
drone.land()

play_file#

play_file plays a custom sound loaded by the user at a specified volume percentage. Since this is a non-waiting method, the drone plays the custom sound and moves to the next command without waiting for it to finish.

用法：

controller.sound.play_file(file, volume)

范围

描述

file

One of the custom sound files uploaded by the user, from SOUND1 to SOUND10. The sound number aligns with the number shown in the AIR Control Panel.

volume

可选。音量，取值范围为 0% 到 100% 之间的整数。默认值为 50%。

 
# Upload a sound file in VEXcode.
# Play the custom sound.
controller.sound.play_file(SOUND1)


# Upload a sound file in VEXcode.
# Play the custom sound at full volume.
controller.sound.play_file(SOUND1, 100)


# Play the custom sound sound. 
# Wait until the sound is finished before taking off.
controller.sound.play_file(SOUND1)
while controller.sound.is_active():
    wait(50, MSEC)
drone.take_off(climb_to=500)
wait(1, SECONDS)
drone.land()

play_note#

play_note plays a specific note for a specific duration. Since this is a non-waiting method, the drone plays the specific note and moves to the next command without waiting for it to finish.

用法：

controller.sound.play_note(note, duration, volume)

# Play C5 for 2 seconds
controller.sound.play_note("C5", 2000)


# Play C5 for 2 seconds at full volume
controller.sound.play_note("C5", 2000, 100)


# Play a short tune.
controller.sound.play_note("C5", 1000)
while controller.sound.is_active():
    wait(50, MSEC)
controller.sound.play_note("D5", 1000)
while controller.sound.is_active():
    wait(50, MSEC)
controller.sound.play_note("E5", 250)
while controller.sound.is_active():
