This function returns the current velocity along the x axis for the given audio emitter.
|emitter||The index of the emitter to use.|
if audio_emitter_get_vx(emitter_player) != 0
audio_emitter_velocity(emitter_player, 0, 0, 0);
The above code checks the current x velocity of a given emitter and if it is not equal to 0, it is set to 0.
