This action can be used to stop a sound from playing. You select the sound from the asset explorer and all instances of that sound will stop playing (so if you have set the same sound to play in three different events then all of them will stop).
Argument Description Sound The sound resource to stop
The above action block code checks for a mouse button press and if one is detected it then checks a global variable to see if it is not true. If it is not true, then a sound is played (and looped) and the global variable set to true, otherwise the sound is stopped and the global variable is set to false.
