I am new to greenfoot, and trying to make a sound sustain while key is pressed. *context* Making a Piano where I can hold a key to sustain sound. (right now all it does it just play a short sound when I press) So far what I can only think of is: make an if statement where: -If a Key is pressed and held for <1 second, loop play a sound. (or play a separate version of the sound, and maybe "if key is not pressed", Stop playing sound (dont know if its possible, maybe with sound.stop ()) The issue is I don't know if there's a way I can track time, and it would cause the sound to not "sustain" but just loop play. If I used a different modified audio file, it would work, but only for as long as the file plays the audio. So If I held the key for 2 seconds, and the audio was 3 seconds, it Would work but still play for the remaining 1 second even if the key is not pressed. The same applies if I hold longer than the audio clip lasts, it just ends there. So basically I am asking: -How can I make so I can record time? (so I can make so if keypressed is <1second, play sustain sound. -Is it possible to even sustain a sound (or do I have to use a separate file and just mistime it)
