var screen = 0; //To add a sound effect you can use addSound("file.mp3"); They work a bit like createObjectPic's and your other characters They can start, stop, pause, setVolume To use them, you must declare them (var) and when you want to play them refer to your sound var and tell it waht to do. Example: var sweetBeatZ = addSound("GuzyInDaH0us.mp3"); sweetBeatZ.play(); sweetBeatZ.stop(); sweetBeatZ.setVolume(0.5); //Makes it half volume! sweetBeatZ.pause(); var rivet = addSound("rivets.mp3"); var rivetBeatZ = addSound("popSong.mp3"); function setup(){ rivetBeatZ.play(); } function engine() { //Main menu screen if (screen==0) { } if(screen == 1) { if(clippy.collideObject(myFace)) { rivet.play(); rivetBeatZ.stop(); } } }
