The smoothest way I could find to do it was to duplicate the audio element for each menu item. It seems to honor the pause but then not the play in many cases. play() again, but in my testing that doesn’t help much. A single audio element can’t play it’s own sound in an overlapping way. play() a lot faster than that sound can finish playing. Greenfoot 07: Playing Sound (WJEC Computer Science) - YouTube This video demonstrates how to add sound to the collision detection with actors in Greenfoot 2.4.2. Immediately this uncovered a problem: you can hover over menu items triggering a. My original idea for playing with this was a navigation menu that played a little clicking sound while hovering over them. They do it by injecting a new audio element into the DOM everytime that yeti dude is hovered: $("#speak").mouseenter(function()) Trials and Troubles: Overlapping Sounds The teaser page for the Goodfoot mobile app uses a similar technique to play weird groaning noises (via Dave Rupert) when you hover over the yeti dude. So to make this sound begin to play when the mouse hovers over a certain element: var audio = $("#mySoundClip") Let’s use jQuery, just because it’s going to make selecting and dealing with events easier. Var audio = document.getElementById("mySoundClip") To play the sound with JavaScript: var audio = document.getElementsByTagName("audio") declare at the top of the class static GreenfootSound electricity new GreenfootSound ('Electricity2.wav') //then, instead of aySound (. ![]() You can declare a class field to hold a GreenfootSound object so it is in memory when you need it. Again unfortunately, we can’t tell an element what to do through CSS, so we’ll need JavaScript. It may be that it takes a moment for the sound file to load. Our goal is to have the sound play when the mouse hovers over a certain element, like a menu item. If you want it to play but not be seen, make sure to use the autoplay element ( ). ![]() If you want a little player element, make sure to use the controls attribute ( ). If you insert the code exactly as above into a page, you won’t see or hear anything. Your browser isn't invited for super fun audio time. To get as much browser support as we can, we’ll do it like this with both an MP3 source (WebKit and IE) and an OGG source (Firefox and Opera). Is greenfoot already using the Line returned by Audiosystem Can anyone recommend a reliable solution Im on OS X 10.6.8. The timing is incredibly wonky and sometimes sounds dont trigger at all. But nobody around here wants to deal with Flash right? So let’s do it with HTML5, which can play sound through its element (Firefox 3.5+, Chrome 3+, Opera 10.5+, Safari 4+, IE 9+). 2 Hi all, Im having issues getting Greenfoot to reliably play back sounds. To play sounds when the mouse goes over a certain area, we’re going to need to rely on HTML5 or Flash. I’d argue that sounds are part of design and thus the ability to play/trigger it belongs in CSS, but alas, we’re not there yet. Some stuff about play-during and cue-before and stuff that looks promising but really it’s for aural stylesheets (accessibility / screen reader stuff) not just how to make donkey grunts when you roll over a menu item in any ol’ browser.Some stuff about Counter Strike: Source. ![]() When you google around for how to play a sound with CSS, you’ll find:
