Bouncing Balls with Soundcolors is a much enlarged version of: (link to project) by Canthiar You now have colors an sounds and many parameters to play with: Up / Down = -/+ Gravity Left / Right = -/+ Emitter Speed B / A = -/+ more Balls 1 = switch Edges 2 = switch Turn Effect 3 = switch Random 4 = switch Drawing 5 = switch Sound Space = start Balls again DragDrop Collision Objects DragDrop Balls DragDrop Emitter Turn Emitter by pulling it's tip H = Help (english) G = Help (german) Chantiers original description: You can move the object emitter around with the mouse and change the direction by clicking on the pointed end. This is what I consider a production version since I've inlined a few things. I have a more academic version that is a little easier to read. The whole thing is also dumbed down a little to make the math a little easier. How it works: When a ball encounters a collision object it uses the [ point towards[ Collision ] ] command block and then uses sin and cos to calculate a colliion normal. That normal is used to calculate a resulting velocity perpendicular to the surface and velocity tangent to the surface. Friction and restitution are applied to make the ball bounce.

Wow *__* Dieses Projekt ist genial. Die Schwerkraft funktioniert echt toll, die Bälle hüpfen perfekte Parabeln =O Ich find das toll, wie die Malstifthelligkeit und -dicke sich mit der Ballhöhe verändert. Daumen hoch =D
ja...aber ich hatte auch eine gute Vorlage ;-) ((link to project) ...damals gab es noch keine RemixFunktion...
*mir meine ich xD
Love&Fav, den Code muss ich mich umbedingt näher ansehen =)
Amazing!
thanks for commenting :-)
This is fantastic. I love that there are so many different ways to change what the balls do.
Happy you like it. Yes, it took some time and many relaunches to have so many options. But I think it was worth doing it, as it was choosen to go into the Scratch Distribution as example for a complex Project. And: It's a remix of an other great project (link to project) ...you are greater if you stand on the shoulder of giants like Canthiar ;-)
Very cool
wow

Cool!
nice
Your work with Canthiar is a great model of collaboration!
WOW!
How do you link on a comment??
COOL!!!
I solved the problem with help of John and Canthiar: Now Offline+Online work the same. There are some sphisticated bugs in the Java-Player (e.g. with the "touched"-block) I had to work around. See our discussion at: (link to forums)
Wonderful project! I just saw your forum post about the new issue that has arisen. We will look into it!
There seems to be a new Version of the Online-player (Java-Player) that causes the balls getting "caught" by the collision objects. That does not happen in the Offline-player (Squeak-Player). It also worked in an former version of the Online-Player. I hope the Scratch-Team will fix it soon.
brilliant
spooky
wow
mazing
cool
Those are some wild changes.
Spooky !
