Sorry claster2013 but I have to agree with Tire burnout. Your scene needs a lot of work before it can be classified as a game. I suggest that you spend some time playing other people's games here on Algobox. Try to figure out how their games work. Ask questions. Most people wouldn't mind if you ask them questions by leaving comments. For example, you can ask something like, "How did you make that circle move with the arrow keys?" It takes a lot of time to learn how to make things move and to behave the way you want them to behave. The more time and effort you put into learning Algodoo, the better and more impressive your scenes will become! Failure is not always a bad thing because it's almost always a learning experience which is a good thing!
Very impressive, Mr. Noonan! I am blown away by the work you (and AI) have done on this scene. This is exactly the kind of thing that I have tried to do for many years but was never able to get this kind of result. If Algodoo were to give out an "Amazing Scene" award for technical and artistic excellence in a scene, this scene of yours would win First Place!
The reason why the circle spins and accelerates without any input power from an external force (except for a slight push to get it started) is because YOU gave its "Friction" value a negative number. In real life an object's friction cannot have a value less than zero because friction always opposes motion, but a negative friction value would imply that it aids motion!
There are other parameter values (Attraction for example) that Algodoo allows the user to exceed beyond normal values that are typically found in real life objects. So, no, I hate to be the one to break the news to you but you did not discover perpetual energy gain.
I've never seen a liquid baby before but this is pretty cool! Now you maybe should consider making a whole family of liquid people (a mom, a dad, and 4 or 5 kids) and have them race against each other!
Thanks MarioBro1337... apology accepted! As I've stated in my comment: Here we've all done silly and dumb things when we were young. Most people outgrow that kind of behavior, and others.... well not so much.
