Gravity simulation

I finally managed to finish the complete guide for users. I added a step-back button so everyone can return to the guide if they missed something. I also added a menu for giving speeds right from the start. It means that the simulations won’t neccesarily be from stable positions. -> I hope I don’t need to mention the bug fixes everyone knows about :

I recently made a huge jump with the gravity simulator. I added a third body to interact with and I also added kind of a huge guide for the users. The most annoying thing to do was the debugging part. It’s always hard to find the roots of the problem. I hope this simulator ’ll get as much stardust as it can because I´m working hard to get the results I want.

I’m working on simulation between bodies in space. Today, I finally figured out how to do it for the first time. Months before I struggled to perform such a difficult physics simulation. I didn’t really ever understand how dx and dy works. So I tried it and it works pretty well even in scratch.
