Well, I know I said I wouldn't make another project, and I would have made this in python, but I was on a Chromebook and had to make it in scratch. It is too awesome not to share! A node is a point where it calculates it's position relative to others. The more there are, the slower the program will be.
All scripts by me. Updates: v1.0: - I shared the project as a string simulator. v2.0 - I made it into a fluid simulator v2.1 - I added the lag control. v3.0 - I completely changed the way the nodes calculated their position relative to other nodes. v3.1 - finally fixed the problem where nodes get stuck on the top and bottom of the screen lol
