Small progress on Shura's Motoadventures. I think I finally found simulation parameters that I'm happy with. It turned out that the bounciness of the rear wheel was due to a setting in the simulation called constraintIterations which I had to set to a higher number. Remember to read the docs if you're using a new library.
These are some random assets I found at
opengameart.org, I haven't decided what art assets I'm going to use but I wanted to see how it would look. I'm doing really dumb shit here where I'm "drawing" tiles for every single block even if it's not in view of the camera and even then I'm still getting a steady 30fps.
