I don't think its really a bug. The attraction for objects is calculated to the center of the object. Even though it is a ring, objects are still attracted to the center of it. Also it was something like 180 kg, thats why the little square was effected so much in the middle.
Geometry?!? Just kidding. Technically the 30-60-90 triangle is also a right triangle, and the equilateral triangle is also an isoceles triangle. Wow. Four triangles in one sentence.
Sometimes when "enter" is assigned on one computer, it doesn't work on another computer. Like this scene for me. Normally I just re-assign the "enter" commands to my "enter", and the scene works fine, but this is too complicated for me to tinker with. If you could, please tell me where I need to change the "enter" at, or possibly change the command in another version. Thanks.
Edit: Nevermind, it was the thyme commands that need to put in like you said.
What are you talking about minyman? I'm pretty sure the only thing the main wheel is colliding with is the orange circle and the plane. That's a crazy motor Revilo314.
