Algodoo

works good, drove a train over it and nothing broke, but i did have to add a ramp at the other end. 8/10

unfortuntely, i could not get the engine to power it, so i had to put a motor on a drivecircle.

i added wheels to make it roll, but it kept bouncing around

there's nothing there.

had to loosen them

set it by rotating the indicators while the sim is paused

i deleted all the deoxyses boxes except 1, then used generate geometry to texture.

the first 3 balls are pretty accurate, the 4th is a bit off, and the others IDK.

i thickened the walls and made it a spring engine and got it to reach 30 m/s before it glitched out

i find the systems (especially the menu) absolutely amazing.

the dyno refuses to stop, even when i put several axles on it to lock it.

It probably wasn't originally intended to fly, but it does so very well.

The thrusters seem to be misconfigured. They shouldn't cause flexing of structural elements.
