Oh, how many times have I wished for a pointer to just null itself.
This one, depending upon how it gets implemented, should be a really good one.

Well, there is one that will imply you can only develop using anything that you have bootstrapped yourself, using hardware that you have designed and manufactured yourself, using tools that you have designed and manufactured yourself, using tools that you have designed and manufactured yourself …

… with your own bare hands.

Nice. Now just if you could make it more physics’y. As in, make it go faster when it falls downwards and make it look like it is putting in extra effort, in cases it is going upwards, higher than what momentum would take it.

If you feel like doing this, I’d suggest using parameters for:

• gravity
• momentum
• friction, so just reduce momentum based on traveled distance
• minimum speed, to make sure it keeps going and that will look like it is using its motors to keep running
