The queen always takes color and the board is always viewed form White's perspective, so the files go "a, b, c, d...", but here it is flipped so you have the ranks where the files should be.
The gearbox is most definitely the weakest part here. I found if you use Legacymode = 1 axles for the gears it slips a lot and has vibration issues at high speed. If you use Legacymode = 0 it gets rid of both issues but the hinges stretch a lot under large amounts of force, so the gears need to be really heavy (like 300 - 1000 density most of the time. you could probably get away with lower density here because this is a light vehicle )
Now I know this isn't yr gearbox, and you should start making your own because one gearbox won't work with every car out there
or just take the light squares and color them black and vice versa
Also the king and queen are on the opposite (wrong) sides so if you tried to use any opening that frees up the d-file, you couldn't because if White has already moved his d-pawn off its starting cell and captured something, you couldn't then take anything with your d-pawn because it would be pinned by White's queen (trust me, this pawn is useful! )
It's still a great remake of the game though. There's a donut place in my town which has the original '76 version, and somebody with far too many quarters maxed the score at 9999.
Again with the engine not being able to spin fast enough. You could get more power if you just built the engine so it gave maximum power at lower speed!
Nice one. It kind of looks like my Renault. Almost exactly. WAIT, IT'S A COPY!
Overall, nice job. There are a few issues, like sometimes the cargo will glitch through the trunk and fall out and I was also able to get some pretty ridiculous airtime on that course.
