I dont use the arrow keys cause when i was trying different cars out, most of them used the arrow keys to drive ...you can edit them if you want but i found it annoying with the arrow keys.
Well anyway, i played with his also a while ago and i came up with an entire car just never posted it.
EDIT: Sorry it does work, algodoo just opened the file incorrectly lol
Hooray you made a few gradients of different colors and put them in boxes. Dont mean to be mean but so what. FYI the lag comes from your little symbol you have on each "neon" and their cases. Delete them and boom you just deleted about 800 geoms. No offense but fail.
i fixed myself and ran. The timing is all wack - water2 gate opens after the piston makes pressure so the water goes boom. Also, its not really a pump because the water just falls down when the gates open and the piston is not needed. turn it upside down and edit it a little and it'll be a pump. The real pump in this scene is the series of gears.
Actually i didn't see the rotors in the list since i neglected to check up on anything for a few days. Anyway I made my own rotors with some help from the forums and finished my project but was WAY too laggy and infeasible to share so I just decided not to. BTW it didn't involve the rotors having motor hinges
