too slow ? try at tubowarp : https://turbowarp.org/1374838054 This is a cyclecomputer simulator, (calculate distance) (I know, cyclecoputer calculates distance by radius (r) if you add, but this r variable presents the radius × r)
sorry for 5th re- share, but I fixed the bugs !!! ------------------------------------------------------------------------- credits: thanks for the non-scratch person what teach me for the cycle fysics. Big credit for @sadie_is_awesome for idea using lists for draw a line.
