hi, i am VERY confused right now. I've been trying to recreate slot cars in tic, but the checkpoint style race code I've tried will result in the car overshooting the checkpoint that tells it to go to the next spot, and stopping right below the checkpoint by one or more pixel, UNLESS the speed its traveling at is a number you would get by continuing this sequence:0.5,1,2,4,8,16. I am attempting to make it so that when you press [z] then it makes the car go faster, but if you let go, it slowly decreases. also, the locP1={...} are the locations of the checkpoints that tell it to go to the next. point is the variable that tells it which one to be going towards. if you need the tic file, just ask. if you are confused by this description, just please look at the code.

ALSO, I WOULD PREFER TO HAVE ANY HELP BE MODS OF THE CODE, BECAUSE MOST OF LUA IS CONFUSING FOR ME, AND ITS HARD TO LOOK AT EXAMPLES AND FIGURE OUT WHAT THEY ARE SAYING.
