Use WASD or Arrow keys to drive your car. Space for Nitro boost. "Q" to reset if you get stuck.
Saw Will_Wam's Turbo Racers and thought it needed a little more turbo. So I added Nitro boost. Then I got rid of the instant death, 'cuz I like to play, not die. Cleaned up code. Took out unused sound effects. Added a lap counter. Then decided to overhaul the entire project, and swap out all the graphics for Super Off Road pixels. Found sprite sheets at The Spriters Resource, by Yawackhary. It's getting somewhere, but I keep getting frustrated with the limitations of Scratch. I absolutely love Scratch beyond just about any other project on Earth right now, but determining the direction of collision isn't easy, and the car keeps wanting to drive through the barriers. It doesn't seem to register stacking "not touch" commands. I also had to rewrite the Accel code, because I was running into floating-point math issues. If you take 0.15 and continue to add 0.1 to it, you don't get exactly 0.25 and 0.35 as you'd expect. I made a project to illustrate that - http://scratch.mit.edu/projects/23193468 I feel like it might get too laggy if I actually build it out to be the full game. It seems slow as it is, especially when you drive under the banners. Maybe I'll put in an option to turn them off. I know it's not complete. You have to figure it took those arcade programmers months to accomplish their full game. I cobbled this together in a couple days. I guess the great part is that this generation of kids that grow up on Scratch will be more open to the possibility that programming can be shared, and great things can come of it.
