An update to "DriftCar", this project adds a scrolling background - DriftCar always needed more real estate, and I was curious about scrolling in X and Y. Arrow Keys to Steer, Up Arrow to Accelerate, Down arrow for brakes. The "world" for the car is comprised of 4 sprites: UpperLeft, UpperRight, etc., with the "rotation center" of each in the corner that will be the center of the "world". This lets Scratch push the background almost off the screen so that the whole world is available. The "Map" Sprites are a bit crude... Sorry. The variable displayed in the upper left is reset (along with the timer), when you press "t". It counts updates (increments each time the program does a "move") for 10 seconds, then divides the number by 10 and stops, giving an idea of the "frame rate". If you download and are "looking at" a sprite that does a lot of calculating (like the car), it gives a value that is about 1/2 of what presentation mode gives. I'm curious what it will show in "Java".
