This is the (probably) final version of my roller coaster simulators. This one has adjustable speed, backwards momentum, 'speed' tracks, a new interface, and a lot more fun! You can draw and test your own coaster. Use the pencil at the start to draw a coaster that the car will move along by holding down your mouse. Press space while you are drawing to use your eraser to erase part of the track. Click on the red box to draw "speed" tracks, click the brown box to draw visuals (tracks which won't do anything except look pretty), and click the black box to draw normal tracks. Click "Start" to test your track, and click "Clear" to start over. Change the speed of the car by dragging the lever left or right. Fun things to try: loops or jumps. If you have more ideas or made a really cool track, feel free to comment. with nusic
