Project Notes

Same as MARBLE RACER by ericr and MARBLE RACER SBE(and 2[1].0) by jamie, but with new track designs. ----------------------- INSTRUCTIONS: Use the arrow keys to race your marble around the track to the finish line. If you slide off onto the grass, it will slow you down. If you hhit the red objects, you stop. What's your best lap time? HOW IT WORKS: The marble has variables for its x and y velocities. The arrow keys make it accelerate by changing the velocities. The grass slows you down by multiplying the velocities by a fraction. THINGS TO TRY: You can make your own tracks by drawing a new background. Just use the same shade of green for the grass. Try making obstacles (even moving obstacles!) that you crash into, or enemies that chase you. You could make a little accelerator ramp that speeds you up, or a teleporter portal.
