racecarTurtles by MossLizard

A recreation of a game my family would distract me with as a graph-paper-obsessed child. Carve out a racetrack and carefully manage your turtle's velocity to reach the end before your friends do!

+++ PLAY +++

On your turn, stand in front of one of the monitors and click the direction on the compass you want the turtle to accelerate in. The turtle will move that much on this and all subsequent turns.

You can accelerate 1 unit north or south, plus 1 unit east or west. You may also choose not to accelerate by clicking the @ symbol, in which case your turtle's velocity will be unchanged. If a turtle collides with a wall or other turtle, it will crash, losing a turn and setting its velocity to 0,0! Avoid this!

A turtle ends the race when it ends its turn over black or white wool. Once all turtles have ended the race, the results will be shown and the program will end.

+++ SETUP +++

This project contains two files: racecar and racecarManager. Install raceCarManager.lua on a computer and attach a few 1x1 advanced monitors in places where the track is visible. These will be the controls for the turtles. Attach a wireless or ender modem, and alter raceCarManager.lua to provide the correct names of the modem & monitors. Install racecar.lua on as many turtles (basic or advanced) as you want to race. Attach a modem to either side of the turtle. A GPS constellation is NOT required, as the turtles have minimal navigation and use dead reckoning

Dig out a 1-block deep racetrack of some sort. The shape is up to you, but I would suggest making it big and wide. The example given in the screenshot should be considered the minimum size. Replace the blocks at the end of the track with black or white wool... perhaps even a checkered flag effect? Note that, while the turtles must be placed facing north, the track does not need to start off going north. It doesn't even need to start off going in a cardinal direction! Try diagonals! Run racecarManager.lua on the computer. Place the turtles on the starting line, FACING NORTH, and run racecar.lua on each. Click [SYNC] on the turtle UI in the order you want turns to run in. Once all turtles appear on the computer UI, click [START] to start the game.
