Abstract

• What is "Hackers of Catron"?o Electronic Settlers of Catan® board. Settlers

of Catan is a resource gathering and trading board game in which players compete to build the largest economy.

• What we will improve upon?o The game is really fun, but it takes too long to

set up. We will shorten the setup process.o Make resource gathering and spending

automatic. o This project intends to simplify the execution

of Catan without adding more complexity.

Initial Board Generation

• For each hexagono Assign a Resource from available Resource

Poolo Remove Resource from Resource Pool

• Select random edge hexagono Assign scarcity from list for each resource

hexagon in sequenceo Skip desert

• Go to wait for Pi To Boot

Initial Piece Placement

• Wait for players to join

• Randomly assign player order

• For each player 1-4o Wait for settlement placement and confirmo Wait for road placement and confirm

• For each player 4-1o Wait for settlement placement and confirmo Wait for road placement and confirmo Assign Resources

• Start Game Loop

Main Game Loop

• While turn isn't overo If dice roll pressed

i. Check if 71. If yes, make players with more than 7 resources

discard half and move thief2. If no, assign resources to players as appropriate

ii. Set Dice Rolled Flago If dev card played

i. Check if knight1. If yes, move thief2. If no, place 2 roads

Main Game Loop

o Check if piece purchasedi. If road, place roadii. If city, place cityiii. If settlement, place settlement

o Update Board Stateo Check if Ending Turn

i. If yes, clear dice rolled, move to next player

ii. If no, continue looping
