CS 1110/1111 – Spring 2015 – Partner Projects

Partner Project 2: Game Project – Due: Wednesday, April 22, 11:00 AM

Games, in addition to being fun, are also a great way to practice many aspects of programming. This semester we’ll create a game similar to the 1982 classic Joust. In our version we’ll have the two players be oponents instead of allies: they’ll ride giant birds and try to knock one another off their birds. You can try it either by running JoustDemo.jar or by importing into Eclipse JoustDemoProject.zip. The a, s, k, and l keys control the birds.

You should work with one partner on this assignment. You should pick a partner in the Thursday, 2 April lab. Your partner

Problem 1. (Dragon Curves) Write a program Dragon that takes an int value N as

command-line argument and prints the instructions for drawing the dragon curve of

order N. The instructions are strings of F, L, and R characters, where F means “draw

line while moving 1 unit forward,” L means “turn left,” and R means “turn right.” A

dragon curve of order 0 is just the character F, and a curve of order N is a curve of order

N −1 followed by an L followed by a curve of order N −1 traversed in reverse order with

R replaced by L and L replaced by R.

Dragon curves of orders 0, 1, 2, and 3 and the corresponding instructions are shown

below.

Problem 2. (Visualizing Dragon Curves) Write a program DragonPlot that reads from

standard input the instructions produced by Dragon (from Problem 1) for drawing a

dragon curve, generates a drawing of the curve (shown below), and saves it in a file
