# java game Joust

## 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
