New version:

RabbitHunt2.zip

New features:

• More obvious turns. The rabbit's step and the fox's step are now shown separately, rather than together. This slows the program down a bit and doesn't look quite as neat, but it's easier to see what is going on. This is not a change in the model--the fox and the rabbit have always taken turns. The only difference is how it looks on the screen.
• Instant Replay button. If you ever watched a hunt and wondered, "What just happened?" now you can use this button to see the same game over again. However: this only works if you use my random number generator, static int random(int min, int max), defined in the Animal class. If you create your own random number generator to control the rabbit's moves, it's not possible for me to reset it to the beginning.
• Visible looks. When you are single-stepping (using the Step button), you will see exactly where the fox and the rabbit look. The speed control also controls how rapidly the animals look around.
• Better speed control. The speed control has been re-calibrated so that you have better control over fast games.
• Grading program. To quickly run through 100 games and see how often your rabbit escapes, start with the void main(args) method in Grader rather than the one in RabbitHunt. We will use this program (or something very like it) to grade your program.
• Better legality checking. The rabbit (and fox) are not allowed to pretend to be in some location they are not (that is, you can't use a mirror to look around a bush). The new program, while not perfect, avoids some simple ways to cheat. Please don't try to circumvent these.
• Additional constants. The two new constants Model.NUMBER_OF_ROWS and Model.NUMBER_OF_COLUMNS have been added, in case your program wants to know the size of the field.

Bugs:

• The "disappearing Speed scrollbar" has been fixed.
• The display still does not redraw properly after uncovering or resizing the window.

Grading:

Turn in your Rabbit.java file via Blackboard by Noon, October 31. Do not supply any additional files; Rabbit.java is the only file you are responsible for. We will supply the rest.

We will run your program at least 100 times, using some version of Grader (not necessarily the exact version that you have). Your grade on the program will be the percentage of times that the rabbit escapes, plus some points for good style.

Style points will be computed this way. Perfect style is worth 20 points; you will get one point less for each style error that I find in your program, down to zero points. If you make the same style error in several places, you will lose several points for it. For this assignment, "perfect style" is defined by Rule 1. It would be a good idea to read through Sections 1 through 5 of the style book in order to see the kinds of things that may be counted.
