Practice Assignment 4

Last modified: February 20 2011 03:11:51 PM

If you don't remember how to do any of the steps (like, copying, zipping, etc), please refer back to Lab 1.

For this assignment, you will work on the Practice Assignment 4 scenario, located in /eng/class/notes/cse113/scenarios/PracticeAssignment4. You will need to copy that directory into your account. If you are working from home, you can copy the PracticeAssignment4.zip from the link. (Note that this scenario is similar to, but different from the scenario at the end of Practice Assignment 3, so you will need to copy over the new scenario to work on this assignment.)

By the end of this assignment, the functionality of the "ocean" scenario should be as follows:

The starfish will "move" randomly. That is with some random probability, each starfish will move. The exact percent of time the starfish moves is up to you, but you need to make it move less than 50% of the time.

The dolphin will turn left or right when the user presses the left or right arrow keys.

If a dolphin collides with a starfish, the scenario stops.
