CSE 203 Closed Lab 4 Instructions

Table of Contents


1. Objectives

To learn (really, to re-invent or discover) how to simulate an object's bouncing against a vertical or horizontal barrier.


2. Set Up

  1. Two students should work together at one workstation.
  2. In one student's account, follow the instructions given below in section 3, Method.  Remember, trading roles (driver and non-driver) for each new session is a very good idea.

3. Method

  1. Starting with the program you created in Homework 4, Save As New Program and change the program's name and date.
  2. Figure out how to simulate the sprite's bouncing against the edges of the window.
  3. Program it.
  4. Test your program: change it slightly a couple of times, launching your sprite at the beginning at different angles.

4. Proctor Check-off

When you are satisfied that you have successfully followed the method, raise your hand and one of the proctors will check your work. Then you are finished with the closed lab.  It's usually better for your education not to leave the classroom very early.  Instead, start in on the homework that's due at the beginning of the next class.
