Lab 3: 2D Graphics & SMFL

ECE 4122/6122 Lab 3: 2D Graphics & SMFL
(100 pts)
Problem 1: Pacman Game (100 pts)
Write a C++ application that uses SFML to create a simple pacman game.
Game Rules:
• (~5 pts) Display the provided pac-man.bmp at the start of the game with the extra text
o PRESS ENTER TO START
 in the middle of the window.
• (~20 pts) Once the user presses the ENTER key the game starts with
o pacman located as shown above
o all four ghosts start at the same location as shown above (bitmaps provided)
o place the four power ups as shown above
o place the coins as shown above
• (~10 pts) The ghost’s initial direction is determined randomly and when a ghost hits a wall
its new direction is chosen randomly.
• (~20 pts) Control the location of pacman using the left, right, up, down arrow keys.
• (~10 pts) Determine a game speed that makes the game fun to play (not too slow and not to
fast)
• (~10 pts) The game ends when
o one of the ghosts comes in contact with a non-powered up pacman
o pacman consumes all the coins
o user presses the escape key.
• (~5 pts) When pacman eats a powerup he can eat ghosts for 5 seconds. Ghosts that are
eaten are gone forever.
• (~15 pts) Pacman and the ghost cannot go through walls.
• (~5 pts) Pacman and the ghost can go through the middle tunnels on each side.
• You do not have to handle resizing the window. Just use the image size.
Suggestions:
• Use invisible rectangles to represent the location of the walls.
• Use circles to represent the coins and power ups.
• Use vectors to hold locations of coin, powerup, and wall objects
• Use the Chapter 5 example from Beginning-Cpp-Game-Programming-Second-Edition
as a starting point.
Turn-in Instructions:
Two methods:
1.
a. Upload a video(s) of your game running and demonstrate the “Game Rules” above.
Multiple smaller videos are fine, just make sure that the name is representative of
the game rule being covered.
b. Put all the code files you created into a zip file called Lab3.zip and upload to
canvas.
2.
a. The TAs will build and run your code.
b. Use the Chapter 5 example from Beginning-Cpp-Game-Programming-SecondEdition to develop your code. Remove the existing timber.cpp file and place your
new source code files in the code directory. Once you have finished your
development, zip the Chapter 5 folder with your changes into a zip file called
Lab3.zip and upload to canvas.
Grading Rubric
If a student’s program runs correctly and produces the desired output, the student has the potential to get a 100 on his or
her homework; however, TA’s will randomly look through this set of “perfect-output” programs to look for other
elements of meeting the lab requirements. The table below shows typical deductions that could occur.
AUTOMATIC GRADING POINT DEDUCTIONS PER PROBLEM:
Element Percentage
Deduction
Details
Does Not Compile 30% Code does not compile on PACE-ICE!
Does Not Match Output Up to 100% The code compiles but does not produce the correct outputs. See
point values above.
Clear Self-Documenting
Coding Styles
10%-25% This can include incorrect indentation, using unclear variable names,
unclear/missing comments, or compiling with warnings. (See
Appendix A)

Appendix A: Coding Standards
Indentation:
When using if/for/while statements, make sure you indent 4 spaces for the content inside those. Also make
sure that you use spaces to make the code more readable.
For example:
for (int i; i < 10; i++)
{
 j = j + i;
}
If you have nested statements, you should use multiple indentions. Each { should be on its own line (like the
for loop) If you have else or else if statements after your if statement, they should be on their own line.
for (int i; i < 10; i++)
{
 if (i < 5)
 {
 counter++;
 k -= i;
 }
 else
 {
 k +=1;
 }
 j += i;
}
Camel Case:
This naming convention has the first letter of the variable be lower case, and the first letter in each new word
be capitalized (e.g. firstSecondThird). This applies for functions and member functions as well! The main
exception to this is class names, where the first letter should also be capitalized.
Variable and Function Names:
Your variable and function names should be clear about what that variable or function is. Do not use one
letter variables, but use abbreviations when it is appropriate (for example: “imag" instead of
“imaginary”). The more descriptive your variable and function names are, the more readable your code will
be. This is the idea behind self-documenting code.
File Headers:
Every file should have the following header at the top
/*
Author: your name
Class: ECE4122 or ECE6122 (section)
Last Date Modified: date
Description:
What is the purpose of this file?
*/
Code Comments:
1. Every function must have a comment section describing the purpose of the function, the input and
output parameters, the return value (if any).
2. Every class must have a comment section to describe the purpose of the class.
3. Comments need to be placed inside of functions/loops to assist in the understanding of the flow of
the code.
