Computer Science Dice Game

 Analysis
Try and create 3 or more key success criteria for your program.
Success Criteria:

               Replay Ability (Previous scores, reset game)
               User-friendly (Clear instructions, functional time pauses)
               Authentication (Are they an authorised player?)
               Resolving problems (instances of a draw, similar top scores)
               Visual aid (Showing player name, score, rolls, score changes)
               Limited functions (Only deduct or add points once, don’t let the score go past 0)
               Advanced functions (files, randomisation)

 

Decomposition
Design

You may like to create a flow chart which will show broadly how your program will work.  If so include your flow chart in this section.
You must create pseudocode for a part of your program (minimum of 15 lines)
Pseudocode – Main Body of the game (Without SaveScores function)
START
AuthenList = [testplayer1;password1, testplayer2;password2, testplayer3;password3]
INPUT Player1Username
INPUT Player1Password
IF Player1Username AND Player1Password IN Authenlist:
 OUTPUT ‘Authenticated Player’
 INPUT Player2Username
 INPUT Player2Password
 IF Player2Username AND Player1Password IN Authenlist:
  IF Player2Username NOT Player1Username:
   IF Player2Password NOT Player1Password:
    OUTPUT ‘Authenticated Player’
    INPUT Commence BY player1
    IF Commence = ‘START’:
Player1Score = 0
Player2Score = 0
     P1GO()
     Roll1 = CHOOSE RANDOM 1-6
     Roll2 = CHOOSE RANDOM 1-6
     OUTPUT Roll1, Roll2
     Score = Roll1 + Roll2
     IF Score IS EVEN:
      Score = Score + 10
      ADD TO Player1Score
     IF Score IS ODD:
      Score = Score – 5
      UNLESS Score = 3
      THEN Score = 0
P2GO()
     Roll1 = CHOOSE RANDOM 1-6
     Roll2 = CHOOSE RANDOM 1-6
     OUTPUT Roll1, Roll2
     Score = Roll1 + Roll2
     IF Score IS EVEN:
      Score = Score + 10
     IF Score IS ODD:
      Score = Score – 5
      UNLESS Score = 3
      THEN Score = 0
     LOOP P1GO AND P2GO (4)
     IF Player1Score > Player2Score
      OUTPUT Player1 ‘IS THE WINNER
     IF Player2Score > Player1Score
      OUTPUT Player2 ‘IS THE WINNER’
     IF Player1Score = Player2Score:
      P1 = CHOOSE RANDOM 1-6
      P2 = CHOOSE RANDOM 1-6
      IF P1 > P2:
       OUTPUT Player1 ‘IS THE WINNER’
      IF P2 > P1:
       OUTPUT Player2 ‘IS THE WINNER
      IF P1 = P2:
       RETURN TO Line{IF Player1Score = Player2Score:}

Test design

 Think of tests that you can carry out to see if your system works
Remember to try and use normal, boundary and erroneous tests.
If you wish to, you may add more tests to the table.

 
My tests:

Test

What am I testing?

What data will I use?

Normal/Boundary/Erroneous?

Expected Result

1

Element In a list

String

Normal

Authenticates the player

2

“”

“”

Boundary

Doesn’t allow entry as the same person

3

“”

Any

Erroneous

Not allowed entry since it isn’t defined

4

Given input

Integer -> String

Normal

Performs option

5

“”

Out of range integer

Boundary

Terminate with error message

6

“”

String

Erroneous

Terminate with error message

Test

What am I testing?

Expected result

Pass/Fail

Do I need to change my program?If so, how?

1

Whether or not the SaveScores Function truly write each value properly

Leaves a singular line after each one, minus the last one.

Only just a fail, it just adds an extra unneeded empty line at the bottom of code. Also, position 4 didn’t seem to work

There isn’t really anything I can do, since there is no function the does the opposite to (moving a line down)

2

The occurrence of a tie

Go to tiebreaker, roll 2 separate numbers, then announce winner or reset the program.

Pass, but the player and ‘IS’ is joined together, but this is an easy fix

I need to recheck my string concatenation and make sure there are gaps when needed

3

If my program prints the top 5

Prints the top 5, then returns to selection

Partial fail, it does print out the code

I could use a function, a while or for loop, or, though documented as risky or prone to breaking, execfile()

4

If they give a value option of something that isn’t 1-2

Prints an error message to tell the user to stay within parameters

Pass, and it is useful here since it is only at the start of the coding.

I don’t really need to change this since this is the main starting point, and it functions in a way that works, but may not be the most efficient.

5

If all the colour shortcuts work

Changing the colour of the text

Generally a pass, but the background plays up on the first one

I don’t need to change anything, but I may debug it a little to try to get the background to work.

Evaluation

Evaluate how successful your program was.  You may find it useful to refer back to your tests
You should reflect on any new skills you have developed

 
How successful was my program?
My program was relatively successful, however it did have a few flaws, some I could fix, some that I couldn’t work out how to fix. The gameplay is quite user-friendly with visual aids and simplistic controls, and resolves any ties or mistakes, either in a good or a bad way, unfortunately. I can admit it could be more robust and compact within my coding, considering the fact that my defined function ‘SaveScores()’ is around 188 lines long, due to the fact that the pre-defined functions didn’t function how I wanted them to. The main requisites for the game (5 rounds, saved scores, tie-breaker, etc.) have all been met to the best of my current standards, with some alternatives used. All in all, I think my work has the functionality and the basic look of the expected game, but in hindsight could be more compact, especially if I had some better knowledge of more advanced functions (e.g. arrays, 3D lists, importable functions, etc.). Another flaw with my coding is the viewing of the top 5 scores, since the program terminates after showing the scores, and I would put it into the while loop, but that would mean I would have to move all 405 lines over. In this case, I have instead put a warning on the choice, saying that the program will terminate if option 2 is selected as the pathway.
What new skills have I developed?
Apart from these difficulties in how my code needs to function, I have learnt how to manipulate lists using append, sort, reverse, pop, index, and truncate, all within something else I developed an understanding for, that being defining a function. The skills within this that I have made better are random.choice() and arithmetical operations such as and ==. I have also found out how to use colour within my coding to make it look better, and a form of ASCII text
