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:}

Flowchart – SaveScores

SaveScores Function

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

Testing

Show you have completed the tests you thought of
Identify if you needed to make changes to your program
Include the screenshots of the tests

My tests:

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
