1 Game Design Level 3 Extended Diploma Unit 22 Developing Computer Games

2 Your task (criteria P3) Produce a design for a computer game for a given specification Must be a design you are capable of developing in HTML5 and JavaScript For confident programmers: Side scroller Platform Snake For less confident programmers: Breakout

3 Design techniques Storyboards Pseudo code Narrative Action lists Graphical tools

4 Storyboards

5 Storyboards A series of simple drawings created by games designers which show: The different stages of the game The order in which they will be played The appearance of: Start screens Levels Menus Scores How game development can be split and allocated to different developers

6 Story board for breakout Start screen Options menu Difficulty? Levels Different numbers of bricks? More than one ball? Scores Time taken? Points? Game over screen

7 Story board for breakout Start screen Welcome To Breakout A multi-level game to challenge your reaction and strategy What level can you reach?

8 Story board for breakout Instruction screen Breakout Control the paddle to deflect the ball towards the bricks Each strike destroys a brick. Clear all bricks to reach the next level. Use cursor keys or press m to use the mouse Press spaces to start

9 Pseudo code Cross between programming code and English Designers understand: Game features What makes good games What motivates players to continue Programmers understand: How the code works Pseudo code is used to communicate between designers and programmers

10 Pseudo code for Breakout If ball is at bottom of screen and ball is on paddle Else End If Then reverse direction End game

11 Pseudo code for Breakout Activity Using your breakout.js Write Pseudo code for the paddle movement function Write Pseudo code for the end game code.

12 Narratives This is the story of the game Encourages the player to find out what happens next Creates atmosphere (scary, tense, calm) Creates emotional link to characters Acts as carrot and stick Creates rewards More or less important depending on genre

13 Narrative for breakout Increased tension in levels Speed? Number of balls? Rewards Faster paddle? Slower ball? More points if more than brick knocked out per bounce? Different ball shapes or sprites?

14 Action lists Splits the complete development job into individual tasks Shows them in order Shows who will be doing them How long they take When they need to be done by The skills and resources needed Used by the project manager Given to the whole team

15 Action list item for Breakout Create storyboard Duration: 1 week Developer: A student Dependency: Choice of game Due by: April 27 Skills: Drawing Resources: Graphical package Create graphics. etc

16 Assignment 2 P3 Produce a design for a computer game for a given specification. P4 Develop the game. M1 Determine appropriate data types for a computer game and show how they are declared. M2 Use appropriate selection and iteration methods for a computer game D2 Explain how the structure and design of a game can assist in maintenance and capacity for extension.

17 Task 1 P3 Produce a design for a computer game for a given specification Your design must include Storyboards Pseudo code Narrative Action lists Graphical tools

18 Task 2 P4 Develop the game. A witness statement is required here plus all code listings to be submitted.

19 Task 3 M1 Determine appropriate data types for a computer game and show how they are declared Explain the data typing in JavaScript Decide which variables you will need Describe the type they will be eg text, number, array Include the declarations

20 Task 4 M2 Use appropriate selection and iteration methods for a computer. You should provide examples of code used in your game and explain where you have used them, why you have used them and what they achieve. Make sure you include at least two variations of if statement, a switch and nested loops.

21 Task 5 D2 Explain how the structure and design of a game can assist in maintenance and capacity for extension. Using comments Write small blocks of code functions Invoke existing code blocks - call a function Use consistent indentation Using sensible variable names

22 Assignment 2 Over to you.
