1. Introduction to Programming G50PRO University of Nottingham Unit 3 : Introduction To Scratch 2
Paul Tennent
Room C41

2. Agenda Common programming elements Pseudo Code Scratch Example
Scratch Demo
Course work

3. Common programming elements:
Variables
Conditional statements
Loops
Events

4. PseudoCode
PseudoCode is a compact and informal high-level description of a computer program
Uses the structural conventions of a programming language
Intended for human reading rather than machine reading
Compact and easier to understand fo humans
Language-independent

5. Example Cat Sprite() Loop Forever If (user hits right)
Point right
If (user hits left)
Point Left
If (user hits up)
Point Up
If (user hits down)
Point Down
Move slowly

6. Try PseudoCode Write PseudoCode to:
Move a car using up arrow to increase speed and down arrow to brake. Right and left arrows for directions.
If a wall is hit the car explodes and the car losses 1 life out of 3
Game is over if the car explodes 3 times

7. Who is responsible for what?
Structure your programs
Think – which sprites should be responsible for what actions?
Think – Where should your variables be defined

8. Example – Shooting Game
Bullet
Disappear
Add to user’s score?
Alien
Destruction effect
COLLISION!

9. Coursework 2 player car race online game
The game should offer a choice of multiple tracks.
When a player reaches the finish line the winner should be announced plus the time taken and a score.
Read the specifications on course web page

10. Coursework Check Similar projects online first
It is ok to reuse bits of code/ideas from other projects. Yet DO NOT copy a project and modify it.
Make sure to include in the Report references to other projects you used in your work on
Use Project notes to include simple user Instructions

11. Quick Review Create the software Write the documentation Design
Implement
Test
Write the documentation
Leave plenty of time to write the report
Proof read for obvious mistakes
Think about the structure of your writing

12. Software Demonstration
Wednesday 18th February
Make sure The game is usable online (clear instructions)
How does it look, feel?
