4 Pre-day Questionnaires

5 This is a Computer What do computers do? How? Computer Science: What do you already know about Computer Science? What is Computer Science?

6 Fact: Computers aren t very smart! In order for the computer to do ANYTHING it has to be told specifically what to do. It needs tasks breaking down into simple steps. This is what programming is! I am SILLY!

7 Fact: You can make them very smart! Computers are incredibly fast, accurate, and stupid. Human beings are incredibly slow, inaccurate, and brilliant. Together they are powerful beyond imagination. Leo Cherne 1968.

8 Why choose Computer Science? Watch this: v=1o0oa3fa2ws&feature=related

9 Modeling in the Real World Clear, concise instruction giving is important. Solving real problems in addition to making fun games, what kind of problems can you think of that could be solved? What jobs and careers are there? What do you think it is like working in the Computing industry? Is Computing and Computer Science only about programming? Watch this:

10 What careers are available? Designer Technician Teacher Database analyst Developer Engineer Researcher Consultant

11 What Developer jobs are available? Frontend/UI Developer Permanent, London 35k - 46 pa + bonus IT Developer Permanent, Edinburgh 35k - 50 pa + Package Web Developer Apprentice Permanent, Edinburgh 9,600 pa Java Software Engineer Permanent, Cardiff 30k - 40k pa Mobile App Developer Permanent, Birmingham 30k - 36 Software Developer Undergraduate position, Swansea 17k - 18k

12 What is Object Orientated programming? Object Orientated means that the programming language is based on Objects. These Objects are blocks of code that can be reused after they are written. What are the benefits of using Object-Orientated programming? Java is an example of a programming language that is used daily in organisations throughout the CS industry.

13 Example of code This is an example of code for a computer in Java. Class MyFirstJavaProg! {! public static void main(string [] args)! {! System.out.println("Hello World!");! }! }! Any ideas what this could mean?

14 Objects and Classes This is an object: This is an class: RoboGirl: Lisa! Class: Robot Name RobotNumber GroupName GroupNumber

17 Real Programming Year 7s Year 13s attend a range of Technocamps workshops learning introductory programming skills using Drag and Drop programming environments. You will be experiencing a real programming environment, exposing syntax errors and how to code properly.

18 Greenfoot

19 Greenfoot Here is an example of what you can achieve using the Greenfoot programming environment: Watch this: v=f7qqwvmb64u&feature=relat ed

20 Greenfoot Interface Class!Diagram! World!

21 Greenfoot Interface Subclass! Constructor! Instance!of! Wombat!class!

22 How to make Objects Act Click on Act in the execution controls. Each object has a built in Act method, so any instructions added here are run when the Act button is pressed. In the Wombat example, the leaves are currently not commanded to do anything, however the Wombats are programmed to move forward. Place 2 Wombats in the World and press Act, what happens? Try placing several leaves on the World. Press Act. What happens when the Wombats come across the leaves?

23 Brackets in Java () round brackets: Known in the USA as parentheses, in the UK these are known as standard brackets. They are used in mathematical expressions, surrounding the parameter lists for method calls. [] square brackets: Known in the USA as brackets. In Java these are used for arrays. {} curly brackets: These are called braces or squiggly brackets. In Java, these are used to surround blocks of code such as methods of class content.

24 Movement Enter the amount of steps to move within the round brackets inside the Act method. This will run each time the Act button is pressed after the code is compiled.

25 Movement Next, underneath move(4); command the actor to also turn to the value of 3. See what happens after compiling and pressing Act what do you think 3 stands for?

26 Task Experiment with the code in this Act method: Make the circle the Wombat moves in bigger. Make the circle smaller. Try adding a different background. Try changing the image of the Actor.

27 Conditional Statements An If statement can be used to state the following: If a certain condition occurs, execute the following code Else, if anything other than that condition occurs, execute this code instead You can use IF statements in your code to get your Actor to react to keyboard input, such as the code snippet below:

28 Obstacles Add a new Actor, a rock has been used as an example. This will be your obstacle. You do not want this to move, so the code here does not need to be altered/ added to. Place a variety of rocks around the World. To place these at random, click WombatWorld and open up the code. Copy the RandomLeaves method and paste directly below, edit the name of Leaves to your given obstacle name and re-name the method so you do not have 2 methods with the same names.

29 Obstacles continued In order to stop the Wombat moving through the obstacle, add the below code to make a new method in the Wombat class: public boolean norocks(int x, int y) { World myworld = getworld(); List rocks = myworld.getobjectsat(x, y, Rock.class); if(rocks.isempty()) { return true; } else { return false; } } Remember to change the name of rock to whatever you have named your obstacle.

30 Randomly moving Actors You can get your Actors to randomly move around the World, this keeps your game exciting and will be different each time you or another user plays the game.

31 Spinning collectables To add some visual elements to your Greenfoot game, you can get your collectables (currently the collectables are leaves on the WombatWorld) to rotate as the Wombat is moving around the screen collecting them!

32 Adding Sound In the Wombat Act method you can add a playsound command that will play a saved sound file when the method is run, for example: Greenfoot.playSound( file.filetype );

33 Score Score is sometimes the most fun part of a game. It allows other players to compete against one another without having to play at the same time. It also allows a user to assess how well they play the game, progressing and improving their score each time. Implementing a score as a counter within the WombatWorld will greatly improve the quality of the game.

34 Let s make our own game Lets make our own games and publish them, have a go at the following: Change the images (you can upload your own) Change the size of the game (in WombatWorld the current size is 8x8) Scoring Use of obstacles Different images for different obstacles Adding sounds Remember, there is a list of other commands on:

35 New game: PONG! You can create a new scenario called Pong. Add the list of classes and subclasses of Actors on the right hand size to your new world. The aim of the game is to bounce the ball into the oppositions goal, but it is key to protect your own goal as the other player will be trying to do the same thing and score by knocking the ball into the goal you re protecting.

36 Players Controlling multiple players will allow us to play the game against one-another. The right player will use the standard arrow keys on a keyboard to control its Actor. The left player will use the following keys on a keyboard: W = up A = left S = down D = right

37 New game: Shooting Game! You can create a new scenario called Shooting. Add the list of classes and subclasses of Actors on the right hand size to your new world. The aim of the game is to use a laser on a rocket that you can control the movement of, to shoot the aliens that appear in the created World.

38 New game: Crab Game! On the Greenfoot website, download the crab scenario and open on Greenfoot. This may already be downloaded, if not follow the link below: The aim of the game is to control the Crab using the left and right keyboard arrow controls to collect and eat the worms as the crab spins. Alternatively you can make the crab follow your mouse around the World. Make sure you avoid the lobster!

39 New game: Marble Drop! You can create a new scenario called MarbleWorld. Add the list of classes and subclasses of Actors on the right hand size to your new world. The aim of this game is to guide a marble left and right using the mouse to try and fall through the gaps in the floors which move up the screen.
