Explain what touch develop is to your students: TouchDevelop is a programming environment that runs on your mobile devices. You write scripts by tapping on the screen. You do not need a separate PC or keyboard. Scripts can perform various tasks similar to regular apps. Any TouchDevelop user can install, run, edit, and publish scripts. You can share your scripts with other people by publishing them to the TouchDevelop script bazaar, or by submitting them as an app to the Windows Store or Windows Phone Store.

POP QUIZ! Get your students to take the 5 minute quiz on keywords and test if they understand key words within programming such as variable, loop etc..

Learning Objective LO: Learn how to control a sprite to move using the X and Y co-ordinates Lesson Objective: - Students have learnt how to create functions and how to create characters which can move with the input. They have also learnt how to get characters to carry out actions based on bumping into others. In this lesson they’re going to learn how to get their character to move without input from the touch on the board.

Loading Your Previous Script Go to www.touchdevelop.com Sign in using a windows live ID. Click on the open link at the top of the screen. Click on the name of your script used previously. Walk your students through how to get logged on to the touch develop environment.

Learning Outcomes Use Touch develop to build an application which : Moves characters along X and Y co-ordinates without input Extend your game to use interactions: If characters bump into each other on the X and Y co-ordinates create an event or an action when this takes place. Talk about what the students will be expected to achieve after their second lesson.

What is X and Y? Show your students the difference between X and Y. Talk about positioning on the screen. Link back to previous lessons where they have talked about The character updating X or updating Y. They should have some idea of this already. Ask questions like, what would happen if X increased? What would happen if Y increased? What would happen if they were both increasing at the same time?

Creating a moving object Create a procedure click on new in the code section. Name the procedure to something you can remember. I.E – Score setup Write out your code which would set up the score on the screen. Insert your procedure into main().

Task: - Try and get a number of moving objects through out your game. Have a character which moves up and then down using a loop. Have a character which moves left and then right using a loop.

Extensions: - Extension – Edge of screen… Get your characters to do some, type of action if they happen to bump into each other. Edge of screen… See if you can get your character to change direction when it is at a particular position on the screen.

Hint…. It is basically that answer… however…. They need to use the correct buttons to get it working for Y or X.
