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.

Learning Objective LO: Learn how to develop a simple application using the Touch Develop Environment. Lesson Objective: - Students are learning how to develop a simple application which will move characters up and down and it will introduce them to the touch environment.

Setting Up Touch Develop Go to www.touchdevelop.com Sign in using a windows live ID. Click on the open link at he top of the screen. Click on the Create Script button Walk your students through how to get logged on to the touch develop environment.

Introduction What is “main()”? What is “Post to wall?” What is a “Sprite?” What is a “Variable?” Main() – Students will need to know that main is the main function of your game. It will run this function before anything else. If you have used Kodu as a starter you can link this is with Pages. Explain that other functions will happen later on. Post to wall – Get your students to experiment with changing this message and pressing the run button. Get a quick discussion about the changes and what it does. Talk to students how plain the game is and what we would like to do. What is a sprite – Get your students to understand and maybe even take notes. A sprite is a character or computer graphic which may be moved on screen. It can be manipulated in many ways. What is a variable – Get your students to think of a variable as a bucket. It is something which can be emptied and refilled with information. For example if you had a name variable. It could store lots of different information. If you emptied the bucket, you would have room for a new name. Explain that you can have a variable which is local and a variable which is global and used all over the program.

Learning Outcomes Touch develop to build a application which : Has a background image Has a width for 480 and a height of 800 Upload an image and include a sprite. Upload a number of different images to use as characters throughout your application. Talk about what the students will be expected to achieve after their first lesson. This might take 2 lessons for some students but the help sheets will be attached to introduce this to younger students.

Setting a Background Create a variable for the height – As Number Create a variable for the width – As Number Create a variable for the board – As Board Create a portrait board using the 3 variables. Post to wall Use the hand out to support this task. Talk about what the students will be expected to achieve after their first lesson. This might take 2 lessons for some students but the help sheets will be attached to introduce this to younger students.

Setting up a Sprite Upload your picture. Set up a variable for the image as a Sprite. Create the picture on the board. Set the height, width and position. Set the friction. Use the hand out to support this task. Extension – Use what you already known to make variables for the height / width of the character. Talk about what the students will be expected to achieve after their first lesson. This might take 2 lessons for some students but the help sheets will be attached to introduce this to younger students.
