This document discusses using TouchDevelop to build mobile games and apps. It introduces TouchDevelop and some important coding concepts like objects, functions, parameters, variables, and conditional statements. The agenda includes a TouchDevelop tour and lessons on these concepts, as well as loops and using "on every frame" to continuously check conditions. Resources are provided for teaching TouchDevelop, including pre-built games and tutorials that can be customized.

- 4. Why TouchDevelop? Its a snap to learn. You learn coding concepts without worrying about semantics. It makes building mobile games and apps easy. It runs on anything (laptop, desktop, tablet, phone). You can share your code and creations with friends. Its free All you need is a browser.
- 5. Which browsers can I use? TouchDevelop is supported on the latest versions of most browsers. To avoid a delay in your classes, make sure ahead of time that the browsers are updated For a full list of supported browsers, see here: https://www.touchdevelop.com/app/current.browsers
- 6. The Agenda TouchDevelop tour Important Coding Concepts: Objects, Functions and Parameters Variables The TouchDevelop coordinate system Conditional statements On every frame Loops Play time! :D Resources for teaching and learning
- 10. What You Need to Know Important Coding Concepts
- 11. Objects, Functions and Parameters object function parameter Object: a representation of something in the game Function: performs an action on the object it is associated with Parameter: specifies the value of the function
- 12. Variables A variable holds data that can be used throughout a script. Every variable has a name, a type, and a value. A variables type describes the kind of data the variable can hold. For example: A number, a string, a sprite In TouchDevelop, a variables type is determined when it is initialized.

- 14. Conditional Statements A conditional statement is special code for making decisions based on some condition. So whats a condition? Anything statement that can be either true or false. If I am hungry, then I eat. The action taken if the condition is false. The action taken if the condition is true. Otherwise, I sleep. The condition. (Its either true or false.)
- 15. In code, conditional statements are also called if-then-else statements Condition Code to execute if the condition is true goes here. Code to execute if the condition is false goes here.
- 16. BUT you have to pay attention to when the condition is checked
- 17. Computer games are a series of very fast frames Frame 1 Frame 2 Frame 3 Frame 4 Frame 5 Frame 6
- 19. Use on every frame to perform checks continuously
- 20. Loops A loop is a special tool in coding that lets us write code once and repeat it as many times as wed like Repeat the following block of code X times: End of repeated block You get to specify this value. Whatever code you put here gets repeated X times. Tells the program that any code after this isnt part of the code to be repeated.
- 21. The syntax for a loop The number of times the code is repeated. The code that will be repeated.Tells the program that any code after this isnt part of the code to be repeated.
- 23. So how do I get started? Its easy! 1. Go to http://www.touchdevelop.com 2. Click . 3. And .
- 24. Resources for Teaching and Learning
- 25. Two Recommended Formats One-Day Event Provide students with a half- baked game to fix and customize Jetpack Jumper prompted tutorial Estimated time: 2 hours maximum Multi-Day Event Build a side scroller game from scratch Use CODExist MVA as reference Estimated time: 6-12 hours (flexible)
- 26. Pre-course checklist Will you provide students with devices or will they bring their own? Do you have a reliable internet connection? If the students will be watching videos or working with tutorials, have you asked them to bring headsets?
- 27. When teaching TouchDevelop Emphasize the excitement of coding Be prepared to handle students with different levels of coding experience Make sure to leave time for customization Encourage students to share their games, both in show-and-tell in person and online on social media Provide NEXT STEPS how can they continue once the program is over? Publish their game to app stores, build more games, etc.
