AI2: Interactive Blocks Learning Too

A tool for learning how AI2 beta language blocks work (formerly known as built-in blocks)

I have just completed updating this interactive learning tool for the current beta release of AI2. Interactive examples for all built-in blocks are provided.

All langage blocks are supported (plain text blocks testing is supported if the PlainTextLibrary.apk is installed)

Features:
⦁ access to the online MIT AI2 beta language blocks reference
⦁ ability to modify input values for testing examples
⦁ 'Edit' mode for testing the project with the emulator or Companion app and adding additional features
⦁ 'View' mode (the default) for the using the packaged app as a reference tool
⦁ more examples can be added by using the models provided

---
MIT AI2 has been released for classroom instruction as of December 3, 2013. App Inventor Classic will continue to be supported through June, 2014.

Really nice job!

This project developed with AI2 blocks allows the developer to test the function of some of the available blocks.
The blocks that have only a description of their usage may at a later time have interactive examples as well.
This version demonstrates the Control blocks (if, choose, foreach, etc.) initially. Other block types may be added later.
You are welcome to contribute examples of other block types to this project and post your version as a reply to this post.

Thanks. I am uploading an update that adds Logic block examples as well.
