_Scripts

The Dynamic Import folder has the code for dynamically importing models both through asset bundles as well as GLTFUtility. To create asset bundles from the models the script can be run in Unity (Assets > Build AssetBundles).

The Tweedle folder contains code for reading and running Tweedle, the text representation of Alice code. It is in the Java/C# family.

• The File folder has class definitions for reading in manifests.
• The Grammar folder has the Antlr grammar.
• The Player folder supports the execution of Tweedle.
• The Parse folder has tests for testing parsing, code to parse an a3w project, code to select the zip folder, code to parse twe files, and the class to hold all the parsed information.
• The inner Tweedle folder holds the specific language elements.
