I wanted to make a conversational AI with two characters, Avery and Jaime. The user would type Avery's dialog and the AI would speak through Jaime. This is possible by using an external AI bot, such as api.ai. Scratch provides a way to interface to the outside world using Extensions. Extensions are primarily written in Javascript. This is the direction I was going. Self-written extensions are called Experimental Extensions (EE). I learned that these EEs have to be submitted for approval to be included in ScratchX. This approval process would take more time than what was available for this project. ScratchX is experimental Scratch (a sandbox where EEs can be used). I ended up creating a very short, automated dialog for my two characters. Part of what Avery says is randomly chosen from a list. Jaime appropriately responds based on the tone of Jaime's statements.
