I noticed that some animators are trying to manage the sequence of their animations using the "wait" block.  Projects done that way tend to get out of sync, especially when you play them from the site. 
This tutorial shows how to manage dialogue and change scenes using the "broadcast" block.  It might seem like more work at first, but once you get used to it, you'll discover that editing your project becomes much much easier.


It might seem like more work at first, but once you get used to it, you'll discover that editing your project becomes much much easier.  Teaching this concept tends to create teachable moments around the ideas of planning and revision.

 

This is my first pass at makin a tutorial on this topic.  I'm very interested in feedback that anyone may have, particularly if you show it to your students.

This is really nice. I like the way I can zoom in to different parts of the code. One way that I might remix the project would be to show how to achieve the same project using wait AND using broadcast. And I might add a "previous" button at each stage. :)

Thanks for sharing!
