The first draft of the tutorial videos for Composer scene management are on the site. If you have access to either the Beginning Game Dev course (a/k/a Froggy) or the Business Apps course, you should have access to the Composer course. Look in the Member Dashboard for the link.
Yes, as usual when I create a new course I consider it a first draft until a number of people have gone through it and given it a (metaphorical) thumbs-up. Because while I’ve been doing tutorials for a long time, I sometimes miss the mark in what I’m trying to get across. When you know a subject very well it’s sometimes hard to remember what it was like as a beginner.
So if you find something in the course you think isn’t quite clear, please leave a comment and let me know. If you think something’s perfect, leave a comment for that, too. 😉
