# Learning Inform 7: Part 3

[Unlike my Twine Tuesday posts, I usually make and upload these videos within hours of starting the code for them. This means, like what happened last week, that if I don’t have time to write the code, I won’t even make it to the video part. However, I’m going to try to schedule these some in advance, so that might not be as as much as a problem going forward.]

In this video, I build on the museum setting from the last video and add some new rules. I also introduce using Basic Screen Effects to add more color to Inform 7 projects. For the next video, I will be expanding on the scenes I began in this and continue to use this setting as a basis for later stories.
