Code Playback

Teachers have access to all of the files that students produce on Codio. In order to see how these code files were built, teachers can use Code Playback. If your cursor is in the code file you want to see the playback of, simply select Tools->Code Playback menu. If you are looking into a multi-file program or did not have the file you want to investigate in-focus, search for the student’s file by clicking on the folder icon.

To watch the code be built, click the play button. You can change the speed using the Speed drop down which is in changes per second. To walk through the changes manually, you can use the “Previous change” and “Next change” buttons. You can drag along the playback slider to find points of interest.
