With Subversion in BlueJ, you can update and commit, but not branch or roll back to prior version.

So far, we have always only supported the team work aspects of the source control systems. While they are often used together, they each also make sense on their own: A single developer might use version control, or a team might use team integration tools without version rollback. Version control systems offer help in two distinct areas: One is, well, version control (which allows version rollback, etc), and the other is teamwork (which allows integrating code from multiple developers).

As before with Subversion, we support only a subset of its functionality. Git, however, has a somewhat different model of work. So we have now moved with the times: We have removed support for CVS (which was always a bit terrible) and added Git support. Simultaneously, free Git repositories – such as GitHub – are flourishing. This is not surprising: Git has become the most popular version control system for some years now, and even though Subversion is often good enough for educational situations with small projects, publicly available, free Subversion repositories have disappeared quickly over the last few years. People have asked us for support for Git for quite some time. Let’s go through the main features in a little more detail, and I can tell you what we have done and why we have done it. These are support for CVS, JavaME and Applets. While we were at it, we have also removed some bits that – for various reasons – do not seem worth supporting anymore. These include the addition of Git support, support for writing and running JavaFX applications, a rewrite of a large part of the user interface in JavaFX, a tabbed editor, a fundamental redesign of error reporting, support for HiDPI displays and numerous smaller improvements. (I will say a few more words about that in a moment.) But independent of Stride, there are a number of other bits of new functionality that are worth mentioning. The most exciting new feature for me is the addition of Stride. How can I make so I can record time? (so I can make so if keypressed is <1second, play sustain sound.After concentrating on Greenfoot for some time, we have now worked on and released a significant new version of BlueJ: BlueJ version 4.0. The same applies if I hold longer than the audio clip lasts, it just ends there. So If I held the key for 2 seconds, and the audio was 3 seconds, it Would work but still play for the remaining 1 second even if the key is not pressed. If I used a different modified audio file, it would work, but only for as long as the file plays the audio. The issue is I don't know if there's a way I can track time, and it would cause the sound to not 'sustain' but just loop play. (or play a separate version of the sound, and maybe 'if key is not pressed', Stop playing sound (dont know if its possible, maybe with sound.stop ()) If a Key is pressed and held for <1 second, loop play a sound. (right now all it does it just play a short sound when I press) *context* Making a Piano where I can hold a key to sustain sound.

I am new to greenfoot, and trying to make a sound sustain while key is pressed.
