Greenfoot sound play3/14/2024 ![]() ![]() There is unfortunately a Java bug that cases problems with sound recording on some USB connected microphones. However, the built-in recorder should be sufficient in many cases. If you want more sophisticated sound editing, you can still use third party applications (such as Audacity). The functionality is very simple - just recording and trimming is supported - but this is what you need most of the time. It can be found in the Controls menu, and you can now record your sounds directly from within Greenfoot. Greenfoot now has a built-in sound recorder. Right-clicking the world itself (or indeed the grey background behind it) will show the world object context menu and lets you invoke the world methods. We have now removed this name, and instead made the whole world area right-clickable. ![]() It had, in fact, almost easter egg-like quality. It was bad UI design, since nothing in the name indicated that this was clickable. The problem was that this functionality was quite hidden, and many users never discovered it. It had a right-click functionality, that let you access the world object’s context menu to invoke instance methods on the world object itself. The name of the world used to serve as a placeholder to represent the world object itself. Sharp-eyed users may notice one small change: the world name, that used to be shown above the world in the main window, is not there anymore. “Where’s the new stuff?”, I hear you ask. The Greenfoot main window looks pretty much as it used to look before. (Yes, we are now supported by the good folks at Oracle, instead of Sun Microsystems, after Sun was swallowed up by Oracle.)īut after that, it all might look rather underwhelming at first. The first thing users will notice after upgrading is a new splash screen. * Use the method aySound( features are available in the editor, for processing and recording sound, for editing images, debugging your programs, and more. Here, I will summarise the most interesting changes (at least those that users can directly see – there are many internal improvements to performance and stability that I won’t discuss here).
