Catchy title, worth to consider. While working on the AudioTool, we are continuously searching for better workflows. Joa Ebert has written two plugins for Eclipse that helps us a lot to deal with such a huge project.
To make it clear: I don’t love Eclipse. It is still a love-hate relationship and I am often fighting against its philosophy. So far, nothing comparable platform-independent in sight.
If your project consists of a bunch of SWCs, you often want to compile them first and your application afterward. Use MetaLaunch to launch several Eclipse launchers from a list.
PBDT – PixelBender Development Tool (free)
Adobe PixelBender Toolkit is not event worth to consider as a code editor, I am afraid. PBDT instead supports semantic highlightning and basic refactoring for your PixelBender shader source code. It even compiles your code in the background. This gives you a very nice workflow in developing shaders.
FDT – Flash Development Tool
Not to forget the sophisticated Actionscript development tool by powerflasher. People often think, you need to be an expert in Actionscript to get benefit from it and still prefer to use the Flash IDE. On the contrary, using FDT helps you learning AS3 with tons of useful features.
