Another spinoff from my current library to optimize SWF/SWC files. Reducer is a tool that will make SWF and SWC files significantly smaller. There is currently a huge problem with filesizes. If you use the [Embed] tag with PNG images they are not compressed at all. For the Hobnox AudioTool we have been using the […]

See it as a knowledge base for ActionScript optimization techniques, data structures and code snippets. I would appreciate any feedback and suggestions for articles in those or other categories.

It was 40fps for […]

If you attended my session about bytecode inlining at FITC Toronto you might remember that I said I have a document covering a lot of common optimization techniques. After talking to so many of you and getting nice feedback I decided to release it in a state which is a work in progress. My main […]
