I added a new Fire component to the FlexLib library. This is a Flex component that creates a fire or smoke effect. It can be customized in a variety of ways, including setting multiple colors for the flame. Check out the demo app below to see a few different presets I came up with. Try playing around with the different controls and you’ll get an idea of the different kinds of effects that are possible.<\/p>\n
The key to this is using the perlinNoise<\/a> function of the BitmapData class, and the DisplacementMapFilter<\/a>. I don’t claim to be an expert on using these functions. Others have written about using them<\/a>, I just copied the same approach. <\/p>\n View the documentation<\/a> To get the source of the Fire component, download the FlexLib project<\/a> from Google code.<\/p>\n And don’t complain about this using a lot of CPU horsepower, go get a faster machine \ud83d\ude1b Or look at the source and figure out how to optimize it for better performance and contribute the improvements back to FlexLib<\/a>.<\/p>\n
