There are a lot of Flash physics engines available to use. I've only tried Box2D, APE, and Foam. Foam is my favorite so far. I actually like the options of Box2D better but it's just not as ActionScript-friendly as Foam.
Foam sets up the easiest of these 3 engines for an ActionScript only project...In my opinion, setting it up to use in my Flex projects takes a little more work depending on what I use it for. Seeing the end result of it is fun to watch.
Below I'm currently using my polygon editor to test Foam out in Flex.
Does anyone out there throw together rough tools to solve eccentric problems that drive you nuts?
I run into problems with point data occasionally and it's hard to find a solution for using the data, when I can only view the problem in messy code format.
This sometimes leaves me wondering if the function I'm writing is even working correctly or not.
The example below is a rough tool I made to visualize and edit the Array format of points I usually work with. Over time I have transformed, gutted, and replace its code for different tests I needed it for. (The insides are not pretty.)
Yep it looks like a drawing tool, just not intended for that. I've only added certain "drawing" features I needed to make it easy to visualize the data I'm working on.
Looking at my previous post I felt the isBehindLine function served it's purpose, but if I get a more complicated problem similar to a raycasting test with imaginary ray of arbitrary width I would need to know more information where a Point is relevant to a Segment.
The "whereAboutSegment" function will return a String this time, with more detailed info of the Point's where-a-abouts instead of just knowing if its behind a line.
