This is a non-visual .swc component that you can use in your Flex Projects. It is specially optimized to be very fast since this kind of algorithms need much processing power.
The example project contains a very simple example. The constructor needs a BitmapData structure where white (0xFFFFFFFF) is walkable and black (0xFF000000) is non-walkable.
Once you have created the path finder object you may call the FindPath(startX,startY,endX,endY) method. This takes 4 parameters. The first two are the X,Y values of the start point and the last two are the X,Y values of the end point. If the method returns an array of some length then it has found a path. Each element in the array is itself an array which contains the X and Y coordinates of each step in the path.
* To use the example, just click and drag in the white areas. The mouse-down marks the start position and the mouse-up marks the end position. The path finder will then find the shortest path from start to finish.
A-Star Path Finder Sample:
Just click and drag in the white area. A mouse-down marks the start position and a mouse up marks the end position. Then the path finder will find the shortest path and paint it red.

The component looks great but I have 2 questions!
1.) Does it work with Flash?
Just saying Flex, using Flex library so not working with Flash?
2.) Is it possible to set the size of the line when calculate?
If there is space between “boxes” and the line is thicker, does it notice that it has to “take another way”?

1) The component is in .swc format which can also be used in Flash. I am sorry but I do not use flash so I could not direct you on how to use it in Flash. A google search might help though.
2) Actually the line and the area is a grid of 10 rows by 10 columns. Each dot on the line is a walkable grid tile from start to finish. So, the line is used only to depict how the algorithm works. This is actually a component without a visual appearance. It is a path finding algorithm which allows you to find a path on a grid of walkable and non walkable tiles.
