2D Pie Drawing

Update: Here is the sample updated to XNA 4.0. Thanks UberGeekGames.


After I’ve seen some people asking how to do this on the forums, I decided to make a small class that allows us to draw Pies in 2D in XNA.

To use it, just create a new Pie2D object. The constructor receives parameters for the radius, angle and tessellation. These can also be modified at runtime, and the shape will be altered appropriately.

I made a sample that shows how to use this class. You can download it here: Pie 2D sample

A pie could be useful in 2D games for various effects, like enemy visibility area, flashlights, shields, radars, time indicators, etc.
