NonConvex shapes in SFML2.0
« on: August 29, 2013, 01:33:04 pm »
Hi, I just started learning SFML2.0 a few weeks ago and I wonder how I can make
non convex shapes. I learned how to make circle shapes and polygonal convex shapes
but is there any way to create non convex polygons? (I'm not taking about sprites that
can be taken from outside, but creating your own).  Thanks.

You can't do it directly. You must either split it into multiple convex shapes, or use an add-on library like Thor.

Well, I will try to search for this library. But if you already familiar with it can you recommend me some references or links that explain how to install this library you suggested? Thanks.

The class that can handle concave shapes is thor::ConcaveShape. You'll see how it is used in the Shapes example of the SDK -- but its API is very similar to sf::ConvexShape.
