hi i tried to make a tetris polygon
the FLIPPED L shape and this is what i get
http://imageshack.us/photo/my-images/38/goodab.gif
if you see the points are inserted in the right order
top left
top right
bottom right
bottom middle
middle middle
middle left
for some reason the shape is all messed up
any ideas? debugging showed the points are inserted well and i HAVE NO CLUE!
thanks!

Your shape is not
convex
, you cannot use SFML shape classes.

It's written in the
documentation
...
Btw if you don't want to write your own class, the
Thor
library has already one.
