The first version of XUI2D and the X2 framework are almost ready. Joints are now being added.
The joints feature is a very powerful feature of box2d and can be used to implement complicated physical structures.
X2TileMap was also improved and it now properly supports rotated objects.
There is almost no code in the above example except of the template code.
The objects are defined with Tiled editor:
This code adds the joints between the elements based on the "hinge" objects positions:
