Graphics.UI.FreeGame

This module just re-exports other submodules.

Main

type Game = F GUI

Game is a free monad which describes GUIs. This monad is an instance of Picture2D so you can construct it using fromBitmap and can be transformed with translate, scale, rotate, colored.

It is also an instance of Keyboard and Mouse. Note that mousePosition returns a relative position. For example:

 foo = foreverTick $ do
   p <- mousePosition
   translate p $ colored blue $ polygonOutline [V2 (-8) (-8), V2 8 (-8), V2 8 8, V2 (-8) 8]

When we run foo using runGame, a blue square follows the cursor. And translate (V2 240 240) foo, rotate 45 foo, scale 1.5 foo also does in the same way.

You have to call tick at the end of the frame.

The only way to embody a Game as a real stuff is to apply runGame.
