reactimate-game is a library for reactimate which implements some common functionality for simple 2D games.
There are some examples in the examples folder. Check them out for a quickstart into the library.
Rendering is done with the render signal which renders the given Picture with the Camera to the screen. The following example renders a red rectangle in the bottom left corner of the screen.
import Reactimate
import Reactimate.Game
import qualified Data.Vector.Storable as VS
import Data.Colour.Names
main :: IO ()
main =
reactimate $
limitSampleRate 60 $
setupGame (GameConfig "Basic Example" defaultWindow) $ \gameEnv ->
constant (Camera (V2 0 0) (V2 800 600), picture) >>> render gameEnv >>> constant Nothing
picture :: Picture
picture = makePicture 0 $ drawRectangle (packColour red) $ Rectangle (V2 0 0) (V2 500 300)
