Methods

draw :: (forall f. (Applicative f, Monad f, Picture2D f, Local f) => f a) -> m a

Draw an action that consist of Picture2D's methods.

preloadBitmap :: Bitmap -> m ()

Load a Bitmap to avoid the cost of the first invocation of bitmap.

bracket :: Frame a -> m a

Run a Frame, and release all the matter happened.

forkFrame :: Frame () -> m ()

Run a Frame action concurrently. Do not use this function to draw pictures.

takeScreenshot :: m Bitmap

Generate a Bitmap from the front buffer.

setFPS :: Int -> m ()

Set the goal FPS.

setTitle :: String -> m ()

showCursor :: m ()

hideCursor :: m ()

clearColor :: Color -> m ()

getFPS :: m Int

Get the actual FPS value.

getBoundingBox :: m BoundingBox2

setBoundingBox :: BoundingBox2 -> m ()
