data GlossVars

The concurrent variables needed to communicate with the gloss thread.

Constructors

GlossVars

Fields

• glossEventsRef :: IORef [Event]

  Stores all Events that arrived since the last tick

• glossPicRef :: IORef Picture

  Stores the next Picture to be painted

• glossDTimeVar :: MVar Float

  Stores the time passed since the last tick

• glossExitRef :: IORef Bool

data GlossHandle

In a Handle, store a separate thread where the gloss main loop is executed, and several concurrent variables to communicate with it.

Constructors

GlossHandle

Fields

• glossThread :: ThreadId
• glossVars :: GlossVars

defaultSettings :: GlossSettings

glossHandle :: GlossSettings -> Handle IO GlossHandle

Will create a handle for communication with the gloss thread, and start gloss.

getPicture :: GlossVars -> IO Picture

handleEvent :: Bool -> Event -> GlossVars -> IO GlossVars

stepGloss :: Float -> GlossVars -> IO GlossVars

glossWrapC :: GlossSettings -> Cell PictureM a b -> Cell (StateT (HandlingState IO) IO) a b

Given a cell in the gloss monad PictureM, start the gloss backend and connect the cell to it. This introduces Handles, which need to be taken care of by calling runHandlingState or a similar function.
