问题 There is some diagrams of Yampa switches at: http://www.haskell.org/haskellwiki/Yampa/switch http://www.haskell.org/haskellwiki/Yampa/rSwitch http://www.haskell.org/haskellwiki/Yampa/kSwitch (and so on). I've found that the switch , the only one diagram with description, is the easiest one to get understand. The others seems hard to follow the similar symbols to read the diagrams. For example, to try to read the rSwitch with the symbols used in the switch may be: Be a recursive SF which is

问题 I'm stuck with generating debug output for my game objects using Haskell/Yampa (=Arrows) (with HOOD). My engine basically runs a list of game objects which produce Output states (line, circle) which are then rendered. data Output = Circle Position2 Double | Line Vector2 output :: [Output] -> IO () output oos = mapM render oos render :: Output -> IO () render (Circle p r) = drawCircle p r render (Line vec) = drawLine (Point2 0 0) vec The player object just moves to the right and is represented

Start with an initial SF of the same
