The “:?>” operator performs a dynamic cast, which means that the success of the cast is determined at run time. ”:?>” downcast - it will cast Object to Something. If I have some class that inherits the System.Object ( Default behavior in. IsOpen () with | true -> mainLoop () |> ignore | false -> () mainLoop () 0Ĭouple of interesting things in this code. Close ()) let rec mainLoop () = mainWindow. AddHandler ( fun sender args -> ( sender :?> RenderWindow ). let main argv = let mainWindow = new RenderWindow ( new VideoMode ( 600u l, 600u l ), "EmptySpace" ) mainWindow. To start with something, I have decided to do my first simple game loop and render window. I have heard about monads and how you can manage state with them, but still its going to be difficult for apprentice like me. I am a little worried about its stateless world. I really like the way it’s done in Cataclysm DDA, so I ll try to emulate it.Īpart from coding the game and its logic, the most difficult part will be to use F#. At the beginning I am mostly going to focus on 2D tile rendering and some ray casting to calculate field of view. In the past I have been using SDL wrapper which was also fine. It’s quite good and I know a bit about it. You know symbols, characters, letters and some simple graphic, just like in old MUD games.įor graphic layer, I am going to use SFML and it’s. That’s why I have started to code one game idea that was following me for some time.īecause I don’t care about the graphics but the game-play, the graphic I am going to use will be an ASCII styles tile set. The best way to learn new language is to do some project.
