Graphics.Gloss.Interface.IO.Simulate
Description
Simulate mode is for producing an animation of some model who's picture
changes over finite time steps. The behavior of the model can also depent
on the current ViewPort.
- module Graphics.Gloss.Data.Display
- module Graphics.Gloss.Data.Picture
- module Graphics.Gloss.Data.Color
- simulateIO :: forall model. Display -> Color -> Int -> model -> (model -> IO Picture) -> (ViewPort -> Float -> model -> IO model) -> IO ()
- data ViewPort = ViewPort {
- viewPortTranslate :: !(Float, Float)
- viewPortRotate :: !Float
- viewPortScale :: !Float

Arguments
| :: Display | Display mode. |
| -> Color | Background color. |
| -> Int | Number of simulation steps to take for each second of real time. |
| -> model | The initial model. |
| -> (model -> IO Picture) | A function to convert the model to a picture. |
| -> (ViewPort -> Float -> model -> IO model) | A function to step the model one iteration. It is passed the current viewport and the amount of time for this simulation step (in seconds). |
| -> IO () |
The ViewPort represents the global transformation applied to the displayed picture.
When the user pans, zooms, or rotates the display then this changes the ViewPort.
