/* 2D camera that defines what region is shown on screen
|
||||
*
|
||||
* sf::View defines a camera in the 2D scene.
|
||||
*
|
||||
* This is a very powerful concept: you can scroll, rotate or zoom the entire scene without altering the way that your
|
||||
* drawable objects are drawn.
|
||||
*
|
||||
* A view is composed of a source rectangle, which defines what part of the 2D scene is shown, and a target viewport,
|
||||
* which defines where the contents of the source rectangle will be displayed on the render target
|
||||
* (window or render-image).
|
||||
*
|
||||
* The viewport allows to map the scene to a custom part of the render target, and can be used for split-screen or
|
||||
* for displaying a minimap, for example. If the source rectangle has not the same size as the viewport, its contents
|
||||
* will be stretched to fit in.
|
||||
*
|
||||
* To apply a view, you have to assign it to the render target. Then, every objects drawn in this render target will
|
||||
* be affected by the view until you use another view.
|
||||
*
|
||||
* Usage example:
|
||||
*
|
||||
* window = SFML::RenderWindow.new
|
||||
* view = SFML::View.new
|
||||
*
|
||||
* # Initialize the view to a rectangle located at (100, 100) and with a size of 400x200
|
||||
* view.reset( [100.0, 100.0, 400.0, 200.0] )
|
||||
*
|
||||
* # Rotate it by 45 degrees
|
||||
* view.rotate( 45 )
|
||||
*
|
||||
* # Set its target viewport to be half of the window
|
||||
* view.viewport = [0.0, 0.0, 0.5, 1.0 ]
|
||||
*
|
||||
* # Apply it
|
||||
* window.view = view
|
||||
*
|
||||
* # Render stuff
|
||||
* window.draw( someSprite )
|
||||
*
|
||||
* # Set the default view back
|
||||
* window.view = window.defaultView
|
||||
*
|
||||
* # Render stuff not affected by the view
|
||||
* window.draw( someText )
