class Scar::Objects::Camera

Overview

A camera takes care of calling render() functions and drawing drawables.

A camera is essentially a wrapper around and SF::View. Its instance methods are delegated, so you can use them as normal instance methods. When drawing Entitys or Objects, their transforms are applied automatically.

Each space has a default camera, so there is no need to use this class explicitly in your application, except if you need custom views. See the CrSFML documentation for that.

def render_view(app, space, dt) #

This method is called by the render method of Spaces

It calls all render methods and draws all drawables onto the screen.
