| * Author: James Skemp ( jamesrskemp.com / strivinglife.com / github.com/JamesSkemp ), based upon libGDX 1.6.2. | |

| * This orthographic camera controller will handle both inputs and gestures, and can log when it's triggered. | |
| * | |
| * Usage example: | |
| camera = new OrthographicCamera(); | |
| camera.setToOrtho(false, Constants.VIEWPORT_GUI_WIDTH, Constants.VIEWPORT_GUI_HEIGHT); | |
| camera.update(); | |
| cameraController = new OrthographicCameraController(camera); | |
| // Handle inputs. | |
| InputMultiplexer inputMultiplexer = new InputMultiplexer(); | |
| // TODO add any game-related actions you want to handle before the camera. | |
| inputMultiplexer.addProcessor(new GestureDetector(cameraController)); | |
| inputMultiplexer.addProcessor(cameraController); | |
| Gdx.input.setInputProcessor(inputMultiplexer); | |
