### Camera - New Features, Updates and Fixes
|
||||
|
||||
* All of the 2D Camera classes are now 100% covered by JSDocs!
|
||||
* `Camera.alpha` (and its related method `Camera.setAlpha`) allows you to set an alpha level for the entire camera. This impacts everything it is rendering, even if those objects also have their own alpha values too. You can tween the property to make the camera contents fade in / out, or otherwise set it as needed in your game.
|
||||
* `Camera.deadzone` (and its related method `Camera.setDeadzone`) allows you to specify the deadzone for a camera. The deadzone is a rectangular region used when a camera is following a target. If the target is within the deadzone then the camera will not scroll. As soon as the target leaves the deadzone, the camera will begin tracking it (applying lerp if needed.) It allows you to set a region of the camera in which a player can move freely before tracking begins. The deadzone is re-centered on the camera mid point every frame, meaning you can also use the rectangle for other in-game chcecks as needed.
|
||||
* `Camera.pan` is a new Camera Effect that allows you to control automatic camera pans between points in your game world. You can specify a duration and ease type for the pan, and it'll emit events just like all other camera effects, so you can hook into the start, update and completion of the pan. See the examples and docs for more details.
|
||||
* `Camera.zoom` is a new Camera Effect that allows you to control automatic camera zooming. You can specify a duration and ease type for the zoom, as well as the zoom factor of course, and it'll emit events just like all other camera effects, so you can hook into the start, update and completion of the zoom. Used in combination with the new Pan effect you can zoom and pan around with ease. See the examples and docs for more details.
|
||||
* `Camera.midPoint` is a new Vec2 property that is updated every frame. Use it to obtain exactly where in the world the center of the camera is currently looking.
|
||||
* `Camera.displayWidth` is a new property that returns the display width of the camera, factoring in the current zoom level.
|
||||
* `Camera.displayHeight` is a new property that returns the display height of the camera, factoring in the current zoom level.

|
||||
* The Camera Manager is a plugin that belongs to a Scene and is responsible for managing all of the Scene Cameras.
|
||||
*
|
||||
* By default you can access the Camera Manager from within a Scene using `this.cameras`, although this can be changed
|
||||
* in your game config.
|
||||
*
|
||||
* The Camera Manager can manage up to 31 unique Cameras. You can use the properties `camera1` through to `camera10`
|
||||
* for quick and easy access to the first 10 cameras you define.
|
||||
*
|
||||
* Create new Cameras using the `add` method. Or extend the Camera class with your own addition code and then add
|
||||
* the new Camera in using the `addExisting` method.
|
||||
*
|
||||
* Cameras provide a view into your game world, and can be positioned, rotated, zoomed and scrolled accordingly.
|
||||
*
|
||||
* A Camera consists of two elements: The viewport and the scroll values.
|
||||
*
|
||||
* The viewport is the physical position and size of the Camera within your game. Cameras, by default, are
|
||||
* created the same size as your game, but their position and size can be set to anything. This means if you
|
||||
* wanted to create a camera that was 320x200 in size, positioned in the bottom-right corner of your game,
|
||||
* you'd adjust the viewport to do that (using methods like `setViewport` and `setSize`).
|
||||
*
|
||||
* If you wish to change where the Camera is looking in your game, then you scroll it. You can do this
|
||||
* via the properties `scrollX` and `scrollY` or the method `setScroll`. Scrolling has no impact on the
|
||||
* viewport, and changing the viewport has no impact on the scrolling.
|
||||
*
|
||||
* By default a Camera will render all Game Objects it can see. You can change this using the `ignore` method,
|
||||
* allowing you to filter Game Objects out on a per-Camera basis.
|
||||
*
|
||||
* A Camera also has built-in special effects including Fade, Flash and Camera Shake.
