Game
The Phaser.Game instance is the main controller for the entire Phaser game. It is responsible
for handling the boot process, parsing the configuration values, creating the renderer,
and setting-up all of the global Phaser systems, such as sound and input.
Once that is complete it will start the Scene Manager and then begin the main game loop.
You should generally avoid accessing any of the systems created by Game, and instead use those
made available to you via the Phaser.Scene Systems class instead.

Public Methods
boot
<instance> boot()
Description:
This method is called automatically when the DOM is ready. It is responsible for creating the renderer,
displaying the Debug Header, adding the game canvas to the DOM and emitting the 'boot' event.
It listens for a 'ready' event from the base systems and once received it will call Game.start.
Access: protected
Fires: Phaser.Core.Events#event:BOOT
Source: src/core/Game.js#L339
Since: 3.0.0
destroy
<instance> destroy(removeCanvas, [noReturn])
Description:
Flags this Game instance as needing to be destroyed on the next frame, making this an asynchronous operation.
It will wait until the current frame has completed and then call runDestroy internally.
If you need to react to the games eventual destruction, listen for the DESTROY event.
If you do not need to run Phaser again on the same web page you can set the noReturn argument to true and it will free-up
memory being held by the core Phaser plugins. If you do need to create another game instance on the same page, leave this as false.
Parameters:
| name | type | optional | default | description |
|---|---|---|---|---|
| removeCanvas | boolean | No | Set to true if you would like the parent canvas element removed from the DOM, or false to leave it in place. | |
| noReturn | boolean | Yes | false | If true all the core Phaser plugins are destroyed. You cannot create another instance of Phaser on the same web page if you do this. |

headlessStep
<instance> headlessStep(time, delta)
Description:
A special version of the Game Step for the HEADLESS renderer only.

Request Animation Frame, or Set Timeout on very old browsers.)
The step will update the global managers first, then proceed to update each Scene in turn, via the Scene Manager.
This process emits prerender and postrender events, even though nothing actually displays.
Parameters:
| name | type | optional | description |
|---|---|---|---|
| time | number | No | The current time. Either a High Resolution Timer value if it comes from Request Animation Frame, or Date.now if using SetTimeout. |
| delta | number | No | The delta time in ms since the last frame. This is a smoothed and capped value based on the FPS rate. |
