You should destroy any resources that may be in use by your Scene in this event handler.

Parameters:

name	type	description
sys	Phaser.Scenes.Systems	A reference to the Scene Systems class of the Scene that emitted this event.

PAUSE

Description:

The Scene Systems Pause Event.

This event is dispatched by a Scene when it is paused, either directly via the pause method, or as an action from another Scene.

POST_UPDATE

Description:

The Scene Systems Post Update Event.

This event is dispatched by a Scene during the main game loop step.

The event flow for a single step of a Scene is as follows:

1. PRE_UPDATE
2. UPDATE
3. The Scene.update method is called, if it exists
4. POST_UPDATE
5. RENDER

Listen to it from a Scene using this.scene.events.on('postupdate', listener).

A Scene will only run its step if it is active.

Parameters:

name	type	description
sys	Phaser.Scenes.Systems	A reference to the Scene Systems class of the Scene that emitted this event.
time	number	The current time. Either a High Resolution Timer value if it comes from Request Animation Frame, or Date.now if using SetTimeout.
delta	number	The delta time in ms since the last frame. This is a smoothed and capped value based on the FPS rate.

PRE_UPDATE

The Scene Systems Pre Update Event.

This event is dispatched by a Scene during the main game loop step.

The event flow for a single step of a Scene is as follows:

1. PRE_UPDATE
2. UPDATE
3. The Scene.update method is called, if it exists
4. POST_UPDATE
5. RENDER

Listen to it from a Scene using this.scene.events.on('preupdate', listener).

A Scene will only run its step if it is active.

Parameters:

name	type	description
sys	Phaser.Scenes.Systems	A reference to the Scene Systems class of the Scene that emitted this event.

delta	number	The delta time in ms since the last frame. This is a smoothed and capped value based on the FPS rate.

READY

Description:

The Scene Systems Ready Event.

This event is dispatched by a Scene during the Scene Systems start process. By this point in the process the Scene is now fully active and rendering. This event is meant for your game code to use, as all plugins have responded to the earlier 'start' event.

Listen to it from a Scene using this.scene.events.on('ready', listener).

Parameters:

name	type	arguments	description
sys	Phaser.Scenes.Systems		A reference to the Scene Systems class of the Scene that emitted this event.
data	any	<optional>	An optional data object that was passed to this Scene when it was started.

Listen for it from a Scene using this.scene.events.on('removedfromscene', listener).

Parameters:

RENDER

Description:

The Scene Systems Render Event.

This event is dispatched by a Scene during the main game loop step.

The event flow for a single step of a Scene is as follows:

1. PRE_UPDATE
2. UPDATE
3. The Scene.update method is called, if it exists
4. POST_UPDATE
5. RENDER

Listen to it from a Scene using this.scene.events.on('render', listener).

You should free-up any resources that may be in use by your Scene in this event handler, on the understanding that the Scene may, at any time, become active again. A shutdown Scene is not 'destroyed', it's simply not currently active. Use the DESTROY event to completely clear resources.
