Methods
-
add(key, state, autoStart)
-
Adds a new State into the StateManager. You must give each State a unique key by which you'll identify it. The State can be either a Phaser.State object (or an object that extends it), a plain JavaScript object or a function. If a function is given a new state object will be created by calling it.
Parameters:
Name Type Argument Default Description keystring A unique key you use to reference this state, i.e. "MainMenu", "Level1".
statePhaser.State | object | function The state you want to switch to.
autoStartboolean <optional>
false If true the State will be started immediately after adding it.

checkState(key) → {boolean}

Parameters:
Name Type Description keystring The key of the state you want to check.
- Source:
Returns:
true if the State has the required functions, otherwise false.
- Type
- boolean

destroy()

Removes all StateManager callback references to the State object, nulls the game reference and clears the States object. You don't recover from this without rebuilding the Phaser instance again.

Restarts the current State. State.shutDown will be called (if it exists) before the State is restarted.
