Constructor

Phaser. SignalBinding

new SignalBinding(signal, listener, isOnce, listenerContext, priority, args)

Parameters

Reference to Signal object that listener is currently bound to.

listener function

Handler function bound to the signal.

isOnce boolean

priority number <optional>

The priority level of the event listener. (default = 0).

args any <optional>
<repeatable>
(none)

Additional arguments to pass to the callback (listener) function. They will be appended after any arguments usually dispatched.

Detach binding from signal. alias to: @see mySignal.remove(myBinding.getListener());

Returns
function | null -

Handler function bound to the signal or null if binding was previously detached.
