 				Called when the node is "ready", i.e. when both the node and its children have entered the scene tree. If the node has children, their [method _ready] callbacks get triggered first, and the parent node will receive the ready notification afterwards.

+				Corresponds to the [constant NOTIFICATION_READY] notification in [method Object._notification]. See also the [code]@onready[/code] annotation for variables.
 				Usually used for initialization. For even earlier initialization, [method Object._init] may be used. See also [method _enter_tree].
 				[b]Note:[/b] [method _ready] may be called only once for each node. After removing a node from the scene tree and adding again, [code]_ready[/code] will not be called for the second time. This can be bypassed with requesting another call with [method request_ready], which may be called anywhere before adding the node again.
