Godot Common questions Why would you use onready var versus regular var ? var is assigned when the script instance is created, if this is a node then it might not be added to the tree yet, so you can't use get_parent and similar on it. onready var is a shortcut for assigning vars in _ready() and is assigned a value after a node and siblings enter the tree. Only useful for nodes. Reference Troubleshooting A connected event is not receiving the emitted signal Make sure the handler is accepting the same number of arguments. For example if the emitted signal adds a context argument, then the connected handler must also accept the context argument, otherwise it is never called. extends Node2D func handle_mytrigger(): # never reached as we are not accepting the argument! print('nope') func _ready(): Events.connect("mytrigger", self, "handle_mytrigger") var myplayer = 'me' Events.emit_signal('mytrigger', myplayer)
