what is the self parameter mean in connect?

SIsilicon28

target_node is the node that will respond to the signal (first argument) and call its function (third argument).

self is an arbitrary variable. You could use any other variable that is a node.

oldSkool

no, target_node is the second argument

oldSkool

<source_node>.connect(<signal_name>, <target_node>, <target_function_name>)

@oldSkool said: so with the script attaching to the button, how do i get it to work?

Well first, your calling connect from yourself, so there's no need for a . before the function. Secondly, the second argument should be self, because the method in the third argument is owned by the script, i.e. self.

connect("button_pressed", self, "_on_button_pressed")

@oldSkool said: no, target_node is the second argument

Yes that's right. I never said otherwise.

oldSkool

this work just fine. what do i need to change to have it to work when i attach the script to the button?

I already gave you the answer.

oldSkool

so basically the second argument will always be self

SIsilicon28

@SIsilicon28 said: You use self if you want to reference the node with the script you are in, and $NodePath for any other nodes in the scene you want to reference. In this case, Button is the one with script so self would be used to reference it. The node path should be relative to self, so to reference label for instance, you'd have to do $"../label".

And as I explained previously, the second argument would be the node that has the method (third argument). If the method were outside this script, the second argument would be the node that has the script, which won't always be self.

But in your case, it will stay self as long as the method _performAction is in the same script as the connect function.

oldSkool

still not working. the script to the panel is disable

oldSkool

so $NodePath equal $nodeOfNodeInScene

oldSkool

i mean nodeInScene

oldSkool

if my script is attach to button or panel then i still use self. is this correct?

Megalomaniak

If the third thing in the argument is in the same script as that connect function then yes the second argument is self.

SIsilicon28

@oldSkool said: still not working. the script to the panel is disable

That's because the path to the label is wrong.

oldSkool

i establish that self refer to this so in my case it the panel

can you explain why it not working and how to fix it

scene tree structure Panel label Button

i attach this script to the button but it does not work

extends Button

func ready(): connect('pressed', self, 'performAction')

func _performAction():
	$label.text='hey everyone!'

oldSkool

how do i fix the label path

SIsilicon28

I showed you the path in one of my comments, remember? $"../label"

cybereality

Well, label is not a child of button, so you can't access it like that. You can try:

$"../label".text = "hopefully working"

SIsilicon28

@cybereality might wanna surround the node path with quotation marks there. :P
