Getting a Rich text label to add additional text.

damius

I am gonna say it now, I'm really new to Godot, I understand the basics of coding, but I am really new to it all. Right now I'm trying to kinda learn things on my own. I've managed to create a button and a Dialogue box. I want the button to delete the text that started off in the richtextlabel. And then add text after that. Right now, my script for the button says:

extends TextureButton

func _ready():
	var button = Button.new()
	button.text = "Click me"
	button.connect  ("pressed",self, "_button_pressed")
	add_child(button)

func _button_pressed():
	print("Hello world!")

And the script for the dialogue box says: 
extends RichTextLabel

func _ready():
	add_text ("Hi I am new.")

func _on_StartButton_pressed():
	clear()
	add_text("Like really really new")

Right now the button basically does nothing aside from printing hello world when pressed.

The property is called "text" same as the button. You can set it to whatever you want. https://docs.godotengine.org/en/stable/classes/class_richtextlabel.html

Always good to check the documentation to see what is available.

Also, if you want to post code on the forum, use the code button (under the quote button) or write 3 tildes on a line by itself directly above and directly below the code "~~~" (without quotes).

Gotcha, may I ask why in this case add_text wouldn't work? I did, I just still didn't quite understand ^{^;} So right now this is what it looks like.


func _on_StartButton_pressed():
	clear()
	RichTextLabel.text = "Like really really new"

I still can't get it change what's in the RichTextLabel

What happens if you change: RichTextLabel.text = "Like really really new" to: RichTextLabel.bbcode_text = "Like really really new"

RichTextLabel.text is a property that holds a string value, while RichTextLabel.add_text() is a method that, according to the docs "Adds raw non-BBCode-parsed text to the tag stack.": https://docs.godotengine.org/en/stable/classes/class_richtextlabel.html#class-richtextlabel-method-add-text

I've always used the text property rather than the method so I'm not sure what they mean there by "tag stack" but I'm sure it has some specific meaning here.

DaveTheCoder

I have only limited experience with RichTextLabel, and have only changed the text using the Inspector. I've found that changing the BBCode text property works, while changing the text property has no effect.

I have the BBCode enabled property set, in case that's relevant.

So in the case of doing this:

RichTextLabel.text = "Like really really new"

to:

RichTextLabel.bbcode_text = "Like really really new"

It did some weird things. For one I think it didn't recognize that the DialogueBox node existed, because the script is in the dialoguebox? I tried initializing it as a variable through

onready var DialogueBox =$DialogueBox

It wasn't able to find it. And thus crashed the debugging thing. Specifically saying Node Not found: "DialogueBox"

So instead I changed it to,

func _ready():
	bbcode_text= "Hello I am new"
	



func _on_StartButton_pressed():
	clear()
	bbcode_text = "Like really really new"

Which if I changed it to this, it did type "Hello I am new" But it still didn't change the text in the Dialogue Box. Would it be better if I just watched like a dialogue box tutorial for this instead and see if I can glean any any knowledge from it?

DaveTheCoder

The change I suggested was based on your variable RichTextLabel being a reference to a node that's of type RichTextLabel. Apparently that's not the case.

Doing the tutorial is probably a good idea.

This code makes no sense. Sorry, I didn't notice before:

RichTextLabel.text = "Like really really new"

RichTextLabel is a class, not an object. You can only change properties on an object (an instance of a class).

DaveTheCoder

Actually, you can declare a variable named RichTextLabel that's a reference to a RichTextLabel node, even though it's not a good idea.

I just tried it, and it works. I guess I assumed that's what he had done.
