Random beginner-question: animate a single character within a label

Hi everyone,

I wonder how I could have a single character in a text within a label to be animated under one certain circumstance.

I have a RichTextLabel connected to some number- and a comma-button. Only one comma is possible, so entering one makes the comma-button “inactive”… it still registers tapping though, so in my func _on_Button_button_comma_pressed_while_disabled(): I can apply all kinds of “there’s-already-a-comma-written!”-reactions (like e. g. a rapidly blinking cursor).

Now I’d like the comma itself in the text to blink a couple of times when that function is triggered. Could I somehow find(‘,’) or get(“,”) and then maybe apply some Tween-animation or even bbcode? Or is there an easier way I just can’t think of?

Hey there, yes you could! let me elaborate!

lets assume you have some code like:

onready var my_rich_text_label = $Rich_Text_Label

then in your function you could have

_on_Button_button_comma_pressed_while_disabled():
        text = my_rich_text_label.bbcode_text
        text.replace(",","[custom_bbcode_tag],[/custom_bbcode_tag]")
        #maybe then wait a little bit and replace back the comma so the animation stops

you’ll have to implement your custom bbcode tag, i suggest reading the documentation on that subject

i dont think there is any built in function to do it, but you can create your own system using replace(text, ",", " ") to create the blink effect (replace , with an empty space), linked to a timer that will repeat this action a couple of time

Hi Andrea and astrale,

thanks for your suggestions, I’m sure this is exactly what I’m looking for. The visible mentioned in the docs will be what I’m aiming at.

I already have several bbcode working in my RichTextLabel, including var templateAlwaysAllRight = "[right][color=blue]{alwaysAllRight}[/color][/right]" for some alignment. Now, when I’m adding e. g. text.replace(",","[color=green],[/color]"), entering 1,2 and then tapping the disabled , again, it leads to [right][color=blue]1,2[/color][/right] being displayd as text in my RichTextLabel…

This is about as far as my beginner-understanding goes at this point, so I wonder (and guess): two “separate” bbcodes can’t apply to the same object? So would I need to have them both combined in one? Or am I missing something else?

EDIT:
The docs describe in Custom BBCode tags (e. g.)

var bbcode = "ghost"

func _process_custom_fx(char_fx):
...

that can then be used as [ghost] ... [/ghost], but I don’t see how ghost is connected to the function (so how ghost would “know” its own variables). So I wonder how I can make [ghost],[/ghost] work (as [custom_bbcode_tag] in your example)?
