Asked By | Myrmex |
I have an event log with occasional choices created with push_meta() method but the tag isn’t closed after buttons are displayed causing all the following text to be clickable.
Can it be solved without switching to bbcode_text display?
Can you provide your code?

Project is just a Control node with RichTextLabel child.
# ==============================
extends Control
# ==============================
onready var Text = $RichTextLabel
var execute # Calls method and stores its state
var choice # Stores value when player makes decision
# ==============================
func _ready():
Text.connect("meta_clicked", self, "ReadMeta") # If [meta] text is clicked
AddLine("Testing123")
execute = Scenario_A() # Print text sequence with options
# ===============================
func Scenario_A():
AddLine("All systems OK")
AddLine("Click a button:")
AddForm("A", "[ Option A ]", Color(.6,1,.6)) # Draw button with value "A"
AddForm("B", "[ Option B ]", Color(1,.6,.6)) # Draw button with value "B"
AddLine() # Newline
yield() # Freeze sequence until any button is pressed
# Method is resumed here with picked choice stored in global variable
AddLine(str("Option ", choice, " picked"))
yield(get_tree().create_timer(.3), "timeout")
AddLine("Regular text")
yield(get_tree().create_timer(.3), "timeout")
AddLine("Regular text")
# ==============================
# Print plain text and newline
func AddLine(text="", color=Color.white, style=0):
if !color: color = Color.white # Allows calling method with null arg
Text.push_color(color)
if style in [1, 3]: Text.push_italics()
if style in [2, 3]: Text.push_bold()
Text.add_text(str(text, "\n"))
# ==============================
# Print interactive text
func AddForm(respond=null, text="", color=Color.white, _style=0):
if !color: color = Color.white # Allows calling method with null arg
Text.push_color(color)
Text.push_meta(respond) # Assign custom value to button
Text.add_text(text)
# !!! >>>>> [meta] tag must be closed here <<<<< !!!
# ==============================
func ReadMeta(meta): # Pass picked button's value to global variable
choice = meta
ResumeMethod()
# ==============================
func ResumeMethod(): # Continue stored method from it's current state
if !execute: # Button pressed but no method to pass it to
AddLine("Unexpected function call", Color.red)
return
execute.resume() # Proceed with scenario
execute = null
choice = null

Did You find the answer ?

Yeah, checking this code years later reveals an obvious lack of Text.pop() call after text is added to clear the meta tag. Just tested it, works fine.
Myrmex | 2023-02-08 21:08
How do I use it ?
I thouth it should work like this :
push_meta(Node)
append_bbcode(text)
pop()
append_bbcode(unhyperlinkedtext)
But it still hyperlinks everything. I tried to place pop() in almost every place of this code and it doesn’t do it… please help

pop() closes the most recent tag so if you call append_bbcode() after the meta it becomes the last one. In theory, you could simply use two pops but, according to the docs, append_bbcode() is working in a different way so you might consider using other methods.

Man, this Label shit is unusable. Even with other methods, adding bbcode manually, it is just impossible to close a tag of metadata containing a real reference to a node. I had to give up.
