Question
I’m trying to do a dialogue system by my own because i don’t understand how to use the dialogue systems addons of the community, they are kind of hard to implement in a project (at least for me 
).
My idea of how to make that dialogue system is by a CSV file that has the character name and the dialog text (I’ll make a CSV per scene, environment, action, whatever) and by that get all the information that i need for the dialogue.
So, I’m having a problem on these lines:
if !_dialogue_file == null:
if _i < dialog_data.size():
character = dialog_data[_i]["Character"]
dialogue = dialog_data[_i]["Dialogue"]
var _dialogue = dialogue.replace("'","")
character_name_text.text = character
dialogue_label.bbcode_text = _dialogue
finished_dialogue = false
if Input.is_action_just_pressed("Interact"):
if finished_typing:
_i += 1
if !interact_key_was_pressed:
dialogue_label.percent_visible = 0
start_typing_delay.start()
elif _i == dialog_data.size():
finished_dialogue = true
my idea is to say that finished_dialog is true when _i has the same value as the one returned by dialog_data.size() (5 in my case) but as in programming zero is a valid number then it triggers the problem that the dialog is supposed to be finished but according to elif it is not like that (that is to say that when _i is four the dialog should be finished), since the CSV file has four lines (discarding the one that says “Character, Dialogue” ) and my idea is that when _i is four finished_dialog is true.
Btw, here is the whole code of the dialogue system in case if you want to review it
