My simple dialogue systemPurpleSunriseHello,
I wanted to share my dialogue system. It's much simpler than the reference.
Do you think it's valid? Is it too simple or error prone?
I created a resource:
```gdscript
class_name DialogueItem extends Resource
@export var emotion : Texture2D = null
@export var portrait : Texture2D = null
@export_multiline var text : String = ""
```
I created a UI scene for the dialogue box:
```gdscript
class_name DialogueBox extends Control
signal dialogue_finished
@onready var next_button: Button = %NextButton
@onready var text_label: Label = %TextLabel
@onready var npc_portrait: TextureRect = %NpcPortrait
@onready var npc_expression: TextureRect = %NpcExpression
@export var npc_dialogue : Array[DialogueItem] = []
var dialogue_idx : int = 0
func _ready() -> void:
hide()
next_button.pressed.connect(func()->void:
display_textbox(dialogue_idx)
)
func _input(event: InputEvent) -> void:
if event.is_action_pressed("interact") and next_button.disabled == false and visible == true:
next_button.emit_signal("pressed")
func display_textbox(index : int)->void:
if index == npc_dialogue.size():
hide()
emit_signal("dialogue_finished")
return
show()
next_button.disabled = true
text_label.text = npc_dialogue[index].text
npc_portrait.texture = npc_dialogue[index].portrait
npc_expression.texture = npc_dialogue[index].emotion
text_label.visible_ratio = 0.0
var printing_time := text_label.text.length() / 20.0
var tween := create_tween()
tween.tween_property(text_label,"visible_ratio", 1.0, printing_time)
await tween.finished
dialogue_idx += 1
next_button.disabled = false
```
Then I created a scene for Sophia NPC:
```gdscript
class_name Npc extends StaticBody2D
@onready var area_2d: Area2D = %Area2D
@onready var dialogue_box: DialogueBox = %DialogueBox
@export var dialogue : Array[DialogueItem] = []
var _player : Player = null
func _ready() -> void:
dialogue_box.npc_dialogue = dialogue
dialogue_box.dialogue_finished.connect(func()->void:
if _player != null:
_player.remove_control_from_player(false)
set_process_unhandled_input(true)
await get_tree().create_timer(0.2).timeout
dialogue_box.dialogue_idx = 0
)
area_2d.body_entered.connect(func(body : Node)->void:
if body is Player:
_player = body)
area_2d.body_exited.connect(func(body : Node)->void:
if body is Player:
_player = null)
func _unhandled_input(event: InputEvent) -> void:
if event.is_action_pressed("interact") and _player != null:
set_process_unhandled_input(false)
_player.remove_control_from_player(true)
dialogue_box.display_textbox(dialogue_box.dialogue_idx)
```
Is this too simple? Also I created a timer to let the dialogue box close before resetting the index. Is it bad way to do this? I didn't add sliding tweens etc but I think it wouldn't be a problem to add those features to this script right?
Thank you in advance! It was pretty fun!30Feb. 03, 2025
Code addition and one little issuePixAngelIf the player decides to leave after the conversation and then come back, I can't see in your code that the array is reset. Below it's how I solved it for me :
```gdscript
func _ready() -> void:
dialogue()
_next_button.pressed.connect(func()-> void:
dialogue_index += 1
if dialogue_index == dialogue_item.size():
dialogue_index = 0
dialogue()
EndDialogue.emit()
else:
dialogue()
)
```
Another issue is tweens effect are already read before talking to NPC for the first time. How to delay the reading of these tween knowing that the cause comes from the ready function. Can we instantiate the dialogue.tscn in a another way to solve it, or does it exist a method to delay tween effect?30Jan. 24, 2025
Error when showing the dialogue with the NPCram876Hello! I'm stuck at the stage where I need to bring up the NPC dialog box. The dialog itself works without errors, but when I start the dialog, I get an error that the dialog nodes do not exist. Here is my project. In my project, I used resources.30Jan. 11, 2025
can you solve this particle issue?Celsthe particles emit immediately when the scene starts even though that particle in inspectator is set to be false? is that bug in godot?30Jan. 01, 2025
