(摘) Godot浮动文字

主场景中，鼠标左键点击则出现浮动文字

浮动文字场景：

代码:

extends Node2D

@export var text :String
@export var velocity = Vector2.ZERO
@export var gravity = Vector2.ZERO
@export var mass = 100

func _ready():
	var tween = create_tween()
	#tween.tween_property($Label,"modulate",Color($Label.modulate.r,$Label.modulate.g,$Label.modulate.b,0),1.0)
	$Label.scale = Vector2(0,0)
	$Label.text = text 
	tween.tween_property($Label,"scale",Vector2(1.0,1.0),1.0)
	tween.tween_property($Label,"scale",Vector2(0.0,0.0),1.0).set_delay(0.8)
	tween.connect("finished",onTweenFinished)

func _process(delta):
	velocity += gravity * mass * delta
	position += velocity * delta

func onTweenFinished():
	queue_free()

主场景代码：

extends Node2D

var float_text = preload("res://float.tscn")

func _input(event):
	if event is InputEventMouseButton and event.is_pressed():
		var ft = float_text.instantiate()
		ft.text = str(randi() % 100 -50)
		ft.velocity = Vector2(randf_range(-50,50),-100)
		ft.gravity = Vector2(0,1.3)
		ft.mass = 100
		ft.modulate = Color(randf_range(0.7,1.0),randf_range(0.7,1.0),randf_range(0.7,1.0),1.0)
		ft.position = event.position
		add_child(ft)

在主场景中稍作修改，把子场景中注释掉的渐隐加到主场景中，效果更自然一点：

extends Node2D

var float_text = preload("res://float.tscn")

func _input(event):
	if event is InputEventMouseButton and event.is_pressed():
		var tween = create_tween()
		var ft = float_text.instantiate()
		ft.text = str(randi() % 100 -50)
		ft.velocity = Vector2(randf_range(-50,50),-100)
		ft.gravity = Vector2(0,1.3)
		ft.mass = 100
		ft.modulate = Color(randf_range(0.7,1.0),randf_range(0.7,1.0),randf_range(0.7,1.0),1.0)
		ft.position = event.position
		tween.tween_property(ft,"modulate",Color(ft.modulate.r,ft.modulate.g,ft.modulate.b,0.1),2.0)
		add_child(ft)
