godot 4 全局自定义信号，发射信号并携带参数

1. 全局信号

extends Node

# 定义确实移动参数
signal character_move(dest_position:Vector2)

2. 角色处理

extends CharacterBody2D


@export var speed:int = 100


func _ready():
	GlobalSignal.connect("character_move", move)


func _physics_process(_delta):
	move_and_slide()


func move(dest_position:Vector2):
	if position.distance_to(dest_position) > 3 :
		var direction = position.direction_to(dest_position)
		velocity = direction * speed
	else:
		velocity = Vector2()

3. 发射自定义信号，并携带参数

extends Node2D

@onready var character1 = $character1
@onready var character2 = $character2

func _ready():
	pass 


func _process(_delta):
	pass


func _on_button_1_pressed():
	GlobalSignal.character_move.emit(character2.position)


func _on_button_2_pressed():
	GlobalSignal.character_move.emit(character1.position)
