godot 如何生成 2d 子弹并同步多人游戏

Question

对于 godot，我正在尝试生成子弹，子弹生成工作正常，但我不知道如何将其联网，我尝试将其生成为玩家的兄弟姐妹和孩子，但我无法让它显示在所有内容中客户。

玩家代码：

extends CharacterBody2D

var health = 10

func _enter_tree():
    set_multiplayer_authority(str(name).to_int())
    
@onready var camera = %Camera2D
const SPEED = 330.0
const JUMP_VELOCITY = -400.0

# Get the gravity from the project settings to be synced with RigidBody nodes.
var gravity = ProjectSettings.get_setting("physics/2d/default_gravity")


func _physics_process(delta):
    if not is_multiplayer_authority(): camera.enabled = false
    if is_multiplayer_authority(): 
        if Input.is_action_pressed("use_shoot"):
            shoot()
        
    #if not is_multiplayer_authority(): return
    # Add the gravity.
    if not is_on_floor():
        velocity.y += gravity * delta

    # Handle jump.
    if is_multiplayer_authority(): 
        if Input.is_action_pressed("i_up") and is_on_floor():
            velocity.y = JUMP_VELOCITY

    # Get the input direction and handle the movement/deceleration.
    # As good practice, you should replace UI actions with custom gameplay actions.
        var direction = Input.get_axis("i_left", "i_right")
        if direction:
            velocity.x = direction * SPEED
        else:
            velocity.x = move_toward(velocity.x, 0, SPEED)
        move_and_slide()
                    
func take_damage(amount):
    print("YOUCH")
    print("YOUCH")
    health -= amount
    if health <= 0:
        queue_free()
        
@rpc()
func shoot():
    var bullet = preload("res://scenes/bullet.tscn").instantiate()
    add_child(bullet)
    bullet.rotation = bullet.global_position.angle_to_point(get_global_mouse_position())
    bullet.rotation_degrees += -90


func _on_area_2d_body_entered(body):
    if body.is_in_group("Arbullet"):
        queue_free()

项目符号代码：

extends Area2D

var speed = -560
# Called when the node enters the scene tree for the first time.
func _ready():
    pass # Replace with function body.


# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta):
    position += transform.x * speed * delta


func _on_body_entered(_body):
    #if body.is_in_group("player"):
        #body.take_damage(1)
    #queue_free()
    pass

嗯，是的，我想不出一个合理的方法来产生子弹，如果可以的话，请找到一种方法，这样我就不会伤害产生子弹的人。谢谢！

为了在网络上共享实例化场景，需要将这些场景添加到 MultiplayerSpawner 节点。

就您而言，这很简单

1. 将 MultiplayerSpawner 节点添加到您的游戏场景。
2. 将您的子弹场景添加到 MultiplayerSpawner 的 AutoSpawnList 中。
3. 将 MultiplayerSpawner 的 SpawnPath 变量设置为将成为生成场景的父节点的节点（生成子弹后调用 add_child() 的节点）。
