我有一个多人项目设置，目的是创建一款生存游戏。在这个生存游戏中，我有玩家库存、外部库存（例如箱子），并且玩家能够丢弃物品，并将物品从库存中取消实例化，将数据传输到服务器，然后使用其实例在服务器上实例化该对象。已保存特定属性。
我遇到的问题是服务器主机，掉落物品机制按预期工作。然而，当客户端加入服务器时（它们可以移动、与对象交互、拾取在运行时实例化的任何对象，并使用传输到服务器的数据“射击”其他玩家，然后“击中”客户端），并且客户端尝试放下一个项目，它会发出信号，但服务器不会接受它收到的数据，并且不会为任何人实例化该节点。
向服务器发出信号并发送数据的播放器代码：
> func _on_inventory_drop_slot_data(grabbed_slot_data) -> void:
>
> print_debug("Sending object to server.")
> drop_item.emit(grabbed_slot_data)
接收数据并将数据实例化为服务器上的节点的服务器代码：
> func _on_inventory_drop_slot_data(grabbed_slot_data) -> void:
> print_debug("Server is receiving object.")
> if grabbed_slot_data:
> print_debug(grabbed_slot_data)
> else:
> print_debug("no slot data")
> var pick_up = PickUp.instantiate()
> pick_up.slot_data = grabbed_slot_data
> pick_up.position = Vector3(0,10,0)
> add_child(pick_up)
根据我的理解，一旦一个项目在服务器端为每个人实例化，每个人都应该能够看到该对象，对吗？如果情况并非如此，我是否需要使用 MultiplayerSpawner 节点来实例化所有客户端上掉落的物品，就像处理玩家实例一样？
如果您想查看的话，这是完整的播放器代码。

我尝试从连接到服务器的客户端发出信号，并且在测试“is_connected”时确认信号正在连接，但客户端没有从发射中获取数据并执行函数。
这就是问题所在，我需要连接信号两次。这是我必须第二次连接的地方：
func _on_multiplayer_spawner_spawned（节点）：
if node.is_multiplayer_authority():
node.health_changed.connect(update_health_bar)
node.drop_item.connect(_on_inventory_drop_slot_data)
