Unity GetComponent<>().GetObject 返回 false 与 Equals

Question

我有课

ProtagonistActor

。我里面有一个公共吸气剂

GetActorState

.

在不同的班级

InputManager

我有：

ProtagonistActor _protagonistActor;
ActorState _actorState;

private void Awake()
{
    _protagonistActor = GetComponent<ProtagonistActor>();
    _actorState = _protagonistActor._actorState;
}

void OnJumpEvent()
{
    Debug.Log($"Comparingggggggggg {_protagonistActor._actorState.Equals(_actorState)} {_protagonistActor._actorState == _actorState}");
}

我期待日志打印 True 但它正在打印 False 两者。

这怎么可能？

GetComponent<ProtagonistActor>().GetSome...

getter 返回一个新的引用吗？

我事件打印出哈希码，它们显示不同的值，如何？

Comparingggggggggg False False 1301530776 -256054432

详细代码示例：

[Serializable]
public class ActorState
{
    public int tempP;
}

public class ProtagonistActor: MonoBehaviour // Attached to gameobject
{
    [SerializeField] 
    public ActorState _actorState;

    private void Awake()
    {
        InitiateActorState();
    }

    void InitiateActorState()
    {
        _actorState = new ActorState();
    }
}

public class Test2: MonoBehaviour //Attached to Gameobject Player
{
    private ProtagonistActor _protagonistActor;
    private ActorState _actorState;

    private void Awake()
    {
        _protagonistActor = GetComponent<ProtagonistActor>();
        _protagonistActor._actorState.tempP = 90;
        _actorState = _protagonistActor._actorState;
    }

    void OnMyJump()
    {
        Debug.Log($"Comparingggggggggg {_protagonistActor._actorState.tempP} {_actorState.tempP} {_protagonistActor._actorState.Equals(_actorState)} {_protagonistActor._actorState == _actorState} {_protagonistActor._actorState.GetHashCode()} {_actorState.GetHashCode()}");
    }
}

输出

Comparingggggggggg 0 90 False False 744599944 781808744

检查方法的调用顺序。您可以在每个方法中使用简单的

Debug.Log

来实现。

看来你测试的

Awake

方法比你的

Awake

类的

ProtagonistActor

更早调用。在这种情况下，你会有这样的逻辑：

• Awake

  在测试中，缓存值为

  _actorState

  ，改变里面的参数

  _actorState

• Awake

  在

  ProtagonistActor

  类中，调用

  InitiateActorState

  方法并创建ActorState类的

  全新实例

  ，默认值为0.
