Question

带有枚举的脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class InteractableItem : MonoBehaviour
{
    public enum InteractableMode // your custom enumeration
    {
        Description,
        Action
    };

    public InteractableMode interactableMode = InteractableMode.Description;

    public float distance;

    private bool action = true;

    [TextArea(1, 10)]
    public string description = "";

    public void ActionOnItem()
    {
        if(interactableMode == InteractableMode.Action && distance <= 5f && action == true)
        {


            action = false;
        }
    }
}

                    transitionToNextTarget = false;
                    finalLookWeight = 0f;

            }

            // Show primary object found by the player
            if (primaryTarget != null) text.text = "Item found: " + primaryTarget.description;
            else text.text = "Item found: none";

            // Show all objects found by the player
            if (allDetectedItems.Count > 0)
            {
                string result = "";
                foreach (InteractableItem item in allDetectedItems)
                {
                    result += item.description + "\n";
                }
                textMultiLine.text = result;
            }
            else
            {
                textMultiLine.text = "No items found.";
            }
        }
    }

    private void ThrowObject()
    {
        if(target.interactableMode.)
        objToThrow.transform.position = Vector3.MoveTowards(objToThrow.transform.position, target.transform.position, throwSpeed * Time.deltaTime);
    }

    private void Update()
    {
        if (throwObj == true)
        {
            ThrowObject();
        }
    }
}

在ThrowObject方法的底部，我仅当对象枚举模式设置为Action时才希望它抛出对象：

private void ThrowObject()
        {
            if(target.interactableMode.)
            objToThrow.transform.position = Vector3.MoveTowards(objToThrow.transform.position, target.transform.position, throwSpeed * Time.deltaTime);
        }

问题是我可以访问IF中的变量target.interactableMode，但不能访问自身的枚举。我想检查目标是否处于动作模式，然后抛出对象。

枚举在一个类中，因此要调用她，您必须先调用该类，然后再调用该枚举： YourClass.YourEnum

在您的情况下： InteractableItem.InteractableMode

要访问此枚举中的值： InteractableItem.InteractableMode.Action

如何从另一个脚本访问脚本中的枚举？
