如何使用脚本来提供另一个脚本设置？

Question

第一个脚本附加到一个空的GameObject。

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

[System.Serializable]
public class SpinableObject
{
    public Transform t;
    public float rotationSpeed;
    public float minSpeed;
    public float maxSpeed;
    public float speedRate;
    public bool slowDown;
}
public class SpinObject : MonoBehaviour
{
    public SpinableObject[] objectsToRotate;
    private Rotate _rotate;
    private int index = 0;

    // Use this for initialization
    void Start()
    {
        _rotate = new Rotate>();
    }

    // Update is called once per frame
    void Update()
    {
        var _objecttorotate = objectsToRotate[index];
        _rotate.rotationSpeed = _objecttorotate.rotationSpeed;
        _rotate.minSpeed = _objecttorotate.minSpeed;
        _rotate.maxSpeed = _objecttorotate.maxSpeed;
        _rotate.speedRate = _objecttorotate.speedRate;
        _rotate.slowDown = _objecttorotate.slowDown;
    }
}

第二个脚本被附加到GameObject/s上，我想提供信息。因此，这个脚本被单独地附加到每个GameObject上。

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

public class Rotate : MonoBehaviour
{
    public float rotationSpeed;
    public float minSpeed;
    public float maxSpeed;
    public float speedRate;
    public bool slowDown;

    // Use this for initialization
    void Start ()
    {

    }

    // Update is called once per frame
    void Update ()
    {
        RotateObject();
    }

    public void RotateObject()
    {
        if (rotationSpeed > maxSpeed)
            slowDown = true;
        else if (rotationSpeed < minSpeed)
            slowDown = false;

        rotationSpeed = (slowDown) ? rotationSpeed - 0.1f : rotationSpeed + 0.1f;
        transform.Rotate(Vector3.forward, Time.deltaTime * rotationSpeed);
    }
}

不知道这是不是我想做的好办法？

第二个问题是，第一个脚本中的变量_rotate一直为null：

我在做：

_rotate = new Rotate>();

但这里仍然是空的：

_rotate.rotationSpeed = _objecttorotate.rotationSpeed;

Answer 1

我想你不明白团结是怎么运作的。

首先，_rotate = new Rotate>();不是有效的C#，将引发错误。

其次，在您的示例中，Rotate是一个没有附加到GameObject的MonoBehaviour。我认为无论你想要实现什么，也许都是一步之遥。您可以将一个独立的Update-call (我甚至不知道它是否得到了它的Update-method调用)与另一个对象同步。简而言之:在我看来，你的代码似乎是胡说八道。

我建议您将RotateObject方法移动到SpinableObject中，并从SpinObject调用它，而不是将内容推入_rotate。这应该能行。

using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class SpinableObject
{
    public Transform t;
    public float rotationSpeed;
    public float minSpeed;
    public float maxSpeed;
    public float speedRate;
    public bool slowDown;

    public void RotateObject()
    {
        if (rotationSpeed > maxSpeed)
            slowDown = true;
        else if (rotationSpeed < minSpeed)
            slowDown = false;

        rotationSpeed = (slowDown) ? rotationSpeed - 0.1f : rotationSpeed + 0.1f;
        t.Rotate(Vector3.forward, Time.deltaTime * rotationSpeed);
    }
}
public class SpinObject : MonoBehaviour
{
    [SerializeField]
    private SpinableObject[] objectsToRotate;

    // Update is called once per frame
    void Update()
    {
        foreach(var spinner in objectsToRotate)
            spinner.RotateObject();
    }
}
