c# - 在命名空间中访问类中的 float

Question

我正在尝试从另一个脚本更改下面脚本中“XSensitivity”的值。

using System;
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;

namespace UnityStandardAssets.Characters.FirstPerson
{
[Serializable]
public class HeadLook
{
    public float XSensitivity = 8f;
    public float YSensitivity = 8f;
    public float MinimumX = -60F;
    public float MaximumX = 60F;

    public float xRotRaw;
    public float yRotRaw;

    public HeadLook (float rotX, float rotY)
    {
        rotX = XSensitivity;
        rotY = YSensitivity;
    }
    // create an instance (an Object) of the HeadLook class
    public HeadLook MyHeadLook = new HeadLook(8,8);

    private float xRot;
    private float yRot;

    private float xRotation;
    private float yRotation;

    //          ----------------------------
    public void LookRotation(Transform character, Transform head)
    {
        yRotRaw = CrossPlatformInputManager.GetAxisRaw("HorizontalLook");
        xRotRaw = CrossPlatformInputManager.GetAxisRaw("VerticalLook");

        yRot = CrossPlatformInputManager.GetAxisRaw("HorizontalLook") * XSensitivity;
        xRot = CrossPlatformInputManager.GetAxisRaw("VerticalLook") * YSensitivity;

        yRotation -= yRot * 10 * Time.deltaTime;
        yRotation = yRotation % 360;
        xRotation += xRot * 10 * Time.deltaTime;
        xRotation = Mathf.Clamp(xRotation, MinimumX, MaximumX);
        head.localEulerAngles = new Vector3(-xRotation, -0, 0);
        character.localEulerAngles = new Vector3(0, -yRotation, 0);
    }
    //          ----------------------------
}
}

我认为这可能有效，但出现错误。

    using UnityEngine;
using UnityStandardAssets.Characters.FirstPerson;

private HeadLook m_HeadLook;

void Awake ()
{
    m_HeadLook = GetComponent< HeadLook >();
    sensitivitySlider.value =  m_HeadLook.MyHeadLook.XSensitivity;
}

我得到的错误是..
ArgumentException: GetComponent 要求请求的组件“HeadLook”派生自 MonoBehaviour 或 Component 或者是一个接口(interface)。

谢谢。

你只需要从 monobehaviour 派生你的类:

using System;
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;

namespace UnityStandardAssets.Characters.FirstPerson
{
[Serializable]
public class HeadLook : MonoBehaviour
{
...
