void Update (){target = GameObject.Find("new_offer");// 滾輪設(shè)置相機與人物的距離.if(Input.GetAxis("Mouse ScrollWheel") != 0){theDistance = theDistance + Input.GetAxis("Mouse ScrollWheel") * Time.deltaTime * ScrollKeySpeed;}// 鼠標(biāo)中間滾動得到的值是不確定的,不會正好就是0,或 -10,當(dāng)大于0時就設(shè)距離為0,小于MaxDistance就設(shè)置為MaxDistanceif(theDistance>0){ theDistance = 0;}if(theDistance < MaxDistance){ theDistance = MaxDistance;}transform.position = target.transform.position;SetDistance();}void Start (){if (rigidbody){rigidbody.freezeRotation = true;transform.position = target.transform.position;}}//設(shè)置相機與人物之間的距離void SetDistance(){transform.Translate(Vector3.forward * theDistance);}請問，運行時發(fā)現(xiàn)攝像頭只是上下移動，并不實現(xiàn)拉近后退的效果，這是為什么？

不是distance，是fieldOfView，把下面的代碼保存為C#再賦給主相機

using UnityEngine;
using System.Collections;

public class CubeStatic : MonoBehaviour
{

public float minFov = 15f;
public float maxFov = 90f;
public float sensitivity = 10f;

void Update()
{
float fov = Camera.main.fieldOfView;
fov += Input.GetAxis("Mouse ScrollWheel") * sensitivity;
fov = Mathf.Clamp(fov, minFov, maxFov);
Camera.main.fieldOfView = fov;
}
}
