unity3d之相机跟随人物

一.第三人称视角 _1

先设置好相机与玩家之间的角度

给相机添加代码

 using UnityEngine;

 using System.Collections;

 namespace CompleteProject

 {

     public class CameraFollow : MonoBehaviour

     {

         public Transform target;            // The position that that camera will be following.

         public float smoothing = 5f;        // The speed with which the camera will be following.

         Vector3 offset;                     // The initial offset from the target.

         void Start ()

         {

             // Calculate the initial offset.

             offset = transform.position - target.position;

         }

         void FixedUpdate ()

         {

             // Create a postion the camera is aiming for based on the offset from the target.

             Vector3 targetCamPos = target.position + offset;

             // Smoothly interpolate between the camera's current position and it's target position.

            //相机平滑的移动到目标位置，插值

             transform.position = Vector3.Lerp (transform.position, targetCamPos, smoothing * Time.deltaTime);

         }

     }

 }

二、第三人称视角_2，可自己根据游戏效果调节位置

在inspector面板修改mHeight与mDistance值即可

 using System.Collections;

 using System.Collections.Generic;

 using UnityEngine;

 public class FollowCamera : MonoBehaviour

 {

     public Transform mTarget; //相机的跟随目标

     public float mHeight=8f;

     public float mDistance=6f;

     public float interpolation = 20.0f;

     public Space space = Space.World;

     // Use this for initialization

     void Start ()

     {

     }

     // Update is called once per frame

     void LateUpdate ()

     {

         if (mTarget)

         {

             Vector3 dest = Vector3.zero;

             switch (space)

             {

                 case Space.World://以世界为中心

                     dest = mTarget.position + Vector3.up * mHeight - Vector3.forward * mDistance;

                     break;

                 case Space.Self://玩家为中心，一般用不到可省略switch

                     dest = mTarget.position + mTarget.up * mHeight - mTarget.forward * mDistance;

                     break;

                 default:

                     break;

             }

             transform.position = Vector3.Lerp(transform.position, dest, interpolation);

             transform.LookAt(mTarget.position);

         }

     }

 }
