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);
         }
     }
 }
