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

 1 using UnityEngine;
 2 using System.Collections;
 3 
 4 namespace CompleteProject
 5 {
 6     public class CameraFollow : MonoBehaviour
 7     {
 8         public Transform target;            // The position that that camera will be following.
 9         public float smoothing = 5f;        // The speed with which the camera will be following.
10 
11 
12         Vector3 offset;                     // The initial offset from the target.
13 
14 
15         void Start ()
16         {
17             // Calculate the initial offset.
18             offset = transform.position - target.position;
19         }
20 
21 
22         void FixedUpdate ()
23         {
24             // Create a postion the camera is aiming for based on the offset from the target.
25             Vector3 targetCamPos = target.position + offset;
26 
27             // Smoothly interpolate between the camera's current position and it's target position.
28            //相机平滑的移动到目标位置，插值
29             transform.position = Vector3.Lerp (transform.position, targetCamPos, smoothing * Time.deltaTime);
30         }
31     }
32 }

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

 1 using System.Collections;
 2 using System.Collections.Generic;
 3 using UnityEngine;
 4 
 5 public class FollowCamera : MonoBehaviour 
 6 {
 7     public Transform mTarget; //相机的跟随目标
 8     public float mHeight=8f;
 9     public float mDistance=6f;
10     public float interpolation = 20.0f;
11     public Space space = Space.World;
12 
13     // Use this for initialization
14     void Start () 
15     {
16         
17     }
18     
19     // Update is called once per frame
20     void LateUpdate () 
21     {
22         if (mTarget)
23         {
24             Vector3 dest = Vector3.zero;
25             switch (space)
26             {
27                 case Space.World://以世界为中心
28                     dest = mTarget.position + Vector3.up * mHeight - Vector3.forward * mDistance;
29                     break;
30                 case Space.Self://玩家为中心，一般用不到可省略switch
31                     dest = mTarget.position + mTarget.up * mHeight - mTarget.forward * mDistance;
32                     break;
33                 default:
34                     break;
35             }
36             transform.position = Vector3.Lerp(transform.position, dest, interpolation);
37             transform.LookAt(mTarget.position);
38         }
39     }
40 }
