一、纠正摄像头的一些僵硬

• 摄像头的问题
  ①有一点tad jittery ,因为是用了lerp，我们应该用smooth tamp
  ②当人物沿着墙边走，摄像头可以看出来已跑进墙体里面了
  
• 修正
  ①先修正jittery：方法就是修改camera Handler

using System.Collections;
using System.Collections.Generic;
using UnityEngine;namespace SG
{public class CameraHandler : MonoBehaviour{//摄像头即将要到达的坐标public Transform targetTransform;//摄像头真正的实时坐标public Transform cameraTransform;//this is how camera is going to turn on a swivel(转向),make camera rotate,rotate around the pivot//让摄像机绕pivot旋转的坐标public Transform cameraPivotTransform;//人物坐标private Transform myTransform;//摄像头的坐标private Vector3 cameraTransformPosition;//用于摄像头碰撞的bit位private LayerMask ignoreLayers;private Vector3 cameraFollowVelocity = Vector3.zero;public static CameraHandler singleton;//初始化默认值public float lookSpeed = 0.1f;public float followSpeed = 0.1f; public float pivotSpeed = 0.03f;private float targetPosition;//默认摄像头的z轴坐标private float defaultPosition; private float lookAngle;private float pivotAngle;public float minimimPivot = -35;public float maximumPivot = 35;public float cameraSphereRadius = 0.2f;public float cameraCollisionOffset = 0.2f;public float minimumCollisionOffset = 0.2f;public void Awake(){singleton = this;//Application.targetFrameRate = 60;//自己坐标就是人物的坐标myTransform = transform;defaultPosition = cameraTransform.localPosition.z;//下节课将更多摄像头和环境忽略的layer碰撞ignoreLayers = ~(1 << 8 | 1 << 9 | 1 << 10);}//will be used on update, 意味着每帧都会调用，让摄像头去跟随targettransform的top position(z轴顶部位置)，也就是让摄像头跟着人走 public void FollowTarget(float delta){//Vector3 targetPosition = Vector3.Lerp(myTransform.position, targetTransform.position, delta / followSpeed);Vector3 targetPosition = Vector3.SmoothDamp(myTransform.position, targetTransform.position, ref cameraFollowVelocity,delta / followSpeed);myTransform.position = targetPosition;//调整摄像头碰撞HandleCameraCollisions(delta);}//这个函数去掌握摄像头的旋转public void HandlerCameraRotation(float delta,float mouseXInput,float mouseYInput){//这样摄像头就会处在两个pivot之间，不能走更高或更低lookAngle += (mouseXInput * lookSpeed) / delta;pivotAngle -= (mouseYInput * pivotSpeed) / delta;//这会让摄像头卡在两个pivot角度之前，不能更高或更低（总体70°）pivotAngle = Mathf.Clamp(pivotAngle, minimimPivot, maximumPivot);Vector3 rotation = Vector3.zero;rotation.y = lookAngle;Quaternion targetRotation = Quaternion.Euler(rotation);myTransform.rotation = targetRotation;rotation = Vector3.zero;rotation.x = pivotAngle;targetRotation = Quaternion.Euler(rotation);cameraPivotTransform.localRotation = targetRotation;}private void HandleCameraCollisions(float delta){targetPosition = defaultPosition;RaycastHit hit;Vector3 direction = cameraTransform.position - cameraPivotTransform.position;direction.Normalize();if(Physics.SphereCast(cameraPivotTransform.position,cameraSphereRadius,direction,out hit,Mathf.Abs(targetPosition),ignoreLayers)){float dis = Vector3.Distance(cameraPivotTransform.position, hit.point);targetPosition = -(dis - cameraCollisionOffset);}if(Mathf.Abs(targetPosition) < minimumCollisionOffset){targetPosition = -minimumCollisionOffset;}cameraTransformPosition.z = Mathf.Lerp(cameraTransform.localPosition.z, targetPosition, delta / 0.2f);cameraTransform.localPosition = cameraTransformPosition;}}}

二、撰写摄像头碰撞检测函数

        private void HandleCameraCollisions(float delta){targetPosition = defaultPosition;RaycastHit hit;Vector3 direction = cameraTransform.position - cameraPivotTransform.position;direction.Normalize();if(Physics.SphereCast(cameraPivotTransform.position,cameraSphereRadius,direction,out hit,Mathf.Abs(targetPosition),ignoreLayers)){float dis = Vector3.Distance(cameraPivotTransform.position, hit.point);targetPosition = -(dis - cameraCollisionOffset);}if(Mathf.Abs(targetPosition) < minimumCollisionOffset){targetPosition = -minimumCollisionOffset;}cameraTransformPosition.z = Mathf.Lerp(cameraTransform.localPosition.z, targetPosition, delta / 0.2f);cameraTransform.localPosition = cameraTransformPosition;}

三、为摄像头新功能做调整

①调整camera Holder和Camera Pivot的Layer为Controller
②Main Camera保持为default的就行
