镜头平滑跟随代码

晃晃

老外发布的一个摄像机跟随代码，主要用于赛车游戏中，比官方默认的那个效果要更强大些，下面是详细功能简介：

Here's another smooth camera script. Designed to follow a car smoothly and give you the ability to zoom out when the car is moving. Hope someone makes use of it.

    target = self explanatory
    distance = Standard distance to follow object
    height = The height of the camera
    heightDamping = Smooth out the height position
    lookAtHeight = An offset of the target
    parentRigidbody = Used to determine how far the camera should zoom out when the car moves forward
    rotationSnapTime = The time it takes to snap back to original rotation
    distanceSnapTime = The time it takes to snap back to the original distance or the zoomed distance (depending on speed of parentRigidyBody)
    distanceMultiplier = Make this around 0.1f for a small zoom out or 0.5f for a large zoom (depending on the speed of your rigidbody)


Looks best when you place the target transform on the front axle


代码如下：
using UnityEngine;
using System.Collections;
public class CarSmoothFollow : MonoBehaviour {
    public Transform target;
    public float distance = 20.0f;
    public float height = 5.0f;
    public float heightDamping = 2.0f;
    public float lookAtHeight = 0.0f;
    public Rigidbody parentRigidbody;
    public float rotationSnapTime = 0.3F;
    public float distanceSnapTime;
    public float distanceMultiplier;
    private Vector3 lookAtVector;
    private float usedDistance;
    float wantedRotationAngle;
    float wantedHeight;
    float currentRotationAngle;
    float currentHeight;
    Quaternion currentRotation;
    Vector3 wantedPosition;
    private float yVelocity = 0.0F;
    private float zVelocity = 0.0F;
    void Start () {
        lookAtVector =  new Vector3(0,lookAtHeight,0);
    }
    void LateUpdate () {
        wantedHeight = target.position.y + height;
        currentHeight = transform.position.y;
        wantedRotationAngle = target.eulerAngles.y;
        currentRotationAngle = transform.eulerAngles.y;
        currentRotationAngle = Mathf.SmoothDampAngle(currentRotationAngle, wantedRotationAngle, ref yVelocity, rotationSnapTime);
        currentHeight = Mathf.Lerp(currentHeight, wantedHeight, heightDamping * Time.deltaTime);
        wantedPosition = target.position;
        wantedPosition.y = currentHeight;
        usedDistance = Mathf.SmoothDampAngle(usedDistance, distance + (parentRigidbody.velocity.magnitude * distanceMultiplier), ref zVelocity, distanceSnapTime);
        wantedPosition += Quaternion.Euler(0, currentRotationAngle, 0) * new Vector3(0, 0, -usedDistance);
        transform.position = wantedPosition;
        transform.LookAt(target.position + lookAtVector);
    }
}
