三、摄像机跟随汽车移动，第一视角

线性插值

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class FollowPlayer : MonoBehaviour {
    private Transform followTarget; // 跟随的目标对象
    private Vector3 fixedDistance; // 相机与目标的固定距离
    private Vector3 tempPos; // 相机的临时位置

    void Start () {
        followTarget = GameObject.FindGameObjectWithTag("Player").transform; // 通过标签获取跟随的目标对象
        fixedDistance = new Vector3(0, 3, -6); // 设置相机与目标的固定距离
    }

    void FixedUpdate () {
        tempPos = followTarget.TransformDirection(fixedDistance) + followTarget.position; // 计算相机的临时位置
        transform.position = Vector3.Lerp(transform.position, tempPos, Time.fixedDeltaTime * 3); // 平滑地将相机移动到临时位置
        transform.LookAt(followTarget); // 让相机朝向目标对象
        //Quaternion q = Quaternion.LookRotation(Vector3.forward,followTarget.position);
        //transform.rotation = Quaternion.Slerp(transform.rotation, q, Time.fixedDeltaTime * 3);
        // 上面两行代码是注释掉的，不会被执行
    }

四、 车轮碰撞器、控制移动

给四个轮胎都添加车轮碰撞器

using System.Collections.Generic;
using UnityEngine;

public class car : MonoBehaviour {
    
	private MeshRenderer[] wheelMesh;
	private WheelCollider[] wheel;
	private float maxAngle;
	private float maxTorque;
    
	void Start () {
		maxAngle = 30;
		maxTorque = 200;
		wheelMesh = transform.GetChild(0).GetComponentsInChildren<MeshRenderer>();
		wheel = transform.GetChild(1).GetComponentsInChildren<WheelCollider>();
	}
    
	void Update () {
		float h = Input.GetAxis("Horizontal");
		float v = Input.GetAxis("Vertical");
	
		
		for (int i = 0; i < 2; i++)
		{
			wheel[i].steerAngle = h * maxAngle;
		
		}
		
		foreach (var o in wheel)
		{
			o.motorTorque = maxTorque * v;
		}

		for (int i = 0; i < 4; i++)
		{
			wheelMesh[i].transform.localRotation = Quaternion.Euler(wheel[i].rpm * 360 / 60, wheel[i].steerAngle, 0);
		}

		
		
		
	}
	
	
	
	
}
