C#编写桌球运动

有两种方法（前题将重力取消）

1.将小球赋予弹力材质，追加力即可

2.如下将以下脚本挂到小球即可

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//尾翼效果为 trail renderer
public class Ball_test : MonoBehaviour {// Use this for initializationvoid Start () {//初始添加力transform.GetComponent<Rigidbody>().AddForce(transform.forward * Time.deltaTime * 0.001f);}//当碰到四周时private void OnCollisionEnter(Collision collision){//自身初始速度清零transform.GetComponent<Rigidbody>().velocity = new Vector3(0, 0, 0);//将自身正方向 、所碰到的物体的正方向 、所碰到的物体的角度传入Start_ball(transform.forward, collision.collider.transform.forward, collision.collider.transform.rotation.eulerAngles);}void Start_ball(Vector3 v1, Vector3 v2,Vector3 v3){//计算自身与四周碰撞夹角float angle = Vector3.Angle(v1, v2);//根据叉乘改变角度正负 满足左手定则Vector3 cross_angle = Vector3.Cross(v1, v2);//同方向if (cross_angle.y > 0){print("同");}//逆方向else{print("逆");angle = -angle;}print(angle);print(v2);Quaternion q = new Quaternion();//自身角度赋值q.eulerAngles = v3 + new Vector3(0, angle, 0);transform.rotation = q;//再次添加正方向的力transform.GetComponent<Rigidbody>().AddForce(transform.forward * Time.deltaTime * 0.001f);}
}
