Ball

创建一个Sphere，改名为Ball1，为Ball1 添加 RigidBody, Network Transform, Network Identity

为 Ball1 添加脚本 Ball1.cs：

using UnityEngine;
using Mirror;

public class Ball1 : NetworkBehaviour
{
    public float speed = 10f;

    private Rigidbody rig;
    
    private Vector3 vel = new Vector3(0, 0, 0);

    public override void OnStartServer()
    {
        base.OnStartServer();
        rig = GetComponent<Rigidbody>();

    }

    [ServerCallback]
    private void OnCollisionEnter(Collision collision)
    {
        float y = collision.relativeVelocity.y > 0 ? 1 : -1;
        vel.y = y * speed;
        rig.velocity = vel;
    }
}

Player

修改Player Prefab:
在这里插入图片描述

Network Manager1

继承于 NetworkManager

using UnityEngine;
using Mirror;

[AddComponentMenu("")]
public class NetworkManager1 : NetworkManager
{
    GameObject player;

    private Vector3 lhs = new Vector3(-2, -2, 0);
    private Vector3 rhs = new Vector3(2, -4, 0);

    public override void OnServerAddPlayer(NetworkConnection conn)
    {
        if (numPlayers == 0)
        {
            player = Instantiate(playerPrefab, lhs, transform.rotation);
        }
        else if (numPlayers == 1)
        {
            player = Instantiate(playerPrefab, rhs, transform.rotation);
        }

        NetworkServer.AddPlayerForConnection(conn, player);
    }
}
