修改副武连射bug

在PlayerShooting里

public class PlayerShooting : NetworkBehaviour
{
    void Update()
    {
        if (!IsLocalPlayer) return;

        //按k杀死自己
        if (Input.GetKeyDown(KeyCode.K))
        {
            ShootServerRpc(transform.name, 10000);
        }
        ...
    }

    //停止射击
    public void StopShooting()
    {
        CancelInvoke("Shoot");
    }

}

在Player里

public class Player : NetworkBehaviour
{  
    ...
    //具体的死亡逻辑,缴械
    private void Die()
    {
        GetComponent<PlayerShooting>().StopShooting();
        ...
    }


}

装弹

在PlayerWeapon里

public class PlayerWeapon
{
    ...
    public int maxBullets = 30;//最大弹夹
    public int bullets = 30;//现在的子弹数
    public float reloadTime = 2f;

    //隐藏起这一条变量
    [HideInInspector]
    public bool isReloading = false;
}

在WeaponManager里

public class WeaponManager : NetworkBehaviour
{
    ...
    //重新装弹
    public void Reload(PlayerWeapon playerWeapon)
    {
        //如果在装弹就不能装弹了
        if (playerWeapon.isReloading) return;
        playerWeapon.isReloading = true;

        print("Reloading ...");
        StartCoroutine(ReloadCoroutine(playerWeapon));
    }

    //延时函数, 协同函数
    private IEnumerator ReloadCoroutine(PlayerWeapon playerWeapon)
    {
        yield return new WaitForSeconds(playerWeapon.reloadTime);

        playerWeapon.bullets = playerWeapon.maxBullets;
        playerWeapon.isReloading = false; 
    }
}

在PlayerShooting里

public class PlayerShooting : NetworkBehaviour
{
    void Update()
    {
        ...
        //按k杀死自己
        if (Input.GetKeyDown(KeyCode.K))
        {
            ShootServerRpc(transform.name, 10000);
        }
        // 手动换弹
        if (Input.GetKeyDown(KeyCode.R))
        {
            weaponManager.Reload(currentWeapon);
            //装弹中不能开枪要return？
            return;
        }
        ...
    }
    private void Shoot() {
        if (currentWeapon.bullets <= 0 || currentWeapon.isReloading) return;
        currentWeapon.bullets--;
        print("Current bullets:" + currentWeapon.bullets);
        if (currentWeapon.bullets <= 0) weaponManager.Reload(currentWeapon); 

        ...
    }
    ...

}

UI设计

在PlayerSetup里

public class PlayerSetup : NetworkBehaviour
{
    public override void OnNetworkSpawn()
    {
        ...
        else
        {
            //当本地玩家进入网络时，开始绘制UI
            PlayerUI.Singleton.setPlayer(GetComponent<Player>());
            ...
        }
    ...
}

在PlayerUI里

public class PlayerUI : MonoBehaviour
{
    //让PlayerUI做一个单例模式
    public static PlayerUI Singleton;
    //UI是本地玩家的UI
    private Player player = null;
    [SerializeField]
    private TextMeshProUGUI bulletsText;
    [SerializeField]
    private GameObject bulletsUI;
    private WeaponManager weaponManager;


    private void Awake()
    {
        Singleton = this;
    }

    public void setPlayer(Player localPlayer)
    {
        player = localPlayer;
        //将UI亮出来
        bulletsUI.SetActive(true);
        weaponManager = player.GetComponent<WeaponManager>();
    }

    void Update()
    {
        if (player == null) return;
        var currentWeapon = weaponManager.GetCurrentWeapon();
        if (currentWeapon.isReloading)
        {
            bulletsText.text = "Reloading ...";
        }
        else
        {
            bulletsText.text = currentWeapon.bullets + " / " + currentWeapon.maxBullets;
        }
    }
}

生命条

在PlayerUI里

public class PlayerUI : MonoBehaviour
{
    ...
    //因为要缩进血条，所有用Transform
    [SerializeField]
    private Transform healthBarFill;
    //而要显出或消失血条UI，所以是GameObject
    [SerializeField]
    private GameObject healthBarUI;

    public void setPlayer(Player localPlayer)
    {
        ...
        //将UI亮出来
        healthBarUI.SetActive(true);
    }

    void Update()
    {
        ...
        healthBarFill.localScale = new Vector3(player.GetHealth() / 100f, 1f, 1f); 
    }
}

敌方玩家的血条

给UI加上逻辑

在PlayerInfo里

public class PlayerInfo : MonoBehaviour
{
    [SerializeField]
    private TextMeshProUGUI playername;
    [SerializeField]
    private Transform playerHealth;
    [SerializeField]
    private GameObject playerHealthUI;
    [SerializeField]
    private Transform infoUI;

    private Player player;

    private void Start()
    {
        player = GetComponent<Player>();
    }

    void Update()
    {
        playername.text = transform.name;
        playerHealth.localScale = new Vector3(player.GetHealth() / 100f, 1f, 1f);

        //Info永远朝向camera
        //将玩家的Camera设为主Camera，刚好是可以和界面的camera错开
        var camera = Camera.main;
        infoUI.transform.LookAt(infoUI.transform.position + camera.transform.rotation * Vector3.back, camera.transform.rotation * Vector3.up);
        infoUI.Rotate(new Vector3(0f, 180f, 0f));

    }
}
