解决Host与Server的矛盾

在WeaponManager里

public class WeaponManager : NetworkBehaviour
{
    ...
    [ServerRpc]
    private void ToggleWeaponServerRpc()
    {
        //用IsHost优化逻辑
        if (!IsHost)
        {
            ToggleWeapon();
        }
        ToggleWeaponClientRpc();
    }

}

在Player中

public class Player : NetworkBehaviour
{  
    ...
    public void TakeDamage(int damage) {
        ...
        if (currentHealth.Value <= 0) {
            currentHealth.Value = 0;
            //优化
            if (!IsHost)
            {
                DieOnServer();
            }
            DieClientRpc();
        }
    }
    ...

}

给武器添加特效

先将需要的特效拖进文件夹Prefabs里

在M16里添加新物体FirePoint，把MuzzleFlash拖进去

调整枪火的位置，角度，大小

叉掉两个选项

沙鹰同理
创建一个WeaponGraphics脚本来管理特效

public class WeaponGraphics : MonoBehaviour
{
    public ParticleSystem muzzleFlash;

    //可能需要现时生成出来，所以用的GameObject
    public GameObject goopHitEffectPrefab;
    public GameObject stoneEffectPrefab;
}

把这个类分别给各种枪装上，并将对应的特效被WeaponGraphics引用

渲染特效

在WeaponManager里

public class WeaponManager : NetworkBehaviour
{
    ...
    //当前武器的特效
    private WeaponGraphics currentGraphics;
    ...

    //切换武器
    public void EquipWeapon(PlayerWeapon weapon) {
        ...
        //切换武器时要把当前的特效也换成武器相应的特效
        currentGraphics = weaponObject.GetComponent<WeaponGraphics>();
    }

    //动态返回当前特效
    public WeaponGraphics GetCurrentGraphics()
    {
        return currentGraphics;
    }
    ...
}

为了让火花渲染出来需要将PlayerShooting解禁，如果PlayerShooting被禁，ClientRpc内的函数就不能让客户端调用PlayerShooting类里面的OnShoot();

在PlayerShooting里

public class PlayerShooting : NetworkBehaviour
{
    ...

    //编写每次射击前的逻辑
    private void OnShoot()
    {
        //播放特效
        weaponManager.GetCurrentGraphics().muzzleFlash.Play();
    }

    [ClientRpc]
    private void OnShootClientRpc()
    {
        OnShoot();
    }

    [ServerRpc]
    private void OnShootServerRpc()
    {
        if (!IsHost)
        {
            OnShoot();
        }
        OnShootClientRpc();
    }


    private void Shoot() {

        OnShootServerRpc();
        ...
    }
    void Update()
    {
        if (!IsLocalPlayer) return;
        ...
    }

}

修复切枪连射bug

在PlayerShooting里

public class PlayerShooting : NetworkBehaviour
{
    ...
    void Update()
    {
        ...
        else //连发
        {
            ...

            //修复bug
            else if (Input.GetButtonUp("Fire1") || Input.GetKeyDown(KeyCode.Q))
            {
                //对Shoot()关闭周期函数
                CancelInvoke("Shoot");
            }
        }


    }

    ...
}

添加受击特效

修改特效参数，改成一个点

修改渲染时间

在PlayerShooting里

public class PlayerShooting : NetworkBehaviour
{
    //enum好像定义一组用于枚举的常量
    enum HitEffectMaterial
    {
        Goop,
        Stone
    }

    //传三个参数，位置，角度， 材质
    private void OnHit(Vector3 pos, Vector3 normal, HitEffectMaterial material)
    {
        GameObject hitEffectPrefab;
        if(material == HitEffectMaterial.Goop)
        {
            hitEffectPrefab = weaponManager.GetCurrentGraphics().goopHitEffectPrefab;
        }
        else
        {
            hitEffectPrefab = weaponManager.GetCurrentGraphics().stoneEffectPrefab;
        }
        //Quaternion.LookRotation(normal)可以返回normal的反方向
        GameObject hitEffectObject = Instantiate(hitEffectPrefab, pos, Quaternion.LookRotation(normal));
        //将特效物体转成粒子
        ParticleSystem particleSystem = hitEffectObject.GetComponent<ParticleSystem>();
        //瞬发
        particleSystem.Emit(1);
        particleSystem.Play();
        Destroy(hitEffectObject, 1f);

    }
    [ServerRpc]
    private void OnHitServerRpc(Vector3 pos, Vector3 normal, HitEffectMaterial material)
    {
        if (!IsHost)
        {
            OnHit(pos, normal, material);
        }
        OnHitClientRpc(pos, normal, material);
    }

    [ClientRpc]
    private void OnHitClientRpc(Vector3 pos, Vector3 normal, HitEffectMaterial material)
    {
        OnHit(pos, normal, material);
    }


    private void Shoot() {

        OnShootServerRpc();

        if (!IsLocalPlayer) return;

        //此为Raycast射中的物体，因为Physics.Raycast的返回值为bool类型
        RaycastHit hit;
        //Physics.Raycast对带有collider的物体进行信息反馈
        //射出位置， 射出方向， 射中物体，射程，需要穿过的物体

        //射击时改成当前武器
        if (Physics.Raycast(cam.transform.position, cam.transform.forward, out hit, currentWeapon.range, mask)) {
            //GameObject.ocllider.tag就能访问物体的标签
            if (hit.collider.tag == "Player") {
                //射线碰撞在客户端,而让受伤的逻辑在服务器上实现
                ShootServerRpc(hit.collider.name, currentWeapon.damage);
                OnHitServerRpc(hit.point, hit.normal, HitEffectMaterial.Goop);
            }
            else
            {
                OnHitServerRpc(hit.point, hit.normal, HitEffectMaterial.Stone);
            }
        }
    }
