当玩家开枪时，它正在失去生命

Question

我正在制作一个多人游戏2d，当我的玩家开枪时(枪也有对撞机(，这会影响他的生活，我不知道为什么。可能是因为当目标"；伤害；有RPCtarget.all，但我不知道该更改什么来影响游戏中的其他玩家，而不是我的。用什么我可以取代所有？

Answer 1

我认为在这种情况下您并不真正需要RPC。

我看到你的角色IPunObservable，我想，添加到了PhotonView中。因此，它的健康状况将自动同步。您还可以使用PhotonNetwork实例化项目符号，这意味着它们也将同步并具有PhotonView。

所以每个玩家都有所有的同步子弹和其他玩家。

这意味着，你只需要检查子弹是否来自其他玩家，并在本地设置伤害(别担心，结果会同步(，如下所示：

. . .
private void OnTriggerEnter2D(Collider2D col)
{
if (col.gameObject.CompareTag("Hurt"))
{
// if hurt object is not mine, take damage
if (!col.gameObject.GetPhotonView().isMine) 
Damage();
}
if (col.gameObject.tag == "PowerUp")
{
if (photonView.IsMine)
{
var powerup = col.GetComponent<PowerUp>();
powerup.Pickup(this);
}
else
{
}
}
if (col.gameObject.CompareTag("Bullet"))
{
// if bullet is not mine, take damage
if (!col.gameObject.GetPhotonView().isMine)
Damage();
}
else
{
}
}
// no rpc
void Damage()
{
if (!photonView.IsMine) // only player can change his life
return;
if (Health > 0)
{
Health -= 20;
}
if (Health <= 0) // check health status
{
myCounts.RpcRespawn(); //Here you should to call counter
photonView.transform.position = Vector2.zero;
Health = 100;
}
}
