Unity问题与解决方案：Photon实例化（PhotonNetwork.Instantiate参数详解）

Photon不知道为什么文档是真的少…只能自己读源码了，先来看一下这个方法声明吧：

/// <summary>
/// Instantiate a prefab over the network. This prefab needs to be located in the root of a "Resources" folder.
/// </summary>
/// <remarks>Instead of using prefabs in the Resources folder, you can manually Instantiate and assign PhotonViews. See doc.</remarks>
/// <param name="prefabName">Name of the prefab to instantiate.</param>
/// <param name="position">Position Vector3 to apply on instantiation.</param>
/// <param name="rotation">Rotation Quaternion to apply on instantiation.</param>
/// <param name="group">The group for this PhotonView.</param>
/// <param name="data">Optional instantiation data. This will be saved to it's PhotonView.instantiationData.</param>
/// <returns>The new instance of a GameObject with initialized PhotonView.</returns>
public static GameObject Instantiate(string prefabName, Vector3 position, Quaternion rotation, byte group, object[] data)

参数	说明
prefabName	prefab的名字，要求该预制物必须在一个Resources文件夹的根目录下，而且该预制物必须附有PhotonView脚本
position	实例化的位置
rotation	实例化的角度
group	群组，好像可以限制只对某一些客户端实例化，这个我还没有搞明白，，一般都填0
data	实例化时候传递的数据，该值保存在PhotonView.instantiationData变量中，要注意传递的每一个Object必须是可序列化的，否则会报错，该值可以不填，默认为null

于是一些初始化的变量就可以在data中传递过去

这里再附上官方Demo中推荐的每个GameObject的PhotonView的获取方式：

private PhotonView pvCache = null;
    public PhotonView photonView
    {
        get
        {
            if (pvCache == null)
            {
                pvCache = PhotonView.Get(this);
            }
            return pvCache;
        }
    }
