从iOS本地目录加载.rcproject [英] Loading .rcproject from iOS local directory

问题描述

我正在尝试从本地目录加载 rcproject .我的目标是从URL加载然后显示它.

I am trying to load a rcproject from a local directory. My target is, to load it from an URL and then show it.

如果我这样加载它:

let modelScene =  try? Entity.loadAnchor(named: "Experience")

一切正常.

但是，如果我这样做:

let url = URL(fileURLWithPath: "./Experience")

或

let url = URL(fileURLWithPath: "./Experience.rcproject")

和

let modelScene =  try? Entity.loadAnchor(contentsOf: url, withName: "Experience")

或

let modelScene =  try? Entity.loadAnchor(contentsOf: url)

我收到以下错误:

// [Pipeline] Failed to open scene 'Experience -- file:///'.

我不知道这里的问题是什么.有人知道我可以尝试什么吗?

I have no idea, what the issue here is. Did someone has an idea, what i can try?

我的发展目标是14.4

My development target is 14.4

在苹果 docs 中，他们写道，应该这样工作吧?

In the apple docs, they write, that it should work like this, right?

推荐答案

loadAnchor(contentsOf:withName:)类型方法由 .usd ，组成.usda ， .usdc ， .usdz 和 .reality 文件格式.但是官方文档说，现在它们仅适用于 Reality文件.您可以在此处阅读.

loadAnchor(contentsOf:withName:) type method was composed for .usd, .usda, .usdc, .usdz and .reality file formats. However official documentation says that now they work only for Reality files. You can read about it here.

public static func loadAnchor(contentsOf url: URL, 
                       withName resourceName: String?) throws -> AnchorEntity

这是代码中的定义:

支持的文件格式为USD或Reality.为了在整个网络会话中标识资源，该资源需要具有唯一的名称.此名称是使用 resourceName 设置的.网络会话中的所有参与者都需要加载资源并分配相同的 resourceName .

Supported file formats are USD or Reality. In order to identify a resource across a network session, the resource needs to have a unique name. This name is set using resourceName. All participants in the network session need to load the resource and assign the same resourceName.
