Three.js + Cordova - 如何在不使用 server/http 的情况下加载纹理？
Three.js + Cordova - How to load textures without the use of a server/http?
我正在尝试使用 Three.js 制作一个可以玩的 Cordova 游戏离线，但似乎 Three.js 非常热衷于制作必须通过 http 提供纹理文件。有没有解决的办法？如果可能的话，我极力避免在我的游戏中使用 Node.js 服务器
在您提到无法完成之前，Google Play/App 商店中有很多 3D 游戏并且可以离线工作，例如 Temple 运行、Match 3D、等。这些是如何工作的？
由于尝试加载 GLB/GLTF 模型，必须在我的 index.js 文件中使用 import {GLTF} 方法，而我的 index.html 文件需要 index.js声明为 module，它又被 CORS
击中
我尝试将我的 .glb 文件转换为 .json 并使用 Three.js 的内置 ObjectLoader，但我收到错误 THREE.ObjectLoader: Can't load resources/models/test.json

它只是通过 XMLHttpRequest 执行 XHR 请求，因此加载本地文件应该没有任何问题，这完全取决于您的设置方式。
如果您使用的是 cordova-android 10，您可以尝试在 config.xml
中进行设置
<preference name="AndroidInsecureFileModeEnabled" value="true" />
对于 iOS，请尝试使用 cordova-plugin-ios-xhr 并将您的首选项设置为
<preference name="allowFileAccessFromFileURLs" value="true" />
<preference name="allowUniversalAccessFromFileURLs" value="true" />
我正在尝试使用 Three.js 制作一个可以玩的 Cordova 游戏离线，但似乎 Three.js 非常热衷于制作必须通过 http 提供纹理文件。有没有解决的办法？如果可能的话，我极力避免在我的游戏中使用 Node.js 服务器
在您提到无法完成之前，Google Play/App 商店中有很多 3D 游戏并且可以离线工作，例如 Temple 运行、Match 3D、等。这些是如何工作的？
由于尝试加载 GLB/GLTF 模型，必须在我的 index.js 文件中使用 import {GLTF} 方法，而我的 index.html 文件需要 index.js声明为 module，它又被 CORS
我尝试将我的 .glb 文件转换为 .json 并使用 Three.js 的内置 ObjectLoader，但我收到错误 THREE.ObjectLoader: Can't load resources/models/test.json

它只是通过 XMLHttpRequest 执行 XHR 请求，因此加载本地文件应该没有任何问题，这完全取决于您的设置方式。 如果您使用的是 cordova-android 10，您可以尝试在 config.xml

对于 iOS，请尝试使用 cordova-plugin-ios-xhr 并将您的首选项设置为
<preference name="allowFileAccessFromFileURLs" value="true" />
<preference name="allowUniversalAccessFromFileURLs" value="true" />
