解析文件时出错：file.g3db，同时在libgdx中使用blender对象

标签： 3d libgdx blender fbx

我正在玩libGDX导入3d模型。我成功地将fbx文件转换为d3db。这是完整的错误，以下是show方法中使用的源代码。我从教程中获得了代码，它应该可以正常工作。转换器有问题吗？

答案 0 :(得分：0)

看起来非常简单的错误消息：“FileNotFoundException：convertedModel.g3db”。确保文件名（区分大小写）正确且文件存在。要进行验证，您可以将以下代码添加到show()方法的顶部。

Gdx.app.log("", Gdx.files.internal("convertedModel.g3db").exists() ? "exists" : "does not exist");

确保两行中的文件名一致（此行和对loadModel的调用）。

默认情况下，内部文件应位于Android项目的assets子文件夹中，或者，如果您没有Android项目，则应位于核心项目中。这是使用设置实用程序创建新项目时badlogic.jpg所在的位置。
