Question

我试图在libgdx中渲染一个模型 - 一切都在桌面上完美运行，但在android上停止modelBatch.render(poleInstance, environment);

是的，我的问题类似于this，但更新图书馆并没有帮助是的，文件com/badlogic/gdx/graphics/g3d/shaders/default.vertex.glsl到位

我的代码放置here

Answer 1

错误是File not found，显然无法找到该文件。如果您确定包含该文件，则可能是由重复引用引起的（尽管它不必）。例如，如果在核心和android项目中包含（并导出）gdx库。您可以通过右键单击每个项目来检查这一点，单击Java Build Path，然后单击Order and Export选项卡。确保在核心项目中仅包含gdx项目（或jar，取决于您是从源或夜间/稳定工作）（并通过单击复选框导出）。

但是，在类路径上拥有资源（着色器文件）只是为了支持libgdx的开箱即用渲染。在您的情况下，建议将着色器文件复制到您的资源文件夹的（子文件夹）并使用它们。这使得管理资产变得更加清晰。您可以使用ModelBatch的构造函数加载着色器，例如：

modelbatch = new ModelBatch(Gdx.files.internal("data/default.vertex.glsl"), Gdx.files.internal("data/default.fragment.glsl"));

当然，您仍然可能需要仔细检查项目配置。

请在Arm Transition

上安装Genymotion Emulator

以下是有关如何安装此转换的详细指南：
