libGDX:3d 动画不起作用 [英] libGDX: 3d animation not working

问题描述

我使用 Blender 和 fbxconv 创建了一个 .g3db 动画文件.现在，我的 libGDX 项目源代码如下所示:

I've created a .g3db animation file using Blender and fbxconv. Now, my libGDX project source code looks something like this:

public class test implements ApplicationListener {
// ...
 public ModelInstance fred
 public AnimationController animationController;

 public void create () {
    modelBatch = new ModelBatch();
    // ... 

    assets = new AssetManager();
    assets.load("data/fred.g3db", Model.class);
    loading = true;
 }

 private void doneLoading() {
    Model fredData = assets.get("data/fred.g3db", Model.class);

    fred = new ModelInstance(fredData);
    animationController = new AnimationController(fred);
    animationController.animate(fred.animations.get(0).id, -1, 1f, null, 0.2f);

    loading = false;
 }

 public void render () {
    if (loading && assets.update())
        doneLoading();
    camController.update();

    Gdx.gl.glViewport(0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);

    if(!loading) {
    animationController.update(10);
        modelBatch.begin(cam);
        modelBatch.render(fred,lights);
        modelBatch.end();
    }
 }

// [...] 
}

当我打开这个游戏时，模型完美显示，但根本没有动画.我对 libGDX 游戏编程比较陌生，所以我不知道我哪里出错了.有什么想法吗?

When I open this game, the model shows up perfectly, but there's no animation at all. I'm relatively new to libGDX game programming, so I have no ideas where I could have gone wrong. Any ideas?

(我不知道这是否与任何事情有关，但是当我使用 fbxconv 转换 fbx 文件时，我收到了几个警告，看起来像这样:

(I don't know if this has something to do with anything, but when I converted the fbx file using fbxconv, I got several warnings, all looking like this:

WARNING: Node XXX uses RrSs mode, transformation might be incorrect.

但是如果我读到的关于这个警告的信息是真的，它实际上应该不会引起任何问题......)

But if what I read about this warning is true, it shouldn't actually cause any problems...)

推荐答案

您是否启用了 OpenGL ES2.0?也看看:https://github.com/libgdx/libgdx/wiki/3D-animations-and-skinning.您应该向 animationController.update() 提供增量值.如果您使用 Blender 创建 FBX 文件，则可以放心地忽略 RrSs 警告.

Did you enable OpenGL ES2.0? Also have a look at: https://github.com/libgdx/libgdx/wiki/3D-animations-and-skinning. You should provide the delta value to animationController.update(). If you used blender to create the FBX file, you can safely ignore the RrSs warning.
