导入blender3D模型可以看上篇libgdx导入blender模型

本篇3D动画在上篇的基础上。

具体参考官网 3D 动画和蒙皮
blender动画参考 八个案例教程带你从0到1入门blender【已完结】

打开上次的blender的，选则物体属性

点击位置和旋转x，y，z后面的小点，确定初始x，y，z位置，和初始角度



更改数值，并点击锁后面的方块

点击播放，查看动画

导出fbx，与上篇导出模型一致。导出时需要选择自定义属性

转换为g3dj，这里看不明白的去看我上篇，不会blender的建模的去看视频教程

项目中使用，将导出的cube.g3dj放入项目assets/data下

}

这里主要与上篇导入模型的代码区别在于，增加了

ModelInstance instance;
AnimationController controller;
public void create() {...instance = new ModelInstance(model);controller = new AnimationController(instance);controller.setAnimation("Cube|CubeAction",-1);
}
public void render() {...controller.update(Gdx.graphics.getDeltaTime());...
}

代码中controller.setAnimation(“Cube|CubeAction”,-1); 动画的名字
用文本方式打开导出的cube.g3dj 可以看到"animations"数据块，看到id，就是动画的名字
