本文整理了Java中com.jme3.scene.Spatial类的一些代码示例，展示了Spatial类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Spatial类的具体详情如下：
包路径：com.jme3.scene.Spatial
类名称：Spatial

Spatial介绍

[英]Spatial defines the base class for scene graph nodes. It maintains a link to a parent, its local transforms and the world's transforms. All other scene graph elements, such as Node and Geometry are subclasses of Spatial.
[中]Spatial定义场景图节点的基类。它维护到父级、其局部变换和世界变换的链接。所有其他场景图形元素（如节点和几何体）都是Spatial的子类。

代码示例

private void fixRefreshFlags(){
  // force transforms to update below this node
  spatial.updateGeometricState();
  
  // force world bound to update
  Spatial rootNode = spatial;
  while (rootNode.getParent() != null){
    rootNode = rootNode.getParent();
  }
  rootNode.getWorldBound(); 
}
