Spatial.setLocalRotation介绍

[英]setLocalRotation sets the local rotation of this node by using a Matrix3f.
[中]setLocalRotation使用Matrix3f设置此节点的局部旋转。

代码示例

代码示例来源：origin: jMonkeyEngine/jmonkeyengine

Quaternion rotation = new Quaternion();
rotation.fromAngleNormalAxis(angle, Vector3f.UNIT_Y);
floor.setLocalRotation(rotation);
sky.setLocalRotation(rotation);

代码示例来源：origin: jMonkeyEngine/jmonkeyengine

Quaternion q = new Quaternion();
  q.lookAt(direction, upVector);
  spatial.setLocalRotation(q);
  break;
case LookAt:
    q2.lookAt(direction, upVector);
    q2.multLocal(rotation);
    spatial.setLocalRotation(q2);
    spatial.setLocalRotation(rotation);
