if (dragToRotate){
if (canRotate){
// value = -value;

示例2: calculateNewForward
import com.jme3.math.Quaternion; //导入方法依赖的package包/类
/**

* the direction, this method sets the priority on the up vector so that the result
* direction vector and rotation is guaranteed to be perpendicular to the up vector.
*
* @param rotation The rotation to set the result on or null to create a new
* Quaternion, this will be set to the new "z-forward" rotation if not null
* @param direction The direction to base the new look direction on, will be set to
* the new direction
* @param worldUpVector The up vector to use, the result direction will be
* perpendicular to this
* @return
