  • Constructor Details

    • Box2dShape

      protected Box2dShape()
      No-argument constructor needed by SavableClassUtil.

    • Box2dShape

      public Box2dShape(float halfExtent)
      Instantiate a square shape with the specified half extent.
      Parameters:
      halfExtent - the desired unscaled half extent on each local axis (not negative)

    • Box2dShape

      public Box2dShape(float xHalfExtent, float yHalfExtent)
      Instantiate a rectangle shape with the specified half extents.
      Parameters:
      xHalfExtent - the desired unscaled half extent on the local X axis (not negative)
      yHalfExtent - the desired unscaled half extent on the local Y axis (not negative)

    • Box2dShape

      public Box2dShape(com.jme3.math.Vector2f halfExtents)
      Instantiate a rectangle shape with the specified half extents.
      Parameters:
      halfExtents - the desired unscaled half extents (not null, no negative component, unaffected)

    • Box2dShape

      public Box2dShape(com.jme3.math.Vector3f halfExtents)
      Instantiate a rectangle shape with the specified half extents.
      Parameters:
      halfExtents - the desired unscaled half extents (not null, no negative component, unaffected, Z component ignored)

  • Method Details

    • getHalfExtents

      public com.jme3.math.Vector3f getHalfExtents(com.jme3.math.Vector3f storeResult)
      Copy the half extents of the rectangle.
      Parameters:
      storeResult - storage for the result (modified if not null)
      Returns:
      the unscaled half extent for each local axis (either storeResult or a new vector, not null, no negative component)

    • cloneFields

      public void cloneFields(com.jme3.util.clone.Cloner cloner, Object original)
      Callback from Cloner to convert this shallow-cloned shape into a deep-cloned one, using the specified Cloner and original to resolve copied fields.

      cloneFields in interface com.jme3.util.clone.JmeCloneable
      Overrides:
      cloneFields in class CollisionShape
      Parameters:
      cloner - the Cloner that's cloning this shape (not null)
      original - the instance from which this shape was shallow-cloned (not null, unaffected)

    • maxRadius

      public float maxRadius()
      Calculate how far the scaled shape extends from its center.
      Overrides:
      maxRadius in class CollisionShape
