Method Details

attachChild

public int attachChild(Spatial child)

Description copied from class: Node

attachChild attaches a child to this node. This node becomes the child's parent. The current number of children maintained is returned.
If the child already had a parent it is detached from that former parent.

Overrides:

attachChild in class Node

Parameters:

child - the child to attach to this node.

Returns:

the number of children maintained by this node.

attachChildAt

public int attachChildAt(Spatial child,
 int index)

Description copied from class: Node

attachChildAt attaches a child to this node at an index. This node becomes the child's parent. The current number of children maintained is returned.
If the child already had a parent it is detached from that former parent.

Overrides:

attachChildAt in class Node

Parameters:

child - the child to attach to this node.

index - the index of the child to be attached.

Returns:

the number of children maintained by this node.

detachAllChildren

public void detachAllChildren()

Description copied from class: Node

detachAllChildren removes all children attached to this node.

Overrides:

detachAllChildren in class Node

detachChild

public int detachChild(Spatial child)

Description copied from class: Node

detachChild removes a given child from the node's list. This child will no longe be maintained.

Overrides:

detachChild in class Node

Parameters:

child - the child to remove.

Returns:

the index the child was at. -1 if the child was not in the list.

detachChildAt

public Spatial detachChildAt(int index)

Description copied from class: Node

detachChildAt removes a child at a given index. That child is returned for saving purposes.

Overrides:

detachChildAt in class Node

Parameters:

index - the index of the child to be removed.

Returns:

the child at the supplied index.

detachChildNamed

public int detachChildNamed(String childName)

Description copied from class: Node

detachChild removes a given child from the node's list. This child will no longe be maintained. Only the first child with a matching name is removed.

Overrides:

detachChildNamed in class Node

Parameters:

childName - the child to remove.

Returns:

the index the child was at. -1 if the child was not in the list.

draw

public void draw(Renderer r)

Description copied from class: Node

draw calls the onDraw method for each child maintained by this node.

Overrides:

draw in class Node

Parameters:

r - the renderer to draw to.

See Also:

• Spatial.draw(com.ardor3d.renderer.Renderer)

updateChildren

protected void updateChildren(double time)

Description copied from class: Spatial

Override to allow objects like Node to update their children.

Overrides:

updateChildren in class Node

Parameters:

time - The time in seconds between the last two consecutive frames (time per frame). See ReadOnlyTimer.getTimePerFrame()
