addChild
Syntax
member(whichCastmember
).node
(whichParentNode
).addChild(member(whichCastmember
).node
(whichChildNode
) {,#preserveWorld
})
Description
3D command; adds the node whichChildNode
to the list of children of the node whichParentNode
, and removes it from the list of children of its former parent. Either node
argument can be a model, group, camera, or light. An equivalent operation would be to set the parent
property of whichChildNode
to whichParentNode
.
The optional #
preserveWorld
parameter has two possible values: #preserveWorld
or #preserveParent
. When the child is added with #preserveParent
specified, the parent-relative transform of the child remains unchanged and the child jumps to that transform in the space of its new parent. The child's world transform is recalculated. When the child is added with #preserveWorld
specified, the world transform of the child remains unchanged and the child does not jump to its transform in the space of its new parent. Its parent-relative transform is recalculated.
Examples
This statement adds the model named Tire to the list of children of the model named Car.
member("3D").model("Car").addChild(member("3D").model("Tire"))
This statement adds the model named Bird to the list of children of the camera named MyCamera and uses the #preserveWorld
argument to maintain Bird's world position.
member("3D").camera("MyCamera").addChild(member("3D").model ("Bird"), #preserveWorld)
