on GetRelativeTransform(aNode, aTargetNode)
vTargetTransform = aTargetNode.getWorldTransform()
vFrameOfReference = aNode.parent.getWorldTransform()
vInverse = vFrameOfReference.inverse()
vRelativeTransform = vInverse * vTargetTransform
return vRelativeTransform
end GetRelativeTransform
An alternative approach is to change the parent of the big blue cone twice. Try the following commands in the Message
window:
-- Lingo syntax
v3DMember = member("3D")
vTarget = v3DMember.model("Red3")
vModel = v3DMember.model("Blue3")
vParent = vModel.parent
vModel.parent = v3DMember.group("World")
vModel.transform = vTarget.getWorldTransform()
vParent.addChild(vModel, #preserveWorld)
// JavaScript syntax
v3DMember = member("3D");
vTarget = v3DMember.getPropRef("model", 3);
vModel = v3DMember.getPropRef("model", 6);
vParent = vModel.parent;
vModel.parent = v3DMember.getPropRef("group", 1);
vModel.transform = vTarget.getWorldTransform();
vParent.addChild(vModel, symbol("preserveWorld"));
userData
All nodes have a property list named userData attached to them.
-- Lingo syntax
put member("3D").model(1).userData
-- [:]
// JavaScript syntax
trace(member("3D").getPropRef("model", 1).userData);
//
Permanence of the contents of the userData list
Depending on the third-party 3D design software used, your 3D designer may be able to add data to the userData lists
of the various nodes when exporting the 3D world to W3D format. In this case, that data will be available to you
permanently both during authoring and at runtime.
In Director 11.5, any data that you add to a node's userData list while authoring will not be saved with the 3D world,
even if you use the member3D.saveWorld() command first. In other words, changes made to a node's userData list
are available only for the current session.
In Director 11.5, you cannot set the userData list to a Lingo property list. This provokes an "Access not supported"
script error. To change the contents of the userData list, you must act directly on the built-in list.
Also, in Director 11.5, you cannot use bracket access to get or set values in the userData list. If you try to set a value
for bracket access, a script error occurs (Access not supported). When you use bracket access to retrieve a value, a
pointer to the entire list is returned. However, you can create a pointer to the list and use all the standard list methods
on that.
When working directly on a Node.userData lists, some standard list methods are not supported.
