-- Create a group to act as the parent of the cube
vGroup = p3DMember.newGroup("Cube Base")
vGroup.addChild(vCube, #preserveWorld)
By default, the new group will be created at the center of the world, at vector(0, 0, 0). This vector now corresponds
to the center of the base of the Cube. Instead of moving and scaling the Cube, you can now move and scale the
group(“Cube Base”). This requires a small change in the code of the Group as Parent behavior.
Find these lines:
--===========================================================--
-- MAKE CHANGES HERE --
-- Prepare to move the cube... or the group
pMovableNode = vCube
--pMovableNode = vGroup -- REMOVE THE FIRST TWO -- CHARACTERS
--===========================================================--
Change these lines to:
--===========================================================--
-- MAKE CHANGES HERE --
-- Prepare to move the cube... or the group
--pMovableNode = vCube
pMovableNode = vGroup -- REMOVE THE FIRST TWO -- CHARACTERS
--===========================================================--
Now restart the movie and watch the cube as its scale changes. Click on the plane model, and drag the mouse pointer
around.
If you move and scale the Cube Base group, the Cube will remain sitting on the plane
This technique consists of three steps:
1 Creating a group.
2 Placing the group at the position that you want to use as the new origin point for the model.
3 Making the model a child of the group.
In this movie, step 2 was achieved by moving the model rather than by moving the group. See addChild() for more
information on the options for step 3.
Note: For more information on detecting the model under the mouse pointer, see “User interaction” on page 240.
