Camera
Represents a Camera object.
A camera controls how a 3D sprite views the 3D world. A 3D sprite displays a particular camera’s
view into the world.
You can create a reference to a camera by using the
camera property of the 3D Member object.
The
camera property gets the camera at a specified index position in the list of cameras. In Lingo,
you use the
camera property directly from the 3D Member object to create a reference. In
JavaScript syntax, you must use the
getPropRef() method to create a reference.
The following example creates a reference to the second camera of the 3D cast member "family
room", and assigns it to the variable
myCamera.
-- Lingo syntax
myCamera = member("family room").camera[2]
// JavaScript syntax
var myCamera = member("family room").getPropRef("camera", 2);
