Camera class

Usage

active_cam.index

Description

Property (read-only); a zero-based integer that specifies the index of the camera, as reflected in 
the array returned by 

Example

The following example displays an array of cameras in a text field that is created at runtime, 
and tells you which camera you are currently using. Create a new video instance by selecting 
New Video from the Library options menu. Add an instance to the Stage and give it the 
instance name 

my_video

. Add a Label component instance to the Stage and give it the 

instance name 

camera_lbl

. Then add the following ActionScript to Frame 1 of the Timeline:

var camera_lbl:mx.controls.Label;
var my_cam:Camera = Camera.get();
var my_video:Video;
my_video.attachVideo(my_cam);

camera_lbl.text = my_cam.index+". "+my_cam.name;
this.createTextField("cameras_txt", this.getNextHighestDepth(), 25, 160, 

160, 80);

cameras_txt.html = true;
cameras_txt.border = true;
cameras_txt.wordWrap = true;
cameras_txt.multiline = true;
for (var i = 0; i<Camera.names.length; i++) {
    cameras_txt.htmlText += "<li><u><a 

href=\"asfunction:changeCamera,"+i+"\">"+Camera.names[i]+"</a></u></
li>";

}
function changeCamera(index:Number) {
    my_cam = Camera.get(index);
    my_video.attachVideo(my_cam);
    camera_lbl.text = my_cam.index+". "+my_cam.name;
}

The 

MovieClip.getNextHighestDepth()

 method used in this example requires Flash Player 

7 or later. If your SWF file includes a v2 component (version 2 of the Macromedia 
Component Architecture), use the DepthManager class from the component framework 
instead of the 

MovieClip.getNextHighestDepth()

 method.
