startDrag function

startDrag(target:Object, [lock:Boolean, left:Number, top:Number, right:Number, bottom:Number]) : Void

Makes the target movie clip draggable while the movie plays. Only one movie clip can be dragged at a time. After a startDrag() operation is executed, the movie clip remains draggable until it is explicitly stopped by stopDrag() or until a startDrag() action for another movie clip is called.

Availability: ActionScript 1.0; Flash Player 4

Parameters

target:Object - The target path of the movie clip to drag.

lock:Boolean [optional] - A Boolean value specifying whether the draggable movie clip is locked to the center of the mouse position (true ) or locked to the point where the user first clicked the movie clip (false ).

left,top,right,bottom:Number [optional] - Values relative to the coordinates of the movie clip's parent that specify a constraint rectangle for the movie clip.

Example

The following example creates a movie clip, pic_mc, at runtime that users can drag to any location by attaching the startDrag() and stopDrag() actions to the movie clip. An image is loaded into pic_mc using the MovieClipLoader class.

var pic_mcl:MovieClipLoader = new MovieClipLoader();
pic_mcl.loadClip("http://www.helpexamples.com/flash/images/image1.jpg",
 this.createEmptyMovieClip("pic_mc", this.getNextHighestDepth()));
var listenerObject:Object = new Object();
listenerObject.onLoadInit = function(target_mc) {
 target_mc.onPress = function() {
 startDrag(this);
 };
 target_mc.onRelease = function() {
 stopDrag();
 };
};
pic_mcl.addListener(listenerObject);
