Parameters Target - Identifies the movie clip to be dragged.
Boundary - These fall under the constrain to rectangle parameter and are the max. distances (in the four directions) from the centerpoint of the movie clip's parent where dragging can occur. (pixels) Lockcenter - If the option is checked then the movie clip will center on the pointer when clicked. If left unchecked the movie clip will remain in a position relative to the mouse click. Stop Drag - Check if identifying mouse events that will stop dragging the target.
Example uses:
Games, shopping baskets or anywhere you need a drag and drop function.
Description:
This action should be used in an On (Press) mouse event, ie when the mouse button is press but not released). To use it you must first define the target you wish to drag. The next if you do not check the constrain to rectange option, your movie will be free to be dragged anywhere in the flashplayer's window. However if you do check it then you must define the four boundaries that will restrict the dragging. The final option in the Start Drag Action is Lockcenter it functions have already been covered in the parameters section above.
Every start as a stop and to stop dragging requires and new mouse event. This generally covers Release, Release Outside and Roll Out to cover all bases. To place the action simply check the Stop Drag option in the parameters field. (see the example below).
