MovieClip._lockroot
Availability
Flash Player 7.
Usage
my_mc._lockroot
Description
Property; specifies what _root refers to when a SWF file is loaded into a movie clip. The
_lockroot property is undefined by default. You can set this property within the SWF file that
is being loaded or in the handler that is loading the movie clip.
For example, suppose you have a document called Games.fla that lets a user choose a game to
play, and loads the game (for example, Chess.swf ) into the
game_mc movie clip. You want to make
sure that, if
_root is used in Chess.swf, it still refers to _root in Chess.swf after being loaded into
Games.swf. If you have access to Chess.fla and publish it to Flash Player 7 or later, you can add
this statement to it:
this._lockroot = true;
If you don’t have access to Chess.fla (for example, if you are loading Chess.swf from someone
else’s site), you can set its
_lockroot property when you load it, as shown below. In this case,
Chess.swf can be published for any version of Flash Player, as long as Games.swf is published for
Flash Player 7 or later.
onClipEvent (load)
{
this._lockroot = true;
}
game_mc.loadMovie ("Chess.swf");
If you didn’t use the this._lockroot = true statement in either of the SWF files, _root in
Chess.swf would refer to
_root in Games.swf after Chess.swf is loaded into Games.swf.
