_level
Availability
Flash Player 4.
Usage
_levelN
Description
Identifier; a reference to the root Timeline of _levelN. You must use loadMovieNum() to load
SWF files into the Flash Player before you use the
_level property to target them. You can also
use
_levelN to target a loaded SWF file at the level assigned by N.
The initial SWF file loaded into an instance of the Flash Player is automatically loaded into
_level0. The SWF file in _level0 sets the frame rate, background color, and frame size for all
subsequently loaded SWF files. SWF files are then stacked in higher-numbered levels above the
SWF file in
_level0.
You must assign a level to each SWF file that you load into the Flash Player using
loadMovieNum(). You can assign levels in any order. If you assign a level that already contains a
SWF file (including _level0), the SWF file at that level is unloaded and replaced by the new
SWF file.
Example
The following example stops the playhead in the main Timeline of the SWF file in _level9.
_level9.stop();
The following example sends the playhead in the main Timeline of the SWF file in _level4 to
Frame 5. The SWF file in
_level4 must have previously been loaded with a loadMovieNum()
action.
_level4.gotoAndStop(5);
