FLASH® LITE™ 2.x - Adobe Help and Support

Example
In the following example, lockroot.fla has _lockroot applied to the main SWF file. If the
SWF file is loaded into another FLA document, _root always refers to the scope of
lockroot.swf, which helps prevent conflicts. Place the following ActionScript on the main
Timeline of lockroot.fla:
this._lockroot = true;
_root.myVar = 1;
_root.myOtherVar = 2;
trace("from lockroot.swf");
for (i in _root) {
trace(" "+i+" -> "+_root[i]);
}
trace("");
which traces the following information:
from lockroot.swf
myOtherVar -> 2
myVar -> 1
_lockroot -> true
$version -> WIN 7,0,19,0
The following example loads two SWF files, lockroot.swf and nolockroot.swf. The
lockroot.fla document contains the ActionScript from the preceding example. The nolockroot
FLA file has the following code placed on Frame 1 of the Timeline:
_root.myVar = 1;
_root.myOtherVar = 2;
trace("from nolockroot.swf");
for (i in _root) {
trace(" "+i+" -> "+_root[i]);
}
trace("");
The lockroot.swf file has _lockroot applied to it, and nolockroot.swf does not. After the files
are loaded, each file dumps variables from their _root scopes. Place the following
ActionScript on the main Timeline of a FLA document:
this.createEmptyMovieClip("lockroot_mc", this.getNextHighestDepth());
lockroot_mc.loadMovie("lockroot.swf");
this.createEmptyMovieClip("nolockroot_mc", this.getNextHighestDepth());
nolockroot_mc.loadMovie("nolockroot.swf");
function dumpRoot() {
trace("from current SWF file");
for (i in _root) {
trace(" "+i+" -> "+_root[i]);
}
trace("");
}
dumpRoot();
