MovieClip 491
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();
which traces the following information:
from current SWF file
dumpRoot -> [type Function]
$version -> WIN 7,0,19,0
nolockroot_mc -> _level0.nolockroot_mc
lockroot_mc -> _level0.lockroot_mc
from nolockroot.swf
myVar -> 1
i -> lockroot_mc
dumpRoot -> [type Function]
$version -> WIN 7,0,19,0
nolockroot_mc -> _level0.nolockroot_mc
lockroot_mc -> _level0.lockroot_mc
from lockroot.swf
myOtherVar -> 2
myVar -> 1
The file with no _lockroot applied also contains all of the other variables that the root SWF
file contains. If you don't have access to the nolockroot.fla, you can use the following
ActionScript added to the main Timeline to change the
_lockroot in the preceding main
FLA document:
this.createEmptyMovieClip("nolockroot_mc", this.getNextHighestDepth());
nolockroot_mc._lockroot = true;
nolockroot_mc.loadMovie("nolockroot.swf");
