Do you mean that setting the associated AS 2.0 class in the
MovieClip's linkage settings is not an option and you want to alter
the class of an existing MovieClip instance at run-time? It's possible
by utilizing the __proto__ property and reorganizing the prototype
chain.
But your code seems to be not optimal:
1. unnecessary and superfluous to create a wrapper function for each
instance's onRelease handler (it creates as many Function instances
as many blah instance is created)
2. the same with setting the handler function in the constructor,
since it can be a simple class member
class blah extends MovieClip {
private function onRelease(): Void {
// handle release here
}
}
