But you could just write it this way:
class MyClass extends MovieClip {
private var foo:Boolean = false;
public function MyClass() {
}
public function traceFoo() {
trace(foo);
}
private function onEnterFrame():Void {
foo = !foo;
traceFoo();
}
}
Or even like this:
class MyClass extends MovieClip {
private var foo:Boolean = false;
public function MyClass() {
onEnterFrame = toggleAndTraceFoo;
}
public function traceFoo() {
trace(foo);
}
private function toggleAndTraceFoo():Void {
foo = !foo;
traceFoo();
}
}
(Me, I prefer to use an event dispatcher that sends "enterFrame" events,
but I'll admit that that's often overkill.)
