[FONT=Times New Roman][SIZE=3]I’ve been looking through documentation, and on the forums, and am hopelessly confused with some of the new things in AS3. I have tried **include** , **import** , and **class paths** to no avail. Anyway…[/SIZE][/FONT]

[FONT=Times New Roman][SIZE=3]_Folder1\Scripts\PhysicsEngine.as // class_[/SIZE][/FONT]

[FONT=Times New Roman][SIZE=3] **Class AS file:** [/SIZE][/FONT]

```auto
 class PhysicsEngine {
            private var age:int;
 
            public function PhysicsEngine(newAge:int) {
                        age = newAge;
                        trace("PhysicsEngine created.");
                        trace("age = " + age + ".");
            }
}

```

[FONT=Times New Roman][SIZE=3] **test fla, frame 1:** [/SIZE][/FONT]

```auto
var myEngine:PhysicsEngine = new PhysicsEngine(10);

[FONT=Times New Roman][SIZE=3]Just what is wrong with this code? I have a class path set up which is supposed to be importing the “Scripts” folder into frame 1.[/SIZE][/FONT]

[FONT=Times New Roman][SIZE=3] **I also get a nasty error: Cannot open a protected movie.** [/SIZE][/FONT]
