Okay, up to this point we've only talked about everything that's different between the two versions of ActionScript. But what about them is the same? What hard-earned knowledge of ActionScript 1.0 that you currently have is still applicable to ActionScript 2.0? Fortunately, plenty!
You still control movie clips with this syntax:
myMovieClip_mc.gotoAndPlay(15);
You still create conditional statements the same way:
if (myNumber1 + myNumber2 == 20 && enabled != true){ //actions; }
or looping statements this way:
for (i = 0; i <= myVariable; ++i){ //actions; }
Expressions are still created the same way:
myVariable = (myNumber1 / 2) + (myNumber2 + 15);
And scripts can still be assigned to button and movie clip instances using the on() and onClipEvent() event handlers.
