Action Script 3.0 from 2.0 Falling Randomly Placed Objects and a countdown timer - actionscript

Question

Looking for some help on a lesson I teach to my pupils in Flash Animation.
Not overly familiar with the code, I can essentially do this one thing
I have four layers on my animation. Background, snow, timer and action script.
I have the following code on my snow layer (which has a simple oval in white on it)
onClipEvent (load) {
movieWidth=550;
movieHeight=400;
i=1+Math.random()*2;
k = -Math.PI+Math.random()*Math.PI;
this._xscale = this._yscale=50+Math.random()*100;
this._alpha = 60+Math.random()*100;
this._x = -10+Math.random()*movieWidth;
this._y = -10+Math.random()*movieHeight;
}
onClipEvent (enterFrame){
rad += (k/180)*Math.PI;
this._x -= Math.cos(rad);
this._y += i;
if(this._y>=movieHeight){
this._y = -5;
}
if((this._x>=movieWidth) || (this._x<=0)){
this._x = -10+Math.random()*movieWidth;
this._y = -5;
}
}
and this on my action script layer
this.onEnterFrame = function()
{
var today:Date = new Date();
var currentYear = today.getFullYear();
var currentTime = today.getTime();
var targetDate:Date = new Date(currentYear, 11, 25);
var targetTime = targetDate.getTime();
var timeLeft = targetTime - currentTime();
var sec = Math.floor(timeLeft/1000);
var min = Math.floor(sec/60);
var hours = Math.floor(min/60);
var days = Math.floor(hours/24);
sec = String(sec % 60);
if(sec.length < 2){
sec = "0" + sec;
}
min = String(min % 60);
if(min.length < 2){
min = "0" + min;
}
hours = String(hours % 24);
if(hours.length < 2){
hours = "0" + hours;
}
days = String(days)
var counter:String = days + " Days\n" + hours + ":" + min + ":" + sec;
time_txt.text = counter;
}
for (k=0; k<100; k++){
duplicateMovieClip(this.snow, "snow"+k, k);
}
I know this worked previously in AS2, but I have trouble getting it to work.
Currently getting a syntax error which wasn't there when I used an older version
Any help is much appreciated
Thanks

Answer 1

You are using flash player 6 syntax with flash player 5 elements (onClipEvent() handlers assignable to movieclips on the timeline). I don't think one could possibly expect to see something like that now... As it started getting outdated by late 2001, when FP 6 with (almost) fully ECMA262-compliant ActionScript 1.0 emerged.
Anyway, you can compile it after setting File -> Publish Settings... -> Script option to ActionScript 1.0 or ActionScript 2.0. Your code does work this way, I copied and pasted it to make sure. Be carefull to place the onClipEvent() code on the snow clip and not on the timeline frame. This is the FP5 way of handling events. And the rest of the code goes to timeline frame (I guess this is what you did).
You may also need to change target Flash Player version in case your IDE doesn't allow you to set script version to 1.0 without that (with Flash Pro CS6 this is not the case).
Working example (open in CS5 or newer): snowCS5.fla
