add your snow to a depth above your tree but below your logo.

var snowflakes:Array = new Array();
var snowflakeProps:Dictionary= new Dictionary(true);
var max_snowsize:Number = .04;
// pixels
var snowflakesCnt:Number = 900;
var oheight:Number;
var owidth:Number;
init();
function init():void {

          owidth = width;
          oheight = height;
          // quantity
          for (var i:int=0; i<snowflakesCnt; i++) {

                    var t:MovieClip = new SnowFlake();//
                    t.name = "snowflake"+i;

                    t.alpha = .2+Math.random()*.6;
                    t.x = -(owidth/2)+Math.random()*(1.5*owidth);
                    t.y = -(oheight/2)+Math.random()*(1.5*oheight);
                    t.scaleX = t.scaleY=.5+Math.random()*(max_snowsize*10);

                    snowflakeProps[t] = o;

                    addChild(t); // change this to something like addChildAt(t,1). you need to check the depth of your tree and logo to determine where to add your snow.
// or create an on-stage movieclip that's between your tree and logo and add the snow to that movieclip, like:
// middle_mc.addChild(t);
// and there are other ways to handle this.
                    snowflakes.push(t);

Thanks so much for replying.

Sorry, but I'm a Flash beginner and don't really understand

How can I check the depth of the tree and logo, since I didn't apply Actionscript to them?

I tried addChildAt(t,1), middle_mc.addChild(t), and an on-stage movie clip, but I'm pretty sure I'm doing it wrong.

Would you please be able to clarify?

Would posting the fla be beneficial?

Thanks a ton.

you can use getChildIndex() to check the depth of any display list object:

getChildIndex(your tree movieclip)

getChildIndex(your logo movieclip)

Where can I type getChildIndex() in?

Also, is there a way to add ActionScript to the tree and logo movieclips to easily layer them with the snow (1,2,3, etc.)

Thanks!

you can use:

addChildAt(your tree movieclip,0); // to position your tree bottom-most

// and every time you add some snow use:

addChild(t); // adds your snow on top of everything

addChild(your logo movieclip); // (re)adds your logo on top of everything

Flash is telling me that I can't place code directly on objects (for the logo) and there's no "Actions" option in the timeline for the logo movieclip.

How can I apply that Actionscript to the logo?

use:

addChild(your tree movieclip);

var snowflakes:Array = new Array();

var snowflakeProps:Dictionary= new Dictionary(true);

var max_snowsize:Number = .04;

// pixels

var snowflakesCnt:Number = 900;

var oheight:Number;

var owidth:Number;

init();

function init():void {

owidth = width;

oheight = height;

// quantity

for (var i:int=0; i<snowflakesCnt; i++) {

var t:MovieClip = new SnowFlake();//

t.name = "snowflake"+i;

t.alpha = .2+Math.random()*.6;

t.x = -(owidth/2)+Math.random()*(1.5*owidth);

addChild(t);

snowflakes.push(t);

addEventListener(Event.ENTER_FRAME, snowFlakeMover);

My tree movieclip is named Bitmap2 and my logo movieclips (actually in 4 pieces that fly together) are Object1, Object2, Object3, and Object4.

I'm getting an 1120 error (undefined property).

Here's what I've got so far (and I apologize for any errors I'm making here, I'm a beginner) :

addChild(Bitmap2);

var snowflakes:Array = new Array();

var snowflakeProps:Dictionary= new Dictionary(true);

var max_snowsize:Number = .04;

// pixels

var snowflakesCnt:Number = 900;

var oheight:Number;

var owidth:Number;

init();

function init():void {

owidth = width;

oheight = height;

// quantity

for (var i:int=0; i<snowflakesCnt; i++) {

var t:MovieClip = new SnowFlake();//

t.name = "snowflake"+i;

t.alpha = .2+Math.random()*.6;

t.x = -(owidth/2)+Math.random()*(1.5*owidth);

t.y = -(oheight/2)+Math.random()*(1.5*oheight);

t.scaleX = t.scaleY=.5+Math.random()*(max_snowsize*10);

var o:Object = new Object();

o.k = 1+Math.random()*2;

o.wind = -1.5+Math.random()*(1.4*3);

snowflakeProps[t] = o;

addChild(t);

addChild(Object1);

addChild(Object2);

addChild(Object3);

addChild(Object4);

snowflakes.push(t);

}

addEventListener(Event.ENTER_FRAME, snowFlakeMover);

}

function shakeUp():void{

for (var i:int=0; i<snowflakes.length; i++) {

var t:MovieClip = snowflakes[i] as MovieClip;

t.x = -(owidth/2)+Math.random()*(1.5*owidth);

t.y = -(oheight/2)+Math.random()*(1.5*oheight);

}

function snowFlakeMover(evt:Event):void {

var dO:MovieClip;

var o :Object;

if(visible && parent.visible){

for (var i:int = 0; i < snowflakes.length; i++) {

dO = snowflakes[i] as MovieClip;

o = snowflakeProps[dO];

dO.y += o.k;

dO.x += o.wind;

if (dO.y>oheight+10) {

dO.y = -20;

}

if (dO.x>owidth+20) {

dO.x = -(owidth/2)+Math.random()*(1.5*owidth);

dO.y = -20;

} else if (dO.x<-20) {

dO.x= -(owidth/2)+Math.random()*(1.5*owidth);

dO.y = -20;

}

Thanks a million.

right click whatever you think is Bitmap2, click convert to symbol, choose MovieClip and click ok. in the properties panel assign the instance name tree_mc.

shift-left click whatever your think is Object1,..,Object4 to select them all, right click, click convert to symbol, choose MovieClip and click ok. in the properties panel assign the instance name logo_mc.

remove the code you added and then add the following to confirm you followed the above steps correctly:

trace(tree_mc);

trace(logo_mc);
