Hope that anyone can helt me make a little action script,-
that take a “movie” and scale it from zero to 100%
Just like if u would do it with a “Motion Tween”.

onClipEvent(enterFrame) {
if(\_alpha \< 100) { //wrong code
\_alpha++; //wrong code
} //wrong code
} //wrong code
Add these actions to the movieclip (circle)!
make sure you set the alpha 0 too!

don’t you mean \_xScale and \_yScale, Syko?

I´ve found this code, andi works well,-
But how do i make it stop at a serten point.
Let´s say it has scailed the picture 150,- then i want it to stop.
onClipEvent (load)
{
z=0;
zspeed=5;
fl=10;
}
onClipEvent(enterFrame)
{
scale=fl/(fl+z);
\_xscale=\_yscale=150\*scale;
z-=zspeed;
}

onClipEvent(enterFrame)
{
if (\_xscale\<=150) {
scale=fl/(fl+z);
\_xscale=\_yscale=150\*scale;
z-=zspeed;
}
}

No more coffee to me!

You can use the easing equation inscalling. That way the scalling is smoother:
Make sure that the movie clip you want to scale has a smaller scale percentage than myXscale and myYscale.
```auto
onClipEvent(load){
//change these values to the amount in scalling percentage.
myXscale = 100;
myYscale = 100;
}
onClipEvent(enterFrame){
_xscale += (myXscale - _xscale)/3;
_yscale += (myYscale - _yscale)/3;
}
```

And there’s no need to calculate the focal length unless you want to do some more advanced perspective effects 🙂
```auto
onClipEvent(enterFrame)
{
if (_xscale<=150) {
_xscale=_yscale += 5 ;
}
}
```

Oh and that too! 😛
I thought there’s something wrong with my script… whew!

onClipEvent(enterFrame)
{
if (\_xscale\<=150) {
scale=fl/(fl+z);
\_xscale=\_yscale=150\*scale;
z-=zspeed;
}
}
what exactly does this code that jsk posted do? does it ease up to 150? or am i wrong

I´m all new to this Action script,-
and after getting all the results of this question, i´ve tryed to play around with this:
onClipEvent(enterFrame)
{
if (\_xscale\<=150) {
\_xscale=\_yscale += 5 ;
}
}
and changed it to this:
onClipEvent(enterFrame)
{
if (\_alpha\<=100) {
\_alpha -= 5 ;
}
}
It make a picture fade out,-
HOW do i make it fade out and then fade in???
No matter what i do i can´t make come back!!!

try this
[AS]
onClipEvent (load)
{
```
_alpha = 4;
```
reached100=false
}
onClipEvent (enterFrame)
```
{
```
if ((\_alpha\<100) and (reached100==false)){
\_alpha+=2;
}
else {
if(\_alpha!=0){
reached100=true
\_alpha-=2;
}
}
} [/AS]

If we’d just want to fade out and in, I’d do it like this:
```auto
MovieClip.prototype.fade_out_in = function()
{
this._alpha = 100;
direction = -1;
this.onEnterFrame = function()
{
if (this._alpha > 100 || this._alpha < 0)
{
if (direction == -1)
{
// At this point the photo is invisible
// So if you'd want you could change it ;P
direction = 1;
}
else delete this.onEnterFrame;
}
this._alpha += (2*direction);
}
}
photo_mc.fade_out_in();
```
