Gradual Zoom

[Butchee]

I have a somewhat complex image of a cartoon-like living room created in Flash. I want to zoom in on the room slowly, but tweening it is a bit jerky and slow, even when upping the fps. I've found posts regarding zooming on an image quickly using onClipEvent, for instance from 100% to 150%, but not gradually as in a motion tween. I'm new to Flash 5 and actionscripting, and would appreciate any help.

thanks...butchee

if you put this on your movieclip

onClipEvent (enterFrame) {
this._xscale = this._xscale+1;
this._yscale = this._yscale+1;
}

it will scale (or zoom) very gradually.

Need to be more specific as to when you want it to zoom etc....does it have to zoom out again??

cheers

if its runnning slowly its probably cos theres heaps of mcs in there, copy the mc's and paste in place, then break them up all the way and make it a graphic.

so you have:

the graphic plays from 100% to 150% and then the mc comes in and you can control it.

it will run much faster.

Thanks blue and Billy T. I used both suggestions and the zoom works great.

butchee :D

Hey Billy T,
The script is great, however, now my dilema is how to make it stop at a particular point. My first inclination was to use a stop action, but didn't work or I didn't do it properly. Any ideas on how to make this zoom stop?

try something like this:

onClipevent (load) {
zoomAmount = 50;
}

onClipEvent (enterFrame) {
if (zoomAmount > 0) {
this._xscale = this._xscale+1;
this._yscale = this._yscale+1;
zoomAmount = zoomAmount - 1;
}
}

Another cool thing to try is to have the zoom come to a gradual halt. you do this by setting your destination scale and then closing the distance by a fraction of the remaining distance:

onClipEvent (load) {
targetScale = 150;
}

onClipEvent (enterFrame) {
if (this._xscale < 150) {
this._xscale = this._xscale + (150 - this._xscale)/5
this._yscale = this._yscale + (150 - this._yscale)/5
}
}

BTW that code won't work if you copy and paste it, because it lacks terminating semicolons.

It works!

-- thanks for the code. i take it from your user name you may be a calvin & hobbes fan. if so, the new book, c&h sunday pages 1985-1995 is a must.

Sweet! Thanks for the heads up! I spent many a sunny Florida day sitting at the top of a tree reading Calvin and Hobbes as a kid. Waterson's one of my big illustration influences, too.

or u can stop the zooming by Billy's way

say you want the MC to aoom in to 150%


onClipEvent (enterFrame) {
this._xscale = this._xscale+1;
this._yscale = this._yscale+1;
if ((this._xscale >= 150) && this._yscale >= 150) {
this._xscale = 150;
this._yscale = 150;
}
}

How do you get this code to run more than once so you get a gradual zoom rather than it just executing once?:confused:
