Zoom+Pan

[MLVR]

Hey,

I've read the threads regarding this topic, but i haven't found any that explains how to zoom and pan within a 'frame' on mouse over, there's always a button or slider to zoom and you always have to click and drag to pan.

Does any one know any tutorials covering this?


...move mouse over left part of picture and it zooms in and pans left, move mouse over righ part and it zooms and pans towards right, etc...

found this: http://www.flashkit.com/board/showth...light=pan+zoom ericlins example is similiar to what i want but i also want zoom!

Thanks guys!

If this is close to what you're looking for....

(It's a map scroller that uses mouse over for pan & zoom, and has annotated zoom positions).

...I can modify it to work within a frame (using a mask).

Hi Jbum,

Is there anychance you could link to the fla file again as the link shown above is not working.

This script is perfect for what we want to do with our local community website and I would love to be able to look through the fla and see how it works.

I would happily post credits to yourself as the creator if we use it.

here you have the source: http://sterics.f2o.org/map_mover.fla

also, I want to ask for help: I need this same effect but without pan.

I have a map with different landmarks, when you pass the mouse over the landmarks the map should zoom in keeping the landmark in the center (obviously on mouse out it should zoom out).

Any suggestions would be very much apreciated! Thanks!

Now to add a caviat!

I am trying to make a pan/zoom thing with the following: I'd like to take a map of my county in a box, and allow you to pan around the map, BUT when the mouse goes over an object or a word, I'd like a description / picture to pop up on the left of the map. I don't care how the user pans around - I guess up-down/right-left arrows are the best, but when the mouse goes over or clicks on a road name, I'd like to have a little description box pop up outside of the map.

Any tutorials? Does everyone hate me for asking this? I don't think Zoom would be too necessary.

[Mackheath1]

I'm responding to myself..

Basically, I want to be able to do this: http://justinsimoni.com/projects/lafayette/map.html but not even that elaborate. Just pan the map around, zoom in and out maybe, and when the mouse goes over a road label, I can display information about the road on the right.

try this inside of a button

on (press) {
speed = 95;
movie._x -= speed;
}


***Subsitute 'movie' for the Instance name of the object that needs to move.

[Mackheath1]

Thanks! I'll give that a try! I appreciate the help, and I'll let you know how it turns out.

[alloykid]

try this inside of a button

on (press) {
speed = 95;
movie._x -= speed;
}

Also note that by changing the "-" to a "+" will change direction that it moves the object. And by using a movie._Y would produce up and down movment.

That's all kinda common sense info.. but didn't want to leave you hanging if you didn't know.

Let me know how it works.

Does anyone know how to convert this code to use a mouse click and centers map at zoomed level? [SAME ZIP FILE AS ABOVE].

_______________

// size of stage
SW = Stage.width;
SH = Stage.height;

// size of large map
MW = map_mc._width;
MH = map_mc._height;

// Movement speed
SPEED = .2;

// Points of Interest
// x,y radius, name
poi = [{x:971,y:54,r:60,n:"Grace Cathedral"},
{x:461,y:502,r:80,n:"Moscone Center"},
{x:311,y:384,r:64,n:"Union Square"},
{x:665,y:146,r:64,n:"World Trade Center"},
{x:428,y:148,r:64,n:"Transamerica Bldg"}
];

// Zoom-in Amount
zoomAmt = 100; // additional zoom
feedback_txt.autoSize = true;

// This function keeps the target centered on zero,zero on submap_mc.
// This is done so that when we zoom, the zoom stays centered around
// the target
//
map_mc.submap_mc.onEnterFrame = function()
{
mapx = MW*_root._xmouse/SW;
mapy = MH*_root._ymouse/SH;
this.tx = 0 - mapx;
this.ty = 0 - mapy;
// _root.feedback_txt.text = mapx + ", " + mapy;
this._x += (this.tx-this._x)*SPEED;
this._y += (this.ty-this._y)*SPEED;
// for 'exact' positioning, use this instead
// this._x = this.tx;
// this._y = this.ty;
}

// This keeps the map centered under the mouse
// and scales it based on proximity to Moscone center
map_mc.onEnterFrame = function()
{
this._x = _root._xmouse;
this._y = _root._ymouse;

var dx = zoomX - mapx;
var dy = zoomY - mapy;

// find a nearby point of interest
var p = -1;
var dist;
for (var i = 0; i < poi.length; ++i)
{
var dx = poi[i].x - mapx;
var dy = poi[i].y - mapy;
dist = Math.sqrt(dx*dx+dy*dy);
if (dist < poi[i].r) {
p = i;
break;
}
}
if (p != -1) // did we get one? zoom in & show the name
{
var zoom = 100+zoomAmt-zoomAmt*dist/poi[p].r;
this._xscale = this._yscale = zoom;
feedback_txt.text = poi[p].n;
}
else { // otherwise, don't zoom in
this._xscale = this._yscale = 100;
feedback_txt.text = "";
// uncomment the following line to see the coordinates
feedback_txt.text = Math.floor(mapx) + ", " + Math.floor(mapy);
}
};

i only need to add pan controls to my map using actionscript 3.0 does any one can help me with that thnx

[maryacallahan]

I have a file that uses pan and zoom but it is in AS 2. you may be able to interpret it. File is too large to attach but I'm happy to send you the AS or if you need the file I can send it privately.

[morkus_2]

Yes please send it to me on morkus_2@hotmail.com
