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);
}
