[OpenLayers-Users] animated markers

[Vito Tafuni]

hi Carlo

i'm working on vector layer because it seems to be the right solution.
at the moment i'm drawing a custom (vector) marker and the next step will be
to find a way to animate it (and to show the popup window inside it).

this is the initial code i've wrote to draw a shape on a map
                    var point = e.xy;

                    var markerTemplate = [
                        point,
                        point.offset(new OpenLayers.Pixel(100,0)),
                        point.offset(new OpenLayers.Pixel(100,100)),
                        point
                    ];

                    for(i=0; i<markerTemplate.length; i++){
                        markerTemplate[i] =
map.getLonLatFromViewPortPx(markerTemplate[i]);
                        markerTemplate[i] = new
OpenLayers.Geometry.Point(markerTemplate[i].lon,markerTemplate[i].lat);
                    }

                    var style_mark = OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);
                    style_mark.graphicWidth = 24;
                    style_mark.graphicHeight = 20;
                    style_mark.graphicXOffset = 10; // default is
-(style_mark.graphicWidth/2);
                    style_mark.graphicYOffset = -style_mark.graphicHeight;
                    // graphicTitle only works in Firefox and Internet
Explorer
                    style_mark.graphicTitle = "this is a test tooltip";


                    var feature = new OpenLayers.Feature.Vector(new
OpenLayers.Geometry.Polygon(new
OpenLayers.Geometry.LinearRing(markerTemplate)),null,style_mark);

but i've changed it with this
                   OpenLayers.Renderer.symbol.marker = [0,0, 0,-100,
100,-100, 0,0];
                   var style_mark = OpenLayers.Util.extend({},
OpenLayers.Feature.Vector.style['default']);
                   style_mark.graphicName='marker';
                   style_mark.pointRadius=10;

                   var point = map.getLonLatFromViewPortPx(e.xy);
                   var feature = new OpenLayers.Feature.Vector(new
OpenLayers.Geometry.Point(point.lon,point.lat),null,style_mark);

because i wanted a fixed size marker  respect to the zoom level of the map


if someone know how to animate the mark (i've seen a Tween class but i had
no time to experiment!) please write down a link or a sample code!!

Vito
