Town view magnifying glass: redundant?

Yes the magnifying glass slows down my crappy laptop too, it would be much smoother without it, not that i ever feel it's necessary anyway. :)

Using Greasemonkey, there are two ways you can fix the zoom.


Try to improve the performance by rewriting the code:

        document.townZoomX = 0;
        document.townZoomY = 0;
        document.townMapNode = document.getElementById("townMap");
        unsafeWindow.mapZoomMove = function(evt) {
            var offsetX = document.all ? evt.offsetX : evt.pageX - document.townMapNode.offsetLeft;
            var offsetY = document.all ? evt.offsetY : evt.pageY - document.townMapNode.offsetTop;
            document.townZoomY = parseInt(offsetY) * 2;
            document.townZoomX = parseInt(offsetX) * 2;
        }
       
        unsafeWindow.mapZoomRefresh = function() {
            var x = document.townZoomX;
            var y = document.townZoomY;
            var ctrl = document.getElementById("mapZoom");
            ctrl.style.top = (-515 - y) + 'px';
            ctrl.style.left = (-32 - x) + 'px';
            ctrl.style.clip = "rect(" + y + "px " + (x + 163) + "px " + (y + 163) + "px " + x + "px)";
        }

        setInterval(unsafeWindow.mapZoomRefresh, 50);

(Increase the number in setInterval to reduce cpu usage at the cost of choppy panning.  If the number is sufficiently large to spare a few cpu cycles, the building borders will at least hover-highlight responsively, so you can tell when you're going to click on the right item without waiting.)


Or simply remove it from the page:

        getNode("/html/body/table[2]/tbody/tr[2]/td/table/tbody/tr[2]/td/div").innerHTML = "";
        unsafeWindow.mapZoomMove = function(evt) { return; }


Your mileage will vary with the first method.  For some, it won't help at all.  What's being attempted by that part of the page and the work required to accomplish it simply isn't reasonable for software rendering in this context.  Coupled with a little code that turns building tooltips into hover displays that popup instantly, I'm quite happy with the removal.

Also, if you're finding Firefox having huge overall performance issues that you never encountered before, this may help.  Illyriad's interface seems to slaughter FF like nothing else that I've seen, and I used to keep scores of tabs open at a time.
