detection

I've been doing web development for years now and I'm slowly getting myself involved with game development and for my current project I've got this isometric map, where I need to use an algorithm to detect which field is being clicked on. This is all in the browser with Javascript by the way. The map It looks like this and I've added some numbers to show you the structure of the fields (tiles) and their IDs. All the fields have a center point (array of x,y) which the four corners are based on when drawn. As you can see it's not a diamond shape, but a zig-zag map and there's no angle (top-down

I am trying to figure out how to detect which Taskbar button was clicked. Specifically, I want to write a script that makes it possible to maximize a window by double-clicking its Taskbar button. That requires knowing which Taskbar button was clicked, which I am having a difficult time finding any leads on. Does anyone know how this can be accomplished? That's a though one I have to admit. I can't offer you a best practice solution, but here is a little work around, maybe that enough for your purposes: CoordMode, Mouse, Screen ~LButton:: If (A_TimeSincePriorHotkey<400) and (A_PriorHotkey="

I am working on a project which requires detection of people in a scene. Initially after running the HOG detector on the original frames a particular background object was being detected as a person on all the frames, giving me 3021 false positive detections. So I took the logical step to remove the static background by applying a background subtracter (BackgroundSubtractorMOG2) to all the frames. The resulting frames looked like this: Then these mask images were added (using bitwise_and) to the original image so the white pixels are replaced the pixels constituting the person. Sample: Then I

There are several email servers refusing connections of clients with public dynamic IP addresses. For example many smtp servers receiving emails only accept connections to clients having static IP adresses to avoid spam emails which are directly sent from computers having dynamic IP addresses. When I looked for answers using google I only found information saying it is impossible to distinguish between static/dynamic addresses. So how do the email servers do it? Are there any databases providing information for specific IP ranges? Have a look at the MX records of t-online.de (one of the

Possible Duplicate: Determine whether client browser has java installed and can launch applets I would like to run a check to see whether Java is not installed or if it's disabled / blocked in IE. I have tried navigator.javaEnabled() and this works as expected in Firefox (v10.0.2), but in IE8 it returns TRUE. However, IE displays a prompt to the user: The page you are viewing uses Java. More information on Java support is available from the Microsoft website. The issue I have with this is, there is a checkbox "Do not show this message again" that can obviously be ticked and then there would no

How to detect user's click on the link inside the iframe using JavaScript? You are able to check iframe load event onLoad="alert(this.contentWindow.location);" or on jquery: $('iframe#yourId').load(function() { alert("the iframe has been loaded"); }); Assuming you have an iframe with ID "myIframe", and the iframe comes from the same domain as the main document, the following will detect a click anywhere in the document. This will also work when the document is editable, which using the document's onclick property would not: function iframeClickHandler() { alert("Iframe clicked"); } var iframe
