  • I can't figure out why this fps counter is inaccurate.

    - by rmetzger
    I'm trying to track frames per second in my game. I don't want the fps to show as an average. I want to see how the frame rate is affected when I push keys and add models etc. So I am using a variable to store the current time and previous time, and when they differ by 1 second, then I update the fps. My problem is that it is showing around 33fps but when I move the mouse around really fast, the fps jumps up to 49fps. Other times, if I change a simple line of code elsewhere not related to the frame counter, or close the project and open it later, the fps will be around 60. Vsync is on so I can't tell if the mouse is still effecting the fps. Here is my code which is in an update function that happens every frame: FrameCount++; currentTime = timeGetTime (); static unsigned long prevTime = currentTime; TimeDelta = (currentTime - prevTime) / 1000; if (TimeDelta > 1.0f) { fps = FrameCount / TimeDelta; prevTime = currentTime; FrameCount = 0; TimeDelta = 0; } Here are the variable declarations: int FrameCount; double fps, currentTime, prevTime, TimeDelta, TimeElapsed; Please let me know what is wrong here and how to fix it, or if you have a better way to count fps. Thanks!!!!!! I am using DirectX 9 btw but I doubt that is relevant, and I am using PeekMessage. Should I be using an if else statement instead? Here is my message processing loop: MSG msg; ZeroMemory (&msg, sizeof (MSG)); while (msg.message != WM_QUIT) { if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) { TranslateMessage (&msg); DispatchMessage (&msg); } Update (); RenderFrame (); }

  • Is enemy / bot A.I. part of the model or controller in an MVC game

    - by Iain
    It could be part of the model because it's part of the business logic of the game. It could be part of the controller because it could be seen as simulating player input, which would be considered part of the controller, right? Or would it? What about a normal enemy, like a goomba in Mario? UPDATE: Wow, that's really not the answer I was expecting. As far as I could tell, A.I. is an internal part of the autonomous game system, hence model. I'm still not convinced.

  • Mac vs. Windows Browser Font Height Rendering Issue

    - by cdmckay
    I'm using a custom font and the @font-face tag. In Windows, everything looks great, regardless of whether it's Firefox, Chrome, or IE. On Mac, it's a different story. For some reason, the Mac font renderer thinks the font is a lot shorter than it is. For example, consider this test code (live example here): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Webble</title> <style type="text/css"> @font-face { font-family: "Bubbleboy 2"; src: url("bubbleboy-2.ttf") format('truetype'); } body { font-family: "Bubbleboy 2"; font-size: 30px; } div { background-color: maroon; color: yellow; height: 100px; line-height: 100px; } </style> </head> <body> <div>The quick brown fox jumped over the lazy dog.</div> </body> </html> Open it on Windows Firefox and on Mac Firefox. Use your mouse to select it. On Windows, you'll notice it fully selects the font. On Mac, it only selects about half the font. If you look at what it is selecting, you'll see that that part has been centered, instead of the full height of the font. Is there anyway to fix this rather large discrepancy?

  • Touching an object in a tweened animation?

    - by Michael
    I'm having trouble porting a simple game I developed for the iPhone over to Android. The game has an animated ball which moves from Point A to Point B. The user must touch the ball before it reaches point B or lose the game. This was easy to implement on the iPhone using Core Animation since I could locate the current position of the ball by accessing its animation layer. In Android, I attempted to recreate the game using tweened animation and represented the ball as a Drawable. My issue is that I can't determine if the user is touching the spot because the Drawable apparently bounds do not update as the ball visually moves - making the program think the ball is always in its original position. While searching these forums I saw an Android team dev. confirm that you can't get the current location in a tweened animation but offered no solution for a workaround. Can I accomplish this on the Android using my current approach? If not, what approach should I use? Best regards, Michael

  • What's your release process for your commercial application?

    - by dr. evil
    If you are developing a commercial desktop application, what's your release process? Sample process: Develop it: Patch bugs, add features, etc. Feature Freeze (do not fix, add anything unless it's absolutely required) Test it If everything is OK release it, if it's not fix it, test it, release it I think the most crucial question is what's your approach to "feature freeze test release" cycle? Or do you test it more frequently that you don't need such a cycle and your software is always ready for public release?

  • Question about how to read the Safari/Chrome developer tool result

    - by richard
    Hi, I am using the developer tool in chrome (i think it is the same as safari). I did a timeline when I load wwww.yahoo.com. I attached the screen shot: http://yfrog.com/4jpicture2yyp You see: * Send Request (http://www.yahoo.com) * Receive Response (http://www.yahoo.com) * Receive Response (http://www.yahoo.com) * Event (unload) * Function Call * Recalculate Style * Recalculate Style * Recalculate Style * Parse What I don't understand is why 'Parse' happens AFTER Function call and Recalculate Style? Shouldn't it need to parse HTML source FIRST Before it parses CSS file (I assume which triggers the 'Recalculate Style') and Java Script file (I assume which triggers the 'Function Call')

  • First site going live real soon. Last minute questions

    - by user156814
    I am really close to finishing up on a project that I've been working on. I have done websites before, but never on my own and never a site that involved user generated data. I have been reading up on things that should be considered before you go live and I have some questions. 1) Staging... (Deploying updates without affecting users). I'm not really sure what this would entail, since I'm sure that any type of update would affect users in some way. Does this mean some type of temporary downtime for every update? can somebody please explain this and a solution to this as well. 2) Limits... I'm using the Kohana framework and I'm using the Auth module for logging users in. I was wondering if this already has some type of limit (on login attempts) built in, and if not, what would be the best way to implement this. (save attempts in database, cookie, etc.). If this is not whats meant by limits, can somebody elaborate. 3) Caching... Like I said, this is my first site built around user content. Considering that, should I cache it? 4) Back Ups... How often should I backup my (MySQL) database, and how should I back it up (MySQL export?). The site is currently up, yet not finished, if anybody wants to look at it and see if something pops out to you that should be looked at/fixed. Clashing Thoughts. If there is anything else I overlooked, thats not already in the list linked to above, please let me know. Thanks.

  • How has RIA technology evolved and what technology stack currently rules this domain?

    - by Rachel
    I am new to RIA and have not been actively involved with this technology in my projects as we using server-side Java, but I want to gain some experience with RIA. My questions are: How has RIA technology evolved and in your opinion? What technology stack currently rules this domain? What are the recommended resources for learning RIA? In general what is the suggested approach for getting started on the RIA journey?

  • Continuous Progress Bar in Javascript

    - by Goro
    Hello, I am trying to find the best option to create a simple progress bar that I need to be triggered periodically from within another JavaScript script. Every few minutes, a timer would cause the progress bar to start going from 0 to 100%. Once it reaches 100%, the bar would reset to 0. I am trying to implement a smooth animated version of the bar, like this one: http://www.webappers.com/progressBar/. (I tried adapting this particular one but I could not get it to work the way I described) I am looking into the jQuery UI ProgressBar: Is it possible to use it in the manner I have described? Thank you.

  • Pros and Cons on where to place business logic: app level or DB

    - by Juri
    Hi, I always again encounter discussions about where to place the business logic: inside a business layer in the application code or down in the DB in terms of stored procedures. Personally I'd tend to the 1st approach, but I'd like to hear some opinions from your part first, without influencing you with my personal views. I know there doesn't exist a one-size-fits-all solution and it often depends on many factors, but we can discuss about that. Btw, we are in the context of web applications and our current approach is to have UI layer which accepts UI input and does a first, client-side validation Business layer with a number of service-classes which contains the business logic including validation for user input (server-side) Data Access Layer which calls stored procedures from the DB for doing persistency/read operations Many people however tend to move the business layer stuff (especially regarding the validation) down to the DB in terms of stored procedures. What do you think about it? I'd like to discuss.

  • Populating fields, input types etc using JSON

    - by Franco
    I have a form that works as follows.. Server request builds XML of the data on server side and sends xml, XSL stylesheet then transforms the XML data into the plain html page distributing the data to the relevant/desired locations of the form on the page. Person can view page and edit the populated form, submit back to DB. I think JSON is more suitable for this from what I have read. The form itself is split into 3 areas, for me this is 3 maps/associative arrays etc each with a name related to the id of an input element etc. The problem for me comes with having the JSON sent to the page, what should I do with it next in order to achieve the same result as I currently get with XML and XSL. Thanks.

  • Python: Traffic-Simulation (cars on a road)

    - by kame
    Hello! I want to create a traffic simulator like here: http://www.doobybrain.com/wp-content/uploads/2008/03/traffic-simulation.gif But I didn't thougt very deep about this. I would create the class car. Every car has his own color, position and so on. And I could create the road with an array. But how to tell the car where to go? Could I hear your ideas? EDIT: Is it forbidden to get new ideas from good programmers? Why do some people want to close this thread? Or were to ask such questions? I dont understand them. :(

  • Having an online highscore leaderboard for a Flash game

    - by Marco Fox
    Why, hello there. I'm trying to develop a simple Flash game using Actionscript 2 (I know its a bit dated, but its a simple project that doesen't benefict much from AS3), and I came up with an ideia of implementing an online leaderboard that records and shows the highscore of the player. This isn't anything too complicated, but I seem to be having problem finding resources online that explain how I should implement this. All I want is a call, probably to a PHP/MySQL database that records the player's name (which will be recorded via a input window) and its current score. It would also have to show the best all time scores, by order. I should remind you that I am working on a Actionscript 2 so Actionscript 3 solutions are probably not going to work. Can anyone out there help me out here? Did any of you already been through this?

  • How to communicate between frames?

    - by bangoker
    I'm maintaining an application that goes sort of like this: There is a Page A with a Frame that shows Page B. Now page B is part of a completely different product, so there's a frame in a that just calls B. Now, they want that when B an option in B is clicked, the WHOLE page is redirected to another page in A. The problem is that the url of A is something like "www.client.MyCompany/Order/Details/123" But B doesnt know nothing about A, or which order # it is or anything, but Page A who has the frame B does know it. For know my solution is to just redirect to all the order so something like client.MyCompany/Orders but since B doesn't know which client it is, I'll add it in the webconfig. (so each client has its own webconfig with a different value). I dont find this solution optimal but I can't think of anything else! I already tried putting the needed url in page A in a hidden Div (since A does know all the info) and then trying to read the whole DOM of the page from B to find it.... unfortunately I can only get access to Frame B's DOM... (I tried with jquery). I know frames are evil, but this is how it is written... any ideas? Thanks!

  • How does this Singleton-like web class persists session data, even though session is not updated in

    - by Micah Burnett
    Ok, I've got this singleton-like web class which uses session to maintain state. I initially thought I was going to have to manipulate the session variables on each "set" so that the new values were updated in the session. However I tried using it as-is, and somehow, it remembers state. For example, if run this code on one page: UserContext.Current.User.FirstName = "Micah"; And run this code in a different browser tab, FirstName is displayed correctly: Response.Write(UserContext.Current.User.FirstName); Can someone tell me (prove) how this data is getting persisted in the session? Here is the class: using System; using System.Collections.Generic; using System.Linq; using System.Web; public class UserContext { private UserContext() { } public static UserContext Current { get { if (System.Web.HttpContext.Current.Session["UserContext"] == null) { UserContext uc = new UserContext(); uc.User = new User(); System.Web.HttpContext.Current.Session["UserContext"] = uc; } return (UserContext)System.Web.HttpContext.Current.Session["UserContext"]; } } private string HospitalField; public string Hospital { get { return HospitalField; } set { HospitalField = value; ContractField = null; ModelType = null; } } private string ContractField; public string Contract { get { return ContractField; } set { ContractField = value; ModelType = string.Empty; } } private string ModelTypeField; public string ModelType { get { return ModelTypeField; } set { ModelTypeField = value; } } private User UserField; public User User { get { return UserField; } set { UserField = value; } } public void DoSomething() { } } public class User { public int UserId { get; set; } public string FirstName { get; set; } } I added this to a watch, and can see that the session variable is definitely being set somewhere: (UserContext)System.Web.HttpContext.Current.Session["UserContext"]; As soon as a setter is called the Session var is immediately updated: set { HospitalField = value; //<--- here ContractField = null; ModelType = null; }
