  • Java graphic objects as in flashgames

    - by Ryu Kajiya
    How is it possible (with the standard Java2D engine) to use small sprites like graphic objects? For those who don't know what I mean, in all those Flash-games like on Facebook they put small sprites on the screen which react to mouse-over and clicks. I tried to do the same in Java but can't find a good method. Swing components always spread over the whole bitmap, but I only want to get a reaction from the object when the mouse is over a pixel that's not transparent. So basically checking every time if the object below the mouse contains a non-transparent pixel (which i believe could be pretty intense in a gameloop or repaint loop). I have no idea how to implement such a thing efficiently.

  • Flashing screen hovering over menubar on left side

    - by iwekb
    Just installed Ubuntu 10.10 netbook version on an older Dell Laptop (no other operating system installed). When hovering with mouse over menu bar, the full screen changes to default coloured back ground shortly and then back to normal (as after start-up) again. And that each time the mouse is over any of the (default) icons on the menu bar. I am not able to select any icon. No left or right click works on icons or anywhere on the menubar apart from the left top small icon, white Ubuntu logo, and the right top small icons for WiFi, sound, mail, shut-down etc. Those icons work. I tried re-installation again and all patches are downloaded. Same problem. Problem is that I can't enter commands either to reduce e.g. the swappiness (if that would be of any help). Can somebody help me that encountered similar problem or knows a resolution?

  • How can I make a character move forward in a certain direction?

    - by Shaun Wild
    I have an entity class which is updated every game tick. Let's just assume said entity moves forward constantly. What i want to know is, how can i make it so that i can give an angle to a function and it will make my entity move in that direction. let's say for example moveForward(90); Would make my character move to the right, or for example declaring my rotation as a global Integer: moveForward(rotation); rotation++; Would make my entity move around in a small circle, I assume this includes some kind of vector math, which I haven't done any studying on so a brief explanation of that if it's necessary would be nice. I would appreciate a small code snippet and an explanation I can analyze, thanks in advanced :)

  • How can I design multi-threaded application for larger user base

    - by rokonoid
    Here's my scenario, I need to develop a scalable application. My user base may be over 100K, every user has 10 or more small tasks. Tasks check every minute with a third party application through web services, retrieving data which is written in the database, then the data is forwarded to it's original destination. So here's the processing of a small task: while(true){ Boolean isNewInformationAvailable = checkWhetherInformationIsAvailableOrNot(); If(isNewInformationAvailable ==true){ fetchTheData(); writeToDatabase(); findTheDestination(); deliverTheData(); isAvailable =false; } } As the application is large, how should I approach designing this? I'm going to use Java to write it. Should I use concurrency, and how would you manage the concurrency?

  • Has anyone used Genetify for A/B testing

    - by Joshak
    I'm working on a small project that will likely run on Wordpress, I always like to run some split testing to improve conversion rates for various goals. Typically if its a small site that I either don't have a budget for or want to keep it as inexpensive as possible I use Google Website Optimizer if I do have a budget I go with Visual Website Optimizer both are great and affordable, but for fun I was checking out alternatives and found Genetify which is an open source project and has some neat features. In searching around I don't see many people talking about it and wondered if anyone here has used it. If so what do you think about it?

  • Hosting rails sites; vps or shared, and how much ram? [closed]

    - by raphael_turtle
    Possible Duplicate: How to find web hosting that meets my requirements? I have 3 rails sites to launch, all of which are fairly small and consisting of a custom cms, one with an online store, and 2 sinatra sites which are mainly static, portfolio sites. What would be the best way to host these sites (I've deployed on dreamhost shared before and some vps's) Is it best to manage them together under one vps? e.g linode $20/m (for the cheapest option, 512mb and would that even be enough ram?) or keep each rails site separate and host each one on a small vps? e.g $4/m (there's often lots of deals like this on webhostingtalk) I'm currently hosting the sinatra sites for free on heroku but finding it a bit slow sometimes.

  • Cost vs. Fun - Dilemma about learning a serverside language [closed]

    - by Ixx
    I want to learn a new server-side language. I already know Java. I'm fascinated by Scala, have read about it a lot, and want to get practical experience. But I also have some concerns of practical nature - I want to do the backend for many small, non-profit apps, and pay the lowest price for hosting possible. I also want that other people can easily contribute to these apps, if applicable. This leads me in PHP's direction. But I don't like PHP and would like to use these small projects to learn Scala instead. You see the problem, I don't want to pay more money each month, from my own pocket, for hosting. But I want to use these projects to learn Scala. Is there a practical solution for this?

  • php cms withouth database

    - by user1791795
    A friend of mine asked me for a easy website for him. As it was just 3 subpages, no database need or anything, I've done it quite fast with plain PHP, HTML, JS and CSS. But then another and another friend showed up. They only wanted arrange differently they navigation, some different picutures etc. So I though, is there any kind of CMS, that allows build small business website (barbershop, local groceries shop), with small list of subpages, yet allowing us to arrange look'n'feel. There's no need for the databas as content won't change, or can be stored in simple textfiles for example. Things like WordPress might be simple overkill Does anyone know such cms?
