• How do I add a Rigid body and a box collider component to a Texture2D?

  - by gamenewdev

  I am making a snake game. I'm basing it on a basic tutorial game, which does no collision detection, wall checking or different levels. All snake head, piece, food, even the background is made of Texture2D. I want the head of the snake to detects 2D collisions with them, but Rect.contains isn't working. I'd prefer to detect collisions by onTriggerEnter() for which I need to add BoxCollider to my snakeHead.

• Doing imagemagick like stuff in Unity (using a mask to edit a texture)

  - by Codejoy

  There is this tutorial in imagemagick http://www.imagemagick.org/Usage/masking/#masks I was wondering if there was some way to mimic the behavior (like cutting the image up based on a black image mask that turns image parts transparent... ) and then trim that image in game... trying to hack around with the webcam feature and reproduce some of the imagemagick opencv stuff in it in Unity but I am saddly unequipped with masks, shaders etc in unity skill/knowledge. Not even sure where to start.

• How to synchronize the ball in a network pong game?

  - by Thaars

  I’m developing a multiplayer network pong game, my first game ever. The current state is, I’ve running the physic engine with the same configurations on the server and the clients. The own paddle movement is predicted and get just confirmed by the authoritative server. Is a difference detected between them, I correct the position at the client by interpolation. The opponent paddle is also interpolated 200ms to 100ms in the past, because the server is broadcasting snapshots every 100ms to each client. So far it works very well, but now I have to simulate the ball and have a problem to understanding the procedure. I’ve read Valve’s (and many other) articles about fast-paced multiplayer several times and understood their approach. Maybe I can compare my ball with their bullets, but their advantage is, the bullets are not visible. When I have to display the ball, and see my paddle in the present, the opponent in the past and the server is somewhere between it, how can I synchronize the ball over all instances and ensure, that it got ever hit by the paddle even if the paddle is fast moving? Currently my ball’s position is simply set by a server update, so it can happen, that the ball bounces back, even if the paddle is some pixel away (because of a delayed server position). Until now I’ve got no synced clock over all instances. I’m sending a client step index with each update to the server. If the server did his job, he sends the snapshot with the last step index of each client back to the clients. Now I’m looking for the stored position at the returned step index and compare them. Do I need a common clock to sync the ball? EDIT: I've tried to sync a common clock for the server and all clients with a timestamp. But I think it's better to use an own stepping instead of a timestamp (so I don't need to calculate with the ping and so on - and the timestamp will never be exact). The physics are running 60 times per second and now I use this for keeping them synchronized. Is that a good way? When the ball gets calculated by each client, the angle after bouncing can differ because of the different position of the paddles (the opponent is 200ms in the past). When the server is sending his ball position, velocity and angle (because he knows the position of each paddle and is authoritative), the ball could be in a very different position because of the different angles after bouncing (because the clients receive the server data after 100ms). How is it possible to interpolate such a huge difference? I posted this question some days ago at stackoverflow, but got no answer yet. Maybe this is the better place for this question.

• SQLBits just got bigger

  If you’ve had your ear to the twitter ground you will have seen that the provisional agenda for SQLBIts has been put online. http:// sqlbits .com/information/agenda.aspx You will also notice that we have put on a little weight.

  I'm using Ubuntu 12.04 in VirtualBox on a MacBook. The current shortcut for the dash home launcher is the Command key (Super). I'm trying to disable it.

• Alternatives to the Singleton Design Pattern

  The Singleton Design Pattern is one of the simplest and most widely known design patterns in use in software development. However, despite its simplicity, it is very easy to get wrong and the consequences of its use even when properly implemented can outweigh its benefits. It turns out there are other ways to achieve the goals of the Singleton pattern which will often prove to be simpler, safer, and more maintainable.

• How to only render part of an image in lwjgl/openGL

  - by Ephyxia

  I'm making a mining/building game in java using slick2D and I want to make it so you can only see a few blocks in any direction while you are underground. The best example I could find of what I want to do is the game miner dig deep. One way I thought of doing it would be to have a large image and just draw transparent areas on it where you need to be able too see but even if that would be an efficient method I wouldn't be sure how to do that.

• How to remove configuration files completely

  - by Jasper Loy

  Recently I uninstalled some software using sudo apt-get --purge autoremove, thinking that this would remove all traces of it including unused dependencies and configuration files. However I discovered that a configuration file was left behind in my home folder. Is there a more powerful command which would remove even that? As a related question about keeping things clean , is is safe to delete the hidden files and folders under home, if they are merely configuration files, or are there other kinds of files?

• Boosting That Return Rate

  I've noticed something about most beginner Internet marketers. They get really excited when they get traffic - even if that traffic doesn't convert to anything in the way of sales or proceeds. They're over the moon about the chance to make a profit. That's where they go wrong, unfortunately. It's fun to be excited at first, but after a week or so, reality really needs to set in and you need to start making decisions based on factors like conversions and ROI rather than raw traffic.

• SSMS Tools Pack 3.0 is out. Full SSMS 2014 support and improved features.

  - by Mladen Prajdic

  With version 3.0 the SSMS 2014 is fully supported. Since this is a new major version you'll eventually need a new license. Please check the EULA to see when. As a thank you for your patience with this release, everyone that bought the SSMS Tools Pack after April 1st, the release date of SQL Server 2014, will receive a free upgrade. You won't have to do anything for this to take effect. First thing you'll notice is that the UI has been completely changed. It's more in line with SSMS and looks less web-like. Also the core has been updated and rewritten in some places to be better suited for future features. Major improvements for this release are: Window Connection Coloring Something a lot of people have asked me over the last 2 years is if there's a way to color the tab of the window itself. I'm very glad to say that now it is. In SSMS 2012 and higher the actual query window tab is also colored at the top border with the same color as the already existing strip making it much easier to see to which server your query window is connected to even when a window is not focused. To make it even better, you can not also specify the desired color based on the database name and not just the server name. This makes is useful for production environments where you need to be careful in which database you run your queries in. Format SQL The format SQL core was rewritten so it'll be easier to improve it in future versions. New improvement is the ability to terminate SQL statements with semicolons. This is available only in SSMS 2012 and up. Execution Plan Analyzer A big request was to implement the Problems and Solutions tooltip as a window that you can copy the text from. This is now available. You can move the window around and copy text from it. It's a small improvement but better stuff will come. SQL History Current Window History has been improved with faster search and now also shows the color of the server/database it was ran against. This is very helpful if you change your connection in the same query window making it clear which server/database you ran query on. The option to Force Save the history has been added. This is a menu item that flushes the execution and tab content history save buffers to disk. SQL Snippets Added an option to generate snippet from selected SQL text on right click menu. Run script on multiple databases Configurable database groups that you can save and reuse were added. You can create groups of preselected databases to choose from for each server. This makes repetitive tasks much easier New small team licensing option A lot of requests came in for 1 computer, Unlimited VMs option so now it's here. Hope it serves you well.

• Wink and Grow Rich Online, a SEO Perspective

  There are thousands of online businesses making money, and even fewer online businesses creating wealth. The "difference" could be the reason why wealth seems to elude you no matter how hard you are working on making money. The irony is that if you are running after money, you may make some, and lose some. However, if you are focused on creating wealth, you will find that money will find its way to you, and what you build will keep growing in "value" with each passing day.
