  • Hide collision layer in libgdx with TiledMap?

    - by Daniel Jonsson
    I'm making a 2D game with libgdx, and I'm using its TileMapRenderer to render my map which I have made in the map editor Tiled. In Tiled I have a dedicated collision layer. However, I can't figure out how I'm supposed to hide it and its tiles in the game. This is how a map is loaded: TiledMap map = TiledLoader.createMap(Gdx.files.internal("maps/map.tmx")); TileAtlas atlas = new TileAtlas(map, Gdx.files.internal("maps")); tileMapRenderer = new TileMapRenderer(map, atlas, 32, 32); Currently the collision tiles are rendered on top of everything else, as I see them in the map editor.

  • Master database Compatibility level after an In-place Upgrade

    - by Jonathan Kehayias
    Yesterday a forums member asked why sys.dm_exec_sql_text() wouldn’t work on one instance of SQL where he was a sysadmin while the same code worked correctly on another instance of SQL.  The initial thought was that it was some kind of permissions issue.  Ken Simmons ( blog / twitter ) pointed out that the compatibility level of the database would affect the ability to use this DMF and that running it from a database at 80 compatibility would fail.  It turns out the person was running...(read more)

  • Where do I place XNA content pipeline references?

    - by Zabby Wabby
    I am relatively new to XNA, and have started to delve into the use of the content pipeline. I have already figured out that tricky issue of adding a game library containing classes for any type of .xml file I want to read. Here's the issue. I am trying to handle the reading of all XML content through use of an XMLHandler object that uses the intermediate deserializer. Any time reading of such data is required, the appropriate method within this object would be called. So, as a simple example, something like this would occur when a character levels: public Spell LevelUp(int levelAchived) { XMLHandler.FindSkillsForLevel(levelAchived); } This method would then read the proper .xml file, sending back the spell for the character to learn. However, the XMLHandler is having issues even being created. I cannot get it to use the using namespace of Microsoft.Xna.Framework.Content.Pipeline. I get an error on my using statement in the XMLHandler class: using Microsoft.Xna.Framework.Content.Pipeline.Serialization.Intermediate; The error is a typical reference error: Type or namespace name "'Pipeline' does not exist in the namespace 'Microsoft.Xna.Framework.Content' (are you missing an assembly reference?)" I THINK this is because this namespace is already referenced in my game's content. I would really have no issue placing this object within my game's content (since that is ALL it deals with anyways), but the Content project does not seem capable of holding anything but content files. In summary, I need to use the Intermediate Deserializer in my main project's logic, but, as far as I can make out, I can't safely reference the associated namespace for it outside of the game's content. I'm not a terribly well-versed programmer, so I may be just missing some big detail I've never learned here. How can I make this object accessible for all projects within the solution? I will gladly post more information if needed!

  • Optical Illusion Freezes Water In Place [Video]

    - by Jason Fitzpatrick
    This clever optical illusion uses sound frequency and a digital camera to “freeze” water in time and space. YouTube user MrBibio explains the hack: Creating the illusion of a static flow of water using sound. Of course this isn’t my idea and plenty more refined examples already exist. I tried this same experiment years ago but using a strobe light, but it’s harsh on the eyes after a while and hard to video successfully. It only dawned on me shortly before making this that for video purposes, no strobe light is required. This is because the frame rate and shutter of the camera is doing a similar job to the strobe. The speaker-as-frequency-generator model is definitely easier on the eyes than similar experiments that rely on high-speed strobes.

  • Starcraft 2 - Third Person Custom Map

    - by Norla
    I would like to try my hand at creating a custom map in Starcraft 2 that has a third-person camera follow an individual unit. There are a few custom maps that exist with this feature already, so I do know this is possible. What I'm having trouble wrapping my head around are the features that are new to the SC2 map editor that didn't exist in the Warcraft 3 editor. For instance, to do a third-person map, do I need a custom mods file, or can everything be done in the map file? Regardless, is it worth using a mod file? What map settings do I NEED to edit/implement? Which are not necessary, but recommended?

  • Where is a good place to start to learn about custom caching in .Net

    - by John
    I'm looking to make some performance enhancements to our site, but I'm not sure exactly where to begin. We have some custom object caching, but I think that we can do better. Our Business We aggregate news stories on a news type of web site. We get approximately 500-1000 new stories per week. We have index pages that show various lists of the items and details pages that show the individual stories. Our Current Use case: Getting an Individual Story User makes a request The Data Access Layer(DAL) checks to see if the item is in cache and if item is fresh (15 minutes). If the item is not in cache or is not fresh, retrieve the item from SQL Server, save to cache and return to user. Problems with this approach The pull nature of caching means that users have to pay the waiting cost every time that the cache is refreshed. Once a story is published, it changes infrequently and I think that we should replace the pull model with something better. My initial thoughts My initial thought is that stories should ALL be stored locally in some type of dictionary. (Cache or is there another, better way?). If the story is not found, then make a trip to the database, update the local dictionary and send the item back. Since there may be occasional updates to stories, this should be an entirely process from the user. I watched a video by Brent Ozar, How StackOverflow Scales SQL Server, in which Brent states "the fastest database query is the one that you don't make". Where do I start? At this point, I don't know exactly what the solution is. Is it caching? Is there a better way of using local storage? Do I use a Dictionary, OrderedDictionary, List ? It seems daunting and I'm just looking for some good starting points to learn more about how to do this type of optimization.

  • How to use GCC 4.7 in place of 4.6 (Ubuntu 12.04)

    - by Larz Conwell
    So I'm working on a project and I wanted to use some C11 features for C. To use those features GCC 4.7 is required, so I went to synaptic and looked up 4.7, and I found the packages gcc-4.7-base so I installed it[1]. So now that gcc-4.7-base is installed I expected to be able to use 4.7, but no, when I do gcc --version it still shows 4.6.3 even more, when I try to directly call 4.7(via /usr/bin/gcc-4.7) it doesn't exist, though a gcc-4.6 executable does exist. How do I "activate" GCC 4.7? I read here, you do some crazy stuff with update-alternatives, but it doesn't work for me as the gcc-4.7 executable doesn't actually exist on my machine. Notes: 1. I also saw gcc-4.6-base, so I figured I'd uninstall it, but synaptic attempted to remove every package I had installed and install a Java runtime, so for obvious reason I decided not to remove it.

  • Braces (syntax) highlighting in OpenOffice Math formula text editor

    - by Oleksandr Bolotov
    When you use OpenOffice Math, in upper part you see formula and formula text editor in lower part. Almost like this: %sigma = 2 %mu %epsilon + %lambda Tr(%epsilon)I So my questions are: How to replace OpenOffice Math's formula text editor with own text editor? ... or how to enable braces (syntax) highlighting in embedded editor? ... are there any extensions for anything like this? I need this because sometimes it's too much braces and stuff and it's hard to distinguish which braces match each other. Please do not suggest me to use MathType Mathematica (or anything) instead of OpenOffice Math (because I'm almost happy with it:)

  • What is the best way to implement paginated text editing in Python?

    - by W.F
    I'm trying to build a formatted text editor in python. I need the editor to be paginated on edit mode. Same as in all popular word processors - when the user is editing the document what he/she sees is a representation of the actual, physical, page. I've tried looking into PySide but I can't find any ready solution to this, nor I can work out a way to do it myself. I am totally open to new technologies, so if you think Python is not the right choice here I would love to hear about new stuff (especially when I'm this new to UI coding). It only needs to be cross-platform and let me do rapid development (hence me looking for an out-of-the-box solution to this). Please suggest the best way to implement this. Please also note that I am looking for either a ready solution or an advice on how to tackle this. Thank you very much !

  • What's the best language to use for a simple windows 7 dynamic gui desktop app [closed]

    - by Gregor Samsa
    [Note: I hope I am not breaking etiquette, but I originally posted a variant on this question here, but am re-asking here because I am making this now solely a question about programming.] I would like to program of the following simple form: The user can produce X number of resizable frames (analogous to HTML frames). Each frame serves as a simple text editor, which you can type into and save the whole configuration including resized windows and text. The user should be able alternately "freeze" and present the information, and "unfreeze" and edit frames. Thus it will be a cross between a calendar and a text editor. I don't particularly care if it is a web application or not. What languages are ideal for such a setup? I know some C and Python and Html, and am willing to learn others if need be. It seems to me this should be a relatively easy program to make, but I need a little direction before starting. EDIT: My OS is Windows 7.

  • Photos being copied all over the place

    - by plua
    We have a rather popular website with plenty of photos. Our whole business depends on our content - and the photos are important in this. We invest a lot of time, effort, and money into taking these pictures. On our website we have clear copyright notices, we have the website name and logo in the photos, and we have a Photo Licensing page which states the prices of licensing our photos. Despite all this, our photos are copied by personal and commercial websites alike. We really want to do something about this. We do not want them to take out the photos and leave it at that. We want them to pay for the usage, as we clearly state on our website. Now a few questions come to mind: Can we legally force them to pay right away? Or are we obligated to first write a "Cease and Desist" letter? Photos are used on websites throughout the world. Are there any worldwide rules for this? Has anybody experience with doing these things outside of their home country? Should we hire a lawyer in any country? Or could a local lawyer contact oversees companies directly?

  • Where to place php libraries/extensions?

    - by gdaniel
    I am new to a lot of server configurations and options. I want to add extra php libraries/extensions to my server. Where do I add them? (I am on a CENTOS 6.5 VPS) For example, I want to add the phpseclib php extension: Their website instructions are minimum: Usage This library is written using the same conventions that libraries in the PHP Extension and Application Repository (PEAR) used to be written in (current requirements break PHP4 compatibility). In particular, this library needs to be in your include_path: <?php set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib'); include('Net/SSH2.php'); ?> It tells me how to use it, but it doesn't tell me where to add the actual extension files. Should I added it under? usr/local/lib ? usr/local/lib/php ? usr/local/lib/php/pear ? Or can I add it under public_html? Also, my VPS has several users under /home/.. is that away to make the library available for only one user?

  • how to calculate intersection time and place of multiple moving arcs

    - by user20733
    I have rocks orbiting moons, moons orbiting planets, planets orbiting suns, and suns orbiting black holes, and the current system could have many many layers of orbitage. the position of any object is a function of time and relative to the object it orbits. (so far so good). now I want to know for a given 2 objects(A,B), a start time and a speed, how can I work out the when and where to go. I can work out where A and B is given a time. so i just need. 1: direction to travel in from A to B(remember B is moving(not in a straight line)) 2: Time to get to b in a straight line. travel must be in a straight line with the shortest possible distance. as an extension to this question, how will i know if its better to wait, EG is it faster to stay on object A and wait for a hour when the objects may be closer, than to set off from A to B at the start. Cheers, it hurt my brain.

  • Menus don't sync in the first place

    - by Bruce Mincks
    I have been wrestling with prompts about my default key ring for months, finally made contact with Ubuntu with the right password, and find that when I try to sync evolution Ubuntu directs me to "system-preferences- " and then the road forks between the "passwords and encryption" you indicate and the "encryption and keyrings. I have no idea which version I am using, at this point. The road goes downhill from there. I would really like to synch my windows manager and Inkscape vs. ImageMagick display (circles display as semicircles). Can someone set me straight?

  • Are there new flexible texteditors? [closed]

    - by RParadox
    Vi(m) and Emacs are almost 40 years old. Why are they still the standard, and what attempts have been made at coming up with a new flexible editor? Are there any features which can not be built into vim/emacs? My question is similar to this one: Time to drop Emacs and vi? No one had a suggestion, which surprises me. I would have thought that the core of a texteditor is very small and that people brew their own. Perhaps nobody wants to deal with supporting all the modes? Edit to clarify my question: Instead of writing modes and scripts I ask myself, why there is not a much lightweight project, which lets people custom the editor more directly? Vim has 365395 LOC (C lines all included), Emacs 1.5 million LOC. Why is there a project with say 50k LOC, which is the core, why people can use more freely? Perhaps there is such project, I haven't looked very far. I thought about putting together modules from Vim myself and experimenting with some ideas. The core of editing shouldn't be more than 10k? Vim has a lot optimizations which is really an overkill nowadays. Basically I'm looking for a code base for my own editor and Vi/Emacs are I believe not intended to be used in this way. Bill Joy said the following about vi. http://web.cecs.pdx.edu/~kirkenda/joy84.html The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands. In some sense, its backwards from the kind of thing you'd get from a mouse-oriented thing. I think multiple levels of undo would be wonderful, too. But fundamentally, vi is still ed inside. You can't really fool it. Its like one of those pinatas - things that have candy inside but has layer after layer of paper mache on top. It doesn't really have a unified concept. I think if I were going to go back - I wouldn't go back, but start over again.

  • VS2010 Text Editor: How do I set the default formatting style for inline code blocks?

    - by nukefusion
    I've got a problem with the formatting of inline code blocks within the VS2010 text editor and wonder if anyone else has had similar problems and found the 'magic' setting I'm looking for. I'm working my way through tutorials in an MVC book. Whenever I add some inline code blocks to a view I want them formatted like so: <% foreach (var link in Model) { %> <a href="<%=Url.RouteUrl(link.RouteValues)%>"> <%=link.Text%> </a> <% } %> What I'm actually getting is this (auto-formatted by the IDE when I finish writing the code): <% foreach (var link in Model) { %> <a href="<%=Url.RouteUrl(link.RouteValues)%>"> <%=link.Text%> </a> <% } %> It's pretty irritating. Any ideas on how I can instruct the IDE to leave my <% % tags alone? I've been fiddling with options under "Tools - Options - Text Editor" for ages but alas am getting nowhere...
