  • XNA - 2D Tile Lighting

    - by Cyral
    Im adding lighting to my 2D Tile based game. I found the link http://blog.josack.com/2011/07/xna-2d-dynamic-lighting.html useful, but the way its done it dosent support collision. What Id like is some help or links as I want one that can have -always lit up light points -collision (If the light ray hits a block, then dim the next block by whatever amount until its dark) Im a noob at this stuff, but ive been searching around for quite a while but no luck (I did find Catalin's tutorial, but it seemed abit advanced for me)

  • Strict doctype - form and input element

    - by David
    Does anyone know the reasoning behind the strict doctype not allowing input elements to be direct descendents of a form element. I find it annoying that i have to wrap a submit button which is a block level element inside another block level element say a fieldset or a div. However, I cannot find an answer anywhere as to why this actually is.

  • gcc segmentation fault compiling 20k file

    - by aaa
    hi. I have fairly large file, 20k lines long (auto generated). It has been compiling okay, but after adding new if/endif preprocessor block, I started getting gcc internal errors: segmentation fault. the code inside new preprocessor block is not being compiled, so I am not sure where the error is coming from. my only guess is memory, but as far as I can tell it does not exhaust computer memory. Any thoughts?

  • Send/cache multidimensional array to php with jQuery

    - by robertdd
    hy, i have a little, big problem here :) after i upload some images i get a list with all the images. I have some jQuery function for rotate, duplicate, delete, shuffle images! when i select a image and hit delete i send a post to php with the alt="" value of the image,i identify the picture and edit. I want to make a save button, Instead of sending a post every time i rotate a image, better send a post after editing the list of images with an array that contains all data? my php array after upload looks like this: [files] => Array ( [lcxkijgr] => lcxkijgr.jpg [xcewxpfv] => xcewxpfv.jpg [rtiurwxf] => rtiurwxf.jpg [gsbxdsdc] => gsbxdsdc.jpg ) say that I uploaded 4 pictures, firs picture i rotate 90 degrees second i want to duplicate third i rotate 270 degrees and the fourth image i delete i can do all this only with jQuery, but on the server the images are the same, after a refresh the images are the same this is the list with the images: <div class="upimage"> <ul id="upimagesQueue"> <li id="upimagesHPVEJM"> <a href="javascript:jQuery('#upimagesHPVEJM').showlargeimage('HPVEJM')"> <img alt="lcxkijgr" src="uploads/s6id9r9icnp8q9102h8md9kfd7/lcxkijgr.jpg?1272087830477" id="HPVEJM" style="display: block;" > </a> </li> <li id="upimagesSTCSAV"> <a href="javascript:jQuery('#upimagesSTCSAV').showlargeimage('STCSAV')"> <img alt="xcewxpfv" src="uploads/s6id9r9icnp8q9102h8md9kfd7/xcewxpfv.jpg?1272087831360" id="STCSAV" style="display: block;" > </a> </li> <li id="upimagesBFPUEQ"> <a href="javascript:jQuery('#upimagesBFPUEQ').showlargeimage('BFPUEQ')"> <img alt="rtiurwxf" src="uploads/s6id9r9icnp8q9102h8md9kfd7/rtiurwxf.jpg?1272087832162" id="BFPUEQ" style="display: block;" > </a> </li> <li id="upimagesRKXNSV"> <a href="javascript:jQuery('#upimagesRKXNSV').showlargeimage('RKXNSV')"> <img alt="gsbxdsdc" src="uploads/s6id9r9icnp8q9102h8md9kfd7/gsbxdsdc.jpg?1272087832957" id="RKXNSV" style="display: block;"> </a> </li> <ul> </div> is ok if i make one array like this: array{ imgFromLi = array(img1,img2,img3,img4,img5,img6) rotate = array{img1=90, img2=270, img3=90} delete = array{img4,img5,img6} duplicate = array{img2, img3} } how i can send/cache this array?? sorry for my very bad english

  • Finding leaks under GeneralBlock-16?

    - by erastusnjuki
    If ObjectAlloc cannot deduce type information for the block, it uses 'GeneralBlock'. Any strategies to get leaks from this block that may eliminate the need of my 'trial and error' methods that I use? The Extended Detail thing doesn't really do it for me as I just keep guessing.

  • How do I use the information about exceptions a method throws in .NET in my code?

    - by dotnetdev
    For many methods in .NET, the exceptions they can potentially throw can be as many as 7-8 (one or two methods in XmlDocument, Load() being one I think, can throw this many exceptions). Does this mean I have to write 8 catch blocks to catch all of these exceptions (it is best practise to catch an exception with a specific exception block and not just a general catch block of type Exception). How do I use this information? Thanks

  • Designing a database file format

    - by RoliSoft
    I would like to design my own database engine for educational purposes, for the time being. Designing a binary file format is not hard nor the question, I've done it in the past, but while designing a database file format, I have come across a very important question: How to handle the deletion of an item? So far, I've thought of the following two options: Each item will have a "deleted" bit which is set to 1 upon deletion. Pro: relatively fast. Con: potentially sensitive data will remain in the file. 0x00 out the whole item upon deletion. Pro: potentially sensitive data will be removed from the file. Con: relatively slow. Recreating the whole database. Pro: no empty blocks which makes the follow-up question void. Con: it's a really good idea to overwrite the whole 4 GB database file because a user corrected a typo. I will sell this method to Twitter ASAP! Now let's say you already have a few empty blocks in your database (deleted items). The follow-up question is how to handle the insertion of a new item? Append the item to the end of the file. Pro: fastest possible. Con: file will get huge because of all the empty blocks that remain because deleted items aren't actually deleted. Search for an empty block exactly the size of the one you're inserting. Pro: may get rid of some blocks. Con: you may end up scanning the whole file at each insert only to find out it's very unlikely to come across a perfectly fitting empty block. Find the first empty block which is equal or larger than the item you're inserting. Pro: you probably won't end up scanning the whole file, as you will find an empty block somewhere mid-way; this will keep the file size relatively low. Con: there will still be lots of leftover 0x00 bytes at the end of items which were inserted into bigger empty blocks than they are. Rigth now, I think the first deletion method and the last insertion method are probably the "best" mix, but they would still have their own small issues. Alternatively, the first insertion method and scheduled full database recreation. (Probably not a good idea when working with really large databases. Also, each small update in that method will clone the whole item to the end of the file, thus accelerating file growth at a potentially insane rate.) Unless there is a way of deleting/inserting blocks from/to the middle of the file in a file-system approved way, what's the best way to do this? More importantly, how do databases currently used in production usually handle this?

  • Good style for handling constructor failure of critical object

    - by mtlphil
    I'm trying to decide between two ways of instantiating an object & handling any constructor exceptions for an object that is critical to my program, i.e. if construction fails the program can't continue. I have a class SimpleMIDIOut that wraps basic Win32 MIDI functions. It will open a MIDI device in the constructor and close it in the destructor. It will throw an exception inherited from std::exception in the constructor if the MIDI device cannot be opened. Which of the following ways of catching constructor exceptions for this object would be more in line with C++ best practices Method 1 - Stack allocated object, only in scope inside try block #include <iostream> #include "simplemidiout.h" int main() { try { SimpleMIDIOut myOut; //constructor will throw if MIDI device cannot be opened myOut.PlayNote(60,100); //..... //myOut goes out of scope outside this block //so basically the whole program has to be inside //this block. //On the plus side, it's on the stack so //destructor that handles object cleanup //is called automatically, more inline with RAII idiom? } catch(const std::exception& e) { std::cout << e.what() << std::endl; std::cin.ignore(); return 1; } std::cin.ignore(); return 0; } Method 2 - Pointer to object, heap allocated, nicer structured code? #include <iostream> #include "simplemidiout.h" int main() { SimpleMIDIOut *myOut; try { myOut = new SimpleMIDIOut(); } catch(const std::exception& e) { std::cout << e.what() << std::endl; delete myOut; return 1; } myOut->PlayNote(60,100); std::cin.ignore(); delete myOut; return 0; } I like the look of the code in Method 2 better, don't have to jam my whole program into a try block, but Method 1 creates the object on the stack so C++ manages the object's life time, which is more in tune with RAII philosophy isn't it? I'm still a novice at this so any feedback on the above is much appreciated. If there's an even better way to check for/handle constructor failure in a siatuation like this please let me know.

  • Is this ruby code thread safe?

    - by Ben K.
    Is this code threadsafe? It seems like it should be, because @myvar will never be assigned from multiple threads (assuming block completes in < 1s). But do I need to be worried about a situation where the second block is trying to read @myvar as it's being written? require 'rubygems' require 'eventmachine' @myvar = Time.now.to_i EventMachine.run do EventMachine.add_periodic_timer(1) do EventMachine.defer do @myvar = Time.now.to_i # some calculation and reassign end end EventMachine.add_periodic_timer(0.5) do puts @myvar end end

  • Custom Items in Lists in C# forms?

    - by chaz
    I'm a bit new to the C#-form app developing and I want know, what's the best way around at making a control that holds a list of horizontal items. In which each of these items are horizontally ruled to it's parent control, contain a thumbnail to the left and a large text block to the right of image and a smaller text block underneath that. So basically this isn't a predefined control I can find in the toolbox. Any ideas?

  • jQuery toggling divs, expand collapse all and keep first item selected when page loads

    - by hollyb
    Hi, I have a question about some functionality I'm trying to add to my jQuery to enable a button or text to expand/contract all the divs on click... and I'd like to figure out how to keep the first div open when the page loads. Here is the jQuery: (document).ready(function(){ //Hides containers on load $(".toggle_container").hide(); //Switch "Open" and "Close" state on click $("h2.trigger").toggle(function(){ $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); //Slide up and down on click $("h2.trigger").click(function(){ $(this).next(".toggle_container").slideToggle("slow"); }); }); And the css: // uses a background image with an on (+) and off (-) state stacked on top of each other h2.trigger { background: url(buttonBG.gif) no-repeat;height: 46px;line-height: 46px;width: 300px;font-size: 2em;font-weight: normal;} h2.trigger a {color: #fff;text-decoration: none; display: block;} h2.active {background-position: left bottom;} .toggle_container { overflow: hidden; } .toggle_container .block {padding: 20px;} And the html <h2 class="trigger"><a href="#">Heading</a></h2> <div class="toggle_container"> <div class="block">Stuff goes here</div> </div> <h2 class="trigger"><a href="#">Heading 2</a></h2> <div class="toggle_container"> <div class="block">Stuff goes here</div> </div> So it works great and looks great. However, when I try to get it to keep the first instance open, the background image that should adjust show the (-) state doesn't change. The code I used to this was: $(".toggle_container:first").show(); So, my question is, does anyone know of an easier way to show the first instance of this as open without having to created specials rules/class for the first item? Also, any ideas about how to make an open all/close all link? Thanks!

  • how to make Xcode indentation from beginning of previous line?

    ok, possibly insanely n00b question or something i have overlooked in Xcode prefs: On pressing return, in stead of Xcode's syntax-aware indentation doing smart indent from whatever brackets i've used on the previous line, how can I make it so Xcode indents just from the beginning of the previous line? From the picture below, first block of code is what i got, second block of code is what I want. Visual representation:

  • Table clusters in SQLServer

    - by Bruno Martinez
    In Oracle, a table cluster is a group of tables that share common columns and store related data in the same blocks. When tables are clustered, a single data block can contain rows from multiple tables. For example, a block can store rows from both the employees and departments tables rather than from only a single table: http://download.oracle.com/docs/cd/E11882_01/server.112/e10713/tablecls.htm#i25478 Can this be done in SQLServer?

  • Hide blocks on page not found in Drupal

    - by Tommy
    I have google adsense in a block, and I want to hide the block when the page is a "Page not found" error page. It's against adsenses TOS to show their ads on error pages. I figure there must be a way to write a php script to put in the Page specific visibility options. Does anyone know how to do this?
