• In a 2D tile-based game, how should NPCs and tiles reference each other?

  - by lezebulon

  I'm making a tile engine for 2D games (seen from the top). Basically the world is composed of a grid of tiles. Now I want to put for instance NPCs that can move on the map. What do you think is best: 1) each tile has a pointer to the NPC that is on its tile, or a NULL pointer 2) having a list of NPCs, and they have the coordinates of the tile they are on. 3) something else? 1) is faster for collision detection but it would use much more memory space and it is slower to find all NPCs in a map. 2) is the opposite. thanks

• How to avoid oscillation by async event based systems?

  - by inf3rno

  Imagine a system where there are data sources which need to be kept in sync. A simple example is model - view data binding by MVC. Now I intend to describe these kind of systems with data sources and hubs. Data sources are publishing and subscribing for events and hubs are relaying events to data sources. By handling an event a data source will change it state described in the event. By publishing an event the data source puts its current state to the event, so other data sources can use that information to change their state accordingly. The only problem with this system, that events can be reflected from the hub or from the other data sources, and that can put the system into an infinite oscillation (by async or infinite loop by sync). For example A -- data source B -- data source H -- hub A -> H -> A -- reflection from the hub A -> H -> B -> H -> A -- reflection from another data source By sync it is relatively easy to solve this issue. You can compare the current state with the event, and if they are equal, you don't change the state and raise the same event again. By async I could not find a solution yet. The state comparison does not work by async event handling because there is eventual consistency, and new events can be published in an inconsistent state causing the same oscillation. For example: A(*->x) -> H -> B(y->x) -- can go parallel with B(*->y) -> H -> A(x->y) -- so first A changes to x state while B changes to y state -- then B changes to x state while A changes to y state -- and so on for eternity... What do you think is there an algorithm to solve this problem? If there is a solution, is it possible to extend it to prevent oscillation caused by multiple hubs, multiple different events, etc... ? update: I don't think I can make this work without a lot of effort. I think this problem is just the same as we have by syncing multiple databases in a distributed system. So I think what I really need is constraints if I want to prevent this problem in an automatic way. What constraints do you suggest?

  i would like to add a mysql query somewhere in my timer code so that everytime it restarts then 1 item would be added to the database, i can get it to show how many items you have gotten since the timer has been running, but im not quite sure how to add it into a mysql database, any help would be appreciated :D heres my timer code thus far: <head> <script type="text/javascript"> var c=10; var mineCount = 0; var t; var timer_is_on=0; function timedCount() { document.getElementById('txt').value = c; c = c - 1; if (c <= -1) { mineCount++; var _message = "You have mined " + mineCount + " iron ore" + (((mineCount > 1) ? "s" : "") + "!"); document.getElementById('message').innerHTML = _message; startover(); } } function startover() { c = 10; clearTimeout(t); timer_is_on=0; doMining(); } function doMining() { if (!timer_is_on) { timer_is_on = true; t = setInterval(function () { timedCount(); }, 1000); } } </script> <SPAN STYLE="float:left"> <form> <input type="button" value="Mining" onClick="doMining()"> <input type="text" id="txt"> </form> </SPAN> <html> <center> <div id='message'></div>

• How can I locate the frames of a spritesheet PNG based on this PLIST data?

  - by kitsune

  Someone asked me to reskin a certain game. Now he only sent me the whole sprite PNG and PLIST files of the sprites. He instructed me to rename each sprite with the same name corresponding to each original sprite. The problem is, he gave me the whole sprite sheet instead of each individual sprite and the PLIST. Now yes, I can read the PNG filenames from the PLIST, but I cannot rename the reskin sprites I did because I'm not sure which sprite is boy_gun_3_3.png; there are multiple guns, I don't know which is which. Is there a way to extract individual accurately named individual PNG files from the single sprite sheet using the PLIST?

• To canvas, or not to canvas, when building browser-based games?

  - by Letharion

  Background: I have extensive development background, but the last time I coded a game was many years ago. My Javascript skills are quite limited, and I intend to improve them by building a simple game — Tetris, Pac-man, or something of that complexity level. Question: It seems to me that a fundamental choice I need to make is whether I should render on a <canvas> element or not. With a canvas, I have basic tools for rendering points, lines, and more complex things on top of that. Presumably there are, or will be, also various frameworks to help with this. Without a canvas, I could keep my objects in the DOM-tree, like a regular webpage, only quite complex, with many overlapping elements. Is one approach better than the other? Are they mutually exclusive? How do I know which to pick?

• Is there a way I can sort traffic by page-type based upon URL structure in Google-Analytics or Google Webmaster Tools??

  - by Felix

  I have a local business directory site. I'm trying to segment my incoming traffic by page-type such that i can find out what percentage of traffic is going to zip code pages exclusively and what percentage is going to city/state level pages. I basically want to filter by URL structure to find out what percentage of total traffic zip code pages account for. The reason for doing this is to find out if Does Google Tag Manager help with this? Here are the two URL paths: http://www.example.com/ny/new-york/10011/ http://www.example.com/ny/new-york Thanks all!

• How can I design my classes for a calendar based on database events?

  - by Gianluca78

  I'm developing a web calendar in php (using Symfony2) inspired by iCal for a project of mine. At this moment, I have two classes: a class "Calendar" and a class "CalendarCell". Here you are the two classes properties and method declarations. class Calendar { private $month; private $monthName; private $year; private $calendarCellList = array(); private $translator; public function __construct($month, $year, $translator) {} public function getCalendarCells() {} public function getMonth() {} public function getMonthName() {} public function getNextMonth() {} public function getNextYear() {} public function getPreviousMonth() {} public function getPreviousYear() {} public function getYear() {} private function calculateDaysPreviousMonth() {} private function calculateNumericDayOfTheFirstDayOfTheWeek() {} private function isCurrentDay(\DateTime $dateTime) {} private function isDifferentMonth(\DateTime $dateTime) {} } class CalendarCell { private $day; private $month; private $dayNameAbbreviation; private $numericDayOfTheWeek; private $isCurrentDay; private $isDifferentMonth; private $translator; public function __construct(array $parameters) {} public function getDay() {} public function getMonth() {} public function getDayNameAbbreviation() {} public function isCurrentDay() {} public function isDifferentMonth() {} } Each calendar day can includes many events stored in a database. My question is: which is the best way to manage these events in my classes? I think to add a eventList property in CalendarCell and populate it with an array of CalendarEvent objects fetched by the database. This kind of solution doesn't allow other coders to reuse the classes without db (because I should inject at least a repository services also) just to create and visualize a calendar... so maybe it could be better to extend CalendarCell (for instance in CalendarCellEvent) and add the database features? I feel like I'm missing some crucial design pattern! Any suggestion will be very appreciated!

• How do I set logfile rotation limit for CF8 -out logs?

  - by melikeum

  I'm trying to set the number of logs to keep for the CF -out logs. I found a jrunsvc command line switch to set this but it throws an error saying the value must be at least 1000: jrunsvc.exe -logfileRotationLimit 50 "ColdFusion 8 Application Server" Error: log file rotaion limit must be at least 1000 The default is 200 files which seems excessive but 1000 is even worse. Am I not understanding this value properly? I did set it to 1001 and then I found this registry entry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ColdFusion 9 Application Server\LogFileRotationLimit I'm hesitant to set it there manually in case the value does not equal the number of files to keep.

• What would be the market life of a JVM based software framework?

  - by Nav

  I saw how Struts 1 lasted from 2000 to 2013. I hear that people are moving from Struts 2 to Spring. But for a project that may need to be maintained for a decade or two, would it be advisable to opt for a framework or directly code with servlets and jquery? Can a system architecture really be designed keeping in mind a particular framework? What really is the market life of a framework? Do the creators of the framework create it with the assumption that it would become obsolete in a decade?

  I'm setting up a recurring payment option on my website. I'd like to have two options: Option 1 (for individuals): Fixed $6/mo subscription Option 2 (for organizations): A subscription where the amount is set by the subscriber PayPal's "Subscribe" button does not seem to allow that: When I leave the "Amount" field of the 2nd option empty, I get an error: So, is this not possible? Do all options require fixed amounts?

• How to set up an rsync backup to Ubuntu securely?

  - by ws_e_c421

  I have been following various other tutorials and blog posts on setting up a Ubuntu machine as a backup "server" (I'll call it a server, but it's just running Ubuntu desktop) that I push new files to with rsync. Right now, I am able to connect to the server from my laptop using rsync and ssh with an RSA key that I created and no password prompt when my laptop is connected to my home router that the server is also connected to. I would like to be able to send files from my laptop when I am away from home. Some of the tutorials I have looked at had some brief suggestions about security, but they didn't focus on them. What do I need to do to let my laptop with send files to the server without making it too easy for someone else to hack into the server? Here is what I have done so far: Ran ssh-keygen and ssh-copy-id to create a key pair for my laptop and server. Created a script on the server to write its public ip address to a file, encrypt the file, and upload to an ftp server I have access to (I know I could sign up for a free dynamic DNS account for this part, but since I have the ftp account and don't really need to make the ip publicly accessible I thought this might be better). Here are the things I have seen suggested: Port forwarding: I know I need to assign the server a fixed ip address on the router and then tell the router to forward a port or ports to it. Should I just use port 22 or choose a random port and use that? Turn on the firewall (ufw). Will this do anything, or will my router already block everything except the port I want? Run fail2ban. Are all of those things worth doing? Should I do anything else? Could I set up the server to allow connections with the RSA key only (and not with a password), or will fail2ban provide enough protection against malicious connection attempts? Is it possible to limit the kinds of connections the server allows (e.g. only ssh)? I hope this isn't too many questions. I am pretty new to Ubuntu (but use the shell and bash scripts on OSX). I don't need to have the absolute most secure set up. I'd like something that is reasonably secure without being so complicated that it could easily break in a way that would be hard for me to fix.

• How would I migrate a front page form based site to an IIS7 server? [on hold]

  - by Nick Gilpin

  I have an large html website on a very old server and I'm attempting to move it to a brand new server running IIS7. I've tried moving the entire site to the WWW directory, but then all my forms return "The HTTP verb POST used to access path is not allowed". Additionally, all the solutions I've found online only work on a page by page basis. Is there a simpler/faster way to migrate a large website containing many forms to IIS7? Here is the specific error message: The HTTP verb POST used to access path '/FormServer/Mig/_vti_bin/shtml.dll/admissions/askseaaggie.htm' is not allowed.

• How can I set the rotation of a shape to the same as my image?

  - by BleedObsidian

  The way you set rotations of images is different from setting shape rotations. So how can I make the shape have the same rotation as my image? This is how my image rotates: if(input.isKeyDown(Input.KEY_RIGHT)) { rotate += rotateSpeed * delta; image.rotate(rotate - image.getRotation()); } How can I get the same effect but with a shape? For example: How can I get that rectangle to be at the same rotation as the car?

• where are the default ulimit values set? (linux, centos)

  - by nomercysir

  I have two CentOS (5) servers with nearly identical specs. When I login and do: ulimit -u on one machine, I get unlimited and on the other, 77824 When I run a cron like * * * * * ulimit -u > ulimit.txt I get the same results (unlimited, 77824). I am trying to determine where these are set so that I can alter them. They are not set in any of my profiles (.bashrc, /etc/profile, etc .. these wouldn't affect cron anyway) nor in /etc/security/limits.conf (which is empty). I have scoured google and even gone so far as to do grep -Ir 77824 / but nothing has turned up so far. I don't understand how these machines could have come preset with different limits. I am actually wondering not for these machines, but for a different (CentOS 6) machine which has a limit of 1024, which is far too small. I need to run cron jobs with a higher limit and the only way I know how to set that is in the cron job itself. That's ok, but I'd rather set it system wide so it's not as hacky. Thanks for any help. This seems like it should be easy (NOT) EDIT -- SOLVED Ok, I figured this out. It seems to be an issue either with CentOS 6 or perhaps my machine configuration. On the CentOS 5 configuration, I can set in /etc/security/limits.conf: * - nproc unlimited and that would effectively update the accounts and cron limits. However, this does not work in my CentOS 6 box. Instead, I must do: myname1 - nproc unlimited myname2 - nproc unlimited ... And things work as expected. Maybe the UID specification works to, but the wildcard (*) definitely DOES NOT here. Oddly, wildcards DO work for the 'nofile' limit. I still would love to know where the default values are actually coming from, because by default, this file is empty and I couldn't see why I had different defaults for the two CentOS boxes, which had identical hardware and were from the same provider.

• Need to organize words based on their components, any other way aside from brute force?

  - by Lathan

  I'm not sure if this process has a name. I have some words (about 9,000). They are in Japanese, but I'll try to explain this using English words. I want to categorize the words by the components (in English, letters). A B C act bar play This should create: A: play B: bar C: act Now, 'a' appears in all 3 words, but I want to make sure that each category (letter) has at least word. Now, it would make sense to delete a word after it's used, but there are a few cases where 2 letters make up one word and that's each letter's only word--so I'd like to account for that somehow. Is there an approach for solving this aside from brute force? Dynamic programming perhaps? Even a name for this process (if it exists) would be great.

• Spring boot JAR as windows service

  - by roblovelock

  I am trying to wrap a spring boot "uber JAR" with procrun. Running the following works as expected: java -jar my.jar I need my spring boot jar to automatically start on windows boot. The nicest solution for this would be to run the jar as a service (same as a standalone tomcat). When I try to run this I am getting "Commons Daemon procrun failed with exit value: 3" Looking at the spring-boot source it looks as if it uses a custom classloader: https://github.com/spring-projects/spring-boot/blob/master/spring-boot-tools/spring-boot-loader/src/main/java/org/springframework/boot/loader/JarLauncher.java I also get a "ClassNotFoundException" when trying to run my main method directly. java -cp my.jar my.MainClass Is there a method I can use to run my main method in a spring boot jar (not via JarLauncher)? Has anyone successfully integrated spring-boot with procrun? I am aware of http://wrapper.tanukisoftware.com/. However due to their licence I can't use it. UPDATE I have now managed to start the service using procrun. set SERVICE_NAME=MyService set BASE_DIR=C:\MyService\Path set PR_INSTALL=%BASE_DIR%prunsrv.exe REM Service log configuration set PR_LOGPREFIX=%SERVICE_NAME% set PR_LOGPATH=%BASE_DIR% set PR_STDOUTPUT=%BASE_DIR%stdout.txt set PR_STDERROR=%BASE_DIR%stderr.txt set PR_LOGLEVEL=Error REM Path to java installation set PR_JVM=auto set PR_CLASSPATH=%BASE_DIR%%SERVICE_NAME%.jar REM Startup configuration set PR_STARTUP=auto set PR_STARTIMAGE=c:\Program Files\Java\jre7\bin\java.exe set PR_STARTMODE=exe set PR_STARTPARAMS=-jar#%PR_CLASSPATH% REM Shutdown configuration set PR_STOPMODE=java set PR_STOPCLASS=TODO set PR_STOPMETHOD=stop REM JVM configuration set PR_JVMMS=64 set PR_JVMMX=256 REM Install service %PR_INSTALL% //IS//%SERVICE_NAME% I now just need to workout how to stop the service. I am thinking of doing someting with the spring-boot actuator shutdown JMX Bean. What happens when I stop the service at the moment is; windows fails to stop the service (but marks it as stopped), the service is still running (I can browse to localhost), There is no mention of the process in task manager (Not very good! unless I am being blind).

• More elegant way to make a C++ member function change different member variables based on template p

  - by Eric Moyer

  Today, I wrote some code that needed to add elements to different container variables depending on the type of a template parameter. I solved it by writing a friend helper class specialized on its own template parameter which had a member variable of the original class. It saved me a few hundred lines of repeating myself without adding much complexity. However, it seemed kludgey. I would like to know if there is a better, more elegant way. The code below is a greatly simplified example illustrating the problem and my solution. It compiles in g++. #include <vector> #include <algorithm> #include <iostream> namespace myNS{ template<class Elt> struct Container{ std::vector<Elt> contents; template<class Iter> void set(Iter begin, Iter end){ contents.erase(contents.begin(), contents.end()); std::copy(begin, end, back_inserter(contents)); } }; struct User; namespace WkNS{ template<class Elt> struct Worker{ User& u; Worker(User& u):u(u){} template<class Iter> void set(Iter begin, Iter end); }; }; struct F{ int x; explicit F(int x):x(x){} }; struct G{ double x; explicit G(double x):x(x){} }; struct User{ Container<F> a; Container<G> b; template<class Elt> void doIt(Elt x, Elt y){ std::vector<Elt> v; v.push_back(x); v.push_back(y); Worker<Elt>(*this).set(v.begin(), v.end()); } }; namespace WkNS{ template<class Elt> template<class Iter> void Worker<Elt>::set(Iter begin, Iter end){ std::cout << "Set a." << std::endl; u.a.set(begin, end); } template<> template<class Iter> void Worker<G>::set(Iter begin, Iter end){ std::cout << "Set b." << std::endl; u.b.set(begin, end); } }; }; int main(){ using myNS::F; using myNS::G; myNS::User u; u.doIt(F(1),F(2)); u.doIt(G(3),G(4)); } User is the class I was writing. Worker is my helper class. I have it in its own namespace because I don't want it causing trouble outside myNS. Container is a container class whose definition I don't want to modify, but is used by User in its instance variables. doIt<F> should modify a. doIt<G> should modify b. F and G are open to limited modification if that would produce a more elegant solution. (As an example of one such modification, in the real application F's constructor takes a dummy parameter to make it look like G's constructor and save me from repeating myself.) In the real code, Worker is a friend of User and member variables are private. To make the example simpler to write, I made everything public. However, a solution that requires things to be public really doesn't answer my question. Given all these caveats, is there a better way to write User::doIt?
