  • Multiplayer tile based movement synchronization

    - by Mars
    I have to synchronize the movement of multiple players over the Internet, and I'm trying to figure out the safest way to do that. The game is tile based, you can only move in 4 directions, and every move moves the sprite 32px (over time of course). Now, if I would simply send this move action to the server, which would broadcast it to all players, while the walk key is kept being pressed down, to keep walking, I have to take this next command, send it to the server, and to all clients, in time, or the movement won't be smooth anymore. I saw this in other games, and it can get ugly pretty quick, even without lag. So I'm wondering if this is even a viable option. This seems like a very good method for single player though, since it's easy, straight forward (, just take the next movement action in time and add it to a list), and you can easily add mouse movement (clicking on some tile), to add a path to a queue, that's walked along. The other thing that came to my mind was sending the information that someone started moving in some direction, and again once he stopped or changed the direction, together with the position, so that the sprite will appear at the correct position, or rather so that the position can be fixed if it's wrong. This should (hopefully) only make problems if someone really is lagging, in which case it's to be expected. For this to work out I'd need some kind of queue though, where incoming direction changes and stuff are saved, so the sprite knows where to go, after the current movement to the next tile is finished. This could actually work, but kinda sounds overcomplicated. Although it might be the only way to do this, without risk of stuttering. If a stop or direction change is received on the client side it's saved in a queue and the char keeps moving to the specified coordinates, before stopping or changing direction. If the new command comes in too late there'll be stuttering as well of course... I'm having a hard time deciding for a method, and I couldn't really find any examples for this yet. My main problem is keeping the tile movement smooth, which is why other topics regarding synchronization of pixel based movement aren't helping too much. What is the "standard" way to do this?

  • What is the lowest ICQ number that was ever used? [closed]

    - by zzatkin
    I'm not sure if this is the correct place to post this question, so feel free to move it. I was wondering, since this is a tech-orientated questionnaire website, that someone would know what the lowest ICQ number ever used was. From doing some research, I found a lot of mixed answers, and I also found out that there was a beta period where the first few thousand numbers were used, but then they all got deleted or stopped being used.

  • Help decide HTML5 library or framework

    - by aoi
    I need a library or framework for small html5 contents and animation centric softwares. My priority isn't things like physics or network. I need fast rendering speed, support for touch event and most of all maximum compatibility across various platforms, including ios and android. I am pondering upon sprite js, crafty js, and kinetic js. But i can't really test the platform compatibilities, so can someone please tell me which one covers the maximum number of platforms, and if there are any better free alternatives?

  • Script + template to generate static web site?

    - by user702
    After giving it more thought, I don't actually need a PHP-based CMS for a small, static web site. Does someone know of a good solution that can run on Windows that would take basic HTML pages and JPG pictures, combine those with a template, and generate a static site ready to be FTPed to an web server? Thank you. Edit: For those looking for the same information, here's some well-known tools to create a static site: http://get-simple.info/ http://gpeasy.com/How_Easy http://textpattern.com/features http://nanoc.stoneship.org/ http://www.movabletype.com/

  • Getting Started on Building a Website Or Blog

    If you are looking to build a website or blog then you have to have hosting. There is no way of getting around hosting unless you want to use a free service like WordPress.com or Blogger in which case you do not get a distinguished domain name. Your domain name would be a sub domain name. For example: yourname.wordpress.com would be your specific URL. This is not really an option for someone even remotely serious about owning a website or blog.

  • Trainee programs for foreigner in EU [closed]

    - by user63970
    Maybe this is the wrong site for asking that, but I didn't find better. I heard a lot about programs for young IT specialists in EU from other countries, my residence is Ukraine. We have several organizations that provide info about them, but you must pay quite a lot for them to only show you the list of vacancies. Maybe someone knows about companies in EU that are willing to take young programmers for trainee or junior vacancies from non-EU countries? I am interested in C++ development.

  • Empirical evidence regarding testability

    - by Xodarap
    A google scholar search turns up numerous papers on testability, including models for computing testability, recommendations for how ones code can be more testable, etc. They all come with the assertion that more testable code is more stable, but I can't find any studies which actually demonstrate this. Can someone link me to a study evaluating the effect of testable code vs. quality? The closest I can find is Improving the Testability of Object Oriented Systems, which discusses the relationship between design flaws and testability.

  • NUnit Random Module

    - by Tra5is
    I've noticed something curious. When I attach the VS2010 debugger to the nunit.exe running process I see a loaded module with no path and a randomly generated filename. I tried attaching WinDBG to the exact same instance of NUnit.exe and the module is NOT listed in the module list. I also can't find anything with Google so I'm hoping someone here could help out. Is this normal NUnit behavior or is something sneaky going on? Some examples of the module name: 1xmsg0gj x4max0ed koh9hmef

  • 'Unable to mount Filesystem' Error

    - by Charles
    Trying to extract data from a 'bricked' Western Digital MyBook Live 2tb drive. I came across a forum that advised to use Ubuntu (booted from a CD) on my Macbook. Managed to download and create a boot CD for Ubuntu (like this little operating system btw). Booted the machine with the CD and plugged the drive (which I had extracted from it's casing and placed into a external USB SATA case & plugged to the laptop). The drive is seen by Ubuntu but each time I click on the drive, it gives me the following error: Unable to mount 2.0 TB Filesystem Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error In some cases useful info is found in syslog -try dmesg | tail or so I am new to this and spent quite some time searching this site to see if I could find a solution to this problem without troubling anyone. I came up with a few that came close but some of the questioners mentioned that they had lost data...which scared me from going further. I need to basically extract 1 particular folder from the drive. If I can get to mount this volume 'sdb4', there is a folder called 'My_Work' which I need to back up. The rest I have/had a copy of. When I typed in dmesg | tail...I got several lines..but I think ones that are relevant are: [ 406.864677] EXT4-fs (sdb4): bad block size 65536 [ 429.098776] hfs: write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only [ 439.786365] hfs: write access to a journaled filesystem is not supported, use the force option at your own risk, mounting read-only [ 445.982692] EXT4-fs (sdb4): bad block size 65536 [ 1565.841690] EXT4-fs (sdb4): bad block size 65536 I read somewhere to try/check 'sudo fdisk -l /dev/sdb4'. It gave me the following result: Disk /dev/sdb44: 1995.8 GB, 1995774623744 bytes 255 heads, 63 sectors/track, 242639 cylinders, total 3897997312 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdb4 doesn't contain a valid partition table This is where I reached and got frustrated and decided to try & get help on this without digging myself deeper into a hole! I understand that the answer may already be out there. If so, could someone please point me in the right direction. And if not, could someone please resolve (if possible) my situation!

  • Separating logic and data in browser game

    - by Tesserex
    I've been thinking this over for days and I'm still not sure what to do. I'm trying to refactor a combat system in PHP (...sorry.) Here's what exists so far: There are two (so far) types of entities that can participate in combat. Let's just call them players and NPCs. Their data is already written pretty well. When involved in combat, these entities are wrapped with another object in the DB called a Combatant, which gives them information about the particular fight. They can be involved in multiple combats at once. I'm trying to write the logic engine for combat by having combatants injected into it. I want to be able to mock everything for testing. In order to separate logic and data, I want to have two interfaces / base classes, one being ICombatantData and the other ICombatantLogic. The two implementers of data will be one for the real objects stored in the database, and the other for my mock objects. I'm now running into uncertainties with designing the logic side of things. I can have one implementer for each of players and NPCs, but then I have an issue. A combatant needs to be able to return the entity that it wraps. Should this getter method be part of logic or data? I feel strongly that it should be in data, because the logic part is used for executing combat, and won't be available if someone is just looking up information about an upcoming fight. But the data classes only separate mock from DB, not player from NPC. If I try having two child classes of the DB data implementer, one for each entity type, then how do I architect that while keeping my mocks in the loop? Do I need some third interface like IEntityProvider that I inject into the data classes? Also with some of the ideas I've been considering, I feel like I'll have to put checks in place to make sure you don't mismatch things, like making the logic for an NPC accidentally wrap the data for a player. Does that make any sense? Is that a situation that would even be possible if the architecture is correct, or would the right design prohibit that completely so I don't need to check for it? If someone could help me just layout a class diagram or something for this it would help me a lot. Thanks. edit Also useful to note, the mock data class doesn't really need the Entity, since I'll just be specifying all the parameters like combat stats directly instead. So maybe that will affect the correct design.
