• Alternative ways to construct maps

  - by sideways8

  I've searched around and it seems like most people are using tile-based map systems. I suppose this question is more theoretical than practical (I am not very concerned about memory or performance speed), but I want to know: what other ways can a map be created in a game? A map being a graphic representation of terrain that can be navigated, has entrances and exits, and boundares (no-go zones). Besides using text files to store and arrays to load tile data, one idea I had was to store a map entirely as a graphic file and use queries on the pixel colour to determine boundaries (ie, you can only move in a certain direction if the way is bright enough in that direction). What other creative map systems are out there?

• Moving multiple objects on a map

  - by Dave

  I have multiple objects on my isometric game, for example, NPC's doing path finding automatically to walk around the map. Now there could be any number of them from 0 to infinity (hypthetical as no PC could handle that). My question is: is simply looping each one individually the smartest way to animate them all? Surely as the number of units increases you will notice a lag occuring on units near the end of loop still "waiting" for their next animation movement. The alternative is a swarm algorithm to move all objects together. Is that a smarter idea or do both situations apply depending on the circumstances of the game?

• How to tell Wine that I have changed CD when mounting them virtually on a netbook with no CD drive?

  - by glenatron

  I have been trying to catch up with some of the old games from way back that are about right for my little Aspire One netbook through Wine. I've run into a problem Baldurs Gate, however, which is that I can't change CD. Obviously, I don't have a CD drive, so I have copied the CD content onto an external hard drive and I'm using a mount command with the loopback option to persuade the game that the CD is present. This allowed installation to work correctly and works fine to run it and to play the content from the first CD. However, when the game asks for CD2, I'm stuck. If I mount the CD2 ISO to the CD Rom path it doesn't appear to respond, whether or not I have first unmounted CD1. When I ask Wine to show me the CD drive it contains the right data, but it seems as though whatever signal would be interpreted by Windows to mean the CD drive has been closed isn't being sent. Does anyone know of a way to do this, or am I barking up the wrong tree and there is something else I need to do?

• Open file with java application [migrated]

  - by Giaphage47

  I am using Ubuntu. I would like to have a user be able to double-click (or whatever they have set to open a file) on the save file for a java game i'm making, and have the game start and automatically load the save. How could I make the game launch instead of opening the file, and then pass the save's file name or location as an argument? Would i have to have the game create a new mime type the first time it ran, or something similar, so that Ubuntu knows what to do with the save when the user tries to open it?

• Cocos2D Terminal Application

  - by Hasyimi Bahrudin

  Is it possible to create a terminal application which uses cocos2d? I've tried to make one using cocos2d 2.x, but it requires a MacGLView to be initialized. I need it so that I could program a terminal application that generates a screenshot given a TMX file and an optional preferred width or height parameter (for resizing). Then I can automate the generation of map previews for my game, instead of manually taking screenshots. It's not practical to load the actual TMX and resize it inside the game (what I'm currently doing), because each TMX file has 7 layers, my tile sheet is huge, and I have lots of levels.

• how much knowledge do you need to call yourself a programmer?

  - by nore

  There is a guy who calls himself c/c++ programmer, but what does he actually know? What knowledge about c++ does he have because there are so much to know about c/c++. So he knows the core language? He knows visual c++? He knows how to program with WIN API? He knows how to program in linux with gtk? Network programming? The real question is: What do you need to know, to be called a c/c++ programmer ,because I know c and I really do not feel like I own the power of programming... please illuminate my path.

• What are the dis-advantages of installing the ssl certificate for the naked domain?

  - by user1744649

  I might buy an SSL certificate for my sie. I know that it will help me in many ways. But will there be dis-advantages also? eg. If I load an image from another server (using plain http), will that alert the customer saying something is wrong? Will I be able to use all existing codes like phpbb, awstats etc without a problem? Will there be any issue if redirect a page from my domain.com to my subdomain.domain.com using a meta refresh or .htaccess? Will there be any issue if redirect a page from my subdomain.domain.com to my domain.com using a meta refresh or .htaccess? Any other issue that I might get into? Thanks.

• How do I replace Unity?

  - by Krista O'Connors

  I wanted to use Ubuntu 12.04 for its long term support. But I cannot stand Unity. I cannot find a way to replace it with compizconfig, so I tried replacing it with Lubuntu. When I restarted my computer started to load lubuntu, then just went right on with ubuntu as if nothing had happened. Likewise, it shows lubuntu when it shuts down. What is the deal? I'm confused here, is ubuntu 12.04 supposed to be an operating system or a desktop interface? Can I even run ubuntu with a Lubuntu interface? Is there a way to do this in compizconfig that I should be doing instead?

• Should an image be able to resize itself in OOP?

  - by ChocoDeveloper

  I'm writing an app that will have an Image entity, and I'm already having trouble deciding whose responsibility each task should be. First I have the Image class. It has a path, width, and other attributes. Then I created an ImageRepository class, for retrieving images with a single and tested method, eg: findAllImagesWithoutThumbnail(). But now I also need to be able to createThumbnail(). Who should deal with that? I was thinking about having an ImageManager class, which would be an app-specific class (there would also be a third party image manipulation reusable component of choice, I'm not reinventing the wheel). Or maybe it would be 0K to let the Image resize itself? Or let the ImageRepository and ImageManager be the same class? What do you think?

• Requirements Gathering Form?

  - by Daveo

  Do you use a standard form to gather requirements from a customer prior to making a website? If so what are the questions you ask? For example Purpose of Website: (sell products, reduce number of enquires, reduce work load, etc) Do you have you’re an existing logo?

Do you have a colour theme for your logo, business cards, shop you would like to keep on the website Do you have photos you can provide of your Products? etc Ofcause it would need to be tweaked slightly for each customer but I was looking for a generic document as a baseline.

• How do I duplicate a Box2d simulation, mid-simulation?

  - by Whyte

  I want to serialize the state mid-game, send it over the network to an identical computer (same CPU, same OS, same binary), load it there, and have the two games run in tandem doing the exact same simulation, without one of them drifting off and going haywire. In short: I want pop-in, pop-out networking support on my HIGHLY physics-intensive game, where sending object coordinates every few seconds is impossible, due to having thousands of objects, and many clients. I tried this with Box2D, and saving an object's location/velocity/etc wasn't enough... there's internal state that's not accessible through any public methods. My current workaround is to force EVERY client to save its entire worldstate and reload it from scratch, whenever a new player connects... but this is obviously bad practice, because it hangs the game for everyone whenever someone new connects. However, it works, with zero desynchronization. So, anyone know of any other techniques that can help me? Or should I just kiss my project goodbye?

• How to copy or sync music on iphone 3gs on ubuntu 14.04?

  - by user276842

  I’m using Ubuntu 14.04 and want to copy music to/on my iPhone 3gs. I already installed the actual mobile device, but neither Rhythmbox nor gmusicbrowser show my phone. Only on Gigolo I can see it, and transfer data, but the music I copy is not working on my phone. On Amarok I get at least this information: termined mount-point path to /tmp/kde-cafer/amarok/imobiledevice_uuid_882ba1378fe4eb76e98ad6582dcad031c2247664 calling `ifuse "-u" "882ba1378fe4eb76e98ad6582dcad031c2247664" "-ofsname=afc://882ba1378fe4eb76e98ad6582dcad031c2247664" "/tmp/kde-cafer/amarok/imobiledevice_uuid_882ba1378fe4eb76e98ad6582dcad031c2247664"` with timeout of 10s command failed to start within timeout Failed to mount iPhone on /tmp/kde-cafer/amarok/imobiledevice_uuid_882ba1378fe4eb76e98ad6582dcad031c2247664 Does anyone have an idea?

• How to calculate shot angle and velocity to hit a moving target?

  - by Guen

  I am developing a 2D Android game and I am making an aiming algorithm for AI projectiles to hit enemies either following a path, or free moving. At the moment it just calculates where the target will be after a distance and fires a projectile to meet it at that distance. Of course this means varying the projectile speed to meet the target. Does anyone have any tips for a simple-ish algorithm (optimal-ish) to calculate when the projectile needs to fire and where it needs to aim if it can only travel at a constant velocity? Say the projectile goes twice the speed of the target? The only way I can think of involves searching and seems quite large.

• How well supported is the ATI graphics on a Sony VAIO SA?

  - by whoami

  This is the first time i will be buying a laptop/desktop to use as a Ubuntu platform with ATI. Now i did notice a while back that ATI drivers were not in cahoots with Linux as of yet. I am just wondering if any one is still experiencing ATI issues, or this is no longer the case. I am looking to spend money on a laptop Upgrade, but I don't want to spend a screw load of money just to find out I can only use windows and my Graphics driver does not work. So the Question is: What's ATI Support like on Ubuntu 10.10 Here is what im thinking of buying http://www.gadgetfreak.gr/wp-content/uploads/2011/02/SB_S08_keyboard_B_us_FP-1024x716.jpg, If any one has the Sony VAIO SA Series and installed Ubuntu on it, please do share your story, about driver problems. On a side note my old Sony S-Series which im using now, i never got the fingerprint reader or the webcam working on it, has any one been able to do this for the new models? I preferably dont care about the fingerprint reader but do care about the webcam.

• Domain Model and Querying

  - by Tyrsius

  I am new to DDD, having worked only in Transaction-Script apps with an anemic model, or just Big Balls of Mud, so please forgive any terminology I abuse. I am trying to understand the proper separation between the domain model and the repository. What is the proper way to construct a domain object that is coming from a database, assuming the (incredibly simplified) need to query for objects by status (returns enumerable), or by ID. Should a factory be building the objects, exposing methods for GetByStatus() and GetByID(), using a DIed repository? Should a repository be called directly, knowing how to build a domain model from the DTO? Should the domain model have a constructor for get by ID, using a DIed repoistory to load the initial state, using some other (?) method for the list? I am not really sure what the best way would be, and this question has an answer advocating each one (these are certainly mutuallu exclusive).

• Uninstalling Wubi

  - by DvoglaviOrao3

  I installed wubi in a 30GB partition and I wanted to delete that so that I could install Ubuntu via usb with a larger partition. So I went to the control panel to find Ubuntu but it wasn’t there. I decided to go into the c drive and deleted the Ubuntu file. BUT now every time i boot up it asks me to choose windows 7 and Ubuntu (like I still have dual boot) and if I choose Ubuntu it says "windows could not find this file" and then says the path of the file. what should I do to remove this old wubi/ubuntu?

• Will these tool tips get me penalized?

  - by user21100

  I have a page of 10 products. Each product has a list of (7) features associated with it. If a user hovers over the name of the feature, (ex., "Moisture resistance), a tooltip description displays. The descriptions ( a sentence or two), are loaded once on the page using Javascript, but the titles are not, so I essentially have a bunch of redundant tool tip titles. I am concerned this will look like keyword stuffing to the bots. Anyone know about this? Maybe I should load the feature titles with javascript as well?

• Access Denied

  Surely, now that PowerPivot has led the way, it is time for Microsoft to offer a new RAD package for database application development; namely an Excel-based front end for SQL Server Express. In that way, we'll have a powerful and familiar front end, to a scalable database, and a clear upgrade path when an app takes off and needs to go enterprise....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How do you enhance your websites speed without compromising the design and access?

  - by Thorn007

  How do you enhance your websites load speed without killing the design and accessibility? File compression, CDN, Gzip? What are the best tools for doing so? For example, Google has optimized their site without compromising the design. Also, many website can kill the purity of their images with compression. Is there a way, more or lest best practice, to increase speed without compromising the design and accessibility? Note: sorry for being so vague but I don't know how else to phrase this question.

• SSL on multiple directories

  - by Shredder

  I have a website that is http, but has a port set up for https for a specific directory that is for the shopping cart. Now I'd like to use our SSL on a different directory in the same site as well. How can I go about configuring that? I have tried looking into all of the config files as well as the docs and cannot figure it out. I tried setting this in httpd.config as well <VirtualHost 127.0.0.1:[ssl port]> #also tried *:[ssl port] and [actual IP]:[ssl port] ServerAdmin [email protected] DocumentRoot "C:/path/sslNeededDir" ServerName www.example.com </VirtualHost> hoping that it would cause pages in this directory to use ssl port and become https, but that didn't do anything. Any help is greatly appreciated. Update: This finally got migrated over. I'm still looking for a solid answer on this. If anyone could help me, it would be greatly appreciated.

• Assigning a different texture based on picking(XNA)

  - by Thomas Carmichael

  I'm making a game using XNA. I have some simple objects like cube and sphere, and I would like to change the texture of one face of these objects based on picking. That is, when the cursor is over one face, it turns red. The only way I've seen to do this is to overload the content processor as here: http://xbox.create.msdn.com/en-US/education/catalog/sample/picking_triangle but it seems like it shouldn't be this complicated. I'm using .x models, and would like to be able to implement this for more complex models in the future beyond cubes/spheres/etc. Is this the best/only way to go about it? I'll figure that out if that's what is necessary, but it seems that there would be a simpler solution to load a different texture to a face than I've seen, I just don't know what it is.
