• RPG Item processing

  - by f00b4r

  I started working on an item system for my (first) game, and I'm having a problem conceptualizing how it should work. Since Items can produce a bunch of potentially non-standard actions (revive a character vs increasing some stat) or have use restrictions (can only revive if a character is dead). For obvious reasons, I don't want to create a new Item class for every item type. What is the best way to handle this? Should I make a handful of item types (field modifiers, status modifiers, )? Is it normal to script item usage? Could (should?) this be combined with the above mentioned solution (have a couple of different sub item types, make special case items usage scripted)? Thanks.

• Good university for computer science with plans for Game Dev.

  - by DukeYore

  I am starting my Computer science degree at a local community college in Programming using C++. However, i will be transferring to a 4-year university. Does anyone have any insight on university programs? I know Cal State Fullerton has a degree with a minor in Game Dev. however, is that as important as getting a degree from a really great school? if i could shoot for something like Cal Poly would that be better? Or even Stanford or SF state being so close to so many gaming companies up there in the bay area? thank you in advance for any guidance.

• Highlighting new rows in ADF Table

  - by Sireesha Pinninti

  About This article explains how to hightlight newly inserted rows in an ADF Table without writing any extra java/javascript code.IntroductionSometimes we may wish to give more clarification to the end user by differentiating between newly inserted rows and the existing rows(i.e the rows from DB) in a table by highlighting new rows in different color as in the figure shown below. SolutionWe can achieve the same by giving following EL to inlineStyle property of every column inside af:table: #{row.row.entities[0].entityState == 0?'background-color:#307D7E;':''}ExplanationHere is the explanation for row.row.entities[0].entityState given inside EL which returns the state of the row(i.e, New, Modified, Unmodified, Initialized etc.)row - Refers to a tree node binding(instance of FacesCtrlHierNodeBinding) at runtimerow.row - Refers to an instance of row that the tree node is based onrow.row.entities[0] - Gets the Entity row at zeroth index. In most of the cases, the table will be based on single entity. If your table is based on multiple entities then the index needs to be given accordingly.row.row.entities[0].entityState - Gets Entity Object's current Entity-state in the transaction.(0 - New, Modified - 2, Unmodified - 1, Initialized - -1,  etc.,)

• XNA When to call LoadContent

  - by Peteyslatts

  I have an enum in my game that denotes the game state ie MainMenu, InGame, GameOver, Exit and I was wondering if it would be advisable to add a new one in for PrepGame - in which the game creates viewports for however many players there are, creates the battlefield etc. I feel like this is a good idea except for one thing: should I make a call back to LoadContent() in this state? I could just put a switch statement in the LoadContent for my currentGameState. If it equals PrepGame load things like the skybox, ship models, texures, HUD graphics etc. Or is it a good idea to create an Asset Manager class in the first call to LoadContent() and load everything then. I feel like both approaches have different benefits: faster, but more load times vs slower initial load time, but then all my objects are referencing the same variables so I only have to load each on once. Any help is greatly appreciated. Thanks, Peter

• Geolocation Blocking and SEO

  - by Mahesh

  I'm in process to block a particular geolocation from accessing my site. But i am not sure if this is going to raise any flags on my website. Basically i'm getting lots of spam from particular state and there are some webmaster copying my content without any attribution or backlink. I feel that is enough and i wish to save my bandwidth on that state or geolocation. So my question is how to block particular geolocation ? Do you have any suggestions for php scripts that help block particular geolocation ? and another question: if there are any SEO disadvantages ?

• kubuntu: wireless manager can't find any networks

  - by timuçin

  I just installed Kubuntu 12.10 and as I knew my wireless driver would not be recognized, I installed it manually through here. I suppose I shall mention that I also had to do this. The driver worked just fine until I restarted my system. Since then I can't even start over. My wireless card is realtek 8723 The oly lead I have is this piece of log: 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> wpa_supplicant started 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0) supports 4 scan SSIDs 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0): supplicant interface state: starting -> ready 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0): device state change: unavailable -> disconnected (reason 'supplicant-available') [20 30 42] 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <warn> Trying to remove a non-existant call id. 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0): supplicant interface state: ready -> inactive 11/14/12 07:35:21 AM timucin-W150ER NetworkManager[989] <info> (wlan0) supports 4 scan SSIDs I feel really bad that I have been trying so many things and even while I am trying them I get a problem at every step. I am really frustrated. You can the time in the logs, I didn't get up early. Just needed to share my feelings. Even the ethernet cable I have use is short for God's sake, I have had to sit at this massively uncomfortable posture for hours. edit: I discovered something interesting. When I boot my windows I see that my wireless manager says "disconnected" now. However when I start ubuntu after windows and modprobe rtl8723e wireless works just fine. Then again, when I restart ubuntu I am back where I have started. So now I have to start windows, restart my machine and do the modprobe thing to see wireless networks.

• How to access / query Team Foundation Server 2012 with Odata?

  - by cseder

  I've tried to find a solution for this for hours now, and I'm getting the same results in the end, asking me to install a lot of Azure and other stuff, plus running some example project .sln that I can't open with my 2012 version of Visual Studio. So, I'm pretty much stuck, and have some pretty straight forward questions regarding this: Does TFS 2012 include the Odata service in any way, so that I don't have to install it? If not, how can I install a NATIVE 2012 version of the Odata service for TFS 2012? Is it possible that I'm aiming for the wrong target here? I'm looking for a solution to the following: I have a TFS 2012 Server that I need to be able to create Work Items on programatically, based on data from our Help Desk system. Then I need to query these Work Items for changed status since its creation, and update the Help Desk Database. Am I better off using the "regular" TFS API? I was kinda thinking that the Odata way was more "future proof", but I'm not sure...

• How to deal with characters picking up and dropping objects in a 2D game

  - by pm_2

  I'm quite new to game development, so would like to get a consensus on methods of doing this. My game features a 2D character that is able to pick up and drop objects, for example, a stick. My question is: is it advisable / possible to manipulate the image of the character and image of the stick to make it look like the character is now carrying a stick; or is it best to have a separate sprite sheet for the character with the stick and the character without? EDIT: To be clear - I have a lot of characters, with a few items (4 separate items and over 20 characters)

• Scuttlebutt Reconciliation from "Efficient Reconciliation and Flow Control for Anti-Entropy Protocols"

  - by Maus

  This question might be more suited to math.stackexchange.com, but here goes: Their Version Reconciliation takes two parts-- first the exchange of digests, and then an exchange of updates. I'll first paraphrase the paper's description of each step. To exchange digests, two peers send one another a set of pairs-- (peer, max_version) for each peer in the network, and then each one responds with a set of deltas. The deltas look like: (peer, key, value, version), for all tuples for which peer's state maps the key to the given value and version, and the version number is greater than the maximum version number peer has seen. This seems to require that each node remember the state of each other node, and the highest version number and ID each node has seen. Question Why must we iterate through all peers to exchange information between p and q?

• Hidden text and links appearing just on click for SEO?

  - by CamSpy

  I am working on a site that has neat clean/minimalistic design/layout. Menu items are "hidden" behind an icon, to see them, users need to click on that icon to get a javascript toggled overlay with the list of menu items. Then there are blocks with photos and users need to click on a small icon/button on each of them to get a block of text shown for each of the photo. While I don't like such "design" myself, making me click lots of time just to read, I also think that for SEO purpose this model is really wrong. Is such model bad for SEO? Are there ways to keep design like this but have "safe" methods of displaying text content on click that will not hurt SEO?

• ASP.NET MVC Portable Areas - Can they communicate and be used as a plugin-like architecture?

  - by Beton

  I'll get straight to the point: I was wondering if there is a common pattern to use portable areas as a components of a plugin-like architecture. Example: We've got 3 plugins (portable areas) packaged and distributed via NuGet feed. Each of them is following the standard MVC structure (has it own Models, Views and Controllers). Lets say login form, header and footer. What I was wondering if there is a way to make them communicate. For example: when user logs on, login plugin executes it own logic, logs the user and then it updates the state of the header plugin with changes it state accordingly. Thanks in advance.

• SEO penalty for landing page redirects

  - by therealsix

  Using ebay as an example- lets say I have a large number of items whose URLs' look like this: cgi.ebay.com/ebaymotors/1981-VW-Vanagon-manual-seats-seven-/250953153841 I want to give my client the ability to put links to these items on their website EASILY, without knowing or checking my URL. So I created a redirect service that will map their identifier with my URL: ebay.com/fake_redirect_service/shared_identifier9918 would redirect to the link above. This works great- my clients can easily setup these links with information they already have, and the user will see the page as usual. So on to the problem... I'm concerned that this redirecting service will have a negative impact on my SEO ranking. Having a landing page redirect you immediately to a different URL seems like something a typical spam site would do. Will this hurt me? Any better solutions?

• Character coding / programming

  - by Jery

  Lately I tryed a few times to create characters for some games, but at some certain point (especially when collision detection came in) everything became messy and the interaction between chars, the world and certain items had a lot of bugs. So here is my question, how do you ussualy keep track of actions that your character is allowed to do, or more in general do you have some links / advices how to set up a char efficiantly? I´m working on a char right now, who should at least be able to run, jump, pick items up and use different fighting animations. Most ideas I came up with until now use some kind of action.priority / action.duration system to determain whats possible and what not, or a "action-manager" which defines for every action what is possible from that action on but it all doesnt work that well together.

• Context Menu for add and remove datalist column [migrated]

  - by Kadir Ozgur

  When I right click on Datalist Columns then a context menu appears whose items are add columns, remove column etc. When I removed a column and if I want to remove one more column then it shows me to remove previous column. Everytime, it shows me to remove the previous ones. if (mnu.Name.StartsWith("Rem")) { //getview(); //datalist.Items.Refresh(); //rows.Clear(); //datalist.ItemsSource = rows; int id = listwork.dispidx(util.valint(/*mnu.Name.Substring(3)*/util.valint(mnu.Tag)), ListWork.eArtIdx.dispord); int delid = listwork.delcol(id); GridViewColumnCollection gw = getview().Columns; if (delid >= 0 && delid < gw.Count) gw.RemoveAt(delid); listsortnr = 0; //weil wir ja Colonnen gelöschte haben showsortlist(listwork.querydef.Sortcol); //rows.Clear(); DoRefresh(); }

• Player rewards in games where you normally have nothing to purchase

  - by PeterK

  In many games there are rewards such as gold coins, points, etc. When these rewards can be used to purchase in-game items, it motivates the player to keep playing. Let's say we have an online game, poker, Yatzy etc. What type of reward would keep the players playing if there are few in-game items available to buy, or none at all? What I am looking for is a reward system that entices the players to play more in a game environment where there isn't that much to purchase. For example, there isn't much to buy in a poker or Yatzy game with the gold you win. I guess having some titles that are added to the userid is one way, or maybe purchasing a logo for the id... A leaderboard is another. Any thoughts on this?

• Processing a list of atomic operations, allowing for interruptions

  - by JDB

  I'm looking for a design pattern that addresses the following situation: There exists a list of tasks that must be processed. Tasks may be added at any time. Each task is wholly independent from all other tasks. The order in which tasks are processed has no effect on the overall system or on the tasks themselves. Every task must be processed once and only once. The "main" process which launches the task processors may start and stop without warning. When stopped, the "main" process loses all in-memory data. Obviously this is going to involve some state, but are there any design patterns which discuss where and how to maintain that state? Are there any relevant anti-patterns? Named patterns are especially helpful so that we can discuss this topic with other organizations without having to describe the entire problem domain.

• Inventory Item Exist checker

  - by Annalyne

  I have a question regarding declaring my inventory. I made it a string named inventory, with a constant number as its max value. The thing is, I want the user to use an item if he / she gains an item. The problem is, I do not know what syntax should I use to determine if the user has an item and use that item. Here's my code I just started: so declaring the inventory: const int MAX_ITEMS = 15; string game_inventory [MAX_ITEMS]; int itemnum = 0; I have some items like potion, antidote, gems and others. I use the: game_inventory[itemnum++] = "Potion" to place items in my inventory. If I want to use the potion, IF I HAVE one, how can i make a function to check whether I have a potion or anything and use it?
