• Best way to update UI when dealing with data synchronization

  - by developerdoug

  I'm working on a bug at work. The app is written in Objective-C for iOS based device, for the iPad. I'm the new guy there and I've been given a hard task. Sometimes, the UIButton text property does not show the correct state when syncing. Basically, when the app is syncing, my UI control would say "Syncing" and when its not syncing it'll display "Updated @ [specific date]". Right now there is a property on the app delegate called "SyncInProgress". When querying / syncing, occurring on background thread, it updates a counter. The property will return a bool checking expression 'counter 0'. There are three states I need to deal with. Sync has started. Sync is updating tables. Sync finished. These items need to occur in order. My coworker suggested to take a state based approach instead of just responding to events. I'm not sure about how to go about that. Would it be best to have the UI receive a notification to determine what state its in or to pull every so often if state changed? Here are two posts that I put on stackoverflow, in the last few days, that relate to this. http://stackoverflow.com/questions/11025469/ios-syncing-using-a-state-approach-instead-of-just-reacting-to-events http://stackoverflow.com/questions/11037930/viewcontroller-when-viewwillappear-called-does-not-always-correctly-reflect-stat Any ideas that anyone might have to very much appreciated. Thanks, developerDoug

• Design difficulty for multiple panel forms [closed]

  - by petre

  I have form that consists of multiple panel on the right, a treeview on the left and a terminal richtextbox on the bottom. When i click on a node of the treeview i bring up the panel that is attached with the node. For example i have 10 nodes on the treeview, i have 10 panels that are attached to this nodes. On every panel, i have many textboxes, labels, comboboxes etc. I don't dynamically construct and dispose the items on the panels, i create the items in the designer file of the project. In that case, there is a problem. I really find it difficult to align or place items on the panel because there seems a lot of aligning lines on the screen. What should be done to make the design of the panels easy? I don't want to construct items dynamically. Do i have to do that dynamically or is there a design procedure that make this process easy?

• Movement prediction for non-shooters

  - by ShadowChaser

  I'm working on an isometric (2D) game with moderate-scale multiplayer - 20-30 players. I've had some difficulty getting a good movement prediction implementation in place. Right now, clients are authoritative for their own position. The server performs validation and broad-scale cheat detection, and I fully realize that the system will never be fully robust against cheating. However, the performance and implementation tradeoffs work well for me right now. Given that I'm dealing with sprite graphics, the game has 8 defined directions rather than free movement. Whenever the player changes their direction or speed (walk, run, stop), a "true" 3D velocity is set on the entity and a packet it sent to the server with the new movement state. In addition, every 250ms additional packets are transmitted with the player's current position for state updates on the server as well as for client prediction. After the server validates the packet, it gets automatically distributed to all of the other "nearby" players. Client-side, all entities with non-zero velocity (ie/ moving entities) are tracked and updated by a rudimentary "physics" system - basically nothing more than changing the position by the velocity according to the elapsed time slice (40ms or so). What I'm struggling with is how to implement clean movement prediction. I have the nagging suspicion that I've made a design mistake somewhere. I've been over the Unreal, Half-life, and all other movement prediction/lag compensation articles I could find, but they all seam geared toward shooters: "Don't send each control change, send updates every 120ms, server is authoritative, client predicts, etc". Unfortunately, that style of design won't work well for me - there's no 3D environment so each individual state change is important. 1) Most of the samples I saw tightly couple movement prediction right into the entities themselves. For example, storing the previous state along with the current state. I'd like to avoid that and keep entities with their "current state" only. Is there a better way to handle this? 2) What should happen when the player stops? I can't interpolate to the correct position, since they might need to walk backwards or another strange direction if their position is too far ahead. 3) What should happen when entities collide? If the current player collides with something, the answer is simple - just stop the player from moving. But what happens if two entities take up the same space on the server? What if the local prediction causes a remote entity to collide with the player or another entity - do I stop them as well? If the prediction had the misfortune of sticking them in front of a wall that the player has gone around, the prediction will never be able to compensate and once the error gets to high the entity will snap to the new position.

• How to implement behavior in a component-based game architecture?

  - by ghostonline

  I am starting to implement player and enemy AI in a game, but I am confused about how to best implement this in a component-based game architecture. Say I have a following player character that can be stationary, running and swinging a sword. A player can transit to the swing sword state from both the stationary and running state, but then the swing must be completed before the player can resume standing or running around. During the swing, the player cannot walk around. As I see it, I have two implementation approaches: Create a single AI-component containing all player logic (either decoupled from the actual component or embedded as a PlayerAIComponent). I can easily how to enforce the state restrictions without creating coupling between individual components making up the player entity. However, the AI-component cannot be broken up. If I have, for example, an enemy that can only stand and walk around or only walks around and occasionally swing a sword, I have to create new AI-components. Break the behavior up in components, each identifying a specific state. I then get a StandComponent, WalkComponent and SwingComponent. To enforce the transition rules, I have to couple each component. SwingComponent must disable StandComponent and WalkComponent for the duration of the swing. When I have an enemy that only stands around, swinging a sword occasionally, I have to make sure SwingComponent only disables WalkComponent if it is present. Although this allows for better mix-and-matching components, it can lead to a maintainability nightmare as each time a dependency is added, the existing components must be updated to play nicely with the new requirements the dependency places on the character. The ideal situation would be that a designer can build new enemies/players by dragging components into a container, without having to touch a single line of engine or script code. Although I am not sure script coding can be avoided, I want to keep it as simple as possible. Summing it all up: Should I lob all AI logic into one component or break up each logic state into separate components to create entity variants more easily?

• How can I use smbclient to connect to Windows shares by hostname when a firewall is enabled?

  - by skyblue

  I can't connect to file shares on Windows computers using smbclient -L //hostname when the firewall is enabled. This occurs whether I'm using ufw (which allows outgoing traffic and replies back in with the default configuration) or iptables (where I'm allowing outgoing traffic and replies back in with iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT). However, smbclient -L //ip-address works whether the firewall is enabled or not. I also tested this against a Samba server running on Ubuntu and again smbclient -L //hostname does not work when the firewall is enabled, but smbclient -L //ip-address works whether the firewall is enabled or not. For reference, here are the iptables rules I used during testing: *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -d 224.0.0.251/32 -p udp -m udp --dport 5353 -j ACCEPT COMMIT

• Checking For Empty Enumerations

  While spelunking in some code recently I saw a method that looked something like this: public void Foo<T>(IEnumerable<T> items) { if(items == null || items.Count() == 0) { // Warn about emptiness } } This method accepts a generic enumeration and then proceeds to check if the enumeration is null or empty. Do you see the potential problem with this code? Ill give you a hint, its this line: items.Count() == 0 Whats the problem? Well that line right there has the potential...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Is PO Box on resume to get a call okay?

  - by sanksjaya

  Hello folks! Personally I've applied to quiet a handful of IT admin jobs inside my state and to the ones that are way far away. The sad part is I never miss to get an interview with the jobs in my state, but get a call once in a blue moon from jobs out of my state. Note: All the jobs are of similar nature. Recently one of my friends told me that "Applicants with local addresses are the ones that are even looked upon". How true is this? Does filtering take place at address level before qualifications? Is using a PO box on resume acceptable [one for each state like CA, TX, VA]? Any other suggestions to get calls from out of state? Thank you :) [wiki]

• SkyDrive Pro Limits

  - by Sahil Malik

  SharePoint 2010 Training: more information I’m putting this here, because I know I’m gonna forget it :) Overall size limits - On an on premises installation, there are no fixed limits on storage. You can configure it as you wish. For Office 365 (SharePoint Online), the limit is 7GB per user. Number of items (documents and folders): You can sync up to 20,000 items in your SkyDrive (personal library). You can sync up to 5,000 items from other libraries, per library. In other words, you could sync 10 libraries (for example), with each library having up to 5000 items. Third, site limits: No fixed limits. It depends on your computer's resources. Hooray! and Happy SharePointing! Read full article ....

• Why does Outlook 2010 give the message "Creating a new item from the selected items could take some time...are you sure you create a new item...?

  - by Matt

  I'm using Outlook 2010 with Exchange 2007. I am moving emails from my Deleted Items folder to a user-created folder. When I move a "low" number of messages, say a few hundred or less, the operation completes successfully. When I move a "large" number of messages (in this example it's over 800) I get the message shown in the screenshot below. If I click Yes, a new email is generated and has links to all the emails I selected in the Attachment field. When I cancel that email, not only have the messages not moved but they appear to be deleted entirely. What does the message mean and why does it get presented? Why does clicking Yes do the behavior I described above?

• How do I keep user input and rendering independent of the implementation environment?

  - by alex

  I'm writing a Tetris clone in JavaScript. I have a fair amount of experience in programming in general, but am rather new to game development. I want to separate the core game code from the code that would tie it to one environment, such as the browser. My quick thoughts led me to having the rendering and input functions external to my main game object. I could pass the current game state to the rendering method, which could render using canvas, elements, text, etc. I could also map input to certain game input events, such as move piece left, rotate piece clockwise, etc. I am having trouble designing how this should be implemented in my object. Should I pass references to functions that the main object will use to render and process user input? For example... var TetrisClone = function(renderer, inputUpdate) { this.renderer = renderer || function() {}; this.inputUpdate = input || function() {}; this.state = {}; }; TetrisClone.prototype = { update: function() { // Get user input via function passed to constructor. var inputEvents = this.inputUpdate(); // Update game state. // Render the current game state via function passed to constructor. this.renderer(this.state); } }; var renderer = function(state) { // Render blocks to browser page. } var inputEvents = {}; var charCodesToEvents = { 37: "move-piece-left" /* ... */ }; document.addEventListener("keypress", function(event) { inputEvents[event.which] = true; }); var inputUpdate = function() { var translatedEvents = [], event, translatedEvent; for (event in inputEvents) { if (inputEvents.hasOwnProperty(event)) { translatedEvent = charCodesToEvents[event]; translatedEvents.push(translatedEvent); } } inputEvents = {}; return translatedEvents; } var game = new TetrisClone(renderer, inputUpdate); Is this a good game design? How would you modify this to suit best practice in regard to making a game as platform/input independent as possible?

  I'm having trouble setting up a VPN on my VPS that's running Ubuntu 11.04. I'm been following this guide http://tipupdate.com/how-to-install-openvpn-on-ubuntu-vps/ I'm able to start the VPN, but the command it tell's me to do after I start the VPN doesn't work for me. I've tried it about 5 different way's and i'll show you what i get now. :~# iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT iptables: No chain/target/match by that name. :~# iptables -A FORWARD state --state RELATED,ESTABLISHED -j ACCEPT Bad argument `state' Try `iptables -h' or 'iptables --help' for more information.

• How to do lazy loading in a SOA fashion?

  - by sun1991

  For example, I've got a root object exposed in a SOA service, say Invoice (Invoice has line items as children). Sometimes, I need to retrieve its detail line items. I'm thinking to make it lazy loading, because it's a traffic overhead to transfer line items every time Invoice is required. But in SOA fashion, it seems unlikely. Because all it can expose are Invoice POCOs, with contain no logic. Thus I cannot attach my lazy loading logic to Invoice to instruct it to load lines items when needed.

• Collapsible menu and amount of links in a web page

  - by dstonek

  One of my pages contain three levels of a collapsible menu (JS + CSS from mycssmenu.com). There are a dozen first level items displayed to users, each one with various second level items, and finally a lot of third level items, each one containing a related link. This generates a lot of internal links (300+). Because of SEO should I change the way the collapsible menu is displayed to reduce link amount? What do you suggest? I would like to avoid users to have to open a new page just to only see what are third level items and eventually follow one of its links.

• Split up a screen into regions

  - by nexen

  My task: I want to split up a screen into 3 regions for buffs-bar (with picked items), score-info and a game-map. It doesn't matter are regions intersect with each other or not. For example: I have a screen with width=1; height=1 and the origin of coordinates (0;0) is the left bottom point. I have 3 functions: draw items, draw info, draw map. If I use it without any matrix transformations, it draws fullscreen, because it's vertex coordinates are from 0;0 to 1;1. (pseudo-code) drawItems(); drawInfo(); drawMap(); And after that I see only map onto info onto items. My goal: I have some matrixes for transformation vertexes with 0;0-1;1 coordinates to strict regions. There is only one thing, what I need to do - set matrix before drawing. So my call of drawItems-function is like: (pseudo-code) adjustViewMatrixes_andSomethingElse(items.position_of_the_region_there_it_should_be_drawn, items.sizes_of_region_to_draw); setItemsMatrix(); drawItems(); //the same function with vertex coordinates 0;0->1;1, //but it draws in other coordinates, //because I have just set the matrix for region I know only some people will understand me, so there is a picture with regions which I need to make. Every region has 0;0 - 1;1 inner coordinates.

• How to handle notifications to several partial views of the same model?

  - by Seki

  I am working on refactoring an old simulation of a Turing machine. The application uses a class that contains the state and the logic of program execution, and several panels to display the tape representation and show the state, messages, and the GUI controls (start, stop, program listing, ...). I would like to refactor it using the MVC architecture that was not used originaly: the Frame is the only way to get access to the different panels and there is also a strong coupling between the "engine" class and the GUI updates in the way of frame.displayPanel.state.setText("halted"); or frame.outputPanel.messages.append("some thing"); It looks to me that I should put the state related code into an observable model class and make the different panels observers. My problem is that the java Observable class only provides a global notification to the Observers, while I would prefer not to refresh every Observers everytime, but only when the part that specificaly observe has changed. I am thinking of implementing myself several vectors of listeners (for the state / position, for the output messages, ...) but I feel like reinventing the wheel. I though also about adding some flags that the observers could check like isNewMessageAvailable(), hasTapeMoved(), etc but it sounds also approximative design. BTW, is it ok to keep the fetch / execute loop into the model or should I move it in another place? We can think in a theorical ideal way as I am completely revamping this small application.

• Cycling through ItemStacks whlie supplying data... LOST [on hold]

  - by user3251606

  Ok so i am working on a plugin for my server that will open and inventory and when closed it will pass items to this class... object of this class is to cycle through the inventory and use a cfg file to define items and prices and then grab that info in a for loop and add it all up... heres what i have thus far... public void sell(Player p, Inventory inv) { ListIterator<ItemStack> it = inv.iterator(); double total = 0; for (ItemStack is : inv) { is = it.next(); if (is.getType() != null) { String type = is.getType().toString(); //short dur = is.getDurability(); String check = ChestSell.plugin.getConfig().getString(type); p.sendMessage("Item Type: " + type); if (check != null) { int amou = is.getAmount(); double value = ChestSell.plugin.getConfig().getDouble(type + ".price"); double tv = amou * value; p.sendMessage("Items in chest: Type " + type + " Ammount: " + amou + " Value: $" + tv); } //TODO Add return Items } } p.sendMessage("You got paid $" + total + " for your items!"); inv.clear(); }

• RPGMakerVX - Changing item_max?

  - by rackemup420

  I've been working on a game for awhile and I am developing it with RPG Maker VX. I came to a point where I needed to... I guess for lack of better explanation... Limit the key items to just 1. So I started looking through my scripts and found (in Game_Party): #-------------------------------------------------------------------------- # * Get Maximum Number of Items Possessed #-------------------------------------------------------------------------- def max_item_number(item) return 99 end and added below it: #-------------------------------------------------------------------------- # * Get Maximum Number of Key Items Possessed #-------------------------------------------------------------------------- def max_key_item_number(item) return 1 end and right below that is: #-------------------------------------------------------------------------- # * Determine if Maximum Number of Items Are Possessed #-------------------------------------------------------------------------- def item_max?(item) item_number(item) >= max_item_number(item) end So I changed the last one too: #-------------------------------------------------------------------------- # * Determine if Maximum Number of Items Are Possessed #-------------------------------------------------------------------------- def item_max?(item) if key_item? == true item_number(item) >= max_key_item_number(item) end if key_item? == false item_number(item) >= max_item_number(item) end end Now this seemed to not affect anything (that I could tell). I tested it and its still the same as before I touched anything. I am new to developing games and relatively new to scripting for them. Is this approach even close to what I want to do? Any help is greatly apprecieated!
