• Ad Service That Lets You Choose Your Ad, and Then Some [on hold]

  - by user3634450

  I'm trying to build an app for both Android and/or iOS where part of the gameplay actually involves ads as a texture. I need to be able to choose which ads I would like to use. I need to be able to be able to identify the ads (which if I can choose which ads show up in the app shouldn't be that hard). I need to be able to swap in and out new ads on what could possibly be a daily basis (and don't want to have to update the app to do it). And as if that wasn't too needy a list, I need to be able to load 50 ads from the pool of ads I deem fit, all to each and every user of the app at least every couple of days. I don't care if the ads pay, I'm not looking for clicks, but I don't want to have to make 50 fake ads every couple of days, from an "artistic" level I don't want the content to feel phony or fake, and I don't really have a way to load content to each user via some internet source (if anyone could name one that would be great). I'm not sure what kind of ad provider would like or even approve of this, in fact just what I've described might be against Google Play's or iTunes' content developer policies, but if anyone could give me any advice to steer me in the right direction it would be greatly appreciated, thank you.

• Are there any significant advantages to using a native language for mobile app development?

  - by Karl Daniel

  Forgive me if this question has already been answered but I couldn't quite find the answer I was looking for. What I wanted to know was, is there any significant advantage to using a native language when developing and deploying apps to a mobile environment? The reason I ask is for a long while now I've been using Objective-C, Apple's native language for iOS, to build my apps. However I've been wondering whether or not there is any real benefit to doing this, over using a non-native language like JavaScript and then deploying it through a service like 'Phone Gap'? I do stress 'significant' advantages as native languages are always more likely to have the upper hand when it comes to speed and access to the latest APIs. However in general I don't see using a non-native language or a service like 'Phone Gap' causing and major slow down to my apps or restricting my development. Additionally having the ability to deploy to multiple services is also very handy indeed. This is why I put the question, are there any significant advantages to using a native language for mobile app development?

• How to prevent one account from unlocking products on other devices using Apple StoreKit?

  - by reapz

  We are currently wrapping up a free-to-play game on iOS in which you can purchase non-consumable products. We have been discussing this case internally and are not quite sure what the best practices are as this is our first title. For example, if a user downloads our app, and makes some purchases. These can be restored should the app ever be deleted and reinstalled as long as the user uses the same Apple ID. What is to stop him from making a fake Apple account, purchasing items and then posting this account on the web allowing everyone to get the items for free? That is obviously a worst case situation. But a smaller case would be a user unlocking items for his friends. We do not want this to be an always online game but have considered doing a check on startup if there is internet available. If the currently logged in account doesn't own the products do we lock them again? Probably not because people may simply sign into the device with different Game Center logins at which point we don't want to constantly lock and unlock items. At some point we will be adding multiplayer at which point we can definately do a check with the currently logged in account. This is because A, they will be online when attempting multiplayer, and B, they will want to use their own account for multiplayer. Unfortunately we aren't quite ready for this yet. Has anyone tackled this issue. Are we overthinking here?

• Weird UIView transforms in Retina iPhone

  - by ggambett

  I'm having a problem I don't understand. I'm developing an OpenGL app for iOS. Because at some points I want to force the orientation of the view programatically, and Apple for whatever reason doesn't make it easy (or even possible), I'm doing it by hand. I return always NO in shouldAutoRotateToInterfaceOrientation, and when I want to change the orientation (to portrait, for example), I do something like this in the UIView: [self setTransform:CGAffineTransformMake(1, 0, 0, 1, 0, 0)]; [self setBounds:CGRectMake(0, 0, 768, 1024)]; This works fine. In order to support Retina devices, I started checking [UIScreen mainScreen].scale, and setting self.contentScaleFactor accordingly. I also modified the code above to account for the new dimensions, like this: [self setTransform:CGAffineTransformMake(1, 0, 0, 1, 0, 0)]; [self setBounds:CGRectMake(0, 0, 2*768, 2*1024)]; Same rotation, different size. The weird result with this is that I get a "screen" with the right size, but offsetted half a screen to the bottom and the left. To correct for this, I need to do the following: [self setTransform:CGAffineTransformMake(1, 0, 0, 1, 0, 0)]; [self setBounds:CGRectMake(-768, -1024, 2*768 - 768, 2*1024 - 1024)]; This works, but it's ugly, I also need to make similar corrections when I get touch coordinates, and worst of all, I don't understand what's going on or why the above "correction" works. Can anyone shed some light on this issue?

• What is the best way to store meshes or 3d models in a class

  - by Robse

  I am wondering, how I should store my mesh into memory after loading it from whatever file. I have Questions floating in my head: Should a mesh could have sub meshes or does the 3d model just store a list of meshes all on the same level Is there one material assigned to one mesh 1:1? What do I have to consider, if I want to store skeletal animations? Btw it's a OpenGL|ES2 iOS game using GLKit. I came up with some basic struct types: (But I think they are way to simple and I need to add padding or change the vector3 to vector4.) typedef union _N3DShortVector2 { struct { short x, y; }; struct { short s, t; }; short v[2]; } N3DShortVector2; typedef union _N3DShortVector3 { struct { short x, y, z; }; struct { short r, g, b; }; struct { short s, t, p; }; short v[3]; } N3DShortVector3; typedef GLKVector3 N3DFloatVector3; typedef struct _N3DMeshRecordSV3 { N3DShortVector3 v1, v2, v3; } N3DMeshRecordSV3; typedef struct _N3DMeshRecordSV3FN3ST2 { N3DShortVector3 v1, v2, v3; N3DFloatVector3 n1, n2, n3; N3DShortVector2 t1, t2, t3; } N3DMeshRecordSV3FN3ST2;

• Need ideas on how to give my levels structure

  - by akuritsu

  I am making an iOS game for a project at school. It is going to be a tiny bit like Fruit Ninja, as in it will have different things on the screen, and when you hit them, they die, and you get points. The trouble is that unlike Fruit Ninja, my game will have different types of sprites, all doing different things (moving different places, doing different things, etc). The one thing that is bad about having all of these sprites that do different things is that it is hard for them to look neat on the screen all together. I was planning on having a couple of different gamemodes: Time Trial You have 120 seconds to kill as many sprites as possible. Survival You have three lives, every time you try to hit a sprite and miss, you lose a life. ???? Whatever I think of. I am a rookie to game design in general, and I don't know the best way to make my game look good, and play well. I could have all of these sprites on the screen at the same time, or I could have them come in waves, for example 10 of sprite_a come on, and once they are killed, 10 of sprite_b come on, etc... Please give me your opinion about which one I should code. If you have any other suggestions for either a third gamemode, or a completely different way to make the levels, feel free to tell me.

• MVC design patterns

  - by insane-36

  I have an application and it does not use a very good structure. However it seems to me that I have tried to stick to mvc design pattern but a senior engineer claims that I have no design patterns and code are mesh. How I have structured the code : I have couple of nsmanagedobject model classes which represents model in my case and a reskit library which encapsulates the nsurlconnection and url request. I fetch the request from the view controller itself and then when the request get completed I create predicate and then populate it in tableview. Wherever I need custom view either I create it in nib or create in a custom subclass of UIView. I have use delegation pattern and notification to communication to view controller, views and block callback with restkit. But, the senior engineer is very new to ios. He has been doing it for 2 months now but he is a good java programmer. So, what is mvc pattern ? Is core data model not working as a model objects, view controller as controller and views. I dont seem to find any other places or any other cases to create my own model object since the most of the models are used as NSManagedObject subclass.

• colliding btRigidBody objects behave strangely when moving slowly

  - by Piku

  I'm trying to use Bullet Physics in my iOS game. The engine appears to be correctly compiled in that the demos work fine. In my game I have the player's ship and some enemy ships. They're defined as btRigidBody objects and btCollisionObjects and I'm using btSphereShapes for collision. At 'fast' speeds, collisions appear to happen sensibly - things collide and nothing goes 'weird'. If the speeds are very slow though and the player's ship touches a non-moving object the collision happens, but then the player's ship moves at incredible speed over the next few frames and appears a long distance from where it collided - completely out of proportion to the speed it was moving before impact. To move the things around I'm using setLinearVelocity() each frame, ticking the physics engine, then using getMotionState() to update the rendering code I have. Part of the issue might be I don't quite understand how to set the correct mass or what the best speeds are to use for anything. I'm mostly sticking numbers in and seeing what happens. Should I be using Bullet in this way, and are there any guidelines for deciding on the mass of objects? (am I right in assuming that in collisions heavier objects will force lighter objects to move more)

• Game with changing logic

  - by rsprat

  I'm planing to develop a puzzle like mobile game (android/ios) with a different logic for each puzzle. Say, for example one puzzle could be a Rubik's cube and another one a ball maze. Many more new puzzles will appear during the life of the game, and I want the users to be able to play those new puzzles. The standard way for managing this would be through application updates. Each time a new puzzle or bunch of puzzles appear, create a new update for the app that the user can download. However, I would like to do it in a more transparent way. When a new puzzle appears, the basic info of the puzzle would be displayed in the app menu, and the user would be able to play it by just clicking it. What comes to my mind is that the app would automatically download a .dll or .jar and inject it in the application at runtime. Is that even possible? Are there any restrictions from the OS? Is there a better way for solving it? Thanks alot

• The model to sell apps on App Store is better with a paid only version?

  - by ????

  Rob Napier, the author of iOS 5 Programming Pushing the Limits, mentioned there are several models of selling apps on the App Store: Write an app and sell it Publish a free and a full version Ad supported by third party or by iAd In App purchase Surprisingly, the author said that the most workable model is (1) in terms of sales. I would think that (2) with fairly limiting ability for the free version can bring more sales, as people without trying, might not plunge down $0.99 or $1.99 for something they haven't tried? I for one, might not have purchased Angry Birds if I didn't try their free version first. Also, I think it also depends on the situation: if the app is about alarm clock, and there are already 5 alarm clocks in App Store that are free, then your app that is $0.99 might not be that eagerly purchased. If yours is also free, and users really like it out of all the other ones, then they may think, $0.99 is nothing to get a good alarm clock, and gladly pay you the $0.99 in exchange for a full version of the alarm clock, something that they can't get with the free version. (such as the full version can let you choose a song from your Music Library for the alarm). Could (1) work only if the user definitely want it and have no substitute? How might it work the best?

  - by Lakshmi Narayanan Guptha

  I have connected my Windows live account(Microsoft account), Facebook account and Google account with Windows 8. On "People" Windows 8 app it shows as connected to Microsoft, Facebook, Google, whereas in "Messaging" app its connected only to Microsoft and Facebook. While I can chat with Facebook online contacts and messenger's, I cant find my Google online contacts only on Messaging app. Seems like Google supports only sharing of contacts and not chat as of now. Does anyone knows how to get Google chat on Windows 8 Messaging?

• C++ FBX Animation Importer Using the FBX SDK

  - by Mike Sawayda

  Does anyone have any experience using the FBX SDK to load in animations. I got the meshes loaded in correctly with all of their verts, indices, UV's, and normals. I am just now trying to get the Animations working correctly. I have looked at the FBX SDK documentation with little help.

• If You Could Cut Your Meeting Times in ½ Would You?

  - by Brian Dayton

                  I know it sounds like a big promise. And what I'm thinking about may not cut a :60 minute meeting into :30 minutes, but it could make meetings and interactions up to 2X more productive. How? Social Media for the Enterprise, Not Social Media In the Enterprise Bear with me. I'm not talking about whether or not workers should or shouldn't have access to Facebook on corporate networks. That topic has been discussed @ length. I'm also not talking about the direct benefits of Social Networking tools like Presence (the ability to see someone online and ask a question in real-time), blogs, RSS feeds or external tools like Twitter. The Un-Measurable Benefits Would you do something that you believe will have a positive effect--but can't be measured? It's impossible to quantify the effectiveness of a meeting. However, what I am talking about would be more of a byproduct of all of the social networking tools above. Here's the hypothesis: As I've gotten more and more busy with work, family, travel and kids--and the same has happened to my friends and family--I'm less and less connected. But by introducing Facebook to my life I've not only made connections with longtime friends whom I haven't spoken to in years--but I've increased the pace and quality of interactions, on and offline, with close friends who I see and speak to every week. In some cases it even enhances the connections and interactions with those I see or speak to every day. The same holds true in an organization. Especially a larger one with highly matrixed organizational structures. You work with people on a project, new people come in with each different project and a disproportionate amount of time is spent getting oriented and staying current. Going back to the initial value proposition--making meetings shorter/more effective--a large amount of time is spent: -          At Project Kick-off: Meeting and understanding team member's histories, goals & roles -          Ongoing: Summarizing events since the last meeting or update email In my personal, Facebook life today I know that: -          My best friend from college - has been stranded in India for 5 days because of the volcano in Iceland and is now only 250 miles from home -          One of my co-workers started conference calls at 6:30 this morning -          My wife wasn't terribly pleased with my painting skills in our new bathroom (disclosure: she told me this face to face too) Strengthening Weak Links A recent article in CIO Magazine, Three Dangerous Social Media Misconceptions (Kristen Burnham, March 12, 2010) calls out the #1 misconception as follows: 1. "Face-to-face relationships are far more valuable than virtual ones." While some level of physical interaction will always add value to relationships, Gartner says that come 2020, most relationships and teams will be based on "weak links"--that is, you may not have personally met a contact, but you'll know of or may have interacted with him via social sites like Facebook, LinkedIn and Twitter. The sooner your enterprise adopts these tools, the sooner your employees will learn them, and the sooner you'll begin to cultivate these relationships-of-the-future.   I personally believe that it's not an either/or choice between face-to-face and virtual interactions. In fact, I'll be as bold as saying it doesn't matter. I can point to two extremely valuable work relationships that I've had over the past 5 years: -          I shared an office with one of them -          I met the other person, face-to-face, only once Both relationships were very productive. The dynamics were similar. The communication tactics differed immensely. What does matter is the quality, frequency and relevance of interactions. Still sound like too much? An over-promise? Stay tuned for my next post The Gap Between Facebook and LinkedIn. I'll also connect some of the dots with where Oracle Applications and technologies are headed.

• Restricting joystick within a radius of center

  - by Phil

  I'm using Unity3d iOs and am using the example joysticks that came with one of the packages. It works fine but the area the joystick moves in is a rectangle which is unintuitive for my type of game. I can figure out how to see if the distance between the center and the current point is too far but I can't figure out how to constrain it to a certain distance without interrupting the finger tracking. Here's the relevant code: using UnityEngine; using System.Collections; public class Boundary { public Vector2 min = Vector2.zero; public Vector2 max = Vector2.zero; } public class Joystick : MonoBehaviour{ static private Joystick[] joysticks; // A static collection of all joysticks static private bool enumeratedJoysticks=false; static private float tapTimeDelta = 0.3f; // Time allowed between taps public bool touchPad; // Is this a TouchPad? public Rect touchZone; public Vector2 deadZone = Vector2.zero; // Control when position is output public bool normalize = false; // Normalize output after the dead-zone? public Vector2 position; // [-1, 1] in x,y public int tapCount; // Current tap count private int lastFingerId = -1; // Finger last used for this joystick private float tapTimeWindow; // How much time there is left for a tap to occur private Vector2 fingerDownPos; private float fingerDownTime; private float firstDeltaTime = 0.5f; private GUITexture gui; // Joystick graphic private Rect defaultRect; // Default position / extents of the joystick graphic private Boundary guiBoundary = new Boundary(); // Boundary for joystick graphic public Vector2 guiTouchOffset; // Offset to apply to touch input private Vector2 guiCenter; // Center of joystick private Vector3 tmpv3; private Rect tmprect; private Color tmpclr; public float allowedDistance; public enum JoystickType { movement, rotation } public JoystickType joystickType; public void Start() { // Cache this component at startup instead of looking up every frame gui = (GUITexture) GetComponent( typeof(GUITexture) ); // Store the default rect for the gui, so we can snap back to it defaultRect = gui.pixelInset; if ( touchPad ) { // If a texture has been assigned, then use the rect ferom the gui as our touchZone if ( gui.texture ) touchZone = gui.pixelInset; } else { // This is an offset for touch input to match with the top left // corner of the GUI guiTouchOffset.x = defaultRect.width * 0.5f; guiTouchOffset.y = defaultRect.height * 0.5f; // Cache the center of the GUI, since it doesn't change guiCenter.x = defaultRect.x + guiTouchOffset.x; guiCenter.y = defaultRect.y + guiTouchOffset.y; // Let's build the GUI boundary, so we can clamp joystick movement guiBoundary.min.x = defaultRect.x - guiTouchOffset.x; guiBoundary.max.x = defaultRect.x + guiTouchOffset.x; guiBoundary.min.y = defaultRect.y - guiTouchOffset.y; guiBoundary.max.y = defaultRect.y + guiTouchOffset.y; } } public void Disable() { gameObject.active = false; enumeratedJoysticks = false; } public void ResetJoystick() { if (joystickType != JoystickType.rotation) { //Don't do anything if turret mode // Release the finger control and set the joystick back to the default position gui.pixelInset = defaultRect; lastFingerId = -1; position = Vector2.zero; fingerDownPos = Vector2.zero; if ( touchPad ){ tmpclr = gui.color; tmpclr.a = 0.025f; gui.color = tmpclr; } } else { //gui.pixelInset = defaultRect; lastFingerId = -1; position = position; fingerDownPos = fingerDownPos; if ( touchPad ){ tmpclr = gui.color; tmpclr.a = 0.025f; gui.color = tmpclr; } } } public bool IsFingerDown() { return (lastFingerId != -1); } public void LatchedFinger( int fingerId ) { // If another joystick has latched this finger, then we must release it if ( lastFingerId == fingerId ) ResetJoystick(); } public void Update() { if ( !enumeratedJoysticks ) { // Collect all joysticks in the game, so we can relay finger latching messages joysticks = (Joystick[]) FindObjectsOfType( typeof(Joystick) ); enumeratedJoysticks = true; } //CHeck if distance is over the allowed amount //Get centerPosition //Get current position //Get distance //If over, don't allow int count = iPhoneInput.touchCount; // Adjust the tap time window while it still available if ( tapTimeWindow > 0 ) tapTimeWindow -= Time.deltaTime; else tapCount = 0; if ( count == 0 ) ResetJoystick(); else { for(int i = 0;i < count; i++) { iPhoneTouch touch = iPhoneInput.GetTouch(i); Vector2 guiTouchPos = touch.position - guiTouchOffset; bool shouldLatchFinger = false; if ( touchPad ) { if ( touchZone.Contains( touch.position ) ) shouldLatchFinger = true; } else if ( gui.HitTest( touch.position ) ) { shouldLatchFinger = true; } // Latch the finger if this is a new touch if ( shouldLatchFinger && ( lastFingerId == -1 || lastFingerId != touch.fingerId ) ) { if ( touchPad ) { tmpclr = gui.color; tmpclr.a = 0.15f; gui.color = tmpclr; lastFingerId = touch.fingerId; fingerDownPos = touch.position; fingerDownTime = Time.time; } lastFingerId = touch.fingerId; // Accumulate taps if it is within the time window if ( tapTimeWindow > 0 ) { tapCount++; print("tap" + tapCount.ToString()); } else { tapCount = 1; print("tap" + tapCount.ToString()); //Tell gameobject that player has tapped turret joystick if (joystickType == JoystickType.rotation) { //TODO: Call! } tapTimeWindow = tapTimeDelta; } // Tell other joysticks we've latched this finger foreach ( Joystick j in joysticks ) { if ( j != this ) j.LatchedFinger( touch.fingerId ); } } if ( lastFingerId == touch.fingerId ) { // Override the tap count with what the iPhone SDK reports if it is greater // This is a workaround, since the iPhone SDK does not currently track taps // for multiple touches if ( touch.tapCount > tapCount ) tapCount = touch.tapCount; if ( touchPad ) { // For a touchpad, let's just set the position directly based on distance from initial touchdown position.x = Mathf.Clamp( ( touch.position.x - fingerDownPos.x ) / ( touchZone.width / 2 ), -1, 1 ); position.y = Mathf.Clamp( ( touch.position.y - fingerDownPos.y ) / ( touchZone.height / 2 ), -1, 1 ); } else { // Change the location of the joystick graphic to match where the touch is tmprect = gui.pixelInset; tmprect.x = Mathf.Clamp( guiTouchPos.x, guiBoundary.min.x, guiBoundary.max.x ); tmprect.y = Mathf.Clamp( guiTouchPos.y, guiBoundary.min.y, guiBoundary.max.y ); //Check distance float distance = Vector2.Distance(new Vector2(defaultRect.x, defaultRect.y), new Vector2(tmprect.x, tmprect.y)); float angle = Vector2.Angle(new Vector2(defaultRect.x, defaultRect.y), new Vector2(tmprect.x, tmprect.y)); if (distance < allowedDistance) { //Ok gui.pixelInset = tmprect; } else { //This is where I don't know what to do... } } if ( touch.phase == iPhoneTouchPhase.Ended || touch.phase == iPhoneTouchPhase.Canceled ) ResetJoystick(); } } } if ( !touchPad ) { // Get a value between -1 and 1 based on the joystick graphic location position.x = ( gui.pixelInset.x + guiTouchOffset.x - guiCenter.x ) / guiTouchOffset.x; position.y = ( gui.pixelInset.y + guiTouchOffset.y - guiCenter.y ) / guiTouchOffset.y; } // Adjust for dead zone float absoluteX = Mathf.Abs( position.x ); float absoluteY = Mathf.Abs( position.y ); if ( absoluteX < deadZone.x ) { // Report the joystick as being at the center if it is within the dead zone position.x = 0; } else if ( normalize ) { // Rescale the output after taking the dead zone into account position.x = Mathf.Sign( position.x ) * ( absoluteX - deadZone.x ) / ( 1 - deadZone.x ); } if ( absoluteY < deadZone.y ) { // Report the joystick as being at the center if it is within the dead zone position.y = 0; } else if ( normalize ) { // Rescale the output after taking the dead zone into account position.y = Mathf.Sign( position.y ) * ( absoluteY - deadZone.y ) / ( 1 - deadZone.y ); } } } So the later portion of the code handles the updated position of the joystick thumb. This is where I'd like it to track the finger position in a direction it still is allowed to move (like if the finger is too far up and slightly to the +X I'd like to make sure the joystick is as close in X and Y as allowed within the radius) Thanks for reading!

• SQL DB design to support user feeds (in application like facebook)

  - by Yoav

  I have a social network server with a MySql DB. I want to show the users feeds like done in Facebook. Example - UserX now Friend with userY, userX did like on postX etc. Currently I have table: C1 : UserId C2 : LogType (now friend, did like etc) C3 : ObjectId (Can be userId or postId) - set depending on the LogType. Currently to get all related logs to show to the user I do the following queries: 1. Get All user Friends userIds 2. Query all rows which C1 is in userIds (I query completed) 3. Scan the DB and see - if LogType equals DidLike, check if post's OwnerId is the userId - if yes add it to logs. And so on. Obvious this is not efficient at all. I am looking for a better way. I thought I had in mind: Create a new table (in addition to the Log table) C1 : UserId C2 : LogId (from Log table) C3 : UserID of the one who did the action When querying logs - look in the table and get related Logs (by LogId) from LogTable. Updating the table: Whenever user doing action that should be in the log: 1. Add the Log entry to LogTable. 2. Scan the DB and see which users are interested with the Log (Who my friends are, Who is the owner of the post) and add related entries to the new table. (must be done in BG). 3. If user UNFRIEND another user - then look in the logs for all rows where C3 == UNFRIENDED user id and delete them. Any opinions? Other suggestions?

• Designing object oriented programming

  - by Pota Onasys

  Basically, I want to make api calls using an SDK I am writing. I have the following classes: Car CarData (stores input values needed to create a car like model, make, etc) Basically to create a car I do the following: [Car carWithData: cardata onSuccess: successHandler onError: errorHandler] that basically is a factory method that creates instance of Car after making an API call request and populating the new Car class with the response and passes that instance to the successHandler. So "Car" has the above static method to create that car, but also has non-static methods to edit, delete cars (which would make edit, delete API calls to the server) So when the Car create static method passes a new car to the successHandler by doing the following: successHandler([[Car alloc] initWithDictionary: dictionary) The success handler can go ahead and use that new car to do the following: [car update: cardata] [car delete] considering the new car object now has an ID for each car that it can pass to the update and delete API calls. My questions: Do I need a cardata object to store user inputs or can I store them in the car object that would also later store the response from all of the api calls? How can I improve this model? With regards to CarData, note that there might be different inputs for the different API calls. So create function might need to know model, make, etc, but find function might need to know the number of items to find, the limit, the start id, etc.

• In facebook pictures bdon't always load properly and scrolling is very jerky

  - by peterpipe

  I'm new to Ubuntu. I've been using 12.04LTS for over a week now. For 3 days it was great but now I'm having a number of problems. I'm using an Acer Aspire one D255 it has a 250GB HDD and a 1GB Memory. My browser is Firefox. Pages freeze occasionally and I wait for over 10 minutes and have to use the computer's 'off' button. Pages crash. On facebook some pictures don't load and I have to close down and restart a couple of times. Scrolling can sometimes be very jerky. Downloading software has become a problem and I have a 'no entry' sign in the top taskbar. I've looked at this page for some help but the words used and the explanations are not helpful to someone like me who has little knowledge of this. Please - 'Ubuntu for dummies'. I'd like to continue using Ubuntu but am close to giving up.

• Real-Time Multi-User Gaming Platform

  - by Victor Engel

  I asked this question at Stack Overflow but was told it's more appropriate here, so I'm posting it again here. I'm considering developing a real-time multi-user game, and I want to gather some information about possibilities before I do some real development. I've thought about how best to ask the question, and for simplicity, the best way that occurred to me was to make an analogy to the field (or playground) game darebase. In the field game of darebase, there are two or more bases. To start, there is one team on each base. The game is a fancy game of tag. When two people meet out in the field, the person who left his base most recently timewise captures the other person. They then return to that person's base. Play continues until everyone is part of the same team. So, analogizing this to an online computer game, let's suppose there are an indefinite number of bases. When a person starts up the game, he has a team that is located at, for example, his current GPS coordinates. It could be a virtual world, but for sake of argument, let's suppose the virtual world corresponds to the player's actual GPS coordinates. The game software then consults the database to see where the closest other base is that is online, and the two teams play their game of virtual tag. Note that the user of the other base could have a different base than the one run by the current user as the closest base to him, in which case, he would be in two simultaneous battles, one with each base. When they go offline, the state of their players is saved on a server somewhere. Game logic calls for the players to have some automaton-logic of some sort, so they can fend for themselves in a limited way using basic rules, until their user goes online again. The user doesn't control the players' movements directly, but issues general directives that influence the players' movement logic. I think this analogy is good enough to frame my question. What sort of platforms are available to develop this sort of game? I've been looking at smartfoxserver, but I'm not convinced yet that it is the best option or even that it will work at all. One possibility, of course, would be to roll out my own web server, but I'd rather not do that if there is an existing service out there already that I could tap into. I will be developing for iOS devices at first. So any suggestions would be greatly appreciated. I think I need to establish the architecture first before proceeding with this project. Note that darbase is not the game I intend to implement, but, upon reflection, that might not be a bad idea either.

• Rendering Texture Quad to Screen or FBO (OpenGL ES)

  - by Usman.3D

  I need to render the texture on the iOS device's screen or a render-to-texture frame buffer object. But it does not show any texture. It's all black. (I am loading texture with image myself for testing purpose) //Load texture data UIImage *image=[UIImage imageNamed:@"textureImage.png"]; GLuint width = FRAME_WIDTH; GLuint height = FRAME_HEIGHT; //Create context void *imageData = malloc(height * width * 4); CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(imageData, width, height, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGColorSpaceRelease(colorSpace); //Prepare image CGContextClearRect(context, CGRectMake(0, 0, width, height)); CGContextDrawImage(context, CGRectMake(0, 0, width, height), image.CGImage); glGenTextures(1, &texture); glBindTexture(GL_TEXTURE_2D, texture); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, imageData); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); Simple Texture Quad drawing code mentioned here //Bind Texture, Bind render-to-texture FBO and then draw the quad const float quadPositions[] = { 1.0, 1.0, 0.0, -1.0, 1.0, 0.0, -1.0, -1.0, 0.0, -1.0, -1.0, 0.0, 1.0, -1.0, 0.0, 1.0, 1.0, 0.0 }; const float quadTexcoords[] = { 1.0, 1.0, 0.0, 1.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0, 1.0, 1.0 }; // stop using VBO glBindBuffer(GL_ARRAY_BUFFER, 0); // setup buffer offsets glVertexAttribPointer(ATTRIB_VERTEX, 3, GL_FLOAT, GL_FALSE, 3*sizeof(float), quadPositions); glVertexAttribPointer(ATTRIB_TEXCOORD0, 2, GL_FLOAT, GL_FALSE, 2*sizeof(float), quadTexcoords); // ensure the proper arrays are enabled glEnableVertexAttribArray(ATTRIB_VERTEX); glEnableVertexAttribArray(ATTRIB_TEXCOORD0); //Bind Texture and render-to-texture FBO. glBindTexture(GL_TEXTURE_2D, GLid); //Actually wanted to render it to render-to-texture FBO, but now testing directly on default FBO. //glBindFramebuffer(GL_FRAMEBUFFER, textureFBO[pixelBuffernum]); // draw glDrawArrays(GL_TRIANGLES, 0, 2*3); What am I doing wrong in this code? P.S. I'm not familiar with shaders yet, so it is difficult for me to make use of them right now.

• Strategy for avoiding duplicate object ids for data shared across devices using iCloud

  - by rmaddy

  I have a data intensive iOS app that is not using CoreData nor does it support iCloud synching (yet). All of my objects are created with unique keys. I use a simple long long initialized with the current time. Then as I need a new key I increment the value by 1. This has all worked well for a few years with the app running isolated on a single device. Now I want to add support for automatic data sync across devices using iCloud. As my app is written, there is the possibility that two objects created on two different devices could end up with the same key. I need to avoid this possibility. I'm looking for ideas for solving this issue. I have a few requirements that the solution must meet: 1) The key needs to remain a single integral data type. Converting all existing keys to a compound key or to a string or other type would affect the entire code base and likely result in more bugs than it's worth. 2) The solution can't depend on an Internet connection. A user must be able to run the app and add data even with no Internet connection. The data should still resolve properly later when the data syncs through iCloud once a connection is available. I'll accept one exception to this rule. If no other option is available, I may be open to requiring an Internet connection the first time the app's data is initialized. One idea I have been toying around with in my head is logically splitting the integer key into two parts. The high 4 or 5 bits could be used as some sort of device id while the rest represents the actual key. The fuzzy part is figuring out how to come up with non-conflicting device ids that fit in a few bits. This should be viable since I don't need to deal will millions of devices. I just need to deal with the few devices that would be shared by a given iCloud account. I'm open to suggestions. Thanks.
