• cocoa - referencing a method on the parent

  - by Mike

  I had a method on my main view controller named "calculateThis". This method was run, obviously, as int newValue = [self calculateThis:myVariable]; when I run it from inside the view controller. Then I created a static class and I need to run this method from there. How do I reference this method from that class using just relative references, as super, superview, delegate, etc. I cannot use the class name defined on the delegate because this static class is used in several apps of mine.

• Why am I losing precision when populating an NSDecimalNumber with a double?

  - by Mike

  Here is a simple code that shows what I think is a bug when dealing with double numbers... double wtf = 36.76662445068359375000; id xxx = [NSDecimalNumber numberWithDouble: wtf]; NSString *myBug = [xxx stringValue]; NSLog(@"%.20f", wtf); NSLog(@"%@", myBug); NSLog(@"-------\n"); the terminal will show two different numbers 36.76662445068359375000 and 36.76662445068359168 Is this a bug or am I missing something? if the second number is being rounded, it is a very strange rounding btw...

• preventing a specific view from auto rotating... is that possible?

  - by Mike

  I have a view based app. Its self.view has several subviews and shouldAutorotateToInterfaceOrientation is returning YES. When I rotate the device, all views rotate as expected. Is that possible to prevent a subview from auto rotating even if the view's parent is auto rotating?

• Is it possible to resize a UITableViewCell without using UITableViewDelegate?

  - by Sam Soffes

  I want to resize my table view cells from inside the cell instead of from the UITableViewDelegate. I am resizing them based on asynchronous content, so I can't size them in the delegate. I tried setting self.frame inside the cell, but the table view was really unhappy about that. Cells were overlapping and all kinds of craziness was going on.

• Most Efficient way to deal with multiple CCSprites?

  - by nardsurfer

  I have four different types of objects within my environment(box2d), each type of object having multiple instances of itself, and would like to find the most efficient way to deal with adding and manipulating all the CCSprites. The sprites are all from different files, so would it be best to create each sprite and add it to a data structure (NSMutableArray) or would I use a CCSpriteBatchNode even though each CCSprite file is different (for each type of object)? Thanks. @interface LevelScene : CCLayer { b2World* world; GLESDebugDraw *m_debugDraw; CCSpriteBatchNode *ballBatch; CCSpriteBatchNode *blockBatch; CCSpriteBatchNode *springBatch; CCSprite *goal; } +(id) scene; // adds a new sprite at a given coordinate -(void) addNewBallWithCoords:(CGPoint)p; // loads the objects (blocks, springs, and the goal), returns the Level Object -(Level) loadLevel:(int)level; @end or using NSMutableArray objects within the Level object... @interface zLevel : zThing { NSMutableArray *springs; NSMutableArray *blocks; NSMutableArray *balls; zGoal *goal; int levelNumber; } @property(nonatomic,retain)NSMutableArray *springs; @property(nonatomic,retain)NSMutableArray *blocks; @property(nonatomic,retain)NSMutableArray *balls; @property(nonatomic,retain)zGoal *goal; @property(nonatomic,assign)int levelNumber; -(void)initWithLevel:(int)level; -(void)loadLevelThings; @end

• how to determine when two NSDates are 1 week apart?

  - by cgossain

  I'm my app I have an NSMutableArray, and each entry has an NSMutableDictionary with several Key-Value pairs. One of these pairs contains the date of the entry. For one of the functions of my app I need to determine which entries are exactly 1 week apart from each other (i.e from Sunday to Saturday) and sum the data from one of the Key-Value pairs for each day of that week. How should I go about doing this?

• iPhone Open GL ES using FBX - How do I import animations from FBX into iPhone?

  - by Dominic Tancredi

  I've been researching this extensively. We have a game that's 90% complete, using custom game logic in iPhone 4.0. We've been asked to import a 3D model and have it animate when various events happen in the game. I've put together an OpenGL view (based on Eagl and several examples), and used Blender to import the model, as well as Jeff LeMarche's script to export the .h file. After much trial, it worked, and I was able to show a rotating model (unskinned). However, the 3d artist hadn't UV unwrapped the model, so provided me a new model, this one as a Maya file, along with animation in a FBX format, a .obj file, and .tga texture unwrapped. My question is : how can I use FBX inside OpenGL ES inside iPhone to run through animations? And what's the pipeline to get this Maya file into Blender to be able to create a .h file. I've tried the obj2opengl however the model is missing normals (did it have it in the first place?) and the skin isn't applying at all (possibly a code issue, something I think I can fix). I'm trying to use Jeff LeMarche's animation tutorial but can't figure out how to get the model files into a proper .h file for use. Any advice?

• Player sprite moving slower on iPhone 4

  - by nvillec

  I just finished getting movement/jump animation for a player sprite in Xcode using Cocos2D. The basic movement algorithm is a timer that updates every 0.01 sec, changing the sprite position to (sprite.position.x + xVel, sprite.position.y + yVel). Each time a movement button is tapped, the appropriate velocity (initialized to 0) is changed to whatever speed I choose, then a stop movement button returns the velocity to 0. It's not an ideal solution but I'm very new at this and stoked to at least have that working with little help from the internet. So I may not have explained that perfectly, but it is in fact working to my satisfaction in Xcode's iPhone Simulator, however when I build it for my device and run it on my phone, the sprite's movement speed is noticeably slower than in Xcode. At first I thought it must have to do with the resolution of the iPhone 4, making the sprite's movement path twice as long, but I found that if I pull up the multitask bar, then return to the app the speed will sometimes jump back to normal. My second theory was that the code is just inefficient and is bogging the processes down, but I would see this reflected in the frame rate wouldn't I? It stays at 59-60 the whole time, and the spritesheet animation runs at the correct speed. Has anyone experienced this? Is this a really obvious issue that I'm completely missing? Any help (or tips for optimizing my approach to movement) would be much appreciated!

• Creating new games on Android and/or iPhone

  - by James Clifton

  I have a succesfull facebook poker game that is running very nicely, now some people have asked if I can port this to other platforms - mainly mobile devices (and I have been asked to make a tablet version, do I really need a seperate version?) I am currently a PHP programmer (and game designer) and I simply dont' have the time to learn Android and other languages - so I have decided to pay third parties to program them (if viable). The information I need to know is what programming language is needed for the following four devices - Android mobile phone, iPhone, iPad and tablets? Can they all run off a central sql database? If they can't then i'm not interested :( Do any of these run FLASH? Have I covered all my main bases here? For example if a person programs for a ANDROID mobile phone is that to much differant to an ANDROID tablet? They will have slightly differant graphics (because the tablet has a greater screen area might as well use it) but do they need to be started from scratch? Same goes for iPhone/iPad, do they really need to be programmed differantly if the only differance is the graphics?

  I accidentally deleted a paid iPhone app by mistake. If I want to download again, do I have to pay again? I don't have balls to pay $4.99 again just to test out.

• Uploading User Made Videos to iPhone (from Vista)

  - by Darren E.

  Once a user downloads a video created with the iPhone 3GS and then deletes it from the iPhone, that video cannot be uploaded back to the iPhone...according to Apple. The videos are not treated as Photos and are not allowed to sync to and from the iPhone freely. Has anyone discovered a program or tweek that allows one to upload video to the iPhone? Thanks.

• Design pattern for procedural terrain assets

  - by Alex

  I'm developing a procedural terrain class at the moment and am stuck on the correct design pattern. The terrain is 2D and is constructed from a series of (x,y) points. I currently have a method that just randomly adds points to an array of points to generate a random spread of points. However I need a more elaborate system for generating the terrain. The terrain will be built form a series of re-accuring terrain structures eg. a pit, jump, hill etc. Each structure will have some randomness assigned to it, each height of hill will be random, pit size will be random etc. Each terrain structure will have: A property detailing the number of points making up that structure A method for generating the points (not absolutely necessary) My current thinking is to have a class for each terrain structure, create a fixed amount of terrain elements ahead of the player, loop over these and add the corresponding points to the game. What is the best way to create these procedural terrain structures when they are ultimately just a set of functions for generating terrain elements? Is a class for each terrain element excessive? I'm developing the game for iphone so any objective-c related answers would be welcome.

• Moving 2d camera in the y direction

  - by Alex

  I'm developing a simple game for the iphone and am struggling to work out the best way for the camera to follow the main character. The following picture hightlights the three main components: There are 3 components to this: Circle - the main character Green line - terrain Black background The terrain is simply made from an array of points (approx 20 points per screen width). The terrain is moved in the x direction relative to the black background in order to keep the circle in its position shown. The distance to move the terrain is simply: movex = circle.position.x - terrain.position.x with a constant to fix the circle at some distance from the left of the screen. I am struggling to determine the best way to position the terrain in the y plane keep the focus in the character. I want to move the terrain in the y direction smoothly and not fix it to the position of the circle, so the circle can move in the y plane. If I take the same approach as the x positioning, the character is fixed at a point on the screen and the terrain moves. I could sample some terrain points either side of the character and produce an average, but in my implementation this was not smooth. I thought another approach might be to create a camera 'line' that is a smooth version of the terrain line and make the camerea follow this, but I'm not sure if this is the optimum solution. Any advice is much appreciated!

• Cocos3d lighting problem

  - by Parasithe

  I'm currently working on a cocos3d project, but I'm having some trouble with lighting and I have no idea how to solve it. I've tried everything and the lighting is always as bad in the game. The first picture is from 3ds max (the software we used for 3d) and the second is from my iphone app. http://prntscr.com/ly378 http://prntscr.com/ly2io As you can see, the lighting is really bad in the app. I manually add my spots and the ambiant light. Here is all my lighting code : _spot = [CC3Light lightWithName: @"Spot" withLightIndex: 0]; // Set the ambient scene lighting. ccColor4F ambientColor = { 0.9, 0.9, 0.9, 1 }; self.ambientLight = ambientColor; //Positioning _spot.target = [self getNodeNamed:kCharacterName]; _spot.location = cc3v( 400, 400, -600 ); // Adjust the relative ambient and diffuse lighting of the main light to // improve realisim, particularly on shadow effects. _spot.diffuseColor = CCC4FMake(0.8, 0.8, 0.8, 1.0); _spot.specularColor = CCC4FMake(0, 0, 0, 1); [_spot setAttenuationCoefficients:CC3AttenuationCoefficientsMake(0, 0, 1)]; // Another mechansim for adjusting shadow intensities is shadowIntensityFactor. // For better effect, set here to a value less than one to lighten the shadows // cast by the main light. _spot.shadowIntensityFactor = 0.75; [self addChild:_spot]; _spot2 = [CC3Light lightWithName: @"Spot2" withLightIndex: 1]; //Positioning _spot2.target = [self getNodeNamed:kCharacterName]; _spot2.location = cc3v( -550, 400, -800 ); _spot2.diffuseColor = CCC4FMake(0.8, 0.8, 0.8, 1.0); _spot2.specularColor = CCC4FMake(0, 0, 0, 1); [_spot2 setAttenuationCoefficients:CC3AttenuationCoefficientsMake(0, 0, 1)]; _spot2.shadowIntensityFactor = 0.75; [self addChild:_spot2]; I'd really appreciate if anyone would have some tip on how to fix the lighting. Maybe my spots are bad? maybe it's the material? I really have no idea. Any help would be welcomed. I already ask some help on cocos2d forums. I had some answers but I need more help.

• Is a simple iPhone app more appealing to users than a mobile website?

  - by Ryan

  My client wants to do an iPhone app because she's found that people are significantly more likely to use the iPhone app over a mobile optimized site. The iPhone app is very simple - it just displays a couple images and some text. As a programmer I'd much rather do a mobile site given the simple nature of the content. From a technical perspective I feel that it's overkill to use an iPhone app in this situation. Does it make sense to build an iPhone when a mobile site would suffice, simply because your users would much rather it be an iPhone app? Is there anyway to easily convince users that a mobile site is just as easy to use?

• Going Inside the Store

  - by David Dorf

  Location was the first "killer-tech" for smartphones, and innovators have found several ways to use it. For retail, apps exist to find nearby stores, provide coupons, and give directions to the front door. But once you enter the store, location-finding ceases to work. That's because your location is usually found by finding GPS satellites in they sky, and the store's roof blocks the signal. But it won't take technology long to solve that problem. The first problem to solve is a lack of indoor maps. Navteq and others provide very accurate maps of the outdoors, enabling navigation for cars and pedestrians. Micello is building a business creating digital maps of indoor locations like malls, convention centers, office buildings. They have over 500 live maps, including maps of IKEA stores. They claim it took them only four hours to create a map of the Stanford Shopping Center in Palo Alto with its 1.4 million square feet and 140 retail stores. And within stores, retailers are producing more accurate plan-o-grams. I'm always impressed watching demos of our space planning from AVT. It uses CAD software to allow you to walk the virtual store and see products on the shelves. The second problem is being able to determine location inside the store so it can be overlayed on the map. There are several goals for this endeavor. Your smartphone might direct you straight to particular products, it might summon a sales associate to your location for immediate assistance, and it might send you coupons based on the aisle you're viewing. Companies like Nearbuy, ZuluTime, and Skyhook are working to master indoor location using a combination of GPS signals, WiFi, and cell tower positioning to calculate a location. (Skyhook calls this WPS, as depicted in the chart.) Today they can usually hit 10 meters accuracy, but that number is improving all the time. When it gets inside 3 meters some the goals mentioned earlier will be in easy reach. I for one can't wait until the time my iPhone leads me directly to the sprinkler heads in Lowes and Home Depot.
