Or whether I should start right at the beginning with something like the dummies books or something else entirely and then work onto an iphone specific book.

Don't get a Dummies or Sams book because they are always horrible. Barnes and Noble has that 50% off coupon on Slickdeals so go there and see what books you like.

I've gone about halfway through the Big Nerd Ranch guide and it's really good. Very thorough and they cover pretty much everything you'll want to know. They assume you know C in the pre-reqs, but I haven't seen anything that would trip you up if you don't.

I have the Deitel "iPhone for Programmers" and the WROX "Beginning iOS4 Application Development", but I haven't really gotten past the 3rd chapter or so yet. I also have the APress 'Beginning iPhone Game Programming' and 'Cocoa on the Mac', but haven't really gotten into those either.

The Big Nerd Ranch books don't click with me for some reason. They like to randomly scatter code around the chapter and it's hard for me to put it all together. The writing and teaching style are good though.

I'm working on my first iPhone game and have come up against a bit of a showstopper. I need a scrabble dictionary in memory to do some very fast spellchecking, hopefully checking about 100 words vs 250,000+ words in a single frame.

Stackoverflow gives a suggestion of using a form of compression (since you've only got 26 letters, no need to use a byte for each character) and cramming each of the 250k words in to a 64-bit value, ending up at 2mb.

Beginner question:

Let's say you're making a falling blocks game, using UIKit. For a 10 square by 10 square game field, would you make an array of UIImageViews, or would you just make an array of a 'block' struct/objects?

code:

UIImageView *gameGrid[10][10];

code:

struct
{
int solid, int color;
} block;

block *gameGrid[10][10];

_{(ignore the probably incorrect C syntax)}

If I used the second way, would I just use a method like drawAtPoint to draw the bitmap for the block for each cell in the gameGrid? Let's say I'd have < 20 images total, some for different colors of blocks and then maybe 'jewels' or another piece of each color.

Would I just keep the UIImageViews off screen or hidden, or what in that case?

Is there a quick blog post or guide to setting up your own buttons for a simple game? I just want 'right', 'left', 'rotate', and 'drop'.

I'm under the assumption that I can't (or shouldn't) use UIKit because I made my own view and I'm just drawing crap to that with Quartz2D, mostly just using my awesome sprite function hooked up to a timer:

code:

-(void) drawSprite:(int) spriteImage x:(int) x y:(int) y {
	CGContextRef context = UIGraphicsGetCurrentContext();
	CGContextSaveGState(context);
	
	[bug[spriteImage] drawInRect:CGRectMake(x, y, BZ_SPRITE_WIDTH, BZ_SPRITE_HEIGHT)];
	
	CGContextRestoreGState(context);
}

I was thinking I would just make 4 images (well maybe 8, one to use while the button is 'down') for each button and draw them every frame. Then just handle the touch events for my view, figure out which button is touched and do whatever from there. Would it be best to write some sort of function that returns a button ID instead of putting the same screen location detection in each function?

My Dr. Mario clone is up and running in the simulator.

I just got touch/buttons working, next up is respawning the pieces and doing the matching/elimination of pieces. I wrote this game last year using OpenGL/SDL so I've basically just been copying and pasting some badly written C code into a UIView subclass. Oh, and I used Quartz2D instead of OpenGL ES (Why? Hell if I know).

I'm going to bug an iPhone guy at work tomorrow and see if he can load it on an actual device so I can jerk off to it. This is pretty much the only iOS or MacOS thing I've done so far, unless you count examples from books.

I'm trying to draw graphics in a function other than drawRect

code:

@implementation SpriteTest

-(id)initWithCoder: (NSCoder *) coder {    
    if (self = [super initWithCoder: coder]) {
		[self gameLoop];
	}
	
	return self;
}

-(void)gameLoop {
	game.score = 0;
	
	[self loadGraphics];
	[self setupGraphics];
	
	[self initializeTimer];
}


- (void) animateGame:(NSTimer *)theTimer {
	[self setNeedsDisplay];
	[self processInput];
	[self gameLogic];
}


- (void)drawRect:(CGRect)rect {
	[self drawPlayingField];
	[self drawCharacter];
}

-(void) drawControls {
	int bOffset = SCREEN_VRES-BUTTON_HEIGHT;
	[gameButton[0] drawInRect:CGRectMake(BUTTON_WIDTH*0, bOffset, BUTTON_WIDTH, BUTTON_HEIGHT)];
	[gameButton[1] drawInRect:CGRectMake(BUTTON_WIDTH*1, bOffset, BUTTON_WIDTH, BUTTON_HEIGHT)];
	[gameButton[2] drawInRect:CGRectMake(BUTTON_WIDTH*3, bOffset, BUTTON_WIDTH, BUTTON_HEIGHT)];
	[gameButton[3] drawInRect:CGRectMake(BUTTON_WIDTH*4, bOffset, BUTTON_WIDTH, BUTTON_HEIGHT)];
}

The drawControls stuff works, how would I make the drawPlayingfield work in another function? It either doesn't draw or I get an error. I've tried [self drawPlayingField], but I'm thinking I'm just calling it in the wrong way.

Gordon Cole posted:

drawPlayingField isn't in the code you posted, so we can't see what it's doing.

It's basically this:

code:

[gameTile[0] drawInRect:CGRectMake(TILE_WIDTH*0, tileOffset, TILE_WIDTH, TILE_HEIGHT)];

Basically a loop that draws a bunch of background tiles.

I also have something like 'drawItems' that draws the game objects. Those are all UIImages, just like the gameButtons. When I refer to something like: [this drawWhatever] does it not work because 'this' has to be a function with a CGrect passed to it or something?

What I'm trying to accomplish is I have my game (say Tetris) running and it works okay. But when you complete a line, I want to do an animation where the rest of the pieces 'drop down', so what I did is put something in the method that 'drops' the pieces after you've completed a line(s) that moves the objects down, redraws, pauses, then moves them down another row, redraws, pauses, etc until the pieces 'land'. But no re-draw occurs.It just pauses x times and then the pieces are magically moved all the way down when that loop ends, and the 'animateGame' starts back up.

Ender.uNF posted:

You can't do it that way. When you draw outside the context of the normal draw loop, it won't get displayed. That's the reason for calling setNeedsDisplay - to let iOS know that it needs to update part of the screen (it caches the render results to improve performance and make some of the CoreAnimation effects work).

Typically in a game you separate out the concerns of drawing vs game state. For example, just do the calculation to see how many lines need to go away then kick off an animation that will remove the lines and let the logic code path continue. In your drawing code, after every x amount of time you can remove another line and move things down, adjusting the animation object as you go. When the animation is finished the draw code can remove it from the queue.

This is just one approach... There are many other possibilities. If you stay with your current design the performance will be limited but it might not matter for a tetris game, in which case using setNeedsDisplay (after every visible change) might suffice.

I realize that, but I thought I put [self setNeedsDisplay] in that other loop and it either didn't re-draw, or crashed. The code is at home or I'd check for sure.

I guess I might as well link that animation to the main timer, since as the game goes faster I'm going to want the leftover pieces to drop faster as well.

Ender.uNF posted:

Hmm.. if you are calling setNeedsDisplay at the end of your main timer it shouldn't cause a crash but there are plenty of ways to shoot yourself in the foot. Do you remember what the crash was?

If I put [self setNeedsDisplay] in the loop (not the game loop but the 'drop loose pieces loop', it never updates the screen.

If I put [self drawPlayingField] it writes this to the console:

Tue May 17 21:57:19 Rocket.local SpriteTest[431] <Error>: CGContextSaveGState: invalid context 0x0
Tue May 17 21:57:19 Rocket.local SpriteTest[431] <Error>: CGContextSaveGState: invalid context 0x0
Tue May 17 21:57:19 Rocket.local SpriteTest[431] <Error>: CGContextSetBlendMode: invalid context 0x0
Tue May 17 21:57:19 Rocket.local SpriteTest[431] <Error>: CGContextSetAlpha: invalid context 0x0
Tue May 17 21:57:19 Rocket.local SpriteTest[431] <Error>: CGContextTranslateCTM: invalid context 0x0

code:

-(void) drawSprite:(int) spriteImage
				 x:(int) x
				 y:(int) y {

	CGContextRef context = UIGraphicsGetCurrentContext();
	CGContextSaveGState(context);
	
	[tile[spriteImage] drawInRect:CGRectMake(x, y, SPRITE_WIDTH, SPRITE_HEIGHT)];
	
	CGContextRestoreGState(context);
}

So basically I'm not getting the context because it's not available where I'm calling it from.

drawPlayingField is basically a loop that calls drawSprite a bunch of times. It's like if I call drawSprite from anywhere except a function that I call from drawRect, it has those context errors. Could I store the context in a global variable or is it guaranteed not to stay the same or something?

Ender.uNF posted:

You can create your own bitmap context (matching your view's dimensions and scale) and draw to that, then in drawRect blit that to the screen (which is just another form of deferred rendering). Apple's stated requirements are to update your state, set needs display, then defer the actual drawing to drawRect.

I'll just make an off-screen buffer and draw to that.

Anyone have ideas (or even have this problem) on preventing peoples fingers from getting 'lost' on the touch screen in games?

A lot of games set the iPhone up like a video game controller, arrows on the left bottom corner and buttons on the right. But what happens to me is that since I'm not touching an actual button, my thumb will wander from say 'left' to 'right' or from 'jump' to 'shoot'. Or off the touch screen area entirely. Very frustrating.

I have two beginning Mac programming books, but neither of them cover dragging a file onto an app (the actual app, not the dock icon). I'm trying to do something where you could drag a URL from a browser's address bar onto a UIView of some sort (or a link, like if you dragged a torrent URL into a Torrent client, and it started downloading it automatically).

Where should I start?

How would you accomplish a custom view (or whatever it would be called) like the 'downloads' window in Firefox?

Also, what is a good book to pick up for iOS development itself? There's one I saw by the same publisher which has a new edition coming out next month, but if anyone has any suggestions it'd be appreciated.

Most of the beginning books are basically "Here's how you make a button", "Here's how you make a browser window", "Here's how you tell if the device is being tilted". And nothing to tie it all together or actually create anything useful.

The Big Nerd Ranch book is a good one to start with, they at least ask you questions about what you just learned and prod you a little to investigate stuff in your own.

Those would even be fine. I was thinking of making a row of gradient buttons, then altering their properties (mainly width and if the border is visible) based on which one is 'active'. Like this:

Then when I click on a 'tab', I just make the TextView that it's linked to visible (one tab and one text view for each IRC channel).

Another problem with C is that to do anything useful it's very specific on what libraries and tools you use to build it, so a good book is hard to find. Those two books won't teach you anything Mac-specific (well, the Obj-C one will) but they will do everything ON a Mac, which is a big help for a beginner.

I don't care how many people I probably infected with COVID-19 while refusing to wear a mask, my comfort is far more important than the health and safety of everyone around me!

When I create a simple Cocoa Application project, Xcode makes an 'AppDelegate.h/.m' and I put all the example code from a book in that code.

I have an older book (Cocoa Programming with Mac OS X, focusing on 10.2?) and in that version of Xcode you must have had to make the delegate classes by hand or something. Anyway, is there a way I can connect outlets to SomeOtherClass.m? Do I have to let my program know I want to access methods in those other classes, so I can get the 'blue cube' for that class to appear so I can connect Outlets to my nib?

I have newer books I just was curious to the answer to this question. I like this book (and am waiting for the new edition to come out), most of the stuff is still useful, it's just the initial setup and wiring up of the apps that gets weird.

Any recommendations for a next step? I want to buy another book. Online material is fine for supplementation but I like something physical. I was thinking this: http://www.amazon.com/iOS-Developers-Cookbook-Essential-Programmers/dp/0321832078/ref=sr_1_3?ie=UTF8&qid=1330007758&sr=8-3

Anything better?

That's not a terrible book. It's a 'cookbook' so instead of explaining here's how you do this, blah blah, it just shows you with a real example.

Is there any legitimate reason for Apple to charge $99 for EACH developer program (Mac and iOS)? Accounting? Pure evilness?

I know the only thing the $99 really gets me on the Mac side is the Mac App store but c'mon.

Stupid Objective-C question, but I'm having trouble on when to make a new object and stuff like that.

Should I do it for everything I can?

Only one object per .m file, right?

Can I make a C-style struct that contains NSObjects or is that just a bad idea?

If I were to do an object called Albums, I'd put that in Album.m and then do something like:

code:

@interface Album : NSObject {
  NSString *name;
  NSArray *songTitles
  NSNumber *price;
  NSImage *albumArt;
}

Or should these be defined some other way?

All the C++ I did was 'C using iostreams' so I'm never worked a lot with objects.

Forgive me for what may be an stupid question.

I've got a few years experience writing mobile apps (mainly Symbian) and about 6 months ago I started learning iOS development for work, and have now made a couple of business-y iPad apps. I've had an idea for a game I want to make in my free time, but having never made a game before I'm not really sure how to start.

My idea's for a game similar to Bejewelled (yeah, we need another one of those) so luckily it takes physics engines/complex input/3D rendering out of the equation. I was also going for a very minimal graphic design, similar to Async Corp with (probably) manually drawn objects rather than image textures which would usually be managed by a game engine.

Given these factors, and my inexperience with any game engines, how would you approach developing this? I see I have 3 options:

Man up and learn how one of these engines works, probably cocos2d (unless there are any other suggestions?)

Create my UI with lots of custom UIViews, one for each 'block' in the puzzle plus others for the other UI elements, and manipulate these as the game is played

Create one big custom UIView that does all the drawing for the whole game grid (I think this is a bad option)

Obviously these last 2 options lock me into UIKit and would make porting it to any other platforms far more tricky further down the line. At the moment I don't have any plans for this, but I do have an Android tablet (and know java, though nothing Android specific), so it would be neat if there was an engine I could use with zero modification (aside from the framework requirements) on both that and my iPhone.

Am I an idiot for even considering just using UIViews for this, or is it reasonable given I won't require most of the things I'd expect a game engine provides you with? As it's the method I know off the bat it may be easier for prototyping and just seeing how my idea plays out, and basic UIKit animations should cover the style I'm going for.

You could just have at it with OpenGL.

Or, make your own simple game engine:

Contrary to the title, it's not a 'beginner' book.

Xcode is such a crash-happy piece of poo poo :argh:

Is there an easy way to enable all the warnings in a '-Wall' kind of way using Xcode 4?
