Here's a short in-game video, a small trailer coming soon: <a href="http://vimeo.com/8079923" rel="nofollow">http://vimeo.com/8079923</a> (I'll also post a small post-mortem during the next days) Hopefully, it'll be released soon (we'll be sending the binary to apple in a few hours) Thanks a lot to @riq and the whole cocos2d-iphone community! best, Rolando.

It's a combination of fast paced action gaming style with the satisfaction of a sniper rifle. <img src="http://donomagames.com/Portals/0/imago_v07/gallery/SniperStrike/images/IMG_0366.PNG" /> <img src="http://donomagames.com/Portals/0/imago_v07/gallery/SniperStrike/images/IMG_0368.PNG" /> <img src="http://donomagames.com/Portals/0/imago_v07/gallery/SniperStrike/images/IMG_0374.PNG" /> <img src="http://donomagames.com/Portals/0/imago_v07/gallery/SniperStrike/images/IMG_0367.PNG" /> No video yet. OpenFeint integration with leaderboards and achievements. Dev notes: Originally using cocos 6.x, upgraded to 8.2. No spritesheets and gets about avg 40-42fps. Using 9.0 trunk, it bumps the FPS by a couple. As I'm already close to finishing this, I'll release with 8.2. Runs fairly smoothly on iPhone 3G. As per advice of Apple tech talks, I now "pre-warm" all textures and the random stuttering when text is first shown is now gone. MrLucky on "Problem giving objects different amount of lives, collisiondetection" http://www.cocos2d-iphone.org/forum/topic/4951#post-29504 Wed, 10 Mar 2010 11:51:20 +0000 MrLucky 29504@http://www.cocos2d-iphone.org/forum/ Hi, i have been searching this forum without finding a question to this problem. I am developing a game, and hopefully different enemies will have different amount of lives. With my code so far, the ones that are supposed to have 2 lives, have randomly 1 or 2 lives, the ones that should have 3 lives have randomly 1,2 or 3 lives, and i can't make it right for some reason. Please take a look at the methods and see if you can figure out what is wrong. Thx =) This is my create method: -(id) makeSpaceRockX: (cpSpace *)space x:(float) x y:(float)y hitted:(int) hitted { RockSprite = [[Sprite spriteWithFile:@"EvilMonkey2.png"] retain]; hit = hitted; cpVect verts[] = { cpv(-35,-35), cpv(-35, 35), cpv(35, 35), cpv(35,-35), }; RockBody = cpBodyNew(200.0f, INFINITY); RockBody->p = cpv(x, y); RockBody->v = cpv(0, 0); cpSpaceAddBody(space, RockBody); rockShape = cpPolyShapeNew(RockBody, 4, verts, cpvzero); rockShape->e = 0.9f; rockShape->u = 0.9f; rockShape->data = RockSprite; rockShape->collision_type = 4; cpSpaceAddShape(space, rockShape); ready = YES; return self; } The two different collision methods, one removing the bullet, and one removing the bullet and the falling object: static int bulletCollision(cpShape *a, cpShape *b, cpContact *contacts, int numContacts, cpFloat normal_coef, void *data) { GameNode *game = (GameNode*) data; [game createExplosionX:b->body->p.x + 10 y:b->body->p.y + 10]; a->body->p = cpv(-800,-800); b->body->p = cpv(-800,-800); return 0; } static int bulletCollision2(cpShape *a, cpShape *b, cpContact *contacts, int numContacts, cpFloat normal_coef, void *data) { GameNode *game = (GameNode*) data; [game createExplosionX:b->body->p.x + 10 y:b->body->p.y + 10]; b->body->p = cpv(-800,-800); return 0; } This is how i initialize them: for(int i = 0; i < 3; i++) { Rock2 *r = [[Rock2 alloc] makeSpaceRockX: space x:160 y:550 hitted:0]; [self addChild: r.getSprite]; [rocks2 addObject: r]; [r release]; } These are my collision setup, 1 is the bullet, 3 and 4 is the falling object depending on what collision to use: cpSpaceAddCollisionPairFunc(space, 4, 1, &bulletCollision2, self); cpSpaceAddCollisionPairFunc(space, 3, 1, &bulletCollision, self); And this is my update-method, that should decide how many lives each object should have: -(void) updateRocks2 { if(rock2go) { for(Rock2 *r in rocks2) { if([r getHit] == 4) { [r setHit:1]; r.getShape->collision_type = 4; } if([r getHit] == 0) { r.getShape->collision_type = 4; } if([r getHit] < 2) { r.getShape->collision_type = 4; } if([r getHit] == 2) { r.getShape->collision_type = 3; } if([r getHit] > 3) { r.getShape->collision_type = 4; [r setHit:1]; } for(Bullet *b in bullets) { if((([b getY] <= [r getY] + 40) && ([b getY] >= [r getY]-55)) && (([b getX] <= [r getX] + 25) && ([b getX] >= [r getX]-25))) { [r setHit:[r getHit]+1]; } } if([r getY] <= -600) { if(liv >0) score += 10; [r resetPosition]; [r setReady: YES]; break; } else if([r getY] <= 0) { if(liv >0) score -= 20; [r resetPosition]; [r setReady: YES]; break; } } } } bouncer80 on "[Game]SuperHero" http://www.cocos2d-iphone.org/forum/topic/2726#post-16926 Fri, 30 Oct 2009 07:22:09 +0000 bouncer80 16926@http://www.cocos2d-iphone.org/forum/ Hi all, First preview of our upcoming SuperHero action game is out.

Its a take on the classic Tic Tac Toe (naughts and crosses), played on a 4x4 grid instead of the normal 3x3. As well as the update to the size of the board I have added in the ability to shake the board to attempt to knock pieces off if they are blocking you from winning, however these is also the possibility you may knock your own pieces of during shaking the board. It currently supports 2 human players via hot swap, and human vs ai (in either hard or easy mode), although I may add new play modes depending on how well it all does. The game was completed in 1 week working on it for 1 - 2 hours per day in my spare time. I wish I had more spare time to do more, but other priorities occupy my most of my time. It was submitted today as is currently awaiting review so I will post an update as and when It is available (along with a few free codes of course ;) ). here are some screen shots (I know its not the prettiest game but I'm no artist). <img src="http://farm5.static.flickr.com/4022/4410426931_04c29eb6b4_o.jpg" /> <img src="http://farm5.static.flickr.com/4038/4410426829_729da13f4a_o.jpg" /> Par on "[Game] Fly Away Rabbit - Physics Based Block Breaking Game" http://www.cocos2d-iphone.org/forum/topic/4924#post-29398 Tue, 09 Mar 2010 14:20:36 +0000 Par 29398@http://www.cocos2d-iphone.org/forum/ Hey guys, huge thanks to cocos2d for this.

It's an arcade take on the popular card matching game "memory" (or "pairs"), complete with highscores, bonus levels and online leaderboard. the simple gameplay makes it a perfect casual game, but it becomes really difficult in the later levels and is a fun challenge for the "real" gamer as well. We have been polishing this game for a while now to stand out from all the crap in the appstore. The gameplay is very fast and smooth and we have put a lot of work in the graphics: Doppelgänger features a custom font, more than 200 handdrawn icons, 3 level sets with 50 levels each and whatnot!

The only thing I added really was a custom sprite/texture loader and manager. The physics is powered by box2d.

It should be lanuched soon. Thanks for cocos2d. I can imagine it's impossible to make this game without cocos2d. It really helps me a lot! I will post some promo codes here when the game is launched. Doodle Kart is a Doodle style top down driving game. It's funny and addictive which you'll think the game is so unique comparing with other driving games. Items/Weapons are supported during the race. You can fire a pencil/bullet to attack opponent's cars. For some special items, you can even enlarge your car to run over the other cars!

There is a download section to get new levels, once I get new ones! (working on a couple of new levels it right now) I have used cocos2d for the menus, and to render the layers and sprites, got some performance issues at some point, but so far is working fine, I think. I didn't use the isometric tiling support on last version of cocos2d as I started working on this like a year ago, can't remember, it feels a while now! I got stuck in version 0.8.2 and didn't have time to migrate to 0.9, to be honest I may need to implement from scratch the rendering routines, as implementing 2D sprites in isometric is such a pain! So I am thinking in some ray-casting or something at the pixel, lot of works I guess...

When was the last time you played with a piece of Zwirn (the German word for twine)? Centuries ago? Well, now's your chance! Zwirn is a challenging puzzle game. The first four tutorial levels show you how to play, and the remaining 21 levels will help you to become a Zwirn expert! How do you play? It's very simple! All you have to do is guide the twine with your finger, touching the dots scattered across the screen, and then connect the end of the twine to an exit. There are a number of pins available that you can place anywhere on the screen to give your Zwirn the needed shape. Does this sound too easy? Don't worry - the solutions aren't as simple as you think. __Requirements iPhone/iPod touch 2nd Generation, OS 2.2.1 or later, 5 MB __Goal & game elements - Zwirn is a solo player puzzle game. - Steer the twine with your finger. - Use the pins to give the twine the needed shape. - Connect the end of the twine to an exit. - The twine has to touch all the spots without your finger holding it. - A 'tick'-sound indicates that all black spots are touched and the twine is connected to an exit. __Controls - Pull the twine to move it. - The twine rewinds itself if you don't steer it. - The twine rewinds itself faster when you touch the entrance. - Tap a pin to pick it up. - Tap a free space to place a pin picked up. - Dragging a pin enables you to place it with more precision. The pin will move in the opposite direction. - You can either drag a pin picked up or move it directly. - Pull the twine to an exit and lift your finger to connect it. - Tap the exit to disconnect the twine . - Open or close the map with a pinch gesture. Directly jump to a level by tapping it. - Use a two-finger scroll gesture to move to a previously played adjacent level. - Control your own music by pressing the home button twice. You need to turn on the music before starting Zwirn. __Game credits Julian Kraan: Game Design, Graphics, Sound Bruno Meilick: Game Design, Programming __What makes Zwirn special? Zwirn is minimalistic in design. The game has only two game objects to play with - the twine and the pins. In spite of this, these two elements create a wide number of interactive possibilities and combinations. Zwirn is a game you want to touch and we made it as consistent and intuitive as possible. To emphasize the fact that Zwirn is a interactive toy, only the basic controls are explained and the optional ones are left to be discovered by the player. Each person can play Zwirn in his own manner. You can use the twine to sketch a solution and then use the pins to nail it down. Dragging the pins helps you to place and adjust them precisely. We took special care to allow for various solutions for each level and to equalize them in terms of difficulty. The map helps you to visualize your progress and find unsolved levels. You can jump to them in case you get stuck in the current level. We pushed the input recognition algorithm and the physics engine to the limits to make the twine feel real. But if something feels real it needs to look real too. Therefore the twine is rendered in detail and the spotlight creates a realistic shadow on both the pins and the twine. The transition between levels is smoothly animated to emphasize your progress and direction. The panning of the sound adjusts itself to the orientation of your device. You will need headphones to notice. __Backstage with the Devs :texture size: All textures but the backgrounds are grouped into three texture altas (ground, twine, pins) and each is render in one pass. This makes the display update very efficient. The background images are compress as pvrtc since when zipped this reduces the filesize by a huge amount. :transitions: We created our own transitions (slide-and-fade, fadeout-fadein) based on the examples provided. The foundation in cocos2d is very solid and you can get pretty creative with it. :physics: A physical realistic rope is very cpu time consuming to simulate. Resolving the friction around the pins multiplies the time needed. When you just spawing the objects in Box2D on a 2nd gen iPhone or iPod touch these devices are able to simulate 40 chain links and 2 pins correctly. We spend a good share of our dev time to improve this. You can see up to 120 chain links and use up to 4 pins in our game now. :controls: Getting the controls right in a game focused on physics is hard. Especially if the object manipulated exists in the real world and the player knows how it should behave. We ended up using two statemachines to track what is going on. One for what the user wants to do and one for what the twine is doing. This proved easy enough to extend and debug and good enough to get the job done. :sound: The soundscape is 2d and based on the orientation of the device. If you place a pin on the left side of a screen it will always sound like you placed it on the left side no matter the orientation of the device. You will need headphones to hear this. :spotlight: Even if all objects in Zwirn are 2D the spotlight creates a realistic shadow on the twine as well as the pins. The shadow of the twine is calculated at runtime. The texture of a pin is updated from the atlas based in its position. Even if you drag it. __News We just release a soundtrack for free on our website. It will be included in the february update, too. Sorry but we do not have any promocodes left.
