I would like to thank everyone who has contributed to cocos2d-iphone. Without such a great framework and community to support it I wouldn't have the opportunity to write this book.

I want to make a 2D game with advanced graphics and physics like Cut the Rope and Angry birds. I've been working with Cocos2D but have not been able to achieve this. All the Cocos2D tutorials and apps I've found don't really teach the advanced stuff. Could someone please help me, with advice, tutorials or anything that will help me develop high quality Cocos2D games.

I was taking a look at ray' s tiny wings remake tutorial. Upon running it I noticed that the seal seems to stick to the ground (move rather slowly) before taking off (kind of like when a rock is released from a sling shot). I thought it was odd since the friction is set so low. I even set it to 0, and the same result. Does anyone know why this is?

Hi all, I just want to preface this with me stating that I'm very very new to programming as well as cocos2d and box2d. I've spend a few weeks doing nothing but research in regards to learning objective-c as well as cocos2d and I have downloaded and read tons of tutorials on building simple games just to get myself used to everything. I've been making some pretty good headway with my game (surprisingly to me) and I've run into a snag the past couple of days regarding the gravity in my game. As stated, I'm working on a very basic game which has a player character and blocks. Basically, a 50 pixel wide block will randomly spawn from somewhere off screen and move from the bottom of the screen to the top and off screen. This goes on forever with a new block randomly spawning every second. That's all fine and good. Now I'm working on the physics of the game because I need some collision so that my character can stand on the blocks and then fall off onto the next platform. When I implement box2d to create bodies for my characters, my player works just fine and has defined properties and moves around no problem at all. When I try to define a body for my blocks, it causes all sorts of problems with the gravity in the game. Essentially, the blocks stop randomly spawning only to spawn from one spot right on top of each other and then the game crashes. When I remove any definitions to the blocks, everything goes back to normal, no problem. This leads me to believe that the gravity in the world which pulls the player down is affecting the blocks. My question is, how would I go about creating a gravity that's specific only to the randomly spawning blocks so they can continue moving upwards on their own without affecting the players gravity pulling the player down? Again, I'm very new to this whole process and I've spend 2 days searching for help online through these forums as well as other websites. If this would be easier to do in Chipmunk, I'm game, but again I was having difficulty getting that to work as well. Thanks for any help/input that any of you may have.

My understanding is that when attempting to pause a game using cocos2d + spacemanager, the following lines would suffice..

[[CCDirector sharedDirector] pause];
[smgr stop];

These work well to pause the game, but on resume button being clicked I use the following lines and my app freezes..

[[CCDirector sharedDirector] resume];
[smgr start];

I am not sure why this is happening :(. Any help would be appreciated, thanks in advance!

Hello everyone, i have nearly 30 bodies in my box2d world and it lags as hell, is there any way of optimizing this?

Regards, Vadimka.

Hi,

many of you might already know me from TexturePacker - now I have a new high quality tool for you:

PhysicsEditor

Stop copy and paste!
Stop worrying about ccw or cw!
Stop worrying about convex or not.

Features:

• Automated shape tracing(!!!)
• Automated handling of convex polygons(!!!)
• Automated handling of polygon oriantation(!!!)
• Anchorpoint editor(!!!)
• Support for Box2D and Chipmunk
• plilst files for cocos2d
• box2d loader code included
• Demo

The main advantage is that you can use the exporters already shipped with PhysicsEditor or simply create your own! A flexible template engine lets you export what ever text format you need.

The download includes a fully working demo.

How to use it in your code? Forget about copy and pasting vertex lists!

This is for box2d users:

Load the plist file

[[GB2ShapeCache sharedShapeCache]   addShapesWithFile:@"shapedefs.plist"];

Add the polygons to a shape

[[GB2ShapeCache sharedShapeCache]  addFixturesToBody:body
                                   forShapeName:@"shapename"];

Set the anchor point:

[sprite setAnchorPoint:[[GB2ShapeCache sharedShapeCache]
    anchorPointForShape:@"shapename"]];

Done!

Since I am not so familiar with chipmunk I could use some help in setting up a loader in the best way for it.

Cheers
Andreas

Hey
I've developed a very simple 2D-Skijumping game. It has also a wind simulation included (I think it's the only Skijumping game on the App Store that has this) which is implemented with the Box2D physics engine.

This first release includes six different hills to play and more there will be more in the future.
Till November 1st it will be available for free on the App Store: Link

Special thanks to the developers of cocos2d and the great community!

Hi all!!!
Can anyone help me with realising hero flyint through platform and than saying on the it's top.
I've managed the collision.
My fail is cheking function:

if ((spriteA == _hero && spriteB.tag == GROUND) ||
(spriteB == _hero && spriteA.tag == GROUND))
{

if (_heroBody->GetLinearVelocity().y < 0) {
_heroBody->SetLinearVelocity(b2Vec2(0,0.99));

}
Hero just shaking all the time....What am I doing wrong???Please explain in words or code.Thank you all!!!

Critter Chaos - Goo Flinging Fun

http://www.youtube.com/watch?v=kDhLY-T1UjY

This was the first game I made using Cocos2D. We used Cocos2D mostly for scene management and texture loading, as I found it easier to write my own openGL for things like the gears and background machine wall.

The physics engine is Box2D, and the goo is just a mess of small b2CircleShape bodies and b2DistanceJoints.

I haven’t been posting in the forums much, as I was still new to the library, but now that the game is out and I have a little more experience under my belt, hopefully I can be more active.

Anyway, let me know what you think! Download and rate it if you like it!

Hello,

Im working on a game that will be in some parts similar to Squids (moving character). I have an object (2D, top-down) that moves like character in Squids - you pull a "slingshot" from object (like Angry birds), while slighshot i pulled you can rotate the character. Is anybody doing something like that, can you please send me some code? Im using Cocos2D and Box2D.

Thanks!

hi!
We are dragging an object with touch, but when touchs-ended we want the object to become static (not moving at all)
How can We do this?
We have been trying this the whole day. Please help us out

Up is down and down is up
mix your hands and don't give up.
If you are green watch out! Don't fall!
If you're blue just touch the floor.
Red and scary always right,
yellow and left would be all right.
Have some fun breaking the Law
lead your monsters to the door!

Our friends are 4 monsters!. Each one with its own law of gravity.

The blue monster falls downwards
The green monster falls upwards
The red monster falls to the right
The yellow monster falls to the left

Opposite movements are not allowed

Finish a level before night falls!

Lead all monsters to the doors of the same color in order to finish the levels.

Warning: ALL levels can be solved!

Enjoy freeing the monsters in every level!

Have fun!

Hi, my new cocos2d powered iphone game 'Flick the Frog' is available on the app store now (paid and lite versions available).
The game is an addictive, physics based action puzzle leap em up - 'flick' the frog over the 64 levels, jumping on lilypads, water sprinklers and ducks to collect as many waterlilies in as few moves as possible and gain up to 3 stars per level. Uses box2d and cocos2d, really enjoyed using the framework to make this, well done to Riq and co. for such an awesome engine. Thanks for checking it out!

Flightless has just released its third title and first iPad game, 'AnimalBlocks', to the App Store. Following the launch of our first game 'Top Dog: Farmyard Adventures' (http://www.cocos2d-iphone.org/forum/topic/5791) and app 'What Cocktail?' (http://www.cocos2d-iphone.org/forum/topic/11489) we wanted to make something fun for the iPad. AnimalBlocks is a casual, fun spelling app for kids.

Thanks again to Riq, Steve and the other cocos contributors, and to Robert from Zwopple. Here are some details;

AnimalBlocks (US$1.99, Rated 4+)

Introduction:
AnimalBlocks is a casual, fun spelling app for kids. Drag blocks into place to spell words correctly from the AnimalBlocks dictionary. The dictionary contains nearly one thousand common words, including sight words, colours, fruit & vegetables, animals and much more!

AnimalBlocks features two sets of letter blocks: one wooden set in lowercase for legibility, and another illustrated animal set for fun. There is also a selection of custom backgrounds, including a beautifully illustrated set of animals by award-winning illustrator Ali Teo.

The screen is a true multi-touch surface - great for collaborating with many hands!

Why developers will find it interesting:
AnimalBlocks looks fairly harmless but there's a lot of work under the hood to make things work sweetly and intuitively. It supports all 11 iPad touches simultaneously within the interface and Box2D physics world, and uses a fixed-timestep physics implementation to keep the simulation running smoothly. The touches/interaction can be any combination of touches on blocks or fingers just sweeping over the table. The interface also supports any iPad orientation and the sound effects pan correctly depending on the orientation as well. There's also some settings to enable the user to change the friction and magnetism of the blocks, amongst other things.

Why users will find it interesting:
AnimalBlocks is beautifully designed and illustrated, intuitive to use and fun to play. It contains about a thousand words, supporting US and UK English dictionaries. It's a casual, fun game for kids, but has some grown up design sensibilities.

Is it possible to create walls with all the non empty tiles from the layer of a TMX map? I'd like to create levels for a game using Tiled. I could then add other bodies manually by placing them at a specific tile.

I'd like to create a static box2d body that covers a layer called "walls" in the map.

Thanks

Hi,

I am using LevelSVG and have followed the instructions of taking a png of the TMX tilemap and placing it at 0,0 in InkScape, so I can trace the physics world around it.

This is working great, but what I would like to do is detect whether certain types of collisions are happening in certain tiles with specific properties. For example, if a collision with a bullet happens in a tile with a property of "isStalectite" I can place some particle effects and some crumbling physics bodies at that tile location.

Also, I would like to parse the tilemap for tiles with a property set, such as "isRockSpawner" and then periodically create physics objects at that position. But I am not sure how to swap between tile positions and physics co-ordinates.

I am also not sure how the instructions to position a bitmap in LevelSVG at (0,0) in Inkscape works...unless TMX tilemaps are created with an anchor at the bottom left (0,0), rather than in the centre...

Any advice appreciated.

Regards

i

Hello all, been a while.

Having an unfortunate issue I can't seem to combat - it's an inconsistent problem. After making a simple shape removal call, if there are resting shapes above that which was removed, shapes that are stacked will not react to the removal. They will stay motionless and dormant.

My hunch is that it has something to do with sleeping bodies, but I can't be certain. Not much to really trace back on.

Does anyone have any ideas? Thank you in advance for your help, I appreciate it greatly and will award cookies to my helpers.

Kind regards,
Mster50

Developer comments
This is actually my first game for iPhone, and my fifth game I created on my own.
I originally created flash games and done some stuff at several professional game studios. Currently I work as a mobile developer at a mobile and web development company.

Toystackers used to be a flash game which I created in Flash and was sold last year to a sponsor.
Many things I didn't like about the design and mechanics of the game.
So I decided to do a remake for the iPhone. Interesting about this version of Toystackers is that I delegate some of Apple's UIKit to create a better GUI.
For example I delegated the touch events of the UIScrollview to create a bouncing theme selection menu.

Other stuff that the game does is that some of the objects that you place are actually rag-dolls. I created an editor in Adobe Air to properly create vertexes for each rag-doll. After that I manually created the joints in static C++. All of the objects that contain physics are statically generated using a Factory Pattern in C++ using Box2d.

The art work I have drawn by hand using a Wacom Bamboo, Pixelmator and Adobe Flash

Other things added in Toystackers: Sharekit (only Twitter), Google analytics (I use this to track if the levels are too difficult).

Credits

• Cocos2d people for created a nice framework, which saved time (normally I would create my own game engine)
• Box2d people for the physics engine

If you played the game, please leave some feedback. If you liked the game please leave a review at the App Store.

Hey guys,
I'm new to iPhone Game development but developed plenty of java and flash games in the past.
Few quick questions I'd appreciate greatly if anyone can provide feedback:

1: I've only ever used png sequences for characters - anyone have suggestions on how to make a character who's sprites reacts to physics? Any good visual programs to use? At the moment I draw and animate my character in Flash and export into png sequences and code in each action. Not the best for what my target is.
2: I've installed cocos2d-iphone - Should I maybe just use cocos2d-x ? Read the home page about it being the same stuff just able to export to android. any suggestions?

Thanks for any feedback! Looking forward to working with cocos2d.

Hi,

I'm trying to implement a replay system in my current wip game which will allow to the user to view his/hers best run on each level. I'm using chipmunk for the physics with a fixed time step.
I figured out that I have to save the position of the player at each frame and then when I want to play a replay just load and set the position of the player at each frame in the update method.
The problem starts here since the above method works but not always. Sometimes it happens that the player movement on the replay is slight different then it should be. The time between start and goal is sometimes different then it should be and sometimes even the player doesn't touch the goal point which doesn't end the replay. I even tried to save the velocity of the player instead the position but still the result are the same.

So my question is how to properly save and load replays of a scene using a physics engine? Should I save velocity or position or maybe something different? Is an NSMutableArray a good container to store each frame? I want to have the replay always the same as the player played. It would nice if someone with experience would help me or point me in the right direction.

Hi there

Im making a proof of concept app which is creates a maze from an Image file.

So i load in the Image, search for the walls (using a grid search)
Load the walls and their locations into an Array.
Next i iterate through the Array and place the walls in the correct locations
(Each grid is 13x13 so each wall has a length of 13)

Now the issue im having is a Scaling issue using a PTM_RATIO of 32.0f, my generated maze is slightly bigger then my Maze I've drawn up.

Length of each wall is 0.4062f in the box2D "World"

Box2d Length = 13 / 32.0f;
Box2d Length == 0.4062f;
Pixel Length = Box2d Length * 32.0f;
Pixel Length = 12.9984f

I've narrowed this down to PTM_RATIO being the cause, my reason for thinking so is that when i changed it to 1024 (width of iPad in landscape) it lines up almost perfectly
Box2d Length = 13 / 1024.0f;
Box2d Length == 0.01269f;
Pixel Length = Box2d Length * 32.0f;
Pixel Length = 12.99999*f

.....but it broke the physics something horrible.

The reason this is important is i want to hide the Box2D objects so that the player can hit the "walls" in the picture. I dont want to create individual CCSprites for each wall, this is a memory overhead i want to avoid.

So does anyone have any idea how i can "scale down" the maze so it lines up with the picture I've drawn up.

Hi All,

I need to create a game which is similar to Paper Toss.
Can somebody guide me from where i should start?

Do i need to use Box2D or Chipmunk for that? Or it can be achieved with Cocos2D only?
The main things i would like to know is:
1. How the FLICK of the ball will happen?
2. Predict and Drawing travel path of ball, which will be arc.

Hope you guys will help me.. thanks in advance.

Hello everybody!

I'm not an iphone developer, more an android guy (since I don't own anything to develop on a mac for now). However, I recently built a desktop tool which aim is to help developers to easily create complex physics bodies for their games, and I think that it can interest everyone.

It features many useful things, like a customizable visual grid, a built-in real-time collision tester, different polygonization algorithms, help messages everywhere, etc.

Since I don't own anything to develop for iphone currently, I couldn't write a loader implementation for cocos2d. However, the output format is documented at the bottom of the project page, and an implementation is present for the android library libgdx. It should be a breeze to port it to cocos2d.

Note1: if someone makes a working loader, I would love to include it in the project. That would be an awesome addition. Thanks :)

Note2: of course, I called it Box2D Editor, but it should be useful for Chipmunk and others as well.

The project is free and open-source. Suggestions are more than welcome of course ;-)

Hello!
I'm here to get some opinions on using cocos2d as a small physics function.
I've spent using objective c for a bit of time and now hooked into it.
Also, Cocos2d made it even more fascinating and fun!
However, when I am creating my game, I found I need to add some physic functions to my game.
Well, the ones i'm thinking about is not very hard ones, so i was thinking, is it ok to use cocos2d as a small physics function?
I've heard about Box2d and Chipmunk, but they are written in C and C++, which I'm not really into (even though i did a bit of C#).

So my question is, is it still effective to use a normal Cocos2d Engine as a small physics tool?
Thanks.

Game center is amazing and I would really like to learn how to implement it inside cocos2d. I have seen ray's tutorial on it, and I sort of understand the concept. However, I don't care as much for the leaderboards/achievements as I do for the random multiplayer and the assignment of a player. See I would like to know how you can create something like a map (CCLayer) that all the players can play in. Moreover, I would like to figure out if there is a way to attach a player to lets say a ccsprite, and have a player see the map with the view of only his CCSprite, so the camera is set only on the ccsprite. Pretty much each player has his own sprite or character and can only view the world from his own character's view (third person). And also I would like to know if the layer can incorporate the Box2d physics engine so each player would essential be playing in a b2World and they would all be inside the same map. Also, I would like to know how one can make teams...it sort of hints at the possibility in the apple documentation but doesn't really explain.

Thanks for any suggestions!!

Also, if its possible please try to provide source code or a good website I can go to and learn about this. I have seen ray's tutorial and it didnt really cover this. Also, apple's documentation is great and I will probably use it to gain a deeper understanding of Game Center, but I really want to know how you can incorporate SPECIFIC cocos2d data inside Game Center because that would make things soooooo much easier!!
