rope Published by patrickC on October 29, 2010 in box2d and

cocos2d. 9 Comments Introduction

In this brief article we'll be taking a look at an efficient way

of creating ropes in our cocos2d games that use box2d, starting

from a cocos2s + box2d template project.

We will be using box2d's latest addition, the b2RopeJoint to

constrict two bodies with a rope joint (a maximum distance joint,

one might also call it), so as always big thanks to Erin Catto for

all his hard work on box2d.

We will also be using a small set of classes I wrote, VRope, that

use Verlet integration to calculate the points of the rope, using a

CCSpriteBatchNode to visually draw the rope in our game.

Click for video

It's worth mentioning that using Box2D isn't strictly necessary,

you could still use the VRope class to draw a rope between two

given points in other scenarios (for example using Chipmunk, your

own physics system, or simply updating the two points manually) and

have it react under gravity. With that in mind, the class also has

some helper methods to use it with CGPoints only.

(somethingWithPoints methods)

Setting up the project

First things first, make sure you have the latest version of

Cocos2D and create a new project with the / /

code.google.com/p/box2d/source/checkout

To update Box2D in your current project:

From within XCode, delete the Box2D folder group from the From

Finder, go to your project's folder and delete the Box2D folder

Copy over the latest version of Box2D back into your project's

folder (make sure you only copy the most deep rooted Back to

XCode, Project -> Add to Project,sport watches,

select the Box2D folder, make sure create groups (not folder

reference) is selected, Add

This should give you a working Cocos2D project, updated with the

latest Box2D source that has the b2RopeJoint ready to use.

If you're not running the latest version of cocos2d (0.99.5-rc0)

but still want to use VRope, you'll need to rename

CCSpriteBatchNode back to CCSpriteSheet, the rest should work as

is.

Using b2RopeJoint

Using the new b2RopeJoint is very easy, it's similar to the

b2DistanceJoint, but unlike other joints it doesn't have an

Initialize method.

/ / define rope joint, params: two b2bodies, two local anchor

points, length of rope b2RopeJointDef jd; jd.bodyA = body1; / /

define bodies jd.bodyB = body2; jd.localAnchorA = b2Vec2 (0,0); / /

define anchors jd.localAnchorB = b2Vec2 (0,0); jd.maxLength =

(body2-> GetPosition () - body1-> GetPosition ()). Length ();

/ / define max length of joint = current distance between bodies

world-> CreateJoint (& jd); / / create joint Verlet

Integration

Now that we know how to constrict two bodies with a rope joint,

we need to find an elegant and efficient way of drawing the rope,

drum roll,fence net

body stocking, enter screen right: Verlet integration.

The implementation you'll find below is based on a very informative

tutorial by YoAmbulante.com (for Flash) that allowed even a simple

minded person such as myself to grasp the basic concepts of Verlet

integration, so big thanks to the author of that tutorial .

The and then each of these dots are associated (grouped) by

pairs that try to keep same distance between each other as they

were when the program started.

Based on this, I decided to design 3 classes (rather than use

structs, each to his own)

VPoint - store a point's current and previous position VStick -

connect two VPoints and keep them at constant distance VRope -

keeps arrays of VPoints and VSticks, update logic,

CCSpriteBatchNode to render rope

Rather than go trough all the source code,cheap

wireless mouse, we'll be taking a look at how to implement it

into our test project.

In the main header file (VRope.h) you can find instructions on

usage, and the code is slightly commented and easy to understand,

so more advanced users could easily adapt it further to their own

needs.

Using VRope

Download the VRope class here, unzip, copy it over to your

project's folder and add it to your project from XCode.

First,ir

remote extender, you'll want to import VRope.h into

HelloWorldScene.h

# import / p>

b2Body * anchorBody; / / reference to anchor body

CCSpriteBatchNode * ropeSpriteSheet; / / sprite sheet for rope

segment NSMutableArray * vRopes; / / array to hold rope

references

Now we'll add some code to our main class,

HelloWorldScene.mm.

In the init method of HelloWorldScene, remove the creation of the

groundBody and all it's shapes and in it's place add:

/ / + + + Add anchor body b2BodyDef anchorBodyDef;

anchorBodyDef.position.Set (screenSize.width/PTM_RATIO/2,watch cell

phones, screenSize.height / PTM_RATIO * 0.7f); / / center body

on screen anchorBody = world-> CreateBody (& anchorBodyDef);

/ / + + + Add rope spritesheet to layer ropeSpriteSheet =

[CCSpriteBatchNode batchNodeWithFile: @ [Self addChild:

ropeSpriteSheet]; / / + + + Init array that will hold references to

all our ropes vRopes = [[NSMutableArray alloc] init];

In the addNewSpriteWithCoords method, add these lines at the

bottom:

/ / + + + Create box2d joint b2RopeJointDef jd; jd.bodyA =

anchorBody; / / define bodies jd.bodyB = body; jd.localAnchorA =

b2Vec2 (0,0); / / define anchors jd.localAnchorB = b2Vec2 (0,0);

jd.maxLength = (body-> GetPosition () - anchorBody->

GetPosition ()). Length (); / / define max length of joint =

current distance between bodies world-> CreateJoint (& jd);

/ / create joint / / + + + Create VRope VRope * newRope = [[VRope

alloc] init: anchorBody body2: body spriteSheet: ropeSpriteSheet];

[VRopes addObject: newRope];

In the draw method, add these lines at the bottom:

/ / + + + Update rope sprites for (uint i = 0; i

count]; i + +) {[[vRopes objectAtIndex: i] updateSprites]; }

In the tick method, add these lines at the bottom:

/ / + + + Update rope physics for (uint i = 0; i

count]; i + +) {[[vRopes objectAtIndex: i] update: dt]; }

Copy rope.png to your Resources folder and add it to your

project (rope.png can be found in the archive of the test project

below)

Build & Run! If all went well, you should have the same result

as the video at the beginning of the article.

As I mentioned at the beginning, the code is very simple and

fast (no thanks to me), so adapting it to other uses should be

pretty simple.

ready!

The Mac App Store will be similar to the App Store, but instead

of 0680d774828d967eaeb794899db913ab iOS applications, it will distribute

Mac applications.

This is big news for cocos2d users, since cocos2d already

supports Mac!!

The guidelines and other requirements for the Mac App Store are

Trainyard: Another cocos2d successful story Published by riq on

October 15, 2010 in cocos2d and games. 11 Comments

Trainyard is a very polished, well designed , orignal game.

As of today, the game is:

2nd Top Paid App in US 2nd Top Free App in US 3rd Top Grossing App

in US

What is very interesting, is that this game was developed by

just 1 person (Matt Rix) with a lot of hard work, hard work, hard

work and conviction.? I suggest reading the story behind this game.

It is very inspiring!

Trainyard: The story so far

It contains details about the whole lifecycle of a game:

CHANGELOG

Highlights:

Added support for Mac. Your cocos2d / CocosDenshion game can be

ported to Mac with minimal changes

Regarding the Mac Port

cocos2d for Mac works as excepted with the following

exceptions:

CCParticleSystemPoint is not supported. Use CCParticleSystemQuad

instead. CCTexture2d / CCLabelTTF don't support FontLabel

CCRenderTexture doesn't support It doesn't work with garbage

collection yet It doesn't support fullscreen mode yet It doesn't

support touches yet.

To port your cocos2d / CocosDenshion game to Mac, you have

to:

Modify the way you initialize / create the CCDirector and the

OpenGL view. Replace the touches and / or accelerometer events with

Mouse and / or keyboard events The rest is the same.

The cocos2d-mac.xcodeproj includes several tests that show how

to support mouse events and how to initialize the CCDirector /

OpenGL view.

The game Sapus Tongue was already ported to Mac. You can find

some details about how it was ported in this thread.

Are you porting your game to Mac? Let use know when the game is

finished!

Once editing a game you will see the iTunes info, with a link to

refresh (may take some time) and if you scroll down the page, you

will see the cocos2d categories and the cocos2d version

used,zhu

zhu pet hamsters, please try to fill all them. If you find your

game doesn't belong to any of our categories,mobile

phone chargers, please let us know.

Also note the subnavigation on the left, / p>

And if you didn't enter your username when you created the game,

no worries, you can go again to:

Autorotation in v0.99.5 templates Published by riq on August 4,

2010 in cocos2d. 8 Comments

In order to be iPad compliant, v0.99.5 will include updated

templates that support autorotation.

Basically the new templates will have 3 new files:

GameConfig.h RootViewController.m (and. H)

The? RootViewController .* files contain the code to handle the

autorotation.

And in GameConfig.h you will be able to configure how to handle

the autorotation:

No autorotation Autorotation handled by cocos2d Autorotation

handled by UIViewController (default)

No Autorotation: It means just that. The EAGLView won't be

autorotated

Autorotation by cocos2d: The EAGLView will be is not rotated).

[-]: If you are going to add UIKit objects to the EAGLView, then

you will need to rotate them manually.

Autorotation by UIViewController: The EAGLView will be rotated

by the UIViewController

[-]: The UIViewController will rotate the EAGLView and it is bit

slower than using a single glRotate () command. [+]: There is no

need to rotate any UIKit object contained by the EAGLView.

If you want to understand how to implement autorotation

manually, or if you are interested in understanding the technical

details,babydoll

dress, I suggest reading this article: < / p>

autorotation where he describes another approach. Includes sample
