It’s so cold…

hello, world.

Mother Fucker What’s In Charge or Mother Fucker Who’s In Charge.

Hi there,

I’ve been studying English. but sometimes it makes me confused…
today i want to introduce one on the great book.

the Book is “Watch your F*king language” by Steling Jhonson.

open with google books.

Engish is the standard form of communication. It’s used worldwide by people who are from different countries but need to communicate with each other.
English is also seen as the business language, as for reasons mentioned above.
We study it also for the reasons we study any language-we need to have a way to articulate the things we need and desire.

English is also used primarily on the internet-which today connects millions of people world wide.
English is used in many different countries also because curing the Colonial and Imperial Age, Britain proved to be “successful” at gaining colonies on different continents around the world.

どうして私たちは英語を学ぶ必要があるのですか？

英語はコミュニケーションの基準となるものです。世界中の異なる国から来た人に使われています、お互いのコミュニケーションのために必要です。
上に書いた理由により、英語はビジネスシーンにおいても同様です。

また、英語はインターネット上でおもに使用される言語です。インターネットは世界中で何億人もの人が接続しています。
英語は異なるたくさんの国で使用されていて、その理由は植民地（帝国）時代にイギリスが世界に広げる事に成功したためです。

実例でみるiPhoneアプリ内課金(In App Purchase) アプリへの組み込み

こちらを参考に実装してみたが、課金が成功した際にStoreKitが自動で表示すると思われる最後のダイアログが表示されない。（以前は表示されていたようだ）
テストユーザーで何度試しても課金には成功しているが、ダイアログが表示されない模様。

これは一体・・どこを調べればいいのだろう・・・
スクリーンショットも自分で”課金成功”ってダイアログ出したらいいのだろうか・・・？

ボールとか、つかむ感じですな。

ヘッダにこれ

  b2World* world;
  GLESDebugDraw *m_debugDraw;
  b2Vec2 m_mouseWorld;
  b2MouseJoint *m_mouseJoint;

m_mouseJointはinitでNullいれとかないと落ちるかもしれない。
ソースにこれを追加

- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
	UITouch* myTouch = [touches anyObject];
	CGPoint location = [myTouch locationInView: [myTouch view]];
	location = [[CCDirector sharedDirector] convertToGL:location];
	location = [self convertToNodeSpace:location];

	m_mouseWorld.Set(ptm(location.x), ptm(location.y));
	if (m_mouseJoint != NULL)
	{
		return;
	}

	b2AABB aabb;
	b2Vec2 d = b2Vec2(0.001f, 0.001f);
	aabb.lowerBound = m_mouseWorld - d;
	aabb.upperBound = m_mouseWorld + d;

	// Query the world for overlapping shapes.
	QueryCallback callback(m_mouseWorld);
	world->QueryAABB(&callback, aabb);

	if (callback.m_fixture)
	{

		b2BodyDef bodyDef;
		b2Body* groundBody = world->CreateBody(&bodyDef);

		b2Body* bodyz = callback.m_fixture->GetBody();
		bodyz->SetAwake(true);

		b2MouseJointDef md;
		md.bodyA = groundBody;
		md.bodyB = bodyz;
		md.target = m_mouseWorld;
		md.maxForce = 1000.0f * bodyz->GetMass();

		m_mouseJoint = (b2MouseJoint*)world->CreateJoint(&md);
	}

    [self addNewSpriteWithCoords:location];
}

- (void)ccTouchesMoved:(NSSet*)touches withEvent:(UIEvent*)event
{
	UITouch* myTouch = [touches anyObject];
	CGPoint location = [myTouch locationInView: [myTouch view]];
	location = [[CCDirector sharedDirector] convertToGL:location];
	location = [self convertToNodeSpace:location];

	m_mouseWorld.Set(ptm(location.x), ptm(location.y));

	if (m_mouseJoint)
	{
		m_mouseJoint->SetTarget(m_mouseWorld);
	}
}

- (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
	[self ccTouchesCancelled:touches withEvent:event];
}

- (void)ccTouchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event {
	if (m_mouseJoint)
	{
		world->DestroyJoint(m_mouseJoint);
		m_mouseJoint = NULL;
	}
}

あと、QueryCallback.hはこれ。ヘッダだけです（見たらわかるけど）

#import "Box2D.h"

class QueryCallback : public b2QueryCallback
{
public:
	QueryCallback(const b2Vec2& point)
	{
		m_point = point;
		m_fixture = NULL;
	}

	bool ReportFixture(b2Fixture* fixture)
	{
		b2Body* body = fixture->GetBody();
		if (body->GetType() == b2_dynamicBody)
		{
			bool inside = fixture->TestPoint(m_point);
			if (inside)
			{
				m_fixture = fixture;

				// We are done, terminate the query.
				return false;
			}
		}

		// Continue the query.
		return true;
	}

	b2Vec2 m_point;
	b2Fixture* m_fixture;
};

Cocos2d+Box2dでニュートンの万有引力の法則を表現する。
基本的にBox2dではサポートしてないみたいなので、サンプルを探す。

ー＞
いちいちオブジェクトごとにApplyForceするだけで引力っぽい。
なんだろうこの煮え切らない感じ。

This is very easy.
1.download cocos2d.
2.install.
3.done.

1. Download cocos2d [cocos2d-iphone-1.0.1.tar.gz] from http://www.cocos2d-iphone.org/download

and extract that tar.

2. open shell and execute “install-templates.sh” script on your mac.
however, this script need a root permit.

example sudo ./install-templates.sh -f
