【cocos2dx 3.2】瓦片地图制作

使用Tiled编辑地图

• 每个图层仅仅能放一种瓦片
• 瓦片的大小最好是32*32的倍数
• 对象层里面设置路径的坐标
• 主程序中获取对象层中的坐标，做对应的操作

设置口袋精灵类：

Monster.h

#include "cocos2d.h"

USING_NS_CC;

class Monster : public Sprite

{

public:

	virtual bool init(Vector<Node*> points);

	static Monster* create(Vector<Node*> points);

	//用于获取对象层的坐标

	Vector<Node*> p;

	Vector<Node*>::iterator start;

	//精灵

	Sprite *s;

	//依照路径移动

	void moveByPath();

	//种类随机数

	int ranNum;

};

Monster.cpp

#include "Monster.h"

Monster* Monster::create(Vector<Node*> points)

{

	auto monster = new Monster();

	monster->init(points);

	monster->autorelease();

	return monster;

}

bool Monster::init(Vector<Node*> points)

{

	Sprite::init();

	//设置随机数，控制出场精灵种类

	srand(time(NULL));

	ranNum = rand()%5;

	p = points;

	start = p.begin();

	switch (ranNum)

	{

	case 0 :

			{

				s = Sprite::create("1.png");

				break;

			}

	case 1:

			{

				s = Sprite::create("2.png");

				break;

			}

	case 2:

			{

				s = Sprite::create("3.png");

				break;

			}

	case 3:

			{

				s = Sprite::create("4.png");

				break;

			}

	case 4:

			{

				s = Sprite::create("5.png");

				break;

			}

	}

	s->setPosition((*start)->getPosition());

	addChild(s);

	return true;

}

//沿着路径移动

void Monster::moveByPath(){

	++start;

	if(start == p.end()){

		s->removeFromParent();

	}

	else{

		Point a = Point((*start)->getPosition());

		s->runAction(Sequence::create(MoveTo::create(2,a),CallFuncN::create(CC_CALLBACK_0(Monster::moveByPath,this)),NULL));

	}

}

主场景类

	//存放对象层里的坐标

	Vector<Node*> points;

	Vector<Node*>::iterator startPoint;

	//加入物体

	//用于控制时间间隔

// on "init" you need to initialize your instance

bool HelloWorld::init()

    //////////////////////////////

    // 1. super init first

	if ( !LayerColor::initWithColor(Color4B(255,255,255,255)) )

    {

        return false;

    }

    Size visibleSize = Director::getInstance()->getVisibleSize();

    Point origin = Director::getInstance()->getVisibleOrigin();

	//加入物理边界

	auto body = PhysicsBody::createEdgeBox(visibleSize,PHYSICSBODY_MATERIAL_DEFAULT,3);

	auto node = Node::create();

	node->setPhysicsBody(body);

	node->setPosition(visibleSize.width/2,visibleSize.height/2);

	addChild(node);

	//加入地图文件

	auto map = TMXTiledMap::create("pokamon.tmx");

	map->setPosition(200,0);

	addChild(map);

	//获得对象层中的坐标,存在向量里

	TMXObjectGroup* objectGroup = map->getObjectGroup("monster");

	ValueVector object = objectGroup->getObjects();

	for (ValueVector::iterator it = object.begin(); it != object.end(); it++) {

		ValueMap m = obj.asValueMap();

		auto node = Node::create();

		node->setPosition(m.at("x").asFloat()+200,m.at("y").asFloat());

		points.pushBack(node);

	}

	//重置时间

	resetTime();

	//开启计时器

	scheduleUpdate();

    return true;

}

void HelloWorld::update(float dt)

{

	++oldTime;

	if (oldTime == curTime)

	{

		resetTime();

		addMonster();

	}

}

void HelloWorld::resetTime()

{

	oldTime = 0;

	curTime = 40;

}

void HelloWorld::addMonster()

{

	auto hero = Monster::create(points);

	hero->moveByPath();

	addChild(hero);

}

void HelloWorld::menuCloseCallback(Ref* pSender)

{

#if (CC_TARGET_PLATFORM == CC_PLATFORM_WP8) || (CC_TARGET_PLATFORM == CC_PLATFORM_WINRT)

	MessageBox("You pressed the close button. Windows Store Apps do not implement a close button.","Alert");

    return;

#endif

    Director::getInstance()->end();

#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)

    exit(0);
