[Cocos2dx 3.2] tile map creation

Use tiled to edit a map

• Each layer can only contain one tile.
• The tile size should be a multiple of 32*32.
• Set path coordinates in the object Layer
• Obtain the coordinates in the object Layer in the main program and perform corresponding operations.

Set the pocket genie class:
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;//按照路径移动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));}}
