【cocos2dx 3.2】瓦片地图制作，cocos2dx瓦片
使用Tiled编辑地图
每一个图层只能放一种瓦片
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，做相应的操作
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));
}
}
