1.普通视图获取对应位置图素

CCTMXLayer *layer=map->layerNamed("Layer 0");

CCSize s=layer->getLayerSize();

CCPoint touchPoint=touch->getLocationInView();

touchPoint=CCDirector::sharedDirector()->convertToGL(touchPoint);

int indexx=(touchPoint.x)/map->getTileSize().width;

int indexy=map->getMapSize().height-(touchPoint.y)/map->getTileSize().height;

sprite=layer->tileAt(ccp(indexx,indexy));

sprite->setScale(2);

//map->getMapSize().height 获取图片的长宽像素个数

//getTileSize().height 获取一个图素的高度与宽度

总体思路就是具体位置除以图素的宽高，但这里需要注意，在Y轴的处理上略有不同。因为Cocos2D-X中的坐标系中，Y轴是从下到上一次增加的，而地图中的行数则是从上到下增加的，这就需要做一个转换，用总的函数减去Y轴坐标除以图素高，结果才是所有图素的函数。

2.45度角视图获取对应图素

CCPoint HelloWorld::converttto2d(float x,float y)

{

CCTMXTiledMap *map=(CCTMXTiledMap *)getChildByTag(1);

int mapWidth=map->getMapSize().width*map->getTileSize().width;

int mapHeight=map->getMapSize().height*map->getTileSize().height;

double distanse,sin1,sin11,sin22,cos11,cos1;

int d2x,d2y;

double mystatic5=sqrt(5.0);

double mystatic=16*mystatic5;

if (x>mapWidth/2)

{

distanse=sqrt((x-mapWidth/2)*(x-mapWidth/2)+(mapHeight-y)*(mapHeight-y));

sin1=(mapHeight-y)/distanse;

cos1=(x-mapWidth/2)/distanse;

sin11=(sin1*2-cos1)/mystatic5;

cos11=(sin1+cos1*2)/mystatic5;

d2y=distanse*5/4*sin11/mystatic;

sin22=(2*sin1+cos1)/mystatic5;

d2x=distanse*5/4*sin22/mystatic;

return ccp(d2x.d2y);

}

else

{

distanse=sqrt((mapWidth/2-x)*(mapWidth/2-x)+(mapHeight-y)*(mapHeight-y));

sin1=(mapHeight-y)/distanse;

cos1=(mapWidth/2-x)/distanse;

sin11=(sin1*2-cos1)/mystatic5;

cos11=(sin1+cos1*2)/mystatic5;

d2x=distanse*5/4*sin11/mystatic;

sin22=(2*sin1+cos1)/mystatic5;

d2y=distanse*5/4*sin22/mystatic;

return ccp(d2x,d2y);

}

}
