wrong position of tile map when i convert to retina display

Question

I follow guide of converting tile map for retina display by changing size of width and height to double size and position of object too. but the result on normal display is

Answer 1

Me also observed same problem with cocos2D tile map and finally resolved by dividing CC_CONTENT_SCALE_FACTOR. In retina mode it gives 2.0.

CCTMXObjectGroup *objects = [tileMap objectGroupNamed:NN_TILE_MAP_OBJECT_LAYER];

CGSize s = [[CCDirector sharedDirector] winSize];

NSMutableDictionary *newtonPos = [objects objectNamed:NN_NEWTON_POS];        

if(newtonPos)
{
    float x = ([[newtonPos valueForKey:@"x"] floatValue])/CC_CONTENT_SCALE_FACTOR();
    float y = [[newtonPos valueForKey:@"y"] floatValue]/CC_CONTENT_SCALE_FACTOR();

    MyGameScreen *p = (MyGameScreen*)self.parentLayer;
    p.gameActor.position = ccp(x, y);
}

//I used this function to get chord..

- (CGPoint)getTileCoordForPosition:(CGPoint)position
{
    int maxTileCol = self.mapSize.height; 

    int x = ( (position.x-self.position.x)/TILE_SIZE);
    int y = maxTileCol - ( ((position.y)-self.position.y)/TILE_SIZE);

    if( x >= TILE_IN_ROW)
        x = TILE_IN_ROW - 1;

    if( y >= TILE_IN_COL)
        y = TILE_IN_COL - 1;

    return ccp(x, y);

}
