如何通过点击使用CCLayerPanZoom类的等距平铺地图来放置图块

Question

我有一张平铺地图。我用cocos2D。等轴测图有一个CCLayerPanZoom。用于缩放和滚动。现在我想在我按下它的位置添加一个瓷砖。这是行不通的。它将瓷砖插入错误的位置。

是否与地图缩放有关（缩放和滚动是可行的）。？

-(void)ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event{

    touchLocation = [touch locationInView: [touch view]];   
    touchLocation = [[CCDirector sharedDirector] convertToGL: touchLocation];
    touchLocation = [self convertToNodeSpace:touchLocation];



    CGPoint playerPos = _player.position;
    CGPoint diff = ccpSub(touchLocation, playerPos);
    if (abs(diff.x) > abs(diff.y)) {
        if (diff.x > 0) {
            playerPos.x += self.map.tileSize.width;
        } else {
            playerPos.x -= self.map.tileSize.width; 
        }    
    } else {
        if (diff.y > 0) {
            playerPos.y += self.map.tileSize.height;
        } else {
            playerPos.y -= self.map.tileSize.height;
        }
    }
    //player.position = playerPos; // Todo: Trymove

    if (playerPos.x <= (self.map.mapSize.width * self.map.tileSize.width) &&
        playerPos.y <= (self.map.mapSize.height * self.map.tileSize.height) &&
        playerPos.y >= 0 &&
        playerPos.x >= 0 ) {
        [self setPlayerPosition:playerPos];
    }

    if([TileMapLayer isOnTheMapMoreRestrictive:touchLocation map:self.map mapsize:self.map.mapSize.width] )
        [self plantObject:touchLocation];
    else
        CCLOG(@"Outside possition");

   [self setDotPosition: [self tilePosFromLocation:touchLocation tileMap:self.map]];

}



-(void)plantObject:(CGPoint) location{

    punkt = [CCSprite spriteWithFile:@"tree.png"];
    punkt. position = [self tilePosFromLocation:location tileMap:self.map];
    [_map  addChild:punkt z:4];
}
