Question

我正在以编程方式将切片添加到SKTileMapNode。通过获取正确数量的图块，一切都可以正常工作，只是在尝试将其显示在屏幕上时才出现问题。

您会发现它看起来并不是真正的6x6，但是它应该更大一些，但是如果您查看图块的排列方式，则会在右上角看到5x5，然后相同颜色的大长条。但是现在，检查输出：

0.0 0 0 -0.24247201 1 0 -0.34696135 2 0 -0.42960075 3 0 -0.622688 4 0 -0.75301373 5 0 -0.1590038 0 1 -0.3293429 1 1 -0.4532277 2 1 -0.5414402 3 1 -0.6365295 4 1 -0.74014837 5 1 -0.19817059 0 2 -0.33490476 1 2 -0.5156779 2 2 -0.6816129 3 2 -0.74775416 4 2 -0.7614269 5 2 -0.232784 0 3 -0.38513133 1 3 -0.58570683 2 3 -0.7466342 3 3 -0.8207564 4 3 -0.8160349 5 3 -0.35956064 0 4 -0.4724255 1 4 -0.64021933 2 4 -0.7772983 3 4 -0.8449071 4 4 -0.8870924 5 4 -0.46846196 0 5 -0.53693193 1 5 -0.7096603 2 5 -0.8055851 3 5 -0.874175 4 5 -0.97741973 5 5

正好有36个图块，这意味着长条彩色条是一个图块。我该如何解决？

    }
    //terrainTiles.anchorPoint = CGPoint(x: 0,y: 0)
    self.addChild(terrainTiles)
    print(terrainTiles.mapSize)`

如果有人可以帮助，这是我的代码
