多条件下的产量Scala

我有一个

位图

对象，它是一个三维数组，三维度等于3。我想把它分成64x64x3块。为此，我有以下代码段：

val tiles: someType = for {

  x <- bitmap.indices by 64
  y <- bitmap(0).indices by 64


  data = for {
    //For all X and Y within one future tile coordinates
    tx <- x until x + 64
    ty <- y until y + 64
  } yield bitmap(tx)(ty)

...
}

val tiles:someType=for{
这个怎么样

val tiles: someType = for {
  x <- bitmap.indices by 64
  y <- bitmap(0).indices by 64

  data = for {
    //For all X and Y within one future tile coordinates
    tx <- x until math.min(x + 64, bitmap.length)
    ty <- y until math.min(y + 64, bitmap(0).length)
  } yield bitmap(tx)(ty)
}

val tiles:someType=for{
这个怎么样

val tiles: someType = for {
  x <- bitmap.indices by 64
  y <- bitmap(0).indices by 64

  data = for {
    //For all X and Y within one future tile coordinates
    tx <- x until math.min(x + 64, bitmap.length)
    ty <- y until math.min(y + 64, bitmap(0).length)
  } yield bitmap(tx)(ty)
}

val tiles:someType=for{
x@LuisMiguelMejíaSuárez是的，它很有效！看起来很优雅。在你发布答案之前，请看我的编辑，我用64@LuisMiguelMejíaSuárez是的，它很管用！而且看起来很优雅。在你发布答案之前，请看我的编辑，我用64替换了
