How do I use foreach with my array in Scala?

Question

I have this array:

  var walls: Array[LineSprite] = new Array[LineSprite](20)

And I want to make is so that for all the items in the array between 11 and less than or equal to 19, the start is set to -2,-2 and the end is set to -3,-3.

To do that for one of the items it would look like this:

walls(0).setStart(-2,-2)
walls(0).setEnd(-3,-3)

How would I do what I want using foreach?

Thanks

Do you mean this?

for (i <- 11 to 19) {
  walls(i).setStart(-2,-2)
  walls(i).setEnd(-3,-3)
}

This translates to:

(11 to 19) foreach { i =>
  walls(i).setStart(-2,-2)
  walls(i).setEnd(-3,-3)
}
