Time for action — creating 2D arrays

Creating arrays with more than one dimension in Monkey is a little tricky. We can create a function that lets us set up a 2D array, using the following steps:

  1. Add the function Create2DArray to the treasurechest.monkey file. Its parameters are the number of cells required for both the dimensions. The return type is a 2D array of the type INT.
    Function Create2DArray:Int[][]( columns:Int, rows:Int)
  2. Define a local two-dimensional array of the type INT, initialized in the first dimension.
    Local a:Int[][] = New Int[columns][]
  3. Start a FOR loop ranging from 0 to columns.
    For Local c:Int = 0 Until columns
  4. Define a new array of rows in each column.
    a[c] = New Int[rows]
  5. Close the FOR loop, return the array, and close the function.
    Next
Return a
End

What just happened?

You have just created a function that will let you set up a 2D array in Monkey. It is reusable for other games that you will create in the future.
