Arrays

Map array

points.assign(points.map(func(point : Vector2i) -> Vector2i:
    return point + Vector2i(-1, 0)
    ))

• Map:

  • Performs mapping and returns the mapping result.

  • Return is always of type Array .

• Assign:

  • Takes all elements from an array and puts them into itself, converting types.

    • In this case, converts the return of map  to Array[Vector2i] , since points : Array[Vector2i] .

  • Assign seems to clear the current array, but it's strange.
