I use Godot 3.

Hello,
Lets's say I have the following array and it is structured like this....
slots[0] = ""
slots{1] = 11
slots[2] = 1
slots[3] = ""
slots[4] = 4

But I need some type of code that ill actrually sort the array structure so it ends up like this instead...
slots[0] = 1
slots{1] = 4
slots[2] = 11
slots[3] = ""
slots[4] = ""

Please help?

func _ready():
    var arr = ["",11,1,"",4]
    arr.sort_custom(self, "customComparison")
    print (arr)


func customComparison(a, b):
    if typeof(a) != typeof(b):
        return typeof(a) < typeof(b)
    else:
        return a < b

This code depends on integer values assigned to types. Currently int is 2 and string is 4. If it ever changes, which is doubtful, results can be different.

Edit:
And here's code that allows to specify order of types in sorting:

const TypeOrder = [TYPE_STRING, TYPE_INT]

func customComparison2(a, b):
    if typeof(a) != typeof(b):
        if typeof(a) in TypeOrder and typeof(b) in TypeOrder:
            return TypeOrder.find( typeof(a) ) < TypeOrder.find( typeof(b) )
        else:
            return typeof(a) < typeof(b)
    else:
        return a < b

In this case strings are before integers.

Arrays are sorted in place.

arr.sort()

turns arr into a sorted array.

it doesn't return the array so you don't need to do

newarr = arr.sort()
