I want to know how to write a code of choosing only 2 numbers and I'm not talking about ranging between values. I like the code to pick absolute numbers that is written in the argument.

Hi there,

i'm not 100% sure, if i understand your question correctly, but have a look at this functions:

```
func randa(array : Array):
# Pick random number from input-array
return array[randi() % len(array)]
func randa2(array : Array):
# Create an array with 2 numbers from the input-array
return [randa(array), randa(array)]
func randav(array : Array):
# Create an Vector2 with numbers from the input-array
return Vector2(randa(array), randa(array))
```

You can try/use it like this:

```
func _ready():
# Example
randomize()
var array : Array = [0, 13, 42, 69, 101, 1337] # Random numbers
# Example with 1 Number
var number_1 = randa(array)
var number_2 = randa(array)
print("1: ", number_1)
print("2: ", number_2)
# Example with Array
var numbers = randa2(array)
print("[]: ", numbers)
# Example with Vector2
var vector = randav(array)
print("v2: ", vector)
```

This might do what you want :)

I visual script, there's a node ( box ) called rand ( integer ) and, randf ( float ) . . The boxes sort of creates a ' near ' random number, from algorhitms, because computers can't be completely random . .

randi returns an integer, randf returns a random float, maybe those are ones, you are in need of <3
