Hello, in my text adventure you can play mini-games to increase your total cash.
In one of them, the game sets a variable to a random number between 1 and 36.
I want to include a script where the game checks if the random number is an even or an odd number so that it can set another variable to the appropriate string.

The only problem is, I have no idea how to do that or if it's even possible. Does anyone know?

    bool = false
   if (int % 2 = 0) {
        bool = true
    }

  </function>

Sorry, I'm completely loss when it comes to functions or scripts like this. I don't know where it goes or what I should change.

Check if the number divided by 2 is equal to the integer of the same number divided by 2. If they are equal it is even else odd.

So... if variable / 2 = Int(variable /2) then even else odd.

Hopefully you can do this in the GUI without too much trouble.

Sorry I haven't got an actual image to show, but it has been a while since I have done anything in Quest.

Good idea, R2T1!

It works! Thanks KV and R2T1.

@KV thanks for simplifying it further by using the MOD operator. I thought of it later but didn't update my post.

the modulus operator (%) / operation, does division, but it finds/gets the REMAINDER

the remainder is useful for odd/even (factoring/divisibility of specifically using '2'), factoring/divisibility (of using any number), and cyclic (example: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, ... Time especially: seconds, minutes, hours, etc), uses/needs

even (or odd) number: any even number divided by 2 will have no (zero: 0) remainder (and if it's not 0, then it will be a 1, and thus also is an odd number), (any number divided by 2 will either have no/zero/0 remainder or 1 as it's remainder), so:

get input {
  if (IsInt (result)) {
    number = ToInt (result)

    if (number % 2 = 0) {
      msg ("The number " + number + " is an even number")
    } else {
      msg ("The number " + number + " is an odd number")
    }

  } else {
    msg ("wrong input, please try again, typing in an integer (non-decimal number value: ..., -9999, -3, 0, 1, 6, 555, ...), please")
  }
}

// or:

get input {
  if (IsInt (result)) {
    number = ToInt (result)

    if (number % 2 = 1) {
      msg ("The number " + number + " is an odd number")
    } else {
      msg ("The number " + number + " is an even number")
    }

  } else {
    msg ("wrong input, please try again, typing in an integer (non-decimal number value: ..., -9999, -3, 0, 1, 6, 555, ...), please")
  }
}
