[Wurst] Dialogs

[Faint.Smile77]

Hello i'm new to wurst and just started learning it yesterday. I searched everywhere for a solution but since i didn't know what to look for exactly, I couldn't get the right answers.
I tried to create a dialog as when the game starts the player X gets the dialog and chooses his race. Since this is a single player map the dialog should only be shown to one player (player 1). At the last line of my code (DialogDisplay(player(0), this, true) the player(o) gets an error saying player is not defined yet. How can i define the player(s) i want to show the dialog to?

Spoiler: Wurst Code

package Hello
import Dialog
init
    print("Hello World")
    printTimed("This is a timed msg(20.3 Seconds).", 20.3)
// DIALOG
function createDialog() returns dialog
    return DialogCreate()

function dialog.addButton0() returns button
    return DialogAddButton(this,"Human",72)

function dialog.addButton1() returns button
    return DialogAddButton(this,"Dwarf",68)

function dialog.addButton6() returns button
    return DialogAddQuitButton(this,true,"Quit",81)
   
public function dialog.setMessage()
    DialogSetMessage(this, "Select your race")

function dialog.display()
    DialogDisplay(player(0), this, true)

There's already a DialogBox utility exists in standard library for you to use, with an example usage.
