Race Choosing at Beginning of Map?

Race Choosing at Beginning of Map?

How do I make a screen that pops up in the begininning of a map so the player can choose his/her race? Like in Zoator TD, you get to choose between 5 races, and get a tower builder according to which race you chose.

Can someone help?

Thanks,

You would have to make a dialog box system. First, make a dialog variable to store the main box. I'll refer to it as DialogBox. Then make a dialog button variable for every button of the box. So, if you had to choose from Human, Orc, Undead, or Night Elf you would make a DialogBTN_Human, DialogBTN_Orc, DialogBTN_Undead, and DialogBTN_NightElf. Now you would make the following triggers:

Events
--Time - Elapsed game time is 2.00 seconds
Conditions
Actions
--Dialog - Change the title of DialogBox to What race would you like to be?
--Dialog - Create a dialog button for DialogBox labelled Human
--Set DialogBTN_Human = (Last created dialog Button)
--Dialog - Create a dialog button for DialogBox labelled Orc
--Set DialogBTN_Orc = (Last created dialog Button)
--Dialog - Create a dialog button for DialogBox labelled Undead
--Set DialogBTN_Undead = (Last created dialog Button)
--Dialog - Create a dialog button for DialogBox labelled Night Elf
--Set DialogBTN_NightElf = (Last created dialog Button)
--Dialog - Show DialogBox for Player 1 (Red)

Events
--Dialog - A dialog button is clicked for DialogBox
Conditions
Actions
--If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    If - Conditions
        (Clicked dialog button) Equal to DialogBTN_Human
    Then - Actions
        Trigger - Run [Human Setup Trigger] (checking conditions)
    Else - Actions
        Do nothing
--If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    If - Conditions
        (Clicked dialog button) Equal to DialogBTN_Orc
    Then - Actions
        Trigger - Run tirgger <gen> (checking conditions)
    Else - Actions
        Do nothing
--If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    If - Conditions
        (Clicked dialog button) Equal to DialogBTN_Undead
    Then - Actions
        Trigger - Run [Undead Setup Trigger] (checking conditions)
    Else - Actions
        Do nothing
--If (All Conditions are True) then do (Then Actions) else do (Else Actions)
    If - Conditions
        (Clicked dialog button) Equal to DialogBTN_NightElf
    Then - Actions
        Trigger - Run [NightElf Setup Trigger] (checking conditions)
    Else - Actions
        Do nothing

Thanks. I got it to work now.
