How-to: Let the player make a yes/no choice in a script

[HouseOfHam]

There is more than one way to do this, but the easiest, in my option, is by using the advisor.

Again, like in my other tutorials, I'm going to use an example to demonstrate how this is done. The example I'm going to use is offering the player a chance to buy a lottery ticket at the beginning of every turn.

First, we'll need to set up an advice thread. This involves adding stuff to 2 files.

1. export_descr_advice.txt

;-----------------------------------------------
AdviceThread PromptThread
    GameArea Campaign

    Item PromptItem1
        Uninhibitable
        Verbosity  0
        Threshold  1
        MaxRepeats  0
        RepeatInterval  1
        Attitude Normal
        Presentation Default
        Title PromptTitle1
        Text PromptText1

and 2. text\export_advice.txt

{PromptTitle1}Test your luck
{PromptText1}Would you like to buy a lottery ticket for a chance to win 10k? The cost of the ticket is 1 gold. Click on the advisor portrait to try your luck, or on the dismiss button to decline.

Now, the code that you'll add to the script:

declare_counter isOfferActive

monitor_event FactionTurnStart FactionIsLocal

    advance_advice_thread PromptThread 1

    ; This assumes that you have declare_show_me at the top of the script,
    ; which opens the advisor text box for you automatically.
    ; If you do not, uncomment the 2 lines below.
    ;select_ui_element advisor_portrait_button
    ;simulate_mouse_click lclick_up

    set_counter isOfferActive 1
end_monitor

; Offer accepted
monitor_event ButtonPressed ButtonPressed advisor_portrait_button
          and I_CompareCounter isOfferActive = 1

    console_command add_money -1            ; Cost of the lottery ticket

    if RandomPercent > 99
        console_command add_money 10000   ; You won!
    end_if

    set_counter isOfferActive 0
end_monitor

; Offer rejected
monitor_event ButtonPressed ButtonPressed advisor_dismiss_button
          and I_CompareCounter isOfferActive = 1

    ; greedy bastard! charge him 1 gold anyways!
    console_command add_money -1

    set_counter isOfferActive 0
end_monitor

And it's that simple!

What about a True or False quiz on ancient history? and if you get it right you get units or something.

[HouseOfHam]

My tutorial only demonstrates the concept. What/where/how you choose to use it is up to you.

With a little work, implementing a quiz is certainly possible. You'd need to create a separate advice thread for each question and setup a counter so you have a way to tell which question the player was asked and react to their answer appropriately in the two monitors that process the answer.

Great tuto (yet again) HouseOfHam !

I'm sorry if i sound like a total noob , but where do i have to put the actual script ?

Also , is there a trigger needed ?

[HouseOfHam]

Looks like you've already found the answer to that.
