Yes/No Event Tutorial

Okay, something must be VERY wrong with my references.
I have tried putting in your script, but my game now CTD when i input your code

(somehow i find that intriguing, i like the challenge)

I tried searching a bit deeper into the log (*script* trace) and found the following:

Any ideas?
It kind of seems like it still goes by M2tw data, instead of kingdoms (descr_events_image)

**Wettergren** · February 24, 2017, 05:10 PM

It worked! Thank you..

I'm fairly confident that it was rooted in the Virtual "Home Depot"
So deleting them seems to have done the job...

You seem to be running a 'provincial campaign' but the relevant file is in the shared data folder - that shouldn't really make a difference.

Line 3939 got executed, else there wouldn't be an entry, something happened after that. I am assuming the two historic_event entries for mission_issued exit? {MISSION_ISSUED_TITLE} and {MISSION_ISSUED_BODY}?

Have you ever sorted out your virtual store? If not then run this tutorial from step 3 onward and delete the m2tw folder in the virtual store directory if it is present.

check in your descr_event_images files if this entry is in there completely as underneath, blue is the placement of the accept\decline symbols on the message:

Code:

historic_event
    icon    historic
    importance high
    heading_items    3
    footer_items    1
    format
    {
        string    center verdana black
        image    center
        spacer    8
        multistring    left verdana_sml khaki left
        condition
        {
            true
            {
                group center 8
                {
                    accept    right
                    decline   left
                }
            }
            false
            {
                group center 8
                {
                    spacer 1    ; dummy item to fix event message formatting wrt header and footer items
                }
            }
        }
    }

**Gigantus** · February 24, 2017, 09:45 PM

Looks fine, just a note:

Code:

    monitor_event CharacterSelected CharacterIsLocal
        and FactionwideAncillaryExists HK_Kalmar
        and FactionwideAncillaryExists Duke_Denmark
        
        console_command remove_ancillary this Duke_Denmark
    end_monitor

You have to expect error message about the removal of the ancillary in the case the ancillary exists but not wit the selected character. Rather use HasAncType to test if the character has this ancillary. You will need to edit the EDA and give the ancillary a unique type entry so that this works properly - the ancillary name does not get tested here.
I would also suggest to have a monitor that tests for the existence and then sets a counter that can be used to terminate all these testing monitors (good housekeeping for the win!)

Code:

    monitor_event FactionTurnstart I_EventCounter kalmar_union = 2
        and not I_WorldwideAncillaryExists Duke_Denmark
        set_event_counter no_DukeDenmark 1
        terminate_monitor
    end_monitor
    
    monitor_event CharacterSelected CharacterIsLocal
        if I_EventCounter no_DukeDenmark > 0   ; terminate if ancillary doesn't exist
            terminate_monitor
        end_if
        and FactionwideAncillaryExists HK_Kalmar
        and Has AncType [type entry of Duke_Demnamrk ancillary]
        console_command remove_ancillary this Duke_Denmark
    end_monitor

**Xagamon** · August 22, 2017, 05:03 AM

Hello everyone,
So, I've been doing experiments with these yes/no decisions and I attempted to make one that is supposed to cause a type of magical effect (really, just remove fog of war until the end of the turn), it doesn't work, no effects happen whatsoever. Here is what I have now:

Code:

monitor_event PreFactionTurnStart FactionIsLocal
    set_event_counter air_magic_accepted 0
    set_event_counter air_magic_declined 0
end_monitor 

monitor_event FactionTurnStart FactionIsLocal
    and FactionBuildingExists >= alchemy_school
    and I_LocalFaction scotland
    historic_event air_s_reveal true
end_monitor
monitor_event EventCounter EventCounterType air_magic_accepted
    and I_EventCounter air_magic_accepted == 1
    add_money scotland, -10000
    console_command toggle_fow
end_monitor

No effects, not even a money deduction. Any ideas? Is this even possible?

**Gigantus** · August 22, 2017, 05:58 AM

Your event is called 'air_s_reveal' and the accepted counter\condition is called 'air_magic' - no surprise here: it has to be same name.

Code:

monitor_event PreFactionTurnStart FactionIsLocal
    set_event_counter air_magic_accepted 0
    set_event_counter air_magic_declined 0
end_monitor 

monitor_event FactionTurnStart FactionIsLocal
    and FactionBuildingExists >= alchemy_school
    and I_LocalFaction scotland
    historic_event air_magic true
end_monitor
monitor_event EventCounter EventCounterType air_magic_accepted
    and I_EventCounter air_magic_accepted == 1
    add_money scotland, -10000
    console_command toggle_fow
end_monitor

**Xagamon** · August 22, 2017, 12:01 PM

Cool! Thanks!
It worked. Here's what I changed it too:

Code:

monitor_event PreFactionTurnStart FactionIsLocal
    set_event_counter air_s_reveal_accepted 0
    set_event_counter air_s_reveal_declined 0
end_monitor 

monitor_event FactionTurnStart FactionIsLocal
    and FactionBuildingExists >= alchemy_school
    and I_LocalFaction scotland
    historic_event air_s_reveal true
end_monitor
monitor_event EventCounter EventCounterType air_s_reveal_accepted
    and I_EventCounter air_s_reveal_accepted == 1
    add_money scotland, -10000
    console_command toggle_fow
end_monitor

But now I'm having trouble undoing this. My plan was to deactivate this at the beginning of the next turn, but that isnt happening. AND, the event message keeps appearing every turn.

Here's what I got:

Code:

monitor_event FactionTurnStart FactionIsLocal
    and I_CompareCounter air_s_reveal_accepted == 1
    set_counter air_s_reveal_accepted 0
    console_command toggle_fow
end_monitor

**Gigantus** · August 22, 2017, 07:43 PM

If this is a one time event then simply terminate the monitors. You also don't need the first monitor then:

Code:

monitor_event FactionTurnStart FactionIsLocal
    and FactionBuildingExists >= alchemy_school
    and I_LocalFaction scotland
    historic_event air_s_reveal true
    terminate_monitor
end_monitor

monitor_event EventCounter EventCounterType air_s_reveal_accepted
    and I_EventCounter air_s_reveal_accepted == 1
    add_money scotland, -10000
    console_command toggle_fow
    terminate_monitor
end_monitor

**Xagamon** · August 23, 2017, 12:59 AM

What about if I wanted this to be random at times? Like I planned on adding a random trigger. My hope was for this to have a low % chance of happening from time to time and be an asset that shows up.

**Gigantus** · August 23, 2017, 02:15 AM

You could generate a random number and then test for that in the conditions before triggering the event:

Code:

monitor_event FactionTurnStart FactionIsLocal
    and FactionBuildingExists >= alchemy_school
    and I_LocalFaction scotland
    generate_random_counter air_s_reveal_chance 1 20  ; creates counter with value between 1 and 20
    if I_EventCounter air_s_reveal_chance = 1  ; 5% (100\20) chance of this happening
        historic_event air_s_reveal true
    end_if
end_monitor

monitor_event EventCounter EventCounterType air_s_reveal_accepted
    and I_EventCounter air_s_reveal_accepted == 1
    add_money scotland, -10000
    console_command toggle_fow
    set_event_counter air_s_reveal_accepted 0  ; resetting counter for next time
end_monitor

**Xagamon** · August 23, 2017, 01:14 PM

Not quite, made the trigger stop.
I added this as a random modifier:
and RandomPercent < 5.

So now the message stops appearing every turn, and that's good. A step in the right direction. But the FOW still doesn't reappear unless I enter it manually.

This is it now:

Code:

monitor_event FactionTurnStart FactionIsLocal
    and FactionBuildingExists >= alchemy_school
    and I_LocalFaction scotland
    and RandomPercent < 5
    historic_event air_s_reveal true
end_monitor
monitor_event EventCounter EventCounterType air_s_reveal_accepted
    and I_EventCounter air_s_reveal_accepted == 1
    add_money scotland, -10000
    console_command toggle_fow
end_monitor

monitor_event FactionTurnStart FactionIsLocal
    and I_CompareCounter air_s_reveal_accepted == 1
    and I_LocalFaction scotland
    console_command toggle_fow
    set_event_counter air_s_reveal_accepted 0 
end_monitor

**Gigantus** · August 23, 2017, 07:55 PM

toggle_fow is a bit iffy: can't say I managed to get it working within a monitor.

**Xagamon** · August 25, 2017, 05:10 AM

It is possible to do the command in reverse. I tested by ending turn a few times and the same event option would appear (with the random chance), and when I select 'accept' the FOW comes back (with another 10000 deduction, as it says in the script).

I noticed something with the second part:

Code:

monitor_event FactionTurnStart FactionIsLocal
    and I_EventCounter air_s_reveal_accepted == 1
    and I_LocalFaction scotland
    console_command toggle_fow
    set_event_counter air_s_reveal_accepted 0 
end_monitor

This is supposed to 'reverse' the effect, as Im sure you guessed. I experimented with adding an event message to appear and to add money to see if those would trigger. Nothing happened at all with this. In my impression, this part is not triggering at all.

**Gigantus** · August 25, 2017, 07:22 AM

My bad: CompareCounter in the third monitor doesn't work at all with event counters - it needs to be I_EventCounter. I should have noticed that right from the beginning.

**Xagamon** · August 25, 2017, 11:50 AM

Oh, no. Not your bad. I already tried to run both EventCounter and CompareCounter. Neither work, the third monitor simply does not fire at all.

**Gigantus** · August 25, 2017, 09:23 PM

The third monitor may not fire because of the timing of the event. Try changing it to FactionTurnEnd. I have also changed the 'local faction' condition a bit.

Code:

monitor_event FactionTurnEnd FactionType scotland
    and I_EventCounter air_s_reveal_accepted == 1
    and FactionIsLocal
    console_command toggle_fow
    set_event_counter air_s_reveal_accepted 0 
end_monitor

**Xagamon** · August 28, 2017, 11:28 AM

It worked! I let it run a few times in the same campaign going back and forth, it works solidly so far! Thanks a bunch!
You might see me here again, I'm gonna be testing some strange scripts to see whatever kind of 'magic effect' I can do. If anything works, I'll post it here for others.
