An Intermediate Guide to Scripting

AN INTERMEDIATE GUIDE TO SCRIPTING
BACKGROUND SCRIPTS

By Epistolary Richard & Myrddraal
___________________________

In A Beginner Guide to Scripting we identified two different types of scripts: campaign scripts and show_me scripts, and went further to divide show_me scripts into event scripts and background scripts.

The Beginner Guide taught us the basics of using the event script – which is a script that runs only for a moment, making a change to the game world. These must be manually activated when their trigger event occurs.

This guide takes us a little deeper into the world of the background script – this is a script that is running constantly in the background of the game. It must be activated at the start of the game, and then manually reactivated each time the game is reloaded.

The Benefits of a Background script

There are two major limitations to the use of event scripts. The first is that it requires the player to click on the show_me button each and every time you want to make a change to the game environment.

The second, more importantly, is that the event script trigger can only ever be something that will happen in the player’s own turn. If it occurs outside of the player’s turn then the player will never get the chance to click on the show_me button as the advisor will appear and disappear during the AI turn.

This is why modders use background scripts as the main driver for their scripting features as they require the player only to make a single click each time the game is reloaded to run all their features and it gives them complete flexibility as to when and how their features are implemented.

In fact, the very first scripts that Myrddraal released – the Multiple Turns per Year script and the Hot Seat Beta script – were both background scripts.

In truth, every mod with significant scripting features will end up making use of all of the different types of script – background, event and campaign – as they all compliment each other.

What is a Background script?

As all show_me scripts, the background script is activated through the advisor. It must have all the components of a show_me script as listed in the Beginner Guide, namely trigger, advice thread and script.

The fundamental difference between an event script and a background script is that a background script is supposed to keep running and not terminate until the game is quit.

This is accomplished with the addition of a simple piece of code to the script – a While loop:

Code:

script declare_counter loop set_counter loop 0 ; Insert your background script here while I_CompareCounter loop = 0 end_while end_script

Once activated, this script will never terminate as when it reaches the end_while it will loop back to the I_CompareCounter.

Now we have the script working all the time, however, we have to incorporate the triggers we want to use into the script itself, instead of the export_descr_advice file. To do that, we need to use new syntax:

Monitors, If statements and While loops

The monitor event/monitor conditions/if/while commands are very much like the triggers for advice threads.

Basically they are for checking conditions.

If statements

Like for example if you have a counter called no

Code:

script declare_counter no set_counter no 1 If I_CompareCounter no 1 Insert code here end_if end_script

What this will do is at the stage at which it reaches the If line, it will check counter no, if counter no is 1 then it will run the code, if not it will skip to the end_if.

While loops

A while loop will repeat itself whilst its conditions are true.

Code:

script declare_counter no set_counter no 0 While I_CompareCounter no = 0 Insert code here end_while end_script

When the script runs through, everytime it reaches and end_while, it will check the conditions, and if they are still true, it will jump back to the while statement. Basically looping that bit of code. In this example, the script will keep running forever, because the condition is that no is zero, and there is no code to stop this.

While monitors can be extreemly usefull for pausing the script until something happens.

Code:

While I_TurnNumber = 0 end_while

This will pause the script until the player ends the first turn (turn 0)

It can also be very helpfull if you do not want a script to end before a monitor is triggered. (see below)

Monitors

Condition monitors

Code:

script declare_counter loop set_counter loop 1 declare_counter no set_counter no 0 monitor_conditions I_CompareCounter no = 1 Insert code here terminate_monitor end_monitor campaign_wait 10 set_counter no 1 while I_CompareCounter loop = 1 end_while end_script

The difference between a Monitor and an If statement is that the conditions for an if statement are checked when the if statement is reached, and not again. A monitor can be declared at the beginning of the script and will then be checked continuously.
In the example above, the monitor is declared, but the counter no is not 1. As soon as no changes to 1 (after waiting 10) the monitor is triggered and the code inside it is run.

Event monitors

Code:

script declare_counter loop set_counter loop 1 monitor_event buttonpressed buttonpressed end_turn TrueCondition Insert code here terminate_monitor end_monitor while I_CompareCounter loop = 1 end_while end_script

An event monitor is basically a trigger using certain conditions. For example the pressing of a button. In this case, on the pressing of the end turn button, the code inside the monitor will be run.

The difference between terminate_monitor and end_monitor

With some monitors, you will see both terminate_monitor and end_monitor at the end. This basically determines whether the monitor can be triggered more than once. If you include both, the monitor can only be triggered once, then it cannot be used again. If you only include the end_monitor, then the monitor can be enabled several times.

And statements

And statments can be used with monitors, if statements and while loops. This is for multiple conditions. For example:

Code:

script declare_counter noone declare_counter notwo declare_counter nothree set_counter noone 1 set_counter notwo 1 set_counter nothree 1 monitor_conditions I_CompareCounter noone = 1 and I_CompareCounter notwo = 1 and I_CompareCounter nothree = 1 Insert code here terminate_monitor end_monitor if I_CompareCounter noone = 1 and I_CompareCounter notwo = 1 and I_CompareCounter nothree = 1 Insert code here end_if end_script

A full list of events, conditions & commands can be found here:
https://forums.totalwar.org/vb/showthread.php?t=54299

Now, that’s all a lot to take in. So let’s try some examples:

More More Money
Here we give the player a little monetary boost each turn. It’ll happen automatically, no need for him to manually activate it.

For the event to trigger it, I’m going to choose FactionTurnStart and I want it only at the start of the player’s turn so I’m going to use the FactionIsLocal conditional.

Code:

script declare_counter loop set_counter loop 0 monitor_event FactionTurnStart FactionIsLocal console_command add_money 100 end_monitor while I_CompareCounter loop = 0 end_while end_script

Now, at the beginning of each turn, the player’s treasury will increase by 100.

Simple enough. Let’s make it more complicated.

Here is a script that will make it considerably harder for a player to amass a huge treasury:

Code:

script declare_counter loop set_counter loop 0 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;;;;;;;;;;; Creosote remover ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; monitor_event FactionTurnStart FactionIsLocal and not LosingMoney and Treasury > 10000 console_command add_money -1000 end_monitor monitor_event FactionTurnStart FactionIsLocal and not LosingMoney and Treasury > 20000 console_command add_money -3000 end_monitor monitor_event FactionTurnStart FactionIsLocal and not LosingMoney and Treasury > 30000 console_command add_money -6000 end_monitor while I_CompareCounter loop = 0 end_while end_script

At the beginning of each turn, the script will check the player’s treasury and then, if it above a certain amount and the player is not losing money, it will reduce it by the specified amount eg, 1,000 if it is above 10,000.

Note that all of these monitors will be triggered at the start of the player’s turn. Therefore if his treasury has gone higher than 30,000 he will not be docked 6,000 but 10,000 (1,000 + 3,000 + 6,000).

Here’s a very different script (from the late, unlamented Client Kingdoms 2 which will never be), one designed to give a non-player controlled faction a helping hand if things start going bad for them.

Code:

script declare_counter loop set_counter loop 0 monitor_event FactionTurnStart FactionType britons and I_NumberOfSettlements britons < 4 and RandomPercent < 15 console_command create_unit Londinium "warband sword briton" 1 console_command create_unit Londinium "warband hurler briton" 1 console_command create_unit Eburacum "warband sword briton" 1 console_command create_unit Eburacum "warband hurler briton" 1 console_command create_unit Deva "warband sword briton" 1 console_command create_unit Deva "warband hurler briton" 1 end_monitor while I_CompareCounter loop = 0 end_while end_script

Let’s take it step by step, first of all, the initial event:

Code:

monitor_event FactionTurnStart FactionType Britons and not FactionIsLocal and I_NumberOfSettlements britons < 4 and RandomPercent < 26

Means that it will be triggered when:
1) At the start of the Britons turn
2) When the player is _not_ playing the Britons
3) When the number of settlements the Britons own is less than 4
4) And if the computer picks a random number between 1 and 25 – this means that even when all the other conditions are satisfied it will only happen on average 1 time in 4.

If all those conditions are satisfied, then the game will run the script within the monitor, creating the units within those settlements. The problem with it at present is that script will create the unit its told to, irrespective of whether it is the Britons or another faction who control that settlement, and assign it to that faction which controls the settlement. We therefore need to check to make sure we only create the unit in a settlement if the Britons control that settlement, for example:

Code:

if I_SettlementOwner Londinium = britons console_command create_unit Londinium "warband sword briton" 1 console_command create_unit Londinium "warband hurler briton" 1 end_if

So our full script would look like the following:

Code:

script declare_counter loop set_counter loop 0 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;;;;;;;;;;;; britons in danger - Dads Army ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; monitor_event FactionTurnStart FactionType britons and I_NumberOfSettlements britons < 4 and RandomPercent < 15 if I_SettlementOwner Londinium = britons console_command create_unit Londinium "warband sword briton" 1 console_command create_unit Londinium "warband hurler briton" 1 end_if if I_SettlementOwner Eburacum = britons console_command create_unit Eburacum "warband sword briton" 1 console_command create_unit Eburacum "warband hurler briton" 1 end_if if I_SettlementOwner Deva = britons console_command create_unit Deva "warband sword briton" 1 console_command create_unit Deva "warband hurler briton" 1 end_if end_monitor while I_CompareCounter loop = 0 end_while end_script

Triggers

We’re now beginning to understand what a background script is, however the script is only one of the three elements listed in the Beginner Guide – we also need an advice thread and, more importantly, a trigger. These are done in the same way as in the Beginner Guide, so rather than go through them again, I’ll just show you an example.

The F1 trigger
This is the trigger used by Myrddraal in the first scripts that he released. It’s great benefit is that the trigger is not activated by normal play, it is therefore ideal for testing purposes and mods where the player can be relied upon to follow the process each time.

It is, in fact the exact same trigger that was used in the Beginner Guide. But here it is again
This is the advice thread (NB, all this already exists, only the Script line has been added)

Code:

;------------------------------------------ AdviceThread Help_Campaign_Keyboard_Shortcuts_Scroll_Thread GameArea Campaign Item Help_Campaign_Keyboard_Shortcuts_Scroll_Text_01 Uninhibitable Verbosity 0 Threshold 1 Attitude Normal Presentation Default Title Help_Campaign_Keyboard_Shortcuts_Scroll_Text_01_Title Script scripts\show_me\background_script.txt ; This is the added line Text Help_Campaign_Keyboard_Shortcuts_Scroll_Text_01_Text1 ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;------------------------------------------ Trigger 2137_Help_Campaign_Keyboard_Shortcuts_Scroll_Trigger WhenToTest ScrollAdviceRequested Condition ScrollAdviceRequested help_scroll AdviceThread Help_Campaign_Keyboard_Shortcuts_Scroll_Thread 0

To activate your background script (placed in the data\scripts\show_me folder, of course), you must press F1 – then click on the ? – then the advisor should pop up and you can click on the Show Me How button at the beginning of the campaign and after each reload.

Now more and more mods are developing background scripts, scripters have been looking into ways to make activation and reactivated more user friendly. Eventually, once a certain number of mods have been released, I imagine that a community standard will develop as mod-users become accustomed with a specific method. More sophisticated triggers (and their consequences) will be the topic of the further portion of this guide which will be a series of modules focusing on various advanced scripting techniques to which all are invited to contribute.

Re: An Intermediate Guide to Scripting

Quick question Richard

With use of script would that be possible to spawn mercenary unit for hire only for non-Roman factions (playable and non playable one) for example "Roman deserters".Obviously such a unit would not be available for Romans.Is that at all possible ?
11-28-2005, 11:46
Epistolary Richard

Re: An Intermediate Guide to Scripting

Yes, perfectly possible - but obviously not through the existing mercenary mechanism. Look at the Client Kingdoms mod for one way of doing it for the player. For non-player factions you would have to do it in a background script using a monitor_event with whatever conditionals you want and a create_unit console command inside.

Re: An Intermediate Guide to Scripting

a wonderful Thread...

I'm posting for very first time in this forum but i'm not reading in this section for first time...my english is not very good..please forgive me some grammar faults!
~:rolleyes:
A quick question:
has anybody checked the disable_ai console command if it works?
I would like to make a script that disable all the ai_actions and combine this with the faction switcher script! I have some problems with this matter because in the faction switcher script the ai make some stuff at the end of every turn...
i would like to execute this...

could it be that the command terminate_script? :stupido2:

here is the script:

HTML Code:

Thx for your reply Richard

Would something like this make any sens ?

HTML Code:

script if I_SettlementOwner Tarsus =(probably list of all non roman factions or is that another way ?) console_command create_unit Tarsus "merc roman deserters" 1 end_if end_script

Re: An Intermediate Guide to Scripting

pilatus I remember Myrddraal saying something about the disable_ai command when putting together the Hot Seat Mod. He certainly used halt_ai for that.

Maly Jacek If that's an event script then you're better off putting the conditionals in the trigger. If that's a background script you need a loop to keep it running and a monitor event in there to tell the game when to check the conditionals.

Re: An Intermediate Guide to Scripting

thx richard
but i've already checked the halt_ai command in myrdaals script and there is the problem that you can't make all factions playable at yourself..only two of them...if you make more the script says good bye!

I've also already checked the set_ai off command but i think this is only for the battle_ai...

has nobody checked the disable_ai command ?

Re: An Intermediate Guide to Scripting

Did the correct advisor speech bubble appear? The Show Me How button doesn't become available until the speech bubble appears.

Post the advice thread that you added the script line to in export_descr_advice.

Re: An Intermediate Guide to Scripting

Richard
As I have got not experience whatsover in scripting I have copy edited your your script:

HTML Code:

script declare_counter loop set_counter loop 0 monitor_event FactionTurnStart FactionType sassanids if I_SettlementOwner Dumatha = sassanids console_command create_unit Dumatha "merc cata" 1 console_command create_unit Dumatha "merc veteranii" 1 end_if if I_SettlementOwner Erewan = sassanids console_command create_unit Erewan "elite cata" 1 end_if terminate_monitor end_monitor while I_CompareCounter loop = 0 end_while end_script

That works but despite press F1 button it only works once.When I remove terminate_monitor I get new units created on every turn.Could you kindly tell me what line needs to be change for the unit to be created only upon pressing F1.I guess that could be also way of having message appearing advising player he can get new units.Also is there a line that could replace "Sassanids" with something like "all except Romans"

I solved the problem. If a script has any syntax error, the <show me how> button did not highlighted, not allows to run a script. Now my scripts run, but not wery well:(

script
declare_counter state
set_counter state 0
declare_counter loop
set_counter loop 0

console_command add_money -100; just for test to scripts really runs

monitor_event FactionTurnStart FactionType Egypt
and FactionIsLocal
and FactionHasAllies

if DiplomaticStanceFromFaction pontus >= Hostile
set_counter state 1
console_command add_money 2000; just for test to scripts really runs
end_if

if DiplomaticStanceFromFaction pontus < Hostile
set_counter state 0
console_command add_money -2000; just for test to scripts really runs
end_if

end_monitor

monitor_event FactionTurnStart EgyptFactionType Numidia
and not FactionIsLocal
and DiplomaticStanceFromFaction pontus <= Hostile
and I_CompareCounter state = 1

console_command diplomatic_stance numidia pontus war

end_monitor

while I_CompareCounter loop = 0
end_while

end_script

My allies is Nubidia. If I declare war with pontus I want to Nubidia declares war to. But the script not doing this.

Re: An Intermediate Guide to Scripting

If that is a direct copy&paste from your script then this line is part of the problem:

Code:

monitor_event FactionTurnStart EgyptFactionType Numidia

Then, there are the if lines in the first monitor.

Code:

monitor_event FactionTurnStart FactionType Egypt and FactionIsLocal and FactionHasAllies if DiplomaticStanceFromFaction pontus >= Hostile

DiplomaticStanceFromFaction requires exported parametres from a monitor, so it will no work if it is not tied to the monitor with ands. You'll have to split the monitor in two. This is how the other monitor should begin:

Code:

monitor_event FactionTurnStart FactionType Egypt and FactionIsLocal and FactionHasAllies and DiplomaticStanceFromFaction pontus >= Hostile

As a rule of thumb, if a condition doesn't start with I_ it requires to be used as an event monitor condition.

add_money <amount> <fraction name> not works.

Re: An Intermediate Guide to Scripting

From what other people have posted, you need a comma in there:

Re: An Intermediate Guide to Scripting

If I use spawn and move command to not local faction with monitor_event, hothing happaned:

script

and not FactionIsLocal
spawn_army
faction romans_julii
character Flavius Julius, general, command 0, influence 0, management 0, subterfuge 0, age 20, x 180, y 5
unit roman generals guard cavalry, soldiers 20 exp 9 armour 1 weapon_lvl 0
unit roman legionary first cohort ii, soldiers 40 exp 0 armour 0 weapon_lvl 0
unit roman legionary cohort ii, soldiers 60 exp 0 armour 0 weapon_lvl 0
unit roman praetorian cohort i, soldiers 60 exp 0 armour 0 weapon_lvl 0
end
console_command move_character Flavius Julius 170, 5
campaign_wait 1
console_command move_character Flavius Julius 160, 15
end_monitor
end_script

If I use it to not local faction without monitor_event spawn work, but no moves

If I use it to local faction spawn works, move works too.

Re: An Intermediate Guide to Scripting

Weird. Beats me why it doesn't work.

The only thing I can think of is that you were playing with the Julii when testing with not FactionIsLocal, but that wouldn't still explain why the moves didn't work..

Re: An Intermediate Guide to Scripting

You probably have the easiest way right there in your hands. If you don't need to check for specific factions there are a couple of conditions (OnWarFooting or similar), but for specific factions there's really no way around it. If you start doing these kind of repetitive scripts you should learn how to do script generators, with php, C++, excel or similar.

Re: An Intermediate Guide to Scripting

is it possible to have nested loops, if-statements and so on? could be a time saver in-game

pseudo-code:

Code:

if 1 if 2 [do something] end if ; 2 if 3 [do something] end if ; 3 while [something] [do something] end while end if ; 1

edit: I just realized it is ~D

another thing, for it to be a background script you have to add

Code:

while I_CompareCounter loop = 0 end_while

won't it go faster if you have

Code:

while I_CompareCounter loop = 0 campaign_wait 1 end_while

?

Well I don't think it would be noticable to be honest, but in theory yes :smile:

Is there a way to script senate-like missions?

I tried something like that some time ago.

One of the possible problems is to link the end of one mission with the beginning of the following one, and the method to test if that mission is feasible or not (for example if the corresponding region is still rebel, or it is owned by your own faction).
Any advance will be welcome.

Re: An Intermediate Guide to Scripting

Im just going to spawn a building in different provinces on the far reaches of the map to show which mission they are on, then use a monitor that will produce the appropriate mission when the building is spawned on completion of the previous mission, preventing old missions from running again.

Is there a way of counting how many turns have passed since a randomly generated event took place?

What about
and I_SettlementOwner <> Romans_Julii
?

Myrddraal worked out all the technical stuff, I just do the talking sloooowly with hand gestures bit. :bow:

But yes! Let us have some advanced scripting tutorials about the scripting in EB!
