How is music changed during a fight once the first song is over? Is it possible to direct it to call a script or does it just automatically decide anything with mtf_sit_fight or whatever? Same with the world map.

Code: 
common_custom_siege_init = (
  0, 0, ti_once, [],
  [
    (assign, "$g_battle_result", 0),
    (call_script, "script_music_set_situation_with_culture", mtf_sit_siege),
    ])

common_siege_init = (
  0, 0, ti_once, [],
  [
    (assign,"$g_battle_won",0),
    (assign,"$defender_reinforcement_stage",0),
    (assign,"$attacker_reinforcement_stage",0),
    (call_script, "script_music_set_situation_with_culture", mtf_sit_siege),
    ])

common_music_situation_update = (
  30, 0, 0, [],
  [
    (call_script, "script_combat_music_set_situation_with_culture"),
    ])

update the situation and call the script to change music (like if you are about to lose, etc)

when you win:
Code: 
              # script_play_victorious_sound
              # Input: none
              # Output: none
              ("play_victorious_sound",
                [
                  (call_script, "script_music_set_situation_with_culture", mtf_sit_victorious),

Hello all, a question from amateur modder here...

I'm trying to make a check if player has horses (any kind of horse will do), then this menu appears. But it doesn't seem to detect it. I took example from food check script (check if there is food, if there's any, consume). Can I ask for help?

It's in game_menus.py

Code: 
("camp_action_do_the_horse",0,
   "Placeholder text: thing of another later",
   "none",
   [],
    [
	("action_do_the_horse",[
						(try_for_range, ":cur_horse", horses_begin, horses_end),
						  (player_has_item, ":cur_horse"),
						(try_end),
                             ],"Check horse condition.",
       [
		  (display_message, "@Test"),
        ]
    ),

Also is there a way to show a number of horses the player have? E.g. the menu will show as "Check horse condition (you have 10 horses)".
 
You don't set anything in that try-for-range loop. You loop through horses and check, the check passes or fails, and then .... nothing happens. You need to toss a variable in there that gets checked, something like:
Code: 
	("action_do_the_horse",[
					(assign, ":has_horse", 0),	
                                        (try_for_range, ":cur_horse", horses_begin, horses_end),
						  (player_has_item, ":cur_horse"),
                                                  (assign, ":has_horse", 1),
					(try_end),
                                        (eq, ":has_horse", 1),
                             ],"Check horse condition.",
 
Oooh, so that's what the variable is used for. Thanks Caba'drin!

The other question, can I count how many horses player have inside the (try_for_range) loop? I find (store_item_kind_count), but it seems it doesn't count all horses collectively? (so it only counts 3 Courser, 1 Steppe Horse, etc)

I need a guide for simple destructible walls for AoFI's cannons. I've made that, but it is not working;

		(try_end),

Code: 
destructible_init = (ti_on_init_scene_prop,
 [

(assign, ":wall_instance", 1),
(assign, ":wall_hitpoints", wall_health),
 
 (call_script, "script_destructible_wall_init", ":wall_instance", ":wall_hitpoints"),
 
 ])

(assign, ":wall_instance", 1),
(assign, ":damage", 1),
 (call_script, "script_destructible_wall_damage_receive", ":projectile_instance", ":wall_instance", ":damage"),
 
 ])

In the game, there is no errors and positive result. Where's my fault ?

Also, assigning the variables on wall_damage_system was necessary, it was giving unassigned local variable warning.

Any ideas on this ?

Local variables persist through try_blocks, so use one of those. A val_add operation can be used to count the number of entities that fit a given criteria by adding 1 to the variable whenever those criteria are met.
 
I have a question for anyone that fiddles with Multiplayer.

I didn't even touch the banners since the last version, yet this problem started to happen:

For both factions. Something's noticeable at the edges of the banner...if anyone had this before any help is appreciated.

that would work, but it is like taking a trip to the moon when all you want is to cross the street.
Use Caba's snippet, change the assign to a sum (val_add) and you will have your horse count

you should read the basic tutorial/guides on modding and syntax:  :arrow: http://forums.taleworlds.com/index.php/topic,240255.0.html
 
Hi.
To make work the operations added with patch 1.165 on dedicated server, do i need to use dedicated server files for version 1.165 ? Now i use version 1.158.
Module presentations isn't loaded by dedicated servers, right ?
Thanks.
 
dedicated servers probably do need to have the presentations.txt files, but you can remove all presentations from it, leaving just the hardcoded ones, cause it wont use any

_reinforcement_ globals and this operation
Code: 
add_reinforcements_to_entry

you can see it be used on mission_templates like "lead_charge" and remove this altogether. Remember to reconsider battle advantage if you won`t let them get more troops, otherwise your battles will end up being too easy

Hello!

How does one add new races? I appear to have completely forgotten how.

**EDIT**

Nevermind, it has all come back to me now.

**EDIT 2**

Now I need help making them playable, some help would be very appreciated.
 
I'm trying to set up a Module System and Python to mod M&B Warband and have a noob question or two:

Will Module System version 1.165 work with M&B Warband version 1.168? Or do I need to find an older version of the game? (As I haven't found any newer versions of the Module System)

I figure any Python version older than 3x is good? (like 2x something).

You can use 1.165 modules, but download Lav's version 1.166 instead: http://forums.taleworlds.com/index.php/topic,324874.0.html. It has better documentation, it will make your modding life much easier
