Modding Q&A [For Quick Questions and Answers]

Ingame, i get an error called "unrecognized opcode", what is this? What does the game want to tell me with this?

That the opcode you feed it is not the right one.
Besides, there is something else in that error text besides "unrecognized opcode" string. Don't be shy, post error text in full

 

[Patta]

Yes, there is a number behind that, and something with a mission template trigger, the position of the error. I already figured that out, but because i don't really know what opcode means, i could not help myself It works fine, but i always get these errors.

edit: refers to this i think:

					(neq|le, ":team_1_living_players", 2),

Did not find a better solution, there is no "higher then" or is it?

Try:

(gt, ":team_1_living_players", 2),

Also, the error you got was due to a typo. You put neq, it should be neg.

 

[Patta]

ok, thx.

edit: seems like i start doing what many younger people in germany are already doing... putting a "q" instead of a "g"... Something i hate, normally...

 

[Caba`drin]

As an addendum to the above: the OPCODE refers to the number assigned a given operation in header_operations.
So, if you're getting a problem with OPCODE 1, there's an issue with your usage of "call_script" somewhere.

It should be :

(gt, ":team_1_living_players", 2),

For
le = neg | gt
neg = 0x80000000
gt = 32

so,
neg | le = neg | neg | gt = neg | gt = le

 

[Lumos]

neg | le = neg | neg | gt = neg | gt = le

Does my logic suck or I don't understand something?
Shouldn't it be:
neg | le = neg | neg | gt = gt
Shouldn't neg|neg be the same as negating a negation?

bool x = false;
x = false;
!x = true;
!!x = false;

 

[cmpxchg8b]

Nope, those are bitwise operations (they work on individual bits).
There is no negation, neg is just a value that gets bitwise-ored with others.

 

[Lumos]

Oh. Well, my bitwise operations definitely suck.
I thought they were ordinary logical operations.

Is it possible to use the tableau system to call different textures for the same mesh?  So that for example a byrnie would use a different 'fur' on it's cape depending on the banner of the owner? I don't mean just a different colour. (And I also don't mean that the banner itself would be  fur-patterned.)

 

[Sayd Ûthman]

I think it's possible if the banner is made from fur 

 

[FrisianDude]

Which is obviously not what I want.

Sure it's possible. Tableau material can use arbitrary tableau meshes, with different textures

I would like to make a Scene Prop that, on use, respawns all dead Players in the same team as the user. And it shall be somewhere close to the player using the scene prop. How can i best realize that?

 

[Sir Lacy]

And I have a quick question but it's a very mysterious quick question:

In #multiplayer scene names, in module_strings.py, there are 22 scenes, but only 18 in sceneobj folder and module_scenes / module_strings.py.

Maps like "The Arena" (scn_multi_scene_17.sco) and "Forest Hideout" (scn_multi_scene_18.sco) are referenced in strings as multi_scene_21 and 22 respectively, but they get their name displayed right ingame.

Is this some kind of hardcoded thing?

 

[Somebody]

Is this some kind of hardcoded thing?

No, if you look closely, the last 4 maps are randomized and require no SceneObj files. The strings are also in the same order as the scenes, so everything is working as expected.

(store_trigger_param_1, ":agent"),
(store_trigger_param_2, ":prop"),

#or however it is you set spawn position in multiplayer
(prop_instance_get_position, pos0, ":prop"),
(entry_point_set_position, 65, pos0),
(agent_get_team, ":team", ":agent"),

(get_max_players, ":num_players"),                               
(try_for_range, ":player_no", 0, ":num_players"),
  (neg|player_is_active, ":player_no"),
  (player_get_team_no, ":team_no", ":player_no"),
  (eq, ":team_no", ":team"),
  #stagger spawning position or something
  (player_spawn_new_agent, ":player_no", 65),
(try_end),

 

[Lord_Cheap]

Got a little question here:

Would it be possible to add a simple trigger to make sure that a lord and his liege will always be on good terms?
I think it should be easy to do but I'm not sure what operation to use. Thanks

 

[Somebody]

There is already one that degrades vassal-liege relations.

    #Individual lord political calculations
    #Check for lords without fiefs, auto-defections, etc
    (0.5,	
     [
...
(call_script, "script_troop_get_relation_with_troop", ":troop_no", ":faction_leader"),
(le, reg0, -75),

If you simply want to prevent them from defecting, change -75 to -300 or something or modify script_cf_troop_can_intrigue which gets checked afterwards. Otherwise, you can use (call_script, "script_troop_change_relation_with_troop", ":troop_no", ":faction_leader", value), before the relationship check.

If you make a banner dds, which has upto 21 different slides, and replace with 21 different fur slides (patterns, textures) your tableau mesh will have upto 21 different byrnie, I used this method to good use, in the heraldry of the Bretonnian knights,with the help of GKH

 

[FrisianDude]

Sorry for asking, but slides? As in layers or what do you mean?

Sure it's possible. Tableau material can use arbitrary tableau meshes, with different textures

Ahah, very interesting. Thanks both for the answers.
