Blueknights Questions

[blueknight1758]

It's come to my attention that I have lots of questions (I'm a noob) and it may seem that I'm 'spamming' the forums so I've create this thread for ALL my future questions thanks!

SOLVED

Question 1

How would you code an ability that reduces a units attack power (ranged and Melee) to one for a turn, like the 'slows' ability?

NEW

Question 2

Would it be possible to add a new attack type (pierce, impact etc) to the game?

[8680]

What do you mean by "attack power"? Damage? Strikes? Hit chance?

[blueknight1758]

I meant damage sorry.

[Dixie]

Correct me if I'm wrong: you want a weapon special (let's name it "superslow") that gives a special condition to units when it hits them, which make all of the target's attacks do only 1 damage? It's something a bit complicated, I hope you have at least an okay understanding of WML.

The main part of the code is derived from my Dazzle ability: http://forums.wesnoth.org/viewtopic.php?f=21&t=29544
The part that makes the attack do 1 damage is this: http://wiki.wesnoth.org/AbilitiesWML#Th ... als.5D_tag

Note that I haven,t tested it, but IIRC Dazzle worked, so you should have a relatively solid baseframe to work with. And by the way, it will only work in 1.9 because of the "side turn end" event which I use: it wasn't available under 1.8.

[blueknight1758]

I noticed dazzle that in your coding near the end it starts using 'dazzle' and 'undazzle' i assume that this is unitntentional and have changed them to superslowed for the version i am about to test and thanks for the code.

EDIT: once changed from dazzle to superslowed it works great! thank you!

[Dixie]

Yes, I notice I have forgotten the last post-advance event. You can also get rid of the two CLEAR_VARIABLE macro calls near the end - I've changed a few things in the code so that it behaves exactly like slow, and these call are obsolete. They won't cause the code to not work, though, they just do nothing

[8680]

Try this. Put {WEAPON_SPECIAL_ENERVATE} in the unit's attack's [specials] tag, and {ENERVATE_EVENT} in the [unit_type] tag.

Code: Select all

#define WEAPON_SPECIAL_ENERVATE
[dummy]
    id="enervate"
    name=_"enervate"
    name_inactive=_"enervate"
    description=_"A unit hit by this attack will have all its attacks' damages reduced to one for a turn."
    description_inactive=_"A unit hit by this attack will have all its attacks' damages reduced to one for a turn."
[/dummy]
#enddef
#define enervate_event_base evnm fltr uvar
[event]
    name="{evnm} hits"
    first_time_only=false
    [filter_{fltr}attack]
        special="enervate"
    [/filter_{fltr}attack]
    {FOREACH {uvar}.attack i}
        {VARIABLE _enervate_olddmg_[$i] ${uvar}.attack[$i].damage}
        {VARIABLE {uvar}.attack[$i].damage 1}
    {NEXT i}
    [unstore_unit]
        variable={uvar}
    [/unstore_unit]
    [event]
        name="side ${uvar}.side turn $($turn_number+1) end"
        [if]
            [have_unit]
                id=${uvar}.id
            [/have_unit]
            [then]
                [store_unit]
                    variable="_enervate_store_"
                    [filter]
                        id=${uvar}.id
                    [/filter]
                [/store_unit]
                {FOREACH _enervate_store_.attack i}
                    {VARIABLE _enervate_store_.attack[$i].damage $_enervate_olddmg_[$i]}
                {NEXT i}
                [unstore_unit]
                    variable="_enervate_store_"
                [/unstore_unit]
                {CLEAR_VARIABLE _enervate_store_}
            [/then]
        [/if]
        {CLEAR_VARIABLE _enervate_olddmg_}
    [/event]
[/event]
#enddef
#define ENERVATE_EVENT
{enervate_event_base attacker () second_unit}
{enervate_event_base defender second_ unit}
#enddef

edit : Too slow I guess.

Does that work? I tried that — in one of Blueknight's other threads I think — and Sapient said it didn't.

[Dixie]

Well it worked under 1.8 and up to about 1.9.2 or .3 (when I stopped actively doing code 'cause of school). I know some people frown at this method and it's nto referenced anywhere in the wiki, so maybe ti was deprecated or something. Although I still think it's pretty handy. But in any case, you could just define two macros - one for the actual weapon special, and the other for the events, and put the special where it ought to be and the events just outside of the attack tags... Or you could just include the events in an era tag, or in every scenario file, it's really up to you.

The avantage of the above method, as far as I'm concerned, is that I like having all related stuff in one spot. So if I want to meddle with my weapon special, I can just go to "specials.cfg" and I don,t have to look around unit files, the era file and some other random file. Then again, I s'pose you could just define a a macro for just the events and call it in the [era] or in every [scenario]. Oh well.

[blueknight1758]

Dixies code seems to work fine and I thank you for your help anyway 8680

[blueknight1758]

Would it be possible to add a new attack type (pierce, impact etc£

[powershot]

Would it be possible to add a new attack type (pierce, impact etc£

Yes, write a new one and it automatically works.

[blueknight1758]

where is the file you need to edit?

[Chtomorc]

It is the unit's files, check the wiki. Even if it is outdated, it give you the first steps to make new units.

[8680]

You mean a new damage type? Like, say, instead of having blade/pierce/impact/fire/cold/arcane you'd have blade/pierce/impact/fire/cold/arcane/antimatter? Put this in your campaign's #ifdef (I don't know how to do this in other add-on types):

Code: Select all

[+language]
    type_antimatter= _ "antimatter" # just using "antimatter" as an example
[/language]

Then you can use....

Code: Select all

[unit_type]
    ...
    [attack]
        ...
        type=antimatter
        ...
    [/attack]
    ...
[unit_type]

[8680]

Make sure to add his code or i will say ....... Type shadow, and will not give the right word:

....What?
