Summon unit on death

[Spitoven]

Hello

I'm trying to make all units with a certain trait summon a specific unit when they die, like their soul is going out of their body to continue fighting. So it would be just like Plague but not depending on what weapon delivered the killing blow and with the summoned unit being on the same side than the killed unit

My main problem is that I can't find how to apply filters that recognize the dying unit. And it looks like you can't use events with traits and I'm unsure of how to proceed with a custom function. Yet I guess a code which would work for both traits and abilities would be more usefull to the community

Can you help me please

Ooooh thank you

I only have one more question: What happens with this code when an unit with this summon-on-death ability is killed by an unit with Plague? Which one takes precedence?

[Ravana]

Should be event because of [kill].

[Spitoven]

Oh, ok! I want Plague to take precedence. So I added a filter but... it doesn't work

Code: Select all

        [filter_second]
            [filter_weapon]
                [not]
                    special_id_active=plague
                [/not]
            [/filter_weapon]
        [/filter_second]

What did I do wrong

What did I do wrong

[filter] (and [filter_second], for that matter) doesn't support [filter_weapon] inside itself; instead, it uses [has_attack]. Here's a list of what's allowed in unit filters: https://wiki.wesnoth.org/StandardUnitFilter.

Thank you! So I changed the code

Code: Select all

        [filter_second]
            [has_attack]
                [not]
                    special_id_active=plague
                [/not]
            [/has_attack]
        [/filter_second]

But with this filter on the unit I wanted to summon never shows up anymore, even when the enemy doesn't have plague! How?

[Ravana]

special_id_active might not work as you expect. First get it working with special= instead.

Instead of filter_second->has_attack you can use [filter_second_weapon].

[Spitoven]

Thanks! So now the code is

Code: Select all

        [filter_second_weapon]
            [not]
                special=plague
            [/not]
        [/filter_second_weapon]

But now, whether the enemy has plague or not, my unit just gets summoned anyway again (and same result if I still rather use special_id_active=plague)
What's wrong with this damn plague

[Ravana]

Actually filter_second_attack not filter_second_weapon.

[Spitoven]

Oh, thank you it... WORKS! At last

But there's still a problem, right? I guess "special=plague" will prevent the summoning even if the dying unit is unplageable. So I added this:

Code: Select all

        [filter]
            [not]
                status=unplagueable
            [/not]
        [/filter]

...and I duplicated the event, in which I reversed this last filter and removed the other one. Should work right?

[Spitoven]

Yes it works! Thank you very much to you both
