Add new recruitable unit with an object

[lhybrideur]

Hi everyone,
here is what I am trying to do.
I want to have one object on the map that when picked up allows the side to recruit a new unit type.
Here is what I would like to do:

Code: Select all

[object]
	name= _ "Intuitive Encyclopedia of Elementals"
	[effect]
		apply_to=???
		[allow_recruit]
			side=unit.side
			type=Vine Beast
		[/allow_recruit
	[/effect]
[/object]

Here is what I am currently doing (not tested)

Code: Select all

[object]
	name= _ "Intuitive Encyclopedia of Elementals"
	[effect]
		apply_to=new_ability
		[abilities]
			{ABILITY_BEGINNER_ELEMENTALIST}
		[/abilities]
	[/effect]
	description="Allow to recruit Vine Beasts"
[/object]
#define ABILITY_BEGINNER_ELEMENTALIST
[dummy]
	id=beginner_elementalist
	name= _ "beginner elementalist"
	description= _ "Allow to recruit Vine Beasts."
[/dummy]
#enddef
[event]
	name=turn refresh
	first_time_only=no
	[allow_recruit]
		[has_unit]
			ability=beginner_elementalist
		[/has_unit]
		type=Vine Beast
	[/allow_recruit]
[/event]

Do you have anything more simple that what I am currently doing?

EDIT: corrected the event. It is now working

just using `[allow_recruit]` if gotten item. Unless you want to this to be just temporary (as in, would go away if you lose this unit)

Is the idea that this book is an item that can be lost, or even given to another unit?

If so, I think the best approach would be to use a custom effect that gives the unit canrecruit=yes and extra_recruit=Vine Beast. You need some Lua setup to support it, but your WML would end up looking something like this:

Code: Select all

[object]
	name= _ "Intuitive Encyclopedia of Elementals"
	[effect]
		apply_to=allow_recruit
		type=Vine Beast
	[/effect]
[/object]

Basing it on extra_recruit means the unit who has the book would need to stand on a keep in order to recruit a Vine Beast. It'll also be able to recruit any other units that the side can recruit, though, which may be undesirable?

Code: Select all

[object]
	name= _ "Intuitive Encyclopedia of Elementals"
[/object]
[allow_recruit]
	side=$unit.side
	type=Vine Beast
[/allow_recruit

[object] to show message, but [allow_recruit] is usual actionWML and should not be inside.

Thank to all of you for your answers

I am not sure if it is what you meant, but I think using

Code: Select all

[object]
	name= _ "Intuitive Encyclopedia of Elementals"
	[then]
		[allow_recruit]
			side=1
			type=Vine Beast
		[/allow_recruit]
	[/then]
	description="Allow to recruit Vine Beasts"
[/object]

should work.
I will try that asap.

If my idea does not work, I would like to try yours, but I have no idea how to write that in lua. Do you know if there is an example of custom apply_to in a campaign?

EDIT: my bit of code seems to work

To be clear, this is an example of a custom apply_to written in Lua. There are also several examples in the effects.lua file, which is also part of World Conquest.
