EarthCake's problems

Thanks!

Unmounting units:
I have few loyal mounted units, and I want to make them "ground" units on same tile when they lose all hp. In example, if they are horsemen, I want to make them spearmans, but to make them keep xp. Same as knight -> Pikeman. Is that possible?

[Ravana]

Yes.

Either die event and create new unit based on old one, or last breath and change old unit into new unit.

[josteph]

Note that Knight max_xp > Pikeman max_xp, so it's possible for the dying Knight to have more experience than Pikeman's max_XP.

[EarthCake]

How do I make them keep the same name, traits, and to appear at same tile?

[josteph]

Use transform_unit.

Code: Select all

                [unit]
                    type=Pikeman
                    name=$unit.name
                    x,y=$x1,$y1
                    # The unit has almost been killed, so assume they start with no moves. Might also want attacks=0.
                    moves=0
                    side=$unit.side
                    experience=$unit.experience
                    # having animate=yes will make the unit appear as if it was recruited, see if it looks right
                    animate=yes
                [/unit]

Copying the traits can be done as in this code from SotA. The SotA code also has loads of other stuff which you probably won't want, but is a handy list of edge-cases.

There us some problem with lua:

Code: Select all

<Lua error>
	game_error: creating unit with an empty type field
	stack traceback:

		lua/wml-utils.lua:145: in field 'handle_event_commands'

Here is code for "Unmounting.cfg":

Use transform_unit.

That only transforms horseman into next level and then kills him (but very probably I screwed something with the code).

What are the values of $horseman and $cavalryman just before the [unit] tags start?

[EarthCake]

What are the values of $horseman and $cavalryman just before the [unit] tags start?

$horseman = Spearman
$cavalryman = Swordsman

Code: Select all

			[set_variable]
				name=cavalryman
				value=Swordsman
			[/set_variable]

Code: Select all

			[set_variable]
				name=horseman
				value=Spearman
			[/set_variable]

[Pentarctagon]

$horseman = Spearman
$cavalryman = Swordsman

Code: Select all

			[set_variable]
				name=cavalryman
				value=Swordsman
			[/set_variable]

Code: Select all

			[set_variable]
				name=horseman
				value=Spearman
			[/set_variable]

And it prints that if you add:

Code: Select all

[message]
	message=$cavalryman
[/message]
[message]
	message=$horseman
[/message]

?

[Ravana]

Those tags are not reached, so both variables are undefined.

Also, while this might work but it looks dodgy.

Code: Select all

[set_variables]
		name=unmounting
		mode=replace
		to_variable=unit
	[/set_variables]

[EarthCake]

Ah, value needs to be Horseman and Cavalryman ?

About code mentioned up, I copied that from SotA (thanks octalot!) and it works there.

[josteph]

You're comparing unmounting.id to "Horseman", that's never going to be equal. You meant to compare unmounting.type.

[josteph]

Use transform_unit.

That only transforms horseman into next level and then kills him (but very probably I screwed something with the code).

I assumed you had already solved the "prevent the unit from dying when it reaches 0HP" part and was asking only about the "change the unit's type preserving its other attributes" part.

In any case, a last breath event that does [modify_unit] hitpoints=... would prevent the unit from dying, after that you can do [transform_unit] to change its type.
