Volcano terrain

[VulcanScout]

Hi,

I have a problem with the volcano sprites.
https://freeciv.fandom.com/wiki/NEWS-3. ... %20amplio2
I add the volcano sprites from the 'volcano.spec' in the amplio2 directory,
to my game.

The volcano should appear as:

volcano.png (7.08 KiB) Viewed 536 times

In 'terrain.ruleset'

Code: Select all

[terrain_volcano]
name                 = _("Volcano")
graphic              = "volcano"
graphic_alt          = "mountains"
…

The game is stubborn though, it gives me the image for mountains. I add the
image a single sprite to the game.

Code: Select all

[extra]
sprites = {
  "t.volcano", "modernized/terrain/volcano"
}

Result

I try because the volcano would be a nice addition to the terrain, it’s a
better requirement for a wonder in my ruleset than mountains.

In 'buildings.ruleset'

Code: Select all

[building_pompeii_site]
name    = _("Pompeii")
reqs    = {
  "type", "name", "range"
  "Tech", "Archaeology", "Player"
;  "Terrain", "Volcano", "City"
; Volcano is commented out, because the sprite doesn’t work correctly,
; use mountains instead.
  "Terrain", "Mountains", "City"
}
…
