Lua Script

Hi,
The image is a piece of my scenario (attached)
I would like to create two scripts: one for the red line and another for black line. The idea behind black line is a sort of mission. I've tried to create a script, but it doesn't run. The summary: an UNIT (i.e. Phalanx) move from POINT A to POINT B, when UNIT arrive to POINT B, the PLAYER or NATION gets 2000 gold and a line in chat with ''Mission Complete''. This script is ''high-potential'', especially for tutorial.sav.
Code: Select all
function has_unit_type_name(unit, utype_name)
return (unit.utype.id == find.unit_type(utype_name).id)
end
function unit_moved_callback(unit, src_tile, dst_tile)
local beta = find.tile(178,192)
local owner = find.player(0)
local type = find.unit_type('Phalanx')
if unit.owner:is_human() then
if unit_type == type then
if dst_tile.tile == beta then
change_gold(owner, 2000)
notify.player(unit.owner, [[Mission complete!]])
end
end
end
end
signal.connect('unit_moved', 'unit_moved_callback')
The second script, red line... eh, I haven't any idea about the structure. The idea is: fixate an easy target (enemy) like conquer a city. In example: I play with French, I would like to fixate as target (for English) to conquer my city (Wimereux) or move their troops close a specific coordinate (on the other side of English Channel).
Details
greatbritainv2.5.sav.gz:
- 6 nations (English, Scottish, Welsh, Irish, French and Manx)
- map size 350x350 (122'500 tiles)
- 58 cities (English)
- 20 cities (Scottish)
- 15 cities (Manx)
- 13 cities (Irish)
- 11 cities (French)
- 07 cities (Welsh)
- 124 cities total

if unit.owner:is_human() then
if unit_type == type then
if dst_tile.tile == beta then
Does this work?
if unit.owner:is_human() then
if has_unit_type_name(unit,'Phalanx') then
if dst_tile.id == beta.id then

Yes! Thank you very much

I would like to reward
only the units from a specific city. Now the script rewards every unit. I have to insert ''src_tile'' parameter in the script to define the city, but I don't know how to do.
Code: Select all
function unit_moved_callback(unit, src_tile, dst_tile)
local origin = find.tile(321,336) --Wissant (France) ORIGIN CITY
local beta = find.tile(326,333) --Calais (France) DESTINATION CITY
local owner = find.player(0)
if unit.owner:is_human() then
if has_unit_type_name(unit,'Warriors') then
if src_tile.id == origin.id and dst_tile.id == beta.id then --INSERT SCR_TILE PARAMETER
change_gold(owner, 500)
notify.player(unit.owner, [[Mission complete!]])
end
end
end
end
It doesn't run.

Did you try unit:get_homecity() ?

Yes, it works!
There is a lua function: edit.create_road(tile, name). Now, I would like to create a road from POINT A to POINT B. My attempt:
Code: Select all
function distance_between(x1, y1, x2, y2)
local hdist = math.abs(x1 - x2)
local vdist = math.abs(y1 - y2)
return math.max(hdist, vdist + math.floor(hdist / 2))
end
local ATTEMPT = print(distance_between(10, 20, 10, 70):sq_distance
edit.create_road(ATTEMPT, 'Road')
Under ''Type Tile'' I've found:
(Tile):sq_distance, but I don't know how to do. Maybe it's the correct parameter.

Is there any possibility to load an image with lua script in notify module? I've searched on the code about ''message'' parameter in notify and I've found:
const char *message. This constant is connected (I think) to send_chat. Now.. Is there any possibility to add at ''send_chat'' a markup language for
bold,
italic,
underline, image, ecc.? I've read
http://gna.org/patch/?3361, but I don't know if helptexts is connected to ''message'' in notify.

I'm not entirely sure if "featured text" is passed that way, but have you tested that text with markup doesn't work there already? There's no support for image but only text modifications such as bold, italic, underline, color, and making links to units, cities, or tiles - see "Chat tools" in gtk-clients (opened by clicking button next to chat-line)

Yes, there are text modifications in Chat tools, but these (tags ie. b, u, etc.) don't work in Lua script (notify module).
Script:
Code: Select all
function turn_callback(turn, year)
if turn == 0 then
notify.event(nil, nil, E.SCRIPT,
_("[b]Welcome to Freeciv[/b]. You lead a civilization. Your\n\
task is [i]to conquer the world[/i]! You should start by\n\
exploring the [u]land around you with your explorer[/u],\n\
and using your settlers to find a good place to build\n\
a city. Use the number pad to move units around."))
end
end
signal.connect('turn_started', 'turn_callback')
Output:
notify.png

Actually, it's the popup where they don't work. They're parsed, as you can see from the fact that tags are not displayed literally, but only the chat window has ability to show them.
