Create units from external file list

[daryl]

Hi all,
can you help me please about this question:
i would like a script that create units from an external file list:

For example, I have this code:

Code: Select all

function gadget:GetInfo()
   return {
      name = "unita_iniziali",
      desc = "Aggiunge unità all'inizio del gioco.",
      author = " thx to http://springrts.com community"
      date = "September 19st,  2010",
      license = "GPL,  v.2,  2008",
      layer = 1,
      enabled = true,
   }
end
 
local gaiaTeamId        = Spring.GetGaiaTeamID()

eu_pilonax_a=Spring.CreateUnit("EUF_pilonax",3027,0,9301,2,3)
eu_pilonax_b=Spring.CreateUnit("EUF_pilonax",3582,0,9301,1,3)
eu_pilonax_c=Spring.CreateUnit("EUF_pilonax",3343,0,9656,1,3)
eu_pilonax_d=Spring.CreateUnit("EUF_pilonax",3582,0,9640,1,3)

end

this code create directly the units but,
I would like read the creating unit list from a file, example:

Code: Select all

function gadget:GetInfo()
   return {
      name = "unita_iniziali",
      desc = "Aggiunge unità all'inizio del gioco.",
      author = " thx to http://springrts.com community"
      date = "September 19st,  2010",
      license = "GPL,  v.2,  2008",
      layer = 1,
      enabled = true,
   }
end
 
local gaiaTeamId        = Spring.GetGaiaTeamID()

code that create units by reading the units list from "initialunits.lua"  ( or "initial.txt" or other file)

end

is this possible? can you help me to do this?
Thx you

Is a rather complex example of what you are asking for.

[zwzsg]

Unit creation is a synced operation (= must be the same on all computers in online game), and reading external files is disabled in synced context.

So you need to read the external file in unsynced gadget or widget, pass the data from unsynced to synced by using the special channels made for that, and then create units in a synced gadget.

Yes, it's much more convoluted than you'd expect.

But still possible, I've done it a long time ago viewtopic.php?f=44&t=24034
What I called loading savegame, and loading missions, is actually just about creating units from an external file.

Of course, during 6 years, Spring API probably changed enough that my code might not work anymore.

Not if it is a lua file inside the archive you include, zwzsg.

[daryl]

ok..Unit creation is a synced operation and.. what appen if I change this LUA code in all the computers in online game before playing?

for example I can edit directly this code:

Code: Select all

function gadget:GetInfo()
   return {
      name = "unita_iniziali",
      desc = "Aggiunge unità all'inizio del gioco.",
      author = " thx to http://springrts.com community"
      date = "September 19st,  2010",
      license = "GPL,  v.2,  2008",
      layer = 1,
      enabled = true,
   }
end
 


eu_pilonax_a=Spring.CreateUnit("EUF_pilonax",3027,0,9301,2,3)
eu_pilonax_b=Spring.CreateUnit("EUF_pilonax",3582,0,9301,1,3)
eu_pilonax_c=Spring.CreateUnit("EUF_pilonax",3343,0,9656,1,3)
eu_pilonax_d=Spring.CreateUnit("EUF_pilonax",3582,0,9640,1,3)
"x" other unit to player 2 etc...

end

this file will be edited before online play and this will be the same code in all the computer in online game.
Is this a good solution?

Not if it is a lua file inside the archive you include, zwzsg.

I interpreted "external" as "not in the game archive". Because as his first example indicate daryl already knows how to create units from a lua file inside the game archive.


Daryl: It might work, but no, it's not a good solution. The good solution is to use Spring.SendLuaRulesMsg & gadget:RecvLuaMsg to hop over the unsynced / synced great divide.

yes, as solution 1

ok.. i will do some experiments...
thx to all!!!

Ah. In that case you might consider some of the goodies in:
