[solved]Help wanted! Unhide a technologie, so it can be researched afterwarts, in existing game

[Kupferdrache]

I am migrating so stuff and used the recommend methode, but I get a wrong script usage anyway.

Code: Select all

61.504 Warning Scenario.cpp:227: Map loading failed during migrations processing: Error while applying migration: Angel's Processing: angelsprocessing_0.2.2.lua

Cannot execute command. Error: Trying to research technology when the game isn't even initialised. (Wrong script usage)
stack traceback:
	[string "game.reload_script()
..."]:62: in main chunk

here is the code snippet, that causes the error:

Code: Select all

if force.recipes["ore-processing-plant-2"].enabled then
	force.technologies["bio-processing-1"].researched = true
	force.technologies["bio-processing-2"].researched = true
end

May be you can help me to fix that thing.

Edit I changed the title, now that I know that z groups messed my save up, I could restrat, but I like my map, and i don't want to rebuild my factory if at all posible.

[aubergine18]

Which file do you have that code in?

Read: http://lua-api.factorio.com/latest/Data-Lifecycle.html

[Kupferdrache]

it is in /modfolder/migration/modname_<actual version>.lua The place where it belongs to. As far as i know, as it only has to run once. I shall activate two technologies, that are hidden for some reson. and I can't find the source of the hiding. If I start a new game with all updated mods, the two technoligies are available to research.

Cam somebody point me to a better way to unhide the technolgies? tell me If you need the foll modlist to do that.

[Nexela]

Is that everything in the migration file? If not it might be worth posting the whole contents of the file.

Here is the complete file:

You can find the whole mod in the unoffical patches under: posting.php?mode=reply&f=120&t=33603#pr211519

[Kupferdrache]

As this seems to be a cross mod issue in my case I got the Idea to fix it after migration with help of the control.lua. So I write a patch for the mod, the config got changed after world creation, and that presumingly hides the techs, I now want to unhide together with some recipes, that I don't want to be hidden, but I had to figure this setting out while playing, so changing after creation without reseting the map process is nessecary.

Unfornately, the on_configuration_changed() is not so well documented that I can figure out, how to use it for my case.

If you can help me, take a look on my work so far, be warned it is not much yet.

the currend version is now bug free for transition. new features and bug fixes will wander in a 1.2.7 version.

[Kupferdrache]

I found found something in the lua api, but I am not sure how to use it.

Could somebody tell me via exsample if posible, How to us this scripts (situation, synatx, places, limitations)? I am especially interested in use of these in a /migrations/[...].lua or as function of on_configuration_change inside of control.lua .

Code: Select all

class LuaForce
disable_research()	Disable research for this force.
enable_research()	Enable research for this force.
disable_all_prototypes()	Disable all recipes and technologies.
reset_recipes()	Load the original version of all recipes from the prototypes. // this seems to be one of the recomended one for migartion scripts to use
enable_all_recipes()	Unlock all recipes.
enable_all_technologies()	Unlock all technologies.
research_all_technologies()	Research all technologies.
reset_technologies()	Load the original versions of technologies from prototypes. // this seems to be other one of the migration script ones, that is recomended to use
reset()	Reset everything.

I hope with your help I can figure out, how to get access to hidden recipes back, so I can craft them in assemly maschine.

[Kupferdrache]

Now I know, I should be able to unhide the technologies on update via contraol.lua and a on.config_changed() function. But I still haveb#t figured out what to do excatly. Would be nice, if someone could help me with that part.

[Nexela]

First the primer http://lua-api.factorio.com/latest/Data-Lifecycle.html

script.on_init() -- Called once, and only once the first time a mod is installed.
script.on_configuration_changed() -- Called every time an mod is added/removed/has_version_changed. EXCEPT on first install when on_init is called in a NEW game

Migration files are only ran ONCE (for each migration file) and are marked as installed internally. I also don't think migrations are run when a mod is added to a new world but I could be wrong.


script.on_configuration_changed would take the exact same syntax as the migration.lua file. just remember that it is ran (once) every time a mod or mods is/are added/removed/updated (including factorio versions)
I don't believe game.reload_script() is needed though

Code: Select all

script.on_configuration_changed(function() 
for index, force in pairs(game.forces) do
  force.reset_technologies()
  force.reset_recipes()

if force.technologies["bio-processing-1"].researched then
    force.recipes["cellulose-fiber-raw-wood"].enabled = true
   force.recipes["wood-from-cellulose-resin"].enabled = true
   force.recipes["water-mineralized"].enabled = true
end
end)

Alternativly you could do: (syntax may not be %100 accurate)

Code: Select all

script.on_configuration_changed(function (data)
if data.mod_changes["name-of-trouble-making-mod-always-re-hiding-stuff"] then
  run the for loops code from above here
end
end)

[Kupferdrache]

Thanks for your help, unfortantly your code doesn't work. I get following Error:
[quote=factorio-output]__ZGroupChange__/control.lua:10: unexpected symbol near ')' [/quote]

And i have another issue, it works for recipes, but my problem is missing Technologies.

And yes, i have the Data-Lifecycle open, but i doesn't help me to track down the code to reverse the tech hiding.

[aubergine18]

Do you have a linter installed? If not, it will help you find the syntax errors as you make changes to scripts (much faster than having to keep restarting game over and over): viewtopic.php?f=34&t=29919

[Nexela]

Add another "end" above one the "ends" (I highly recommend an editor or IDE that supports lua error checking to easily catch stuff like this Zerobrane Studio *FREE* I believe supports error checking out of the box with no complicated windows linter setup)

I guess it depends on What angel is doing to the technologies, If he is just un-enabling them then something like this might work for your technology problem syntax accuracy not guaranteed cause its 5 am here.

script.on_configuration_changed(function ()
for _, force in pairs(game.forces)
force.technologies["TECH-NAME"].enabled=true
--more code here.
end
end)

Still boils down to what exactly Angel is doing and the best course of action may be asking him. or looking through his code.

[Kupferdrache]

I installed ST3 and the linter, it has better syntax highlighting than my normal used editor, but I am not sure if the linter works.

[Nexela]

I believe you have to have Lua and Luacheck installed on your computer. and with ST3 I "think" the base linter app and linter-luacheck or some such.

[Kupferdrache]

I added a check, so it only enables the techs if they are missing, unfortately checking for enabled = false seems not to be posible.

here the currend code:

Code: Select all

--luacheck: globals defines game global script
script.on_configuration_changed(function()
for _, force in pairs(game.forces) do
  if force.technologies["bio-processing-1"].disabled then
    force.technologies["bio-processing-1"].enabled = true
  end
  if force.technologies["bio-processing-2"].disabled then
    force.technologies["bio-processing-2"].enabled = true
  end
  if force.technologies["electronics-machine-1"].disabled then
    force.technologies["electronics-machine-1"].enabled = true
  end
  if force.technologies["electronics-machine-2"].disabled then
    force.technologies["electronics-machine-2"].enabled = true
  end
  if force.technologies["electronics-machine-3"].disabled then
    force.technologies["electronics-machine-3"].enabled = true
  end
end

for _, force in pairs(game.forces) do
  force.reset_technologies()
  force.reset_recipes()

if force.technologies["alloy-processing-1"].researched then
  force.recipes["bronze-pipe"].enabled = true
  force.recipes["bronze-pipe-to-ground"].enabled = true
end

if force.technologies["plastics"].researched then
  force.recipes["plastic-pipe"].enabled = true
  force.recipes["plastic-pipe-to-ground"].enabled = true
end

if force.technologies["zinc-processing"].researched then
  force.recipes["bronze-pipe"].enabled = true
  force.recipes["bronze-pipe-to-ground"].enabled = true
end

end

end)

Anyone an idea how to make it better? As lua technology doesn't contain the key disabled.

[Nexela]

If you check the LuaTechnology API you will notice there is not a .disabled method/var .To check if something is disabled you check if .enabled (a boolean that is R(ead)/(W)rite meaning you can read it and/or change it) is false

if force.techologies["whatever"].enabled = false then --do whatever here end

This is also the same as doing

if not force.technologies["whatever"].enabled then -- not enabled do stuff here end

[Kupferdrache]

I tested checking for .enabled = false, you can't do it, you get a error on load, but if not should work.

[Nexela]

I tested checking for .enabled = false, you can't do it, you get a error on load, but if not should work.

What exactly is the error?

[Kupferdrache]

something about, expecting the then after .enabled, if you add the ' = false ' between '.enabled' and 'then'. I don't have the error mesage on hand anymore. But, annding not worked, now I can undate the unoffical mods, for thatversion a last time, as there shold be no critial errors remaining for other to try out.
