Wiki tutorial by FreeER

[WovenCookie]

i was doing the tutorial and typing it but then a error came up, so i decided i will just copy paste but the error still came up

it said
Factorio\mods\Solar-Plus|data.lua:21:' } ' expected (to close ' { ' at line 1) near ' { '

and its the same code from the wiki, i didnt change anything yet.
im using notepad++ if that makes a difference...

[FreeER]

Hm, without actually seeing the code then I can't really point out the problem any better than the error message does, which is that Factorio expected a table that started on line 1 to end on line 21 with a '}' but it didn't (notepad++ shows ')'s and 'end's as equivalent to '}' but they truly aren't, they must match what opened them). It could be that a '{' was typed accidentally instead of a '}', or it could also be that it shouldn't be ending on line 21 but does because it's missing a ',' which is what it looks for to tell when a table 'should' end... It is entirely possible that the wiki has a mistake, it is also possible that the mistake is a bit higher up in your code than where you copied from the wiki... I just can't tell without seeing the code

[WovenCookie]

Sorry for the miss understanding, i didn't put in my code yet, i just wanted to see an example its the same exact code from the wiki. I added the commas and that helped but it now says

Error while loading prototype"bomber": Energy amount has to be specified in W or J (Watts or Joules)

so, yeah i tried to find the energy input in the code but i couldn't find it, so I'm just clueless.
i only went to chapter 6 btw, could that be the problem?

no, no that one actually is a problem with the wiki code Not a 'direct' problem, as in I did it wrong mind you (but it hasn't been updated in awhile) Factorio now requires the 'consumption' property of the car to be a string of "_number_measurement", meaning something like "600kw" (that's what the base game has for the car). So change consumption from 0.1 to "6kW" with the quotes (I believe that would be the appropriate conversion...it used to be per tick which is 60 times per second so a multiplication of 60 and tacking on the kw should be right). When encountering any issues loading prototypes ("x has to be specified in y", "could not load x", "x missing for y", etc.) it's best and easiest to check how that type is defined in the base game (Factorio\data\base\prototypes) since the base will always be up to date I see a few things that are also 'new' to the car prototype, but mostly sound related (so I don't think those will be required for the bomber...)

A tip when using Notepad++ is that you can right click a tab and select 'move to other view' and you can see two tabs at once (and if you have the 'compare' plugin installed, I think it is by default, you can click plugins->compare->compare or press alt+d, and ctrl+alt+d to clear the results. Clearing the results seems to 'reset' the the language selection though so you have to go to the top of the file and make any change to 'fix' it).

btw, sorry for the delay in responding.. I got distracted playing the Son of Nor beta

[WovenCookie]

Wow, i don't know what it is, every time i fix one error another comes up, do you think at this point i should just go from scratch? any way here is the error, this error looks simple but i am just a beginner and only has a slightest clue of what I'm doing


EntityPrototype Unknown key:"entity-name.bomber" doesn't have an order string.

oh and thanks for your patience this stuff is helping me out more than you might think.

[FreeER]

entityPrototype Unknown key:"entity-name.bomber" doesn't have an order string.

ah, another change since I made the tutorial... add [order = "something"] to the bomber, like was given to the items, it can even be the same string (without the '[]', I just needed a way to deliminate it since I was already using quotes). It's used to determine the order of items in the inventory (alphabetically).

oh and thanks for your patience this stuff is helping me out more than you might think.

No problem, I enjoy helping, plus it's sort of my fault for not updating the tutorial

[WovenCookie]

add[order = "something"]

did you literally mean "something" or just put something there either or it still showed the same error when i did it.

edit: Nevermind i fixed it,i didnt add

place_result = "bomber",

well i think thats it... i just need some pics and im good to go

[Rahjital]

Something is whatever you want. Here is the order string used by the big biters:

Code: Select all

order="b-b-c"

Also note that if the entity you created can be placed by an item, it does not need an order string of its own because it inherits the one in the item prototype.

[Stoner]

I followed this guide step by step but the mod doesn't work. When I start factorio an error pop up telling : "Error while loading entity prototype "bomber" (car): No such noce (animation).

[Pure_beam]

When ever i try launching my game with my mod in, it keeps giving me this error " Error while loading entity prototype "bomber" (car): No such node (animation) " i have only done chapters 1-4, but i have not gotten to open my game up to test the bomber because of this, i have followed exactly, copy and paste, i am running factorio 11.3 thanks great tutorial, very easy to follow, seems to be a decent amount of support, and i can see this helping people make some great mods

This guide is for version 0.10.3, can edit car entity with base-game car

An updated version of this tutorial would be very much appreciated, then. That, or an explanation of what you mean with this?

An updated version of this tutorial would be very much appreciated, then. That, or an explanation of what you mean with this?

An updated version is on the way, I just haven't managed to take the time to rework the graphics for the bomber into the new manner used by the car entity. by "edit car entity with base-game car" L0771 meant that you can overwrite the bomber entity in the tutorial (which is based off of the car entity type) with the car entity in the base game which is in the /data/base/prototypes/entity/entities.lua file (search for "car"). Here's a partial update (with that change, might even work in MP), obviously no nice bomber graphics in game.
edit: as for the tutorial itself I've made a few notes for updating it (rough and near useless for learning as they are but might as well share them as well)

notes

note when zipping: internal folder does not NEED to be 'correct'
but it is recommended so the mod can be extracted and used
without the user having to change the name of the extracted
folder.

Chapter 1:
mod folder name MUST be info.json name + _ + info.json version

Chapter 2:
correct place_result note
note: __modname__ references do NOT include _version!
whitespace in code
correct note about starting game (data.lua not requiring prototypes)

Chapter 3:
correct name note, it should be the same but does not HAVE to
more important is result
correct note about stating game

Chapter 4:
correct note: "so it's time to tell the game what files it has to load. "
car:
uses animation instead of pictures
has effectivity in main scope replaces acceleration_per_energy
braking_power added
collision_mask = {} needed instead of removing collision_box

Chapter 5:
add "explosives" to prereqs and correct note about prereqs

Chapter 6:
remove -- in item-description (or the entire line)
correct "The locale.cfg file should be saved" should->must
extend with "I suggest copying an existing one and just deleting the contents so you have the proper encoding"
correct "Notice how bomber has no description, because it is commented out in the local.cfg file. (The bomber isn't really stealthy anyway ) "
this is not a true 'comment' (since we're not typing in lua here) and is instead simply changing the name Factorio looks for, if someone added a '--bomber', this _could_ overwrite their description! If you don't want a description, remove the line instead of 'commenting it out'.

Chapter 7:
update code

[JJosh]

I see what was meant now, and I appreciate the update. Thank you.

May someone help me?
I followed the current tutorial, this was done through copy/pasting and TextWrangler. However, when I load Factorio (in version 0.11.15 since 0.10 is broken for macs) it says:

First the tutorial isn't quite updated to 11 yet (mainly the car prototype used by the bomber has changed), look a couple posts up and you'll see a zip of the partial update (graphics haven't been redone yet). Second, what you posted would indicate an issue with Factorio itself not, exactly, the mod. So the log should be posted in the Bug Reports section with the relevant info (it could be related to the mod if 11.15 works without it so feel free to upload your version with the post).

[wahming]

I've got a mostly-working bomber (it flies, at least) by wholesale lifting of the actual car prototype code. But I'm having a weird problem where it occasionally goes entirely invisible while moving around. Can anybody please advise?

Oh, I'm attaching the modified bomber pic. Maybe it can save you some effort when updating your guide

Edit: Is there anything like an API for the code? Or do we need to dissect the base mod to try and figure out what's available?

Hello Can You Help Me ???
I Creating My 3rd Mod
How so it give me all I need Scripts to create chest's with enlarged number of slots

[Carrum]

Hi! I'm still relatively new to the game and was curious to how the modding scene is. After a lot of wiki and forum reading, I found your tutorial. Kicking and screaming didn't seem to get things working at all, and then I found your partial update.

Here's a partial update

Which was great because it got me a step in the right direction! However, there were still a bunch of errors showing up D:

I've been wrestling these lua errors for about an hour now, slowly editing the control.lua each time.
Eventually I managed to get the mod working, it flies and it bombs appropriately. (really wouldn't mind extending this )
Anyways this is what my resulting control.lua file looks like now, for anyone interested:

Code: Select all

require "util"
require "defines"

-- The code for FreeER's Step By Step Guide to Modding Factorio
-- (Created for Factorio 0.3.x Updated to 0.11.x) AKA Bomber Mod
function init() -- ran when the mod is first loaded
  global.bomber = 0 -- time placeholder
  global.version = "0.1.2"
end

game.on_init(init)
game.on_load(function() if not global.bomber then init() end end)

game.on_event(defines.events.on_tick, function(event) -- ran ~60 times per second
  -- if there are players in the game
  if #game.players > 0 then
    -- then loop through all of them and...
    for _, player in ipairs(game.players) do
      -- if this player has a character (as opposed to being in a sandbox game)
      -- and that character is in a vehicle and that vehicle is our bomber
      -- and that bomber has at least 1 bomb item in it's inventory
      -- and it's been more than 180 ticks (3 seconds) since the last bombing
      if player.character and player.character.vehicle
      and player.character.vehicle.name == "bomber"
      and player.character.vehicle.get_inventory(2).get_item_count("bomb") >= 1
      and event.tick-global.bomber >= 180 then -- delay of 3 seconds per drop
        local bomber = player.character.vehicle -- reference to bomber
        local bombArea = game.surfaces["nauvis"].find_entities{ -- area to 'bomb'
          { -- rectangular area to search by specifying bottomleft and topright xy
            bomber.position.x-5,
            bomber.position.y-5
          },
          {
            bomber.position.x+5,
            bomber.position.y+5
          }
        }
        
        local drop = false -- boolean determining whether we should 'drop' a bomb
        local enemyCount = 0 -- number of biters in bombArea
        
        for index, enemy in pairs(bombArea) do -- loop over entities in bombArea
          if enemy.force.name == 'enemy' then -- if it actually is an enemy
            if enemy.type == 'spawner' then -- count spawners as a priority
              drop = true
              break; -- stop looping now that we know we will drop a bomb
            elseif enemy.type == 'unit' or enemy.type == 'turret' then
              enemyCount = enemyCount + 1 -- count units and worms as 1 'enemy'
              if enemyCount > 5 then -- if five or more will be killed then drop
                drop = true
                break; -- stop looping
              end
            end
          end
        end
        
        if drop then -- if we decided to drop a bomb
          global.bomber = event.tick -- store the time we dropped a bomb
          for index, entity in pairs(bombArea) do
            if entity.force.name == 'enemy' then
              if entity.health then -- if it has health
                entity.die() -- make it die
              else -- no health, so no die method to call
                entity.destroy() -- use destroy
              end
            end
          end
          -- now remove the 'dropped' bomb from the bomber's inventory
          bomber.get_inventory(2).remove{name="bomb", count=1}
        end
      
      end
    end
  end
end)

Again for those interested, the following changes (mainly) were made:

• Changing all instances of glob to global.
  All game functions had to be changed to include underscores between names. eg. game.oninit was changed to game.on_init
  The game.find_entities function had to be called from game.surfaces instead ("nauvis" seems to be the base surface type, so that the script will search all tiles in the area indiscriminately)
  There doesn't seem to be an equals function for the force table, so I compared the force name to "enemy" instead.

Hey I was trying to make a mod similar to "Too many items mod" for minecraft (Idk if one exists or not but either way this is my first factorio mod I need the practice) and I as wondering why my current code will not work... My overall goal is too make everything cost one stone or make everything cost nothing (if that is possible)... I tried to make a recipe that costs one stone and yields one iron plate however i cannot seem to figure out why it does not work. Factorio Does not give me an error on start but the recipe does not show up anywhere (*Should be in weapons tab I think)


Also can I add a new tab for making cheat items.... Or just make a menu that you can click n something in and receive it???

Code: Select all

data:extend({
 {
    type = "recipe",
    name = "Iron",
    enabled = "true",
    ingredients = 
    {
      {"stone", 1}
    },
    result = "iron-plate"
	subgroup="ammo"
  })
