From what I findo out, some say that it should be used in the <profile>.json file

under "minecraftArguments": " " like:

"minecraftArguments": " --modListFile file1.json "

it must have a filePath assigned like --modListFile ModList1.json and such file under ".\.minecraft\ModList1.json"

and it must contain:

{
  "repositoryRoot": "/home/squiddev/mods",
  "modRef": ["computercraft.jar", "cctweaks.jar"]
}

but the information source was not 100% sure of that.

Can anyone help me on that?

Bump, is this forum dead?

The root object of the list file can contain three properties:

• repositoryRoot

  (string) - The root directory. All mod paths are relative to this.
  

• modRef

  (array of strings) - An array of mod references to load.
  

• parentList

  (optional string) - The path of the parent list, if any. If specified, FML will load this list as well as the current one. This can be chained (e.g. list A inherits from list B, which inherits from list C), but not looped (e.g. list A inherits from list B, which inherits from list A).
  

 

Each mod reference is a string in the following format:

"<group>:<name>:<version>[:<classifier>]"

 

The path of the mod JAR is built from these components in the following format: <repositoryRoot>/<group>/<name>/<version>/<name>-<version>[-<classifier>].jar

 

The square brackets denote an optional part; if no

classifier

is specified, it won't be used in the path.

 

Any period (

.

) in the

group

will be replaced with a directory separator.

can you please give me an exemple of a modlist file?

{
"repositoryRoot": "jsonmods",
"modRef": [
	"dan200:ComputerCraft:1.78",
	"org.squiddev:CCTweaks:1.8.9-0.3.2"
]
}

 

This will load two mods: <gameDir>/jsonmods/dan200/ComputerCraft/1.78/ComputerCraft-1.78.jar and <gameDir>/jsonmods/org/squiddev/CCTweaks/1.8.9-0.3.2/CCTweaks-1.8.9-0.3.2.jar (where <gameDir> is the game directory specified in the client's launcher profile or the server's directory).

wow, so i need to make a folder tree for each mod i'm using?

Isn't there an easier way to make mod profiles? (with stock launcher)

You can use the

--mods

command line argument (a comma-separated list of mod files) or just create a separate game directory for each profile.

 

I think the mod list file was mainly intended for modpack launchers (e.g. ATLauncher) to store their mods in a central location shared between all instances/profiles and still only load the mods for the launched pack.

about this "--mods" arg how do use it?

'cuz i tried using the game folder and it still loaded all the mods in the main game folder.

Yes I did that, it loads mods from all folders.

about this "--mods" arg how do use it?

 

Like I said, it's a comma-separated list of mod files to load. There's not much more to it than that.

like "--mods mod1.jar, mod2.jar, mod3.jar," ?

like "--mods mod1.jar, mod2.jar, mod3.jar," ?

 

--mods "modsDir1/mod1.jar,modsDir1/mod2.jar,modsDir2/mod3.jar"

that will be way easier, thankyou very much. Have a nice easter.

btw. i put that here right?

 

"minecraftArguments": "--username ${auth_player_name} --version ${version_name} --gameDir ${game_directory} --assetsDir ${assets_root} --assetIndex ${assets_index_name} --uuid ${auth_uuid} --accessToken ${auth_access_token} --userProperties ${user_properties} --userType ${user_type} --tweakClass net.minecraftforge.fml.common.launcher.FMLTweaker --mods "modsDir1/mod1.jar,modsDir1/mod2.jar,modsDir2/mod3.jar""

Assuming that's in a JSON file, you need to escape the quotation marks for the

--mods

argument by placing a backslash in front of them:

 

"minecraftArguments": "--username ${auth_player_name} --version ${version_name} --gameDir ${game_directory} --assetsDir ${assets_root} --assetIndex ${assets_index_name} --uuid ${auth_uuid} --accessToken ${auth_access_token} --userProperties ${user_properties} --userType ${user_type} --tweakClass net.minecraftforge.fml.common.launcher.FMLTweaker --mods \"modsDir1/mod1.jar,modsDir1/mod2.jar,modsDir2/mod3.jar\""

 

Does the Mojang launcher actually support passing arguments to Minecraft like this?

yeah thats the profile.json inside the versions folder.

like, "forge version.json"
