The fxmanifest and rdr3_warning

The fxmanifest and rdr3_warning

A RedM resource declares game 'rdr3' and carries the rdr3_warning line word for word, or it does not start. A minimal manifest you can copy.

Per ora questa documentazione è in inglese.

Last updated

Every resource has an fxmanifest.lua in its root folder. On RedM it is the same file as on FiveM with two differences: the game line says rdr3, and there is one extra line, rdr3_warning, that has to be there exactly as written.

A minimal RedM manifest

fxmanifest.lua
fx_version 'cerulean'
game 'rdr3'
rdr3_warning 'I acknowledge that this is a prerelease build of RedM, and I am aware my resources *will* become incompatible once RedM ships.'

lua54 'yes'

client_script 'client.lua'
server_script 'server.lua'

Next to it, a client.lua and a server.lua, then ensure your_resource in server.cfg. That is a working resource.

Line by line:

Line What it does on RedM
fx_version 'cerulean' RedM needs adamant, bodacious or cerulean. The old __resource.lua style manifest does not work here.
game 'rdr3' Says the resource runs on RDR2. common means “any game, Cfx.re APIs only”.
rdr3_warning '...' Required whenever rdr3 is one of the games. See below.
lua54 'yes' Lua 5.4, the same as on FiveM.

The rdr3_warning line

This is the exact text, the same one the stock Cfx.re resources carry (it is copied from mapmanager’s manifest in citizenfx/cfx-server-data):

Text
I acknowledge that this is a prerelease build of RedM, and I am aware my resources *will* become incompatible once RedM ships.

It is an acknowledgement, not a comment. If the line is missing, or the text differs by a single character, the server refuses to start the resource. The usual ways to break it:

  • retyping it instead of pasting it, and losing the * around will;
  • an editor turning the straight quote in I acknowledge into a curly one;
  • wrapping it onto two lines.

Tip

The fxmanifest Generator opens on game 'rdr3' with this line already filled in, and the RedM Files page checks a manifest you drop on it for both lines.

Running on both games

A resource that has no game specific code (a chat command, a database helper, an NUI page that does not call natives) can run on both:

fxmanifest.lua
fx_version 'cerulean'
games { 'gta5', 'rdr3' }
rdr3_warning 'I acknowledge that this is a prerelease build of RedM, and I am aware my resources *will* become incompatible once RedM ships.'

The warning line is still required, because the resource does start on rdr3. A resource with only game 'gta5' does not start on a RedM server at all.

Everything else is the same

fx_version, lua54, shared_script, files, ui_page, dependency, data_file and this_is_a_map mean what they mean on FiveM. The FiveM guide to your first resource covers them.

What a data_file line or a stream/ folder can replace is a different list, because the files are RDR2’s. The Resource Conflict Checker tells you when two of your resources stream the same RDR2 file.
