Hi,

I did a very quick Google and found that mods don't have access to networking (I'm looking for a simple HTTP(s) client) - is this true ? If so, is this something that will be considered in the future ?

Thanks !

Some reasons this will never happen:

• Allows for data exfiltration from the game sandbox by smuggling it in the request body
• Multiple clients making HTTP requests (in multiplayer) could get different responses from the server, causing desyncs
• Latency of waiting for a response would make for an awful user experience

The best you can do is write_file to the script-output/ folder. On multiplayer servers you can use the RCON interface to run console commands, including LUA scripts. There is also send_udp / recv_udp which requires the data to be replicated to all multiplayer users.

Good Luck!

Sorry, but you answer seems to focus a lot on multiplayer - my focus is way more on single player. The idea is that you have 2 or more players and using this mod, you can share resources between players. Players will need to load said resources into a train and send it to a station. The train (including resources) will then "disappear" from the player's map and spawn on the target players map, where it will go towards a station, rinse repeat.

The network parts will be the exchange of resources, so no real player XP impact that I can see?

Does the mod code not run in it's own thread ?

Thanks !

Singleplayer and multiplayer follow the exact same game logic - the player’s character controller is just “local”.

You may find Subspace Storage and Clusterio interesting.

Oh I see - thanks !

I see we have (as you mentioned) send_udp,recv_udp - even thou this seems to only be "bound" to localhost I can still use this - TO THE LAB !
