Really weird multiplayer bug?

[code99]

Hi,

Long story short, me and my friend want to play in multiplayer.

We join the came, no problems but once in game my friend cannot interact with anything. He can do right click actions like cutting trees, mining but he cant open entities with left click! However, it all works in single player, when he starts a game in single player, he can play normally. It only happens in multiplayer.

Meanwhile everything works for me. I can play normally in mp.

We have the same version of the game and the same mods (we do use a lot of mods).

Ideas?

Could it be that you're on different forces / teams?
This can happen if you changed the force you are on from the default "player" force with mods or console commands.

Does he get an error message (Can't open enemy structures) when trying to open an entity?

[code99]

Thats not it.

He couldnt open anything, not even his stuff.

I instead could, he placed a chest and a furnace and I could open those and work with them, he couldnt.

Does it work without mods?

Sounds like his controls are messed up. Has he checked the controls section to make sure nothing is out of place?

[code99]

But it works in single player ... controls change from sp to mp?!

Does it work without mods?

We will try and see.

Altho i dont think thats it either ... in single player with the same mods enabled he can play normally without a problem. Its only in mp that the problems start happening ... but we will try vanilla and see whats what.

A mod could hardcode things like game.get_player(1) to get at a player object, so it would work fine in singleplayer but not when there are multiple players. Though I don't know how a mod could disallow opening entity GUIs.

We tried vanilla ... he cant open anything while I can so its not mod related.

No more ideas?

No more ideas?

I assume you were the host for now. Does it work if he hosts the game (on a new map)?
Also, what version are you playing on?

[code99]

Doesnt matter now.

We fixed it. I told him to delete everything related to Factorio, restart pc, install factorio again etc.

Now it works. Ultimately not sure what was the problem exactly but at least it works now.
