COOP and MODs

[M.I.K.E.]

Can i still play coop if we install mods?

Yes. Just make sure, that all players have the same version of the same content mod. Some gameplay mod (like altering length of day or cheat mods) might still work for the host, even when the other players doesn't have it and purely visual changes definitely work without the others needing it as well.

Thanks for you answer :)

There may be some lag issues if you have a lot of them but shouldn't have any serious troubles :)

Desync is the bane of coop games, and it happens when the game detects that one player's world is different from another player's. If someone adds a random element in their mod, for instance, and that can cause differences, then that mod may cause a desync.

Most mod makers know this, and either make the randomness not truly random (True randomness is complicated to do on a pc anyway) or don't include actually random elements.

This is why both must have the same mods - to avoid world differences. For instance, the appearance of an item isn't communicated, only the ID number. If the item looks different on one PC to another, that doesn't really matter, so for this purpose, purely graphical mods are irrelevant. But if you try to pick up an item that one game thinks doesn't exist, or tries to hit a slime with a weapon that the other game thinks is an edible fruit, that causes problems.

If you start getting a lot of desync errors - they are sometimes caused by particular sequences of network packet loss as well, so A desync isn't problematic, but if you get them consistently or frequently - depending on net code - then one of your installed mods may be poorly implemented for coop play.

This is true of all coop games, although if the game has mod support - SDV doesn't - then it may enforce identical mod lists.
