Hello and good time of day.

How to ensure that (existing, my own) mod work well in multiplayer?
Many scripting, many new entities.

Is there some recomedndations somewhere?

Thanks in advance.

Just a few things:

• Store all of your mutable variables in the "global" table. If you don't know what mutable means - just store all of your variables in the "global" table.
• Only run code in reaction to a event
• Make sure you don't mutate things in the on_load event. If you don't know what that means just avoid the on_load event.

Past that, it should 'just work'.

use game.players[#]. instead of game.player.

game.player also doesn't work in singleplayer... it's only available from the console, nowhere else

you'd be surprised how many mods fail to work because they've used game.player in their scripting.

but don't ever hardcode game.players[1], instead either loop over all players or use the player involved in whatever event that triggered the code
