Accessing other players' inventories

by zeuner » Post

I noticed that when using the list[] element in a formspec, it will show lists from the current player's inventory, or detached inventories, but I don't seem to able to show another player's inventory using the player:<playername> syntax. It just doesn't show up, but there is also no error message.

Is this behaviour documented somewhere? I suppose that the player:<playername> will work under certain circumstances since it wouldn't be mentioned in doc/lua_api.txt. I would like to implement some UI-based interactions involving different players' inventories, so I need to better understand what is possible.

I had this error when trying to do this a bit ago.

It doesn't show up because the player is only sent their inventory, so it doesn't know what to show.

The only option would be to make some implementation, such as a grid of images and simply display that, or to clone the player inventory into a detached inventory. You could possibly even use detached inventory callbacks and global step (or 5.0-dev) to try keep the 2 synced.

Thanks for the information. It seems as if detached inventories will work for me.

Still, the described behaviour seems to be undocumented, which makes the platform harder to understand for new modders. Therefore, I would suggest to make it more clear: https://github.com/minetest/minetest/pull/7720
