in survival with op

[ilobilo]

is there any way to use this mod in survival mode with cheats enabled?

There isn't currently a way to do this. The main issue is that (server-side) commands are limited in characters, so automatically calling a command like /item replace entity @s inventory.<slot> with <item> would be restricted to very simple items. In theory it could automatically call /gamemode creative, then send the item set packet, then /gamemode survival, but that isn't ideal.

While anything that modifies your inventory doesn't work, the mod currently already supports the client chest, which would allow you to transfer items from a survival server (no op required), but not to a survival server. I believe you can also edit items within the client chest, but I haven't tried it. In theory it should work though. Obviously that isn't really what your looking for.

In theory nbt can be "built" by running successive /data modify|merge commands on nbt storage. However it would probably be very slow. It would also require a container or entity as an intermediary to transfer the item from nbt storage back into your inventory. Basically this would be automated:

1. /data modify storage nbteditor:username_rand item set from entity @s Inventory[{Slot:<slot>}]
2. Repeatedly, keeping chars under limit: /data modify storage nbteditor:username_rand <changes in nbt here>
3. /data remove storage nbteditor:username_rand item.Slot
4. /summon pig ~ ~ ~ {"nbteditor:username_rand":1b}
5. /item replace @e[type=pig,nbt={"nbteditor:username_rand":1b},sort=nearest,limit=1] armor.head with stone
6. /data modify entity @e[type=pig,nbt={"nbteditor:username_rand":1b},sort=nearest,limit=1] Inventory[0] merge from storage nbteditor:username_rand item
7. /data remove storage nbteditor:username_rand item
8. /item replace entity @s inventory.<slot> from entity @e[type=pig,nbt={"nbteditor:username_rand":1b},sort=nearest,limit=1] armor.head
9. /kill @e[type=pig,nbt={"nbteditor:username_rand":1b},sort=nearest,limit=1]

This also doesn't work if the entire path and value of a single tag is longer than the limit (mainly a problem in long strings).

Is there a particular technique mentioned above that you want me to try implementing?

I found another nbt editor plugin: https://github.com/qyl27/NBTEdit, it's not as easy to use but it just needs op and can edit items in survival mode. I don't know much of java and can't find how they do it but i think it could be useful to you.

It looks like that mod is both client-side and server-side, so it only works on modded servers that include that mod (or singleplayer). Mods that are on both the client and server are much more powerful, as they can have things like a custom survival mode item editing packet. Generally I would like to keep this mod fully client-side, as it gives more flexibility to where it can be used; it works in vanilla servers, and even forge servers that don't require client side mods.

I have been considering making this mod server-side optionally, meaning that all of the current features still work, but special features like survival-mode editing, entity editing, etc. would be added. I'll look into the concept some more, but I can't guarantee it will come out soon; I don't have much experience with client-server communication in mods.

That would be great, thanks!

I've now added this in v2.0.0!
