Map reset system

[nimble helm]

Hello so I am trying to create a minigame and I want to reset the map after every game automatically I was thinking about using storage to store block locations with IDs and avoid using ray casting, is there actually any way of doing this ?

[rough kettle]

you could store the map somewhere else and use /clone

or as a structure/multiple structures and then use /place

[nimble helm]

What if the map is big ?

[rough kettle]

do it in sections

so ie multiple clone commands

[vale socket]

this really only applies in specific scenarios depending on what the minigame is, but i figure it might be useful

you can set all the air in your map to be void_air, which makes no visible or functional difference, but allows you to tell when a block has been broken (it will make a tile of regular air)

[rough kettle]

That isn’t really helpful here I don’t think

[vale socket]

unless all the blocks are the same and the player cant place blocks, yeah 💀

overall the /clone sila mentioned is prob the most practical and simple solution

[nimble helm]

Yup I got another problem I don't want the players to break map blocks but I want them to break and place the block that they placed/broken

[vale socket]

oh thats doable if they have different blocks than the ones that are already placed

you can put them in adventure mode and give them blocks with “can be placed on” tags, and tools with “can break” tags

if you want them to be able to break the same kind of block as youre using for decoration in the base map

[nimble helm]

Like Shears for wool

[vale socket]

its still theoretically doable but more difficult ofc

[vale socket]

and yeah, thats one example

but you could set any tool to any block

or blocks

[vale socket]

(this would probably be a better job for a plugin)

[nimble helm]

But if the map is big enough (UHC run) and I have multiple worlds, setting it up in sections will take a lot of time

[vale socket]

you can probably do it systematically

it will certainly take time but i think that may be unavoidable

[nimble helm]

(That's why I was trying to use something like storage and get the block locations stored)

[rough kettle]

Using a storage for every single block isn’t a good idea

NBT can get very laggy

[nimble helm]

I mean I can store them in one storage with path IDs and then I can use something like /setblock with macro

[rough kettle]

but every single block?

[vale socket]

that could work, but it could probably be much easier to make some kind of datapack that saves a far corner and the x, y & z length for a cube of area to copy, as well as a destination corner, to systematically/dynamically grab and paste chunks

[rough kettle]

I would do it in rows

[vale socket]

prob easier

but same idea either way

[rough kettle]

so like, all blocks in x=1, then x=2, etc

but yeah depends on the shape of the map too

[nimble helm]

That could cause some lag but still wouldn't it be better than replacing all blocks ?

[vale socket]

honestly i think it would probably be laggier to grab nbt data for every single tile

[rough kettle]

^^^

[vale socket]

what you COULD do is save the tiles players change, but that would require raycasting, which you wanted to avoid

[nimble helm]

Hmm so clone it is

[rough kettle]

there’s 90K blocks per chunk if you include -64 to 319

[vale socket]

you could also use a library such as retina to make raycasting a lot easier, but its up to you and what you find easiest in the end

[nimble helm]

I'll go with clone command

[rough kettle]

but there’s also stuff like tnt explosions, jumping on crops, etc which wouldn’t be captured by the raycast

[vale socket]

yeah, depending on the minigame, for sure

raycasting can be fickle 😔

fair warning, /clone en masse may also be laggy, but i think its a lesser evil in this case

[nimble helm]

Or I could add a cooldown system to make it slower ?

[rough kettle]

basically noting is as laggy as NBT operations AND macros

[vale socket]

yeahhh

lol

[nimble helm]

I replied to the wrong message

[vale socket]

except like, summoning structure locating maps

[rough kettle]

you could do one /clone per tick. That way it’s not rspecially laggy but it will take like a couple of seconds to clone the entire map

[vale socket]

yeah

only other issue is loading things in

if players could be not loading the map and its copy in, youd have to use forceload commands

ofc thatd be an issue with the nbt too

[nimble helm]

Structures could be better ? since I don't have to create an extra copy ?

[vale socket]

tbh with you i hardly know the drawbacks and such of structures because i havent touched worldgen much yet

[nimble helm]

Me too

[vale socket]

ig id wait for sila or someone else to answer that

[rough kettle]

structures should be just as easy tbh

more difficult to make changes to such as if you want to add chests or stuff to it, since you’d have to save the structures again each time

but a bonus is that you won’t have to forceload the copy of the map

[nimble helm]

Hmm it's for my minigame server and that wouldn't take a lot of time so it's fine
