Can you use player.location as a coordinate?

[swift yacht]

yes

[vapid ore]

you can, but for this case it would be better to just use StructureManager

[wheat thunder]

I wanted to copy an area before it was deleted and then replace it

[vapid ore]

world.structureManager.place("structureId", world.getDimension("overworld"), player.location)

[wheat thunder]

But I don't know how to use structureManager... I looked in the documentation, but I didn't understand

[swift yacht]

player.dimension

[vapid ore]

yeah, that's better, slipped my mind

[wheat thunder]

Is there a way to copy an area using this?

[vapid ore]

createFromWorld is how you'd save a structure

[wheat thunder]

For example
world.structureManager.save()

[wheat thunder]

Could you give me an example of how to copy an area/radius?

[vapid ore]

const newStructure = world.structureManager.createFromWorld("newStructure", player.dimension, {x: 0, y: 0, z: 0}, {x: 32, y: 32, z: 32});

world.structureManager.place(newStructure, player.dimension, player.location)

that would save an area from 0 0 0 to 32 32 32 and then place it again at the player's location

[swift yacht]

where are you using it for exactly? before tnt explode or something?

[wheat thunder]

Yea

[vapid ore]

so you want to save the area before tnt explodes and then place it back later to regenerate the area?

[wheat thunder]

Yeeees

[vapid ore]

this might not be the best solution for that

it would have issues if multiple tnts go off in that area

[swift yacht]

yeah this will cause lags

[vapid ore]

lag isn;t the problem

it wouldn't be that bad for performance

[wheat thunder]

It's not a problem, because I did something to hide this lag

[wheat thunder]

How could I do this in an easier way?

[swift yacht]

it will load the same structure for the other place

[wheat thunder]

I would do everything by several commands in one function 😔

[vapid ore]

are you using stable APIs or beta APIs?

[wheat thunder]

Load the structure in the same place

[wheat thunder]

Yea

[vapid ore]

which one

[wheat thunder]

I'll summarize... Where the player destroys the structure, a mob is spawned that takes the player's name

This mob will save the structure around it and after a while, rebuild

[vapid ore]

are you using 1.11.0 or 1.12.0-beta

[wheat thunder]

1.12.0-beta

[swift yacht]

i think iterate each block that is affected inside ExplosionBeforeEvent, with
getImpactedBlocks()

[wheat thunder]

Blocks do not explode

[swift yacht]

oh

[wheat thunder]

A structure is placed in player location

And when the structure disappears, the area it destroyed must return to the way it was before

[vapid ore]

so the blocks don't explode, you're just making a fake explosion in its place?

[wheat thunder]

I'll show you, just a minute

[swift yacht]

oh so you want to spawn a structure without losing the previous environment? then retrive back the environment right after the player breaks a block

or im getting it wrong

[wheat thunder]

@swift yacht @vapid ore

[vapid ore]

oh it's not an explosion at all

[wheat thunder]

This structure will break surrounding blocks within a 28 block radius

I want to save the area, so when this structure disappears, it goes back to how it was before

[wheat thunder]

This structure weighs 42kb

[swift yacht]

skill activate -> save structure for whatever the size of that is, offset it rightly -> wait for structure despawn/remove -> reload the original environment

basically thats it, just experiment the offsets on structureManager.createFromWorld()

[wheat thunder]

Yea

It seems difficult, but it's not

Could you explain to me how structureManager works?

So I could try to do it, I guess

[vapid ore]

const { x, y, z } = player.location;
// get the minimum and maximum coordinates of the affected area
const areaMin = { x: x - 28, y: y - 28, z: z - 28 };
const areaMax = { x: x + 28, y: y + 28, z: z + 28 };
// create a backup of the affected area
const areaBackup = world.structureManager.createFromWorld(`areaBackup:${player.name}`, player.dimension, areaMin, areaMax, { includeEntities: false });

system.runTimeout(() => {
  // place the backup back into the world to restore the area
  world.structureManager.place(areaBackup, player.dimension, areaMin);
  // delete the structure so it's no longer taking up space in the world
  world.structureManager.delete(areaBackup);
}, 60);

something like that should work

[wheat thunder]

WOOOOOW

[vapid ore]

this creates a backup and then places it back into the world after 3 seconds

[wheat thunder]

Bro, I don't even know how to thank you for this

[vapid ore]

details on the structureManager can be found here
https://jaylydev.github.io/scriptapi-docs/1.21.0/classes/_minecraft_server_1_11_0.StructureManager.html

[wheat thunder]

Very thanks

[swift yacht]

you'll have problems if both players execute the skill at the same location consecutively

[vapid ore]

yeah, you'll need to handle that situation since I didn't write anything for that

[wheat thunder]

I already solved this

The entity that is in the middle of the structure creates an area property... It is only possible to create another structure outside this area
