layer by layer

[skanto123]

on place of stone:
if name of player's held item is "&ctest":
set blocks within chunk at event-block where [block input is not bedrock] to air

how do i make it do it a layer by layer so from 255 then 254 then 253 all the way to bedrock

 

[Donut]

set {_layer} to 255.5
loop 255 times:
    set blocks within chunk at event-block where [block input is not bedrock] where [y-coord of block input is {_layer}] to air
    remove 1 from {_layer}
    wait 1 tick

the layer starts at 255.5 because the y-coord of a block is always something.5

doing it one time is fine but 255 times? I'm more than sure this will lag your server.

na i tested it

it might be normal for a player within a local server (no latency), but what about a server with i.e: 50 players? 50 of which let's say 13 execute this effect, don't you think it will lag if 13 personsa re doing it within the same amount of time?.

no i dont think itll lag because its only setting 1 layer of blocks to air at one time which isnt alot. idk if you saw in the other thread where he wanted the whole chunk set at once and it still didnt lag much

I saw it however, it's the same case, it will have a different impact with many players executing it. Your code has to go through all the blocks in the chunk, check if they aren't air nor bedrock, and then set these blocks to air, the calculation itself could be expensive at some point.

So, if the OP wants this, you may make sure there is a delay or that it isn't executed regularity or your server will lag a lot otherwise.

I tested it and when I make it to set the whole chunk to air it creates less lag that a layer at a time

That's because the code donut gave you loops every single block in the chunk 255 times each. It will still set the same number of blocks but it will loop a lot more.
Instead you want to do something like

set {_layer} to 255.5
loop 255 times:
    set layer {_layer} of chunk at event-block
    remove 1 from {_layer}
    wait 1 tick
