i mean i try this code

[solemn lark]

    @EventHandler
    public void loadChunk(ChunkLoadEvent e) {
        ChunkSnapshot chunk = e.getChunk().getChunkSnapshot();
        System.out.println("test1");
        World world = e.getChunk().getWorld();
        for (int x = 0; x <= 15; x++) {
            for (int z = 0; z <= 15; z++) {
                for (int y = chunk.getHighestBlockYAt(x,z); y > world.getMinHeight(); y--) {
                    System.out.println("test2");
                    Block block = e.getChunk().getBlock(x,y,z);
                    if (block.getType() == Material.WHEAT) {
                        block.setType(Material.DIAMOND_BLOCK);
                        System.out.println("test3");
                    }
                }
            }
        }
    }```

i rejoin server isnt working but

if i wait 10 sec and join server

working

so for the unload chunks i need wait some time

[mental anchor]

if the chunk is loaded that code never runs

[solemn lark]

why ?

wdym for chunk is loaded

[mental anchor]

if you log out and back in the chunk doesn;t unload

[solemn lark]

so i need method for unload chunk ?

[mental anchor]

your original request was to grow wheat for the time the chunk was unloaded.

[solemn lark]

example
if player left chunk unload chunk

[mental anchor]

you are not actually growing wheat

[solemn lark]

ah actually i will do

check chunk time with pdc and unix time

[mental anchor]

then this replacing it with a diamond block is pointless

[solemn lark]

and add ifs system.time > time + 1000000 after on load chunk set crops

[mental anchor]

if the chunk is loaded it will grow naturally

[solemn lark]

for the test

[mental anchor]

this is not a good test

[solemn lark]

let give me a time for do my code

then please close my mistakes

[mental anchor]

you need to grow the wheat not replace it with a diamond block.

this code will work then

[solemn lark]

i have custom crops system

i don't use all wheat stages

so i need check some crop stages

i will show u 1m

[mental anchor]

I don;t need to see

you need a method that grows wheat

you then call that method with the length of time that has passed

[solemn lark]

i will do

let give me a time
