Weird block glitch on interact

I get a weird block glitch when i interact with some blocks on an island i created with this code

Code:

public function generateChunk(int $chunkX, int $chunkZ) {
        $chunk = $this->level->getChunk($chunkX, $chunkZ);
        $chunk->setGenerated();
        if ($chunkX % 20 == 0 && $chunkZ % 20 == 0) {
                //set block on chunk
                }
            Tree::growTree($this->level, $chunkX * 16 + 3, 6, $chunkZ * 16 + 4, $this->random, 0);
            $chunk->setX($chunkX);
            $chunk->setZ($chunkZ);
            $this->level->setChunk($chunkX, $chunkZ, $chunk);
        }
    }

You can see this gif of what happens ->

Spawn protection = -1
Even with no editing on playerinteractevent
Does anyone know why this is happening or how to fix?

 

Does this still happen after relog/are the blocks really gone even afer relog?

 

no, the blocks are back after relog but why does this happen?

 

This is really weird, do you have any plugins interfering with PlayerInteractEvent or PlayerActionPacket?

 

@Muqsit No, i only have devtools and the plugin i am working on, no event listener yet. This only happens when i generate the island and teleport to it in the same session after loading the level, not after relogging. Also i generate the island at level's spawn and spawn protection is -1, if that has anything to do with it.

 

then this suggests a client issue. try teleporting the client out of reach and then in reach again after generating

 

what do you mean by out of reach?

 

no wait i get the same glitch after respawn only the blocks appear back, you can still interact and the blocks disappear

 

this is really weird, how are you generating exactly and when are you putting the player on top of the island?

 

When the player does /is go they go on top of the island, i am modifying this plugin, it happens in this plugin too, here's the generation -> https://github.com/TheFixerDevelopment/SkyblockPE/tree/Pocketmine-ONLY/src/SkyBlock/generator

 

@robske_110 (Tim) did you check?

 

I did, but I’m pretty clueless. dktapps said there might be a race between chunk sending and generation, but i don‘t understand why and what the result would be.

 

Call $chunk->setPopulated() after $chunk->setGenerated()

 

still happening, i did this -->

Code:

$chunk = $this->level->getChunk($chunkX, $chunkZ);
$chunk->setGenerated();
$chunk->setPopulated();

 

so is their a fix? @robske_110 (Tim)

 

Did you try calling setPopulated() after you've actually populated the chunk, not before?

 

Yes at the end of generateChunk()
