1.20.2 [SOLVED] Need help with generating structures.

[Sam__Wilde]

Hello, I want to create an item that when used, generates a structure. (structure don't generates naturally in world)

Now I am having trouble generating a structure (jigsaw).
The code below works, BUT the structure does not appear in the world until I re-enter it. This is a significant flaw that I would like to get rid of.

My current code:

public class MineshaftSpawnerItem extends Item {

    public MineshaftSpawnerItem(Properties pProperties) {
        super(pProperties);
    }

    @Override
    public @NotNull InteractionResult useOn(UseOnContext pContext) {
        Level pLevel = pContext.getLevel();
        Player pPlayer = pContext.getPlayer();
        BlockPos pBlockPos = pContext.getClickedPos();
        ItemStack item = pContext.getItemInHand();
        if (!pLevel.isClientSide()) {
            assert pPlayer != null;
            item.setCount(0);
            String command = MessageFormat.format("place structure weirdoitems:mineshaft {0} {1} {2}",
                    pBlockPos.getX(),
                    pBlockPos.getY(),
                    pBlockPos.getZ());
            System.out.println(command);

            try {
                Objects.requireNonNull(pLevel.getServer()).getCommands().getDispatcher().execute(command, pLevel.getServer().createCommandSourceStack());
            } catch (CommandSyntaxException e) {
                throw new RuntimeException(e);
            }

        }
        return InteractionResult.PASS;
    }
}

I know about the PlaceCommand.placeStructure() method, but I can't figure out how to use it, and I can't find any documentation or examples of how to use it on the internet.

 

Edit:

I searched and tried normal options to solve this problem for a very long time, but nothing. I ended up doing it like this. And it works (in my case).

@Override
    public @NotNull InteractionResult useOn(UseOnContext pContext) {
        Level pLevel = pContext.getLevel();
        BlockPos pBlockPos = pContext.getClickedPos();
        ItemStack item = pContext.getItemInHand();
        if (!pLevel.isClientSide()) {
            item.setCount(0);
            JigsawBlockEntity jigsawBlockEntity = new JigsawBlockEntity(pBlockPos, Blocks.JIGSAW.defaultBlockState());
            jigsawBlockEntity.setPool(Pools.createKey("weirdoitems:mineshaft/tunnels"));
            jigsawBlockEntity.setName(new ResourceLocation("weirdoitems:tunnel"));
            jigsawBlockEntity.setTarget(new ResourceLocation("weirdoitems:tunnel"));
            jigsawBlockEntity.setFinalState("minecraft:oak_planks");
            jigsawBlockEntity.generate((ServerLevel) pLevel, 7, false);
        }
        return InteractionResult.CONSUME;
    }

make your item spawns the minecrafts extructure block at the desire position 
gets the block entity from that block and use the block entity to load and spawns the extructure
