[1.17] Loop stopping the game

[lGuestll666l]

When im using BlockEvent.EntityPlaceEvent to detect when block is placed

try {

    Thread.sleep(4000);

    event.getWorld().setBlock(event.getPos(), Blocks.AIR.defaultBlockState(), Constants.BlockFlags.BLOCK_UPDATE);

    LightningBolt bolt = new LightningBolt(EntityType.LIGHTNING_BOLT, event.getEntity().level);

    bolt.moveTo(new Vec3(event.getPos().getX(), event.getPos().getY() - 1, event.getPos().getZ()));

    event.getWorld().addFreshEntity(bolt);

    while (true) {

        Thread.sleep(1000);

        String msg = ChatFormatting.RED+"Hello : )";

        event.getEntity().sendMessage(new TextComponent(msg),event.getEntity().getUUID());

    }

} catch (InterruptedException e) { e.printStackTrace(); }

And the leave the world, game just infinity saving world screen.

Someone know how to make loop without infinity loading screen after leaving?

You need to count ticks. The game only runs one thread for the main logic. If you sleep there, you're stopping the whole game.

Also: That is not at all how you ever handle exceptions.

Can you send an example of counting ticks function please?
