[1.12.2] World.setBlockToAir doesn't work

[ReshiramRocks12]

Hi. I'm having a little trouble with the setBlockToAir method in the World class. I am trying to set a TNT block to air but it doesn't remove it properly and if I walk into the position where the block existed, it glitches my player. It doesn't output any errors in console and it says that the block has been removed whenever I print out the block at that location though it reappears whenever I relog. How can I fix this?

You are likely removing the block on the client. It must be done on the server.

How do I remove the block server side?

I'm removing the block in a Living Update Subscribe Event and getting the world instance using event.getEntityLiving().getEntityWorld();

The event is firing on client side but I am unsure how to make the event fire on server side. How could I do this? Thank you for your help so far

I am using a singleplayer world as my testing world. Do I need to have an actual multiplayer server to make it work?

This is my code.

 

@EventBusSubscriber
public class TNTDefusalHandler
{
	@SubscribeEvent
	public static void onLivingUpdate(LivingUpdateEvent event)
	{
		Entity entity = event.getEntityLiving();
		World world = event.getEntityLiving().getEntityWorld();
		BlockPos pos = new BlockPos(entity.getPosition().getX(), entity.getPosition().getY() - 1, entity.getPosition().getZ());
							
		if (world.getBlockState(pos).getBlock() == Blocks.TNT)
		{
			world.setBlockToAir(pos);
		}
	}
}

I fixed the problem by moving the code into a PlayerTickEvent. Thank you for your help.

Wut?

 

There is nothing wrong with your current event subscriber except that it also triggers on the client. Add a simple if check to fix the problem.
