[1.8]Changing Block State on Server Tick Event

[BR3TON]

Hi,

 

I am calling my change block state method from server tick event grabbing the world from the dimension ID but the blocks don't change in the world.

 

	@EventHandler
@SubscribeEvent
public void serverTickEvent(TickEvent.ServerTickEvent e) {

	World world = DimensionManager.getWorld(0);

	//worldTicks = world.getTotalWorldTime();

		for (int i = 0; i < world.playerEntities.size(); i++) {
			EntityPlayer player = (EntityPlayer) world.playerEntities
					.get(i);

			int randX = world.rand.nextInt(16);
			int randZ = world.rand.nextInt(16);

			int playerPosX = MathHelper.floor_double(player.posX);
			int playerPosZ = MathHelper.floor_double(player.posY);

			int randY = getTopBlock(world, randX + playerPosX,
					randZ + playerPosZ);
			byte effectRange = 7;

			for (int zOffset = -effectRange; zOffset <= effectRange; zOffset++) {
				BlockPos blk = new BlockPos(randX + playerPosX, randY, randZ + playerPosZ);
				IBlockState block = world.getBlockState(blk);

				//
				setBlockState(Blocks.dirt, new BlockPos(blk.getX(), blk.getY(), blk.getZ()), world);


				// if its grass
				/*if (block == Blocks.grass || block == Blocks.mycelium) {

					setBlockState(Blocks.dirt, new BlockPos(blk.getX(), blk.getY(), blk.getZ()), world);
				} else {
					System.out.println("No Grass");
				}*/
			}
		}
	}
//}

private void setBlockState(Block block, BlockPos pos, World world) {
	if (!world.isRemote) {
		IBlockState state0 = block.getDefaultState();
		world.setBlockState(pos, state0);
		System.out.println("Block changed");

	} else {
		System.out.println("Block not changed");
	}
}

 

The console spams out Block changed so the code is being ran but I see no visual change in the world.

The change is not being sent to the client.

 

Change your setBlockState method from

world.setBlockState(pos, state0);

to

world.setBlockState(pos, state0, 2);

where the 2 is a flag that sends the updated state to the client.

Please read over the world#setBlockState documentation inside your IDE, for the various flags available.

This isn't quite the case.

 

World#setBlockState(BlockPos, IBlockState)

calls

World#setBlockState(BlockPos, IBlockState, int)

with 3 as the flags argument. Flags are additive, so 3 is both 2 (send the change to clients) and 1 (cause a block update).

if it says it works, than sometimes it actually works. not always where you want it though. playerPosZ has a bad value.

BlockPos blk = new BlockPos(randX + playerPosX, randY, randZ + playerPosZ);

setBlockState(Blocks.dirt, new BlockPos(blk.getX(), blk.getY(), blk.getZ()), world);
