[Forge 1.10.2] How to create a container that have moving progress arrow and send packet to client, server and player?

Does anyone know how to do that?

If your tile entity is processing stuff on the server world, you only need to send packet to those clients that are able to see the progress. You can make a boolean in tile entity that will indicate whether it should send the progress. Then in the container class, you pass the tile entity to its constructor and set this boolean flag to true. Then in tile's update() method, you check this flag and send a packet containing the progress value to the players that can see the progress. When container is closed, you set the flag to false, so there are no unneeded packets sent.

Look at BlockFurnace for an example.
