Hy, everyone! I have a problem)

 

I create simple TileCounter and BlockCounter.

If I click on different sides of the block, then my counter value is updated. And server displays correct value, but client don't.

How to sync it?

 

P.S. I'm a beginner in modding.

P.S.S. I understand much better if there is a  example.

        super(Material.IRON);

        this.setUnlocalizedName(name);
        this.setCreativeTab(CreativeTabs.BUILDING_BLOCKS);

        if (!world.isRemote)

            if(tileEntity != null)
            {

Looks like you're not syncing the updates to the server. You'll want to look into this https://mcforge.readthedocs.io/en/latest/networking/simpleimpl/

 

Don’t use ITileEntityProvider, it’s legacy Minecraft code. Just override hasTileEntity(IBlockState) and getTileEntity in your block class
