I am trying to make a tile entity that works like a gear shaft. The shaft is meant to connect to other shafts when I place them next to each other. I've set up the onNeighborBlockChange function to make adjacent shafts connect when you place one, but for some reason only the one I placed updates. A bit of debugging has told me that the shafts are updating correctly on the server side, but not on the client side. I have packet handling set up in the tile entity, and it's being updated correctly in the onDataPacket function, so I don't know why it's not updated correctly when rendering. Here is my code (I've only included the parts I think are important):

im at my tablet so i cant help to much you, but what about world.updateBlockForRender?

 

I just tried that, it didn't make any difference.

After changing the tile entity's state, you need to call the block's markBlockForUpdate method -- this ensures that the state is sent to the client and the block is re-rendered. You should also call the tile entity's OnInventoryChanged method, otherwise the state might not get saved to disk.
