I am making a pipe mod. The blocks also use a block entity. I added boolean properties for north, south, east, west, up, down and wrote to them on the setPlaced method. In my blockstate json, I use a multipart model to apply the pieces of the pipe to each side. 

It does not seem to be working. How can I synchronize the new blockstate values so that my pipe gets rendered properly?

Show your code.

I am using BlockState.setValue on the overriden setPlacedBy method. The values are getting set, i added some logging there. I am using BlockStateProperties.NORTH, SOUTH, ... .

I also made sure they are added in the createBlockStateDefinition method and registerDefaultState in the constructor.

this is the blockstate:

{
    "multipart": [
        {
            "apply": { "model": "cables:/block/cables/without_connections" }
        },
        {
            "when": { "north": true },
            "apply": { "model": "cables:/block/cables/connection", "uvlock": true }
        },
        {
            "when": { "west": true },
            "apply": { "model": "cables:/block/cables/connection", "y": 90, "uvlock": true }
        },
        {
            "when": { "south": true },
            "apply": { "model": "cables:/block/cables/connection", "y": 180, "uvlock": true }
        },
        {
            "when": { "east": true },
            "apply": { "model": "cables:/block/cables/connection", "y": 270, "uvlock": true }
        }
    ]
}

Please show this code.

blockState.setValue(SOUTH, true)

this is all there is in the setPlacedBy overridden method.

That achieves nothing. BlockState is immutable. You should override getStateForPlacement instead and return the modified BlockState.

That sucks. I have some logic on the tile entity that will be used to get those values. Do I really have to move that logic out of the tile entity? I assume the tile entity is placed after that method.

I am not sure how that is at all relevant?

I.e i have to move that logic out of the tile entity because the tile entity has not been placed yet when getStateForPlacement is being called.

Why are you duplicating data? Either store the info in the BlockState or in the TileEntity. Don't do both.

the logic I am referring to gets the Directions where other pipes that can be connected are. To set the right values in the block state, I would have to move that logic out of the tile entity so i can use it from the block. Preferably, I should move it to the block class. Is that correct?
