Hello!

 

I ran into very strange issue while trying to sync TE from server to client AGAIN. But this time it's really magic. When I call tsTE.activate() everything is in sync and works fine, but when tsTE.deactivate() is called - value on server side is changing, but it doesn't on client side, although received packet is fine. So, the client thinks "isMoving" equals "true" no matter what.

Here's some code:

Method from which I call my update method:

@Override
public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ) {
    if(!worldIn.isRemote)
    {
        ...
        TileEntity te = worldIn.getTileEntity(pos);
        if(te instanceof PistonVesselTE) {
            TimeSymbolTE tsTE = (TimeSymbolTE) worldIn.getTileEntity(((PistonVesselTE) te).getMainBlockPos());
            if (tsTE.isStructureComplete())
            {
                tsTE.activate();
            } else {
                if(tsTE.isMoving)
                    tsTE.deactivate();
            }
        }
    }
    return true;
}

 

TileEntity's methods:

public void activate()
{
    if(isMoving)return;
    if(world.isRemote)return;
    isMoving = true;

    ...
    markDirty();
    world.notifyBlockUpdate(pos, world.getBlockState(pos), world.getBlockState(pos), 3);
}

public void deactivate()
{
    if(!isMoving)return;
    if(world.isRemote)return;
    isMoving = false;
    
    ...
    markDirty();
    world.notifyBlockUpdate(pos, world.getBlockState(pos), world.getBlockState(pos), 3);
}

 

TileEntity's NBT methods:

@Override
public void readFromNBT(NBTTagCompound compound) {
    super.readFromNBT(compound);
    if(compound.hasKey("isMoving")) isMoving = compound.getBoolean("isMoving");
    if(compound.hasKey("structureChecked")) isMoving = compound.getBoolean("structureChecked");
}

@Override
public NBTTagCompound writeToNBT(NBTTagCompound compound) {
    compound = super.writeToNBT(compound);
    compound.setBoolean("isMoving", isMoving);
    compound.setBoolean("structureChecked", structureChecked);
    return compound;
}

 

TileEntity's Sync stuff:

@Override
public NBTTagCompound getUpdateTag() {
    return writeToNBT(new NBTTagCompound());
}

@Override
public SPacketUpdateTileEntity getUpdatePacket() {
    NBTTagCompound nbtTag = new NBTTagCompound();
    this.writeToNBT(nbtTag);
    return new SPacketUpdateTileEntity(getPos(), 1, nbtTag);
}

@Override
public void onDataPacket(NetworkManager net, SPacketUpdateTileEntity packet) {
    super.onDataPacket(net, packet);
    this.readFromNBT(packet.getNbtCompound());
    ModMain.logger.info("Received packet: "+packet.getNbtCompound().toString()+", side: "+world.isRemote);
    world.notifyBlockUpdate(pos, world.getBlockState(pos), world.getBlockState(pos), 3);
}

 

In debug info, everything is fine. I get the correct isMoving=0b in NBT with world.isRemote=true

if(compound.hasKey("isMoving")) isMoving = compound.getBoolean("isMoving");
if(compound.hasKey("structureChecked")) isMoving = compound.getBoolean("structureChecked");

???????

Is this on purpose?
