How can I write a command into a newly spawned command block


Recommended Posts

Hello, I am spawning a command block into the world with the following:

mc.world.setBlockState(blockPos, blockState);

which works just fine.

if (blockState.getBlock() == Blocks.COMMAND_BLOCK){
                    System.out.println("String thats passed in: " + commandLine);
                    setCommandString(mc.world, blockPos, blockState, commandLine);
private static void setCommandString(World world, BlockPos pos, BlockState state, String command){
        System.out.println("SetCommandString String: " + command);
        TileEntity tileentity = world.getTileEntity(pos);
        System.out.println("TileEntitySet: " + tileentity);
        if (tileentity instanceof CommandBlockTileEntity) {
            CommandBlockTileEntity commandblocktileentity = (CommandBlockTileEntity) tileentity;
            CommandBlockLogic commandblocklogic = commandblocktileentity.getCommandBlockLogic();

            world.notifyBlockUpdate(pos, state, state, 3);
//            CompoundNBT nbt = new CompoundNBT();
//            nbt.putString("Command", command);
//            commandblocklogic.write(nbt);
//            commandblocktileentity.write(nbt);

As you can see here, I am trying to "setCommand", however when I check the newly spawned command block, it has nothing written inside of it. Any thoughts on this?
