Help with PacketDispatcher error

[jamiemac262]

okay so i've been updating the Sim-U-Kraft mod from 1.6 and intend to make it SMP later aswell, omong the 1,088 errors i have left i found this bit of code:

    for (World w : MinecraftServer.getServer().worldServers)
                    {
                        if (w.loadedEntityList.size() > 0)
                        {
                            serverWorld = w;
                            currentWorld = ModSimukraft.getSavesDataFolder();
                            ModSimukraft.log.info("CommTH: Startup - set serverWorld/currentWorld");
                            ModSimukraft.resetAndLoadNewWorld();
                            PacketDispatcher.sendPacketToAllPlayers(PacketHandler.makePacket("", "gamereset", ""));
                            break;
                        }
                    }
                }
                catch (Exception e)
                {
                    serverWorld = null;   //will exception until first player has spawned!
                }

 

i am quite new with forge and frankly i havent the foggiest what this does or where to begin to go about fixing the errors here:

 

PacketDispatcher cannot be resolved

 

and

 

The method makePacket(String, String, String) from the type PacketHandler refers to the missing type Packet250CustomPayload

 

could anybody tell me what i need to change to fix the errors?

 

sorry if this comes across as a vague question, if you need any more information ask for it and i will provide it
