"A mod tried to open a gui on the server without being a NetworkMod" error

[AskHow1248]

I've been making a block with a gui following this video:

but when I start minecraft and try to open the gui, I get a message in the eclipse consle saying "A mod tried to open a gui on the server without being a NetworkMod".  I have no idea what this means, since I have a @NetworkMod annotation.  I can supply my code (slightly different from the videos) on request.  Any help will be appreciated.

Do you have

 

@NetworkMod(clientSideRequired = true, serverSideRequired = false)

 

Or do you have

 

@NetworkMod(clientSideRequired = true, serverSideRequired = false,
clientPacketHandlerSpec = @SidedPacketHandler(channels = {"MyMod"}, packetHandler = PacketHandlerClient.class),
serverPacketHandlerSpec = @SidedPacketHandler(channels = {"MyMod"}, packetHandler = PacketHandlerServer.class))

 

?

I have @NetworkMod(channels = {"TM"}, clientSideRequired = true, serverSideRequired = false, packetHandler = TMPacketHandeler.class), which is what the video has (It works fine in the video). (I'm in 1.6.4)

Did you included your mod instance?

@Instance(your_modid)
public static YourMod instance = new YourMod();

[AskHow1248]

I included it, but I didn't intinalize it.  I will now.

Don't do that. The ModContainer initializes the instance field automatically when the mod is instantialized. If you put some there with static initialized it will be overwritten.

[AskHow1248]

Fixed.  The error happens if I intinalize it.

[coolAlias]

Odd, I've never had any problems initializing the mod instance like that. Surely your error was caused by something else, but at least it's solved.

 

I wasn't aware that we're not supposed to initialize them, as I have been since I started modding with no ill effects, but if it's just doing the same work twice, well, no need for that

This is all done in FMLModContainer$processFieldAnnotations(...).
