I want a gui I've created to open when a block I've made is right clicked(onBlockActivated), but I can't find any suitable methods. The openGui method in the EntityPlayer class requires a gui id, but I have no idea what that is. I've looked at the methods the vanilla gui's use, but they require a minecraft instance that I don't know how to create. Does anyone know how to open a new gui in Forge?

There are many tutorials out there for this.

As for the id, its w/e the hell you set, I recomend something logical like 1 for your first gui, 2 for the 2nd and so forth...

It doesn't "require" an ID if you only have one gui. I think you just have to make sure you set up your GuiHandler correctly and the it will be fine.

I think I've figured it out, but when I right click on my block to open a Gui, the command window says "[WARNING] [ForgeModLoader] A mod tried to open a gui on the server without being a NetworkMod" and the gui fails to open. I have the "Mod", "NetworkMod", and "SidedProxy" annotations set up according to the google doc on the first block tutorial page on forge wiki, and I set up the GuiHandler (implementing IGuiHandler and overriding the methods) according to the Containers and Gui tutorial on the wiki. My mod works fine otherwise (the blocks and items I created work correctly) How can I make my mode a NetworkMod? I've searched for solutions, but I can't find any using google.

 

Also, the command window says that my textures aren't preloading. How do I preload textures?

To remotely open a GUI (from a block in the world, for example) you need to be an @networkmod

I have this line of code right above my main mod class (I have a PacketHandler set up):

 

@NetworkMod(channels = { "Custom Music" }, clientSideRequired = true, serverSideRequired = false, packetHandler = PacketHandler.class)

 

Do I need to do something more to get this to work?

No that should be sufficient.make sure your running a recent forge..

I've had that there all along, and it still wasn't working. I don't know what else I can do. It still says that my mod isn't a networkmod.

 

Also, the mcp recompiler is using the 1.6 source rather than the 7 source, so I can't use strings in switches. How can I change which source the mcp recomplier uses?
