Can somebody explain (without making me look at MC's source, as I don't understand any of it), what I need to do to make my robot entity move around and have an inventory/gui/container/whatever?

I can just about do the rest, and if I can't, I'll just make something up.

You need to understand the MC source code to be able to code in the MC source code. 

Well, I get most of it. I just don't understand entities much. Am I doing it right so far?

Depends.  What will it do?

Just roam around and do the solar panel physics to charge batteries. How would I do the opening of a gui from an entity? Would it be in an entityActivated()?

Yep.

Copy and paste the AI from some mobs to make it wander.

Have you tried decompiling 1.3? The code obviously won't be directly copy/pasteable, but Villagers now open a GUI with a Container.

I retried putting UE into there and I just ran into tons of errors messages.

 

Also, 1.3 seems to have world.isRemote and I think that variable is pretty useless considering the fact that it's ALWAYS remote/SMP?

Actually, as I predicted, Mojang didn't come through with the SSP/SMP merger. Instead of the client being a dummy, they just made the client speak in Packetese. By that, I mean all communication in SSP is now dealt through packets. This means the client can now function as an SMP server, but it doesn't actually make SSP mods SMP like we we were promised/lead to assume.

Actually they never said SSP mods would be SMP capable (which would be impossible without logic in the mod to know on which side to run on), rather they said that SMP mods would be SSP capable, which is true.

So I have to write a SSP and SMP?!?!

Yup. Both in minecraft.jar clent

Is it easy?

Is there some secret?

What needs to change from server to client?

Actually you write just SMP, the SSP part is the SMP part + graphical stuff now.  Unlike before where they were two different code basis.  So yes, it is a lot easier.

Oh. So no weird packet sending/recieving? Or do I just do the sending?

You gotta handle both, same in single player now. 

Single player 'is' just multi-player, but with a single person.

Yeah. OK.
