I'm thinking of building a semi-automated defense system using a series of Sticky pistons, hoppers, droppers, normal pistons, dispensers, and a skeleton farm. I'm on the design phase now, but plan to build, test, and implement it into my Ultimate Gregtech server. Does anyone have any that they use that they can show off or any plans of their own? While I plan to use some mod items, I'd like to be able to design the entire thing to be usable in vanilla, though movement of Dispensers will be the hard part.

Since you listed a bunch of items, why don't you explain your initial theory and allow us to build on from there.

Basically, I'd farm skeletons for arrows, then use a series of hoopers to transport them to an underground Dropper, which will drop them into a dispenser. The Dispenser would be able to be pushed up to 1 block above the ground using multiple pistons, and would then be loaded with arrows, since you can't move them with arrows. Once a flip was switched, it'd be undone and go back into hiding.

One problem with that: dispensers can't be pushed by pistons, and also for that to work you'd have to have exposed wires. Just have some kind of walls or battlements or whatever with them in, with pistons with blocks covering them instead.

Can they not be pushed even when they are empty? If not, I could do a different, much easier version and just drop the ground around them.

Force fields man. Nothing else to do with all that monazite.

Though, you also have to consider if someone is sprinting across that trip wire. I don't know how fast redstone -> push piston -> shoot

Unless this is an active defense, not automated.

Force fields, as nam has stated, are brilliant.
They are almost impenetrable, can kill or not kill whoever you like, armour or no armour, and can be any size you can power. If you have self-sufficient power within, you will be indestructible from outside sources.

I was hoping to have little self defense stations stationed through out the my yard as an anti-mob/player system. The forcefields, while nice, would probably be just for my major systems, same thing with the more elaborate systems.

To be better prepared don't be an idiot and just plop down some solar panels that could be taken out from above the field and robbers just spam the field to make the buffer of eu runs out. A couple of dozen of Thermal generators isn't going to cut it for "backup" power on a hardcore pvping server. You need to make many different power generations so the robbers will have to take more time to tear the grid of power. You need to have it so it's too long to ever drain the entire power grid so you can hop back on and repair and improve the security of your base.

Just use something slef-sufficient such as a bio farm.

True that's would work but once the farm is halted then your biofuel boilers will be running on empty. If you pair this with say Fuel then once the boilers do run out of bio then a second duct can pump in fuel into them before the final burn cycle is up. Boilers are actually a good way to just have multi fuel sources ready and "loaded" so as long as the robbers don't get to them your in good shape.

I am not on a PVP server, I'm actually on a server with 2-3 friends, no griefing or unasked for PVP. I just like the idea of defensable positions. I might try the TNT cannon idea, I can farm gunpowder via creepers easy enough. Hmm...Make obsidian markers and just blast away at the ground.

Item frames on dispancers (and walls so they dont look out of place) . Or use a piston to pull up a block that in fornt of the dispancer so the wall basicly opens and fires.

Splash potions of harm and posion

You can even build a automatic brewing system to keep them stocked.

Hmm, I'll have to look more into it. I appreciate the feedback. Anyone have a defense system they use that isn't a normal one?
