Hmm, well I would recommend something like Wireless Transceivers, and they have multiple versions and upgrades.
Starting/Ending Transceiver (one sided): 1 lens, 10 wires, 5 lead/iron, and any color wrench to change color: basic transceiver that receives and sends signals to and from its correct color, multi sided transceiver at a signal sending distance of 100 blocks, and receives signals depending on the range of the multi sided transceiver range type . The one sided transceiver is activated by levers, switches or pressure pads, and will send a signal to any multi sided transceivers directly in front of it, the multi sided transceivers does not require activation, as they automatically activate once they are in range of the Starting Transceiver.
Short-Range Transceiver (multi sided): 10 lenses, 100 wires, 10 lead/iron, and any wrench to change color of transceiver: goes for 100 blocks up, down, left and right before losing the signal between transceivers. The following transceiver must not be above or bellow 5 blocks from the blocks central placing point to the left or to the right, so you can have one transceiver sending a signal to the next, but if the next one is 3 blocks above or below, it will still receive a signal , this way, you can have multiple transceivers of the same color in the world, only with different heights away from other transceivers so they won't cross the signal streams, which would be bad. The up and down sending signal and receiving signal is pin-point, and must be on the same path as the receiving transceiver, so what you send has to be on a 1x1 line up or down.
Medium-Range Transceiver (multi sided): 50 lenses, 500 wires, 10 lead/iron, and any color wrench to change color: Does everything the short range one does, only with a 500 block range.
Long-Range Transceiver (multi sided): 10 black lenses, 999 wires, 10 lead/iron, and any color wrench to change color: Does everything as the first 2, but with a 1000 block range.
Map Transceiver (multi sided): 20 black lenses, 999 wires, 20 souls of sight, 10 titanium/adamantite, and any color wrench to change color: Does what all others do, but has an infinite block range. Also, forgot to mention, the transceivers activate any electronic component in the game that stands in the way of the signal stream, so you can have 2 teleporters on each end of the map, put a Map Transceiver up, activate it with the Starting Transceiver, and both teleporters will activate if in the way of the stream and be connected to one another, if you put 3 in the way of a stream, the stream will only activate the closest one to it, so the game won't glitch out. Also blocks don't block the stream in any way.
Well, this may sound like a complicated idea, and you know what, it is. I had to draw this out for myself to actually get any of it, but I'm not done yet 'cause with more wiring types, you need stuff to wire them to, and that's why, I'm about to talk about traps, and hopefully, it'll be a much shorter explanation than the wireless wiring system I thought of.
(Maybe? Probably? Oh God.)
Magic Missile Trap: 1 Magic Missile, 4 Dart Traps, 10 wires and 2 lead/iron: So remember spelunking and exploring the dungeon after beating Skeletron, getting your hopes up for a Muramasa, or a Cobalt Shield, or even an Aqua Scepter, you open up that shiny gold chest after killing tons of enemies! And you get a consolation prize of a Magic Missile, well, now you don't have to worry, cause it won't be petty loot no more! This trap gets the manual homing abilities of the magic missile and makes it automatic! This trap is able to fire 4 homing magic projectiles at once at an enemy who dares to cross your trap, dealing 20 damage per individual fired shot and with a cool down rate of 10 seconds and a relatively slow speed, this gives the Magic Missile the love it should get as dungeon grade loot, even if its slow... still it'll chase down any enemy it fires at, that"s something, right? Also, any other weapon like the magic missile should get to be used in the same manner, but obviously as an upgrade to this trap, so if anyone can think of an upgrade scale to the traps, I'll email you some cookies.
Blue Moon Swing Trap: 1 Blue Moon, 1 Actuator, 10 chains, 4 lead/iron: Well, this is a weapon that I believe is not used as much and is sometimes considered petty loot, and please correct me if I'm wrong, but hasn't anyone ever wanted or tried to take one of those Spike Ball traps from the dungeon? Well, the Blue Moon Swing Trap basically gives you the same trap, only with a Blue Moon. If you have any extras lying around, this trap can be good for a type of early defense on Hard Mode, even if it outputs 23 damage per hit, it'll have a decent knock back, and hitting it with a hammer changes the swing direction. Again, anyone who would like to think of more advanced blueprints using things like a Flairon as upgrades, please do and I'll send you some *cake! *The Cake is a lie
Spider Trap: 1 Spider Staff, 2 Outlet pumps, 6 lead/iron: So, ever thought of being a Summoning type character for a run, but feel rather bored watching the minions toy with their prey? Well, besides minions being great servants, they also make great house sitters, especially spiders. So go out and explore as much as you want, cause while your away, the those eight-legged buggers will greet the neighbors while you're out. The Spider Trap spawn 3 Arachnids to defend your house and they last around 5 minutes for each wave, if the trap is activated while the spiders are out, nothing will happen. And the best part? Since you don't see the spiders you won't be tempted to burn your house down with the flames of the Holy! You can also make variations to the design using other staffs as the traps base staff if you like, in case you have a bit of arachnophobia.
Turret (7 Different Ones):
Lihzahrd Power Cell (Electrified Debuff)
Living Fire Block (On Fire! Debuff)
Living Frost Fire Block (Frost Burn Debuff)
Living Cursed Fire Block(Cursed Inferno Debuff)
Living Ichor Fire Block (Ichor Debuff)
Living Demon Fire Block (Shadowflame Debuff)
Living Ultrabright Fire Block (Blackout Debuff)
The Recipe: 100 of any of the Living Fire Blocks or 20 Lihzahrd Power Cells for the Electric type, 20 iron/lead, 4 Outlet Pumps except for the Lihzahrd Power Cell recipe which will replace the Pumps with 100 Wires. The Turrets purpose is to stand still and kill everything that gets close, it will do the same thing as the Tesla Turret from Martian Madness, only with their special debuffs for specific types if defense. For Players, It would be best to use the Ichor Turret or the Ultrabright Turret, while the others can be used for home defense against mobs.
Electric Fence(500 Blocks): 10 Lihzahrd Power Cells, 500 wires, 100 chains: This one is simple, I swears it. It's a fence, it does the Electrified Debuff on anyone who touches it, and has the same block physics as the Smoke Block. In other words, any mob that walks into the fence will get shocked. Moving On.
B.O.O.M.(Bunnies On Overpowered Minecarts) Cart Rail Gun and Ammo:
B.O.O.M. Rail Gun: 150 Booster Tracks, 100 Wires, 50 Actuators: This cannon has a use time of 10, and the velocity of a High Velocity Bullet. It has the same size as the other cannons due to the Actuators allowing the tracks to be stacked over and over 150 times.
Ammo (B.O.O.M. CART) : 1 Minecart, 3 Explosive Bunnies, 50 Wires, 5 Fireworks (Any Color): This Innovation in minecart technology brings the best of Exploding Bunnies, Explosions, Fireworks and, of course, Minecarts! Dealing a whooping 600 damage per loaded cart, it makes you wonder, that up there in NPC heaven 1000 Demolitionists are nodding their heads in approval to this masterful reworking of Terraria's Fauna, and the unforgiving explosive nature of dynamite. Oh, Iv'e just gotten word that "killing Bunnies is cruel, period" by T.E.T.A. (Terrarians for the Ethical Treatment of Animals). So while I cannot endorse the use of this kind of Cannon Ammunition anymore, I can leave the instructions up for public opinion and "research" on the do's and don'ts of Ethical Bunny Treatment.
So those are the Weapons I could think of as house defense, maybe I'll edit this later with more stuff, idk. If anyone wants to come up or improve any of the concepts for all the stuff I've written down, by all means go ahead, In the mean time I'll just think of more stuff, and come up with decent names for them, like the Ichor Turret could be called the Golden Shower or something, be impressed if a name like that got in the game. Still If you think there's anything I could add, that would help, so thanks for reading.
[DOUBLEPOST=1441155189,1441155074][/DOUBLEPOST]Well I'm impressed.
