I'm really looking forward to this new Update, so here are my suggestions, that hopefully make it into 1.3.1(The HAX0R Update imo):
--> New Object:
Microchips // The Way they've done it in Little Big Planet 2, so that
you can carry your Ideas around
--> Gameplay/New Object:
Copy&Paste Feature for Logic
--> New Objects:
More Inputs to work within the new Logic System (Keyboard, Movement Sensor, Time of Day Sensor, so on)
--> New NPC:
The Computer Nerd/Hacker (A NPC who won't go outside of his room, needs no Light to settle down but some sort of Computer Sprite/Object must be placed)
--> New Objects:
Logic Gates (NOT, AND, OR, XOR, etc) as mentioned before
--> New Object:
Water/Lava/Honey Storage // A placeable Object which could hold up a certain amount of Water (Addition to the Water Pump System)
--> New Objects:
Lasers/Mirrors and Traps as already mentioned before
--> New Enemy:
The Bug // A Small Enemy, which has a certain radius to make your Logic not function (in a good symbiosis with the Energy System it would be fun)
--> New Object:
LED Lamp // RGB programmable Light to use for Computer Screens and so on
--> New Object:
Tone // A Block which makes sounds/tones
--> New Tool:
Mine/Trap Detector // Self Explaining
--> New Object:
Mines // You only can see your own within the Wire Mode (would be fun in Multiplayer)
--> New Weapon:
T++/T# // A Weapon that shoots One's and Zero's and could shoot through Walls with a neat effect hitting the wall
--> New Accessory:
Superhero/Matrix Wings/Coat // A Wing + SlowMoooo.... (Would blow my mind if this gets into 1.3.1)
--> New Object:
OnlineBanking // A password protected Way to store your Money (ofc hackable with Logic/EasterEgg)
Optional Things are hard to implement and the Idea need to be polished a bit:
-->
opt. NPC Stimulator (A new Weapon, an Item, a new UI? IDK) // A Way to program your NPCs, tell them to follow you and fight with you or do anything u want
-->
opt. Energy System // Water/Thermal Energy, A way to store and "harvest" (don't know a better word) energy, so on
Off Topic Suggestions/Mechanics:
--> Gameplay:
Ignition // A good way to get people rage quitting Terraria, cause their wooden House burned down (When they don't prepare with Water Storages/Water)
Hope you like it.
