Does any1 know when is the 1.3.1 being scheduled? October? November? December? New Year? There are tons of ideas and i'm sure some regular fixes against Steam Cloud or other things will be incorporated, but would love to know some more details on the schedule. Also on the topic, i concur on the previous suggestions (and perhaps some new ones):
1. More wire controls - additional wire color, perhaps one wrench for placing all wire types?
2. Wireless transmission - Transmitters that send energy signals in a defined direction for a set distance. Most likely go through blocks, but in a straight line so you have to put the receiver at the same height/width.
3. Topographic measurement laser - Some kind of laser tool, that when activated would send a harmless laser in a straight line for infinite amount of blocks (or higher than the wireless transmitters). This would help in putting down transmitters across the map or digging/building against a fixed height/width. This could be a steady laser that lasts for a second and goes through blocks (having 1 second trigger would make it work indefinitely). Maybe some mirror blocks that could change direction of laser? Multi color laser so one could make interesting things with it?
4. Wire color changing blocks - The easiest way to attain this is to have a special block that sends the signal through when hit with a signal from a different wire color. Different colored wires would have to meet at the Wire color changing block. For example:
...............R...G
RRRRRCBBB+BB+BBBCRRRRR
...............R...G
R - Red wire, B - Blue wire, G - Green wire, C - Color change block, + - intersection for Red and Blue wires and Green and Blue wires.
Sufficient to say that it would allow help bypassing difficult wiring at some places if no wireless transmission is implemented.
5. Logic blocks - Due to Terraria wiring system being signal based, not current based, a logic block would be a discerning into different directions (wire colors) a signal depending on its state. For example: Red wire hits the logic block and depending on the setting and outputs a signal in one of the two other wires. This would have to be done with at least 2x2 size:
+-----------+-----------+
|B&G.....|Red......|
|output..|changer.|
+-----------+-----------+
|Red......|B&G.....|
|input....|output..|
+-----------+-----------+
In this setup the "active output" could glow and red wire wouldn't cross each other. This allows one color to be used as input and changer (for switching between outputs) and binding two other wire colors to each output.
Having bigger Logic blocks would be even more interesting (3x3):
+-----------+-----------+-----------+
|Red......|GB.......|Red......|
|output..|output..|changer.|
+-----------+-----------+-----------+
|GB.......|...........|GB.......|
|output..|...........|output..|
+-----------+-----------+-----------+
|Red......|GB.......|Red......|
|input....|output..|output..|
+-----------+-----------+-----------+
In this setup one wire is used to receive the input signal on lower left and change the chosen output in the upper right. Middle blocks would serve as the output for other wire colors, when upper left and lower right could be used with the same color as the input (not connected together so can be used).
6. One additional thing, probably not mentioned anywhere: Introduction to pipes - Enhance pump mechanics in order to use pipes not wires (could act the same way as wires or be solid blocks). Having pumps use the signal based wiring is a bit off, limiting the use of wires if you have to use pumps. having pipes could also mean intersections (sending liquids to multiple destinations), fountain sprays (would require regular amounts of liquid, making A MUST to create a circular piping system for them) and having the pumps (inlet and outlet) contain an on and off state (turning them on with wiring) to work through liquids. This one is probably the toughest to code as it would change a lot in the game, but i think an interesting idea.
