Description

[[--- Retiring ---]]

Hey Ladies and guys, I'm slowly but steadily retiring from my modding hobby, so the mod is EOL and will not be under active development as of MC1.21.1. Checkout the references section below for alternative mods created by the community, and I'd be glad to see if some of the mod features are re-used somewhere. Cheer's, WilE.

[ Note: The first Fabric version of the mod is for Minecraft 1.19. Files are then named redstonepen-<minecraftversion>-<forge/fabric>-<modversion>.jar ].

Adds "one pen to draw them all" - and helps with simpler Redstone handling.

Block Signal Connectors: Especially for compact wiring it is desirable to decide weather a Track shall power the block underneath or not. Therefore the Pen-Tracks do normally NOT connect to the block they are drawn on. To change this, simply add an explicit connector by clicking the centre of a Track with a Pen (see the round blob in the image). Tracks do intentionally not pass indirect power (through blocks) to other Tracks, so you can power said blocks from independent routes without interferences:

Block Signal Connector

Redstone Quill and Pen Items

Craft and use them to draw or remove thin Redstone Tracks. Multiple independent tracks through one block space are possible. There are two versions:

- The Redstone Quill uses Redstone dust directly from your inventory.

- The Redstone Pen stores Redstone in the item, and can be refilled in the crafting grid with Redstone Dust or Redstone Blocks.

- Both allow to inspect the current signal of a block, track, wire, or device by sneaking while you hold the pen/quill and look at the block of interest.

- Both do not destroy blocks when left-clicking, except blocks with no hardness (like grass, repeaters, or comparators).

Redstone Relays

Relays are like redstone powered "solenoids" that move builtin Redstone Torches back or forth, so that they re-power ("re-lay") Redstone signals to 15. They can be placed on solid faces in all directions. Output is only to the front, inputs are at all sides except from above. The internal mechanics ("relay types") define what happens at the output side when the input signals change (relay, invert, flip etc). Relays also detect indirect power from blocks they are placed on, and can therfore be used to pass Track signals through blocks.

- Redstone Relay: Straight forward Input-On-Output-On relay. Different from a Repeater it has no switch-on delay, but instead a switch-off delay of one tick (redstone-tick=100ms).

- Inverted Redstone Relay: Input-On-Output-Off relay. Switch-on delay 1 tick, no off delay.

- Bi-Stable Redstone Relay: Flips when detecting a off-to-on transition at the input ("rising edge"; input off->on --> output changes).

- Pulse Redstone Relay: Emits a short pulse at the output side when detecting a off-to-on transition at the input ("rising edge").

- Bridging Relay: A Redstone Relay allowing to cross tracks. It forwards power back to front like a normal Relay, and has an additional independent wire left-to-right.

- Redstone Logic Controller: PLC-like redstone signal I/O block. Programming is simplified with math expression assignments, e.g. "R = G AND (Y OR B OR U XOR D)" or "Y = (G > 4) AND (B <= R)". Ports are in all directions (lateral by color: R,G,B,Y, vertical (U=up, D=down), and support "comparator override" input modes. Provided elements known from PLCs are timers (TON, TOFF, TP), edge triggers, counters, arithmetic functions like minimum, maximum, mean, limiting, and some auxiliary functions like game time (ticks) day time, random number, inline conditional (R = IF(condition, true-value, false-value) ), etc. Brief help reference is included as tooltips at the left side of the GUI. More details and examples about the RLC on the github here.
