Building Redstone

Critical: Block Placement Order

Support blocks FIRST, then dependent blocks! Blocks drop as items if support doesn't exist.

WRONG: 1.wire 2.button 3.blocks → Wire breaks! RIGHT: 1.platform 2.walls 3.wire 4.button

Attachment Rules

Block Support Location

redstone_wire, repeater, comparator, carpet, pressure_plate Y-1 (below)

redstone_wall_torch, button, wall_sign Same Y, offset by facing

Wall attachment facing: east →block at X-1, west →X+1, north →Z+1, south →Z-1

MCP Tools

build(commands=[ "/fill X Y Z X2 Y Z2 stone", # 1. Support "/setblock X Y+1 Z redstone_wire", # 2. Redstone "/setblock X+1 Y+1 Z stone_button[facing=west,face=wall]", # 3. Attachments ])

Logic Gates

NOT: [in]→[block]→[torch]→[out] — Torch inverts signal OR: Merge two wires at same block AND: Two torches→junction block→inverting torch→output XOR: Two comparators in subtract mode, OR their outputs

See gates.md for implementations.

Memory Circuits

RS Latch: Two torches in feedback loop (Set/Reset) T Flip-Flop: [in]→[dropper↔dropper]→[comparator]→[out] — Toggles state

Timing

Repeater Clock (3 minimum):

build(commands=[ "/setblock X Y Z repeater[facing=east,delay=1]", "/setblock X+1 Y Z repeater[facing=south,delay=1]", "/setblock X+1 Y Z+1 repeater[facing=west,delay=1]", "/setblock X Y Z+1 redstone_wire", ])

Hopper Clock: [hopper→hopper] with comparator. Timing = items × 0.4s

Piston Door (2x2)

build(commands=[ "/setblock X Y Z stone_bricks", "/setblock X Y+1 Z stone_bricks", "/setblock X-1 Y Z sticky_piston[facing=east]", "/setblock X-1 Y+1 Z sticky_piston[facing=east]", "/setblock X-2 Y Z redstone_wire", "/setblock X-2 Y+1 Z redstone_wire", ])

Block States

repeater[facing=north,delay=1-4,locked=false] comparator[facing=south,mode=compare|subtract] piston[facing=up,extended=false] sticky_piston[facing=east,extended=true] observer[facing=north] # watches that direction lever[face=wall,facing=north] stone_button[face=wall,facing=east]

Signal Properties

Method Distance Speed

Dust 15 blocks 1 block/tick

Repeater chain Unlimited 1-4 ticks each

Observer chain 15+ Instant

Component Delay

Repeater 1-4 ticks

Comparator, Torch 1 tick

Piston 0-3 ticks

Observer 2 ticks
