Door Types
Start with 2x2 piston doors, then move to flush wall doors and floor hatches. Each teaches timing, inversion, and compact routing.
Timing Basics
Use repeaters to synchronize top and bottom piston pairs. One-tick timing differences can break the open-close sequence.
Input Methods
Buttons are clean for temporary access. Levers for permanent modes. Pressure plates work for hidden survival entrances.
Compact Wiring
Route signal vertically and separate input and output lanes to avoid accidental backflow and crosstalk.
