How it works

A stone button stays pressed for 20 game ticks (an oak one 30); the lamp goes out 4 ticks after that, the lamp delay.

  1. Pressing the stone button creates a timed high input and then releases it automatically.
  2. Watch the button or wire to measure the underlying pulse; a lamp remains lit after the wire turns off.

Timing

Measured at the output: a pulse of 24 game ticks (1.20 s) per event.

Inputs and outputs

  • Inputpress (x 0, y 0, z 0)
  • Outputlit for 24 ticks (x 3, y 0, z 0)
