Node detector

Introduction

Node detectors detect a node in front of them. You can change their options by right-clicking it for an options formspec. If it detects a node, it sends a mesecon signal (or a digiline signal).

Options

Node detectors have 3 options. After edtiting them, press the "Save" button to save the settings.

Node to scan for

This is pretty self-explanatory. It selects the node it is trying to scan for. Leave it empty to scan for any node.

Distance

This is the distance (in nodes) in front of the node scanner that it will scan for.

Digiline Channel

This is the digiline channel that the scanner will send a message when it sees something. You can leave this empty if you don't want any digilines.

Diagram

Imagine this is the scanner -> █

In this diagram, the scanner is scanning 1 node in front, for ▓ nodes.
