Introduction

What is a command?

A command is a beam that has "Commands" that make it extend/retract and so forth, The command beam has many uses, From being a Hydraulic arm to a destruction tool, There are plenty of ways to use a command.

Basic information

I will start off by using the basic sectional organization, which is..

Node 1, Node 2, Extension/Contraction Rate, Maximal Contraction, Maximal Extension, Contraction Key, Extension Key,  Option
Example:
1,       2,        0.1,            1.0,                 3.0,              1,              2,           i

Node 1 - The node where the command beam starts
Node 2 - The node where the command beam ends
Rate of extension/contraction - How fast the command beam moves
Maximum contraction - The shortest length that the command beam will try to be, as a proportion of its startup length
Maximum extension - The longest length the command beam will try to be, as a proportion of its startup length
Contraction key - A number representing the function key needed to compress the command beam. More than one can be controlled with the same key. (see below for keymap)
Extension key - The key used to extend the command beam.
Option flag (optional) - (i) makes the command beam invisible. (r) makes the command behave like a rope or a winch (no compression strength). (n) should be used as a filler when a description field is needed (p) program: makes the command extend or retact fully with the push of a button

In the RoR Editorizer, the beam for commands will be Green (Or whatever color you specified for the command beam).

Uses

A command has plenty of uses, In fact, many vehicles in the Rigs of Rods repository host vehicles with Commands in it. Some of the things you can do with commands..
