Tube Library 2 [tubelib2]

A library for mods which need connecting tubes / pipes / cables or similar.

This mod is not useful for its own. It does not even have any nodes. It only comes with a few test nodes to play around with the tubing algorithm.

Description

Tubelib2 distinguished two kinds of nodes:

primary nodes are tube like nodes (pipes, cables, ...)
secondary nodes are all kind of nodes, which can be connected by means of primary nodes

Tubelib2 specific 6D directions (1 = North, 2 = East, 3 = South, 4 = West, 5 = Down, 6 = Up)

All 6D dirs are the view from the node to the outer side Tubes are based on two node types, "angled" and "straight" tubes.

All other nodes are build by means of axis/rotation variants based on param2 (paramtype2 == "facedir").

The 3 free MSB bits of param2 of tube nodes are used to store the number of connections (0..2).

The data of the peer head tube are stored in memory 'self.connCache'

Tubelib2 provides an update mechanism for connected "secondary" nodes. A callback function func(node, pos, out_dir, peer_pos, peer_in_dir) will be called for every change on the connected tubes.
