FW Advance Slot Properties

From SLeague

(by William Keenan)

An authoritative guide to the unique characteristics of the 'advances slots' that intertwine to make the Civ2 technology tree.

(this is Version 1.2 of the article, first published in May 2000 on the original S-League site. The section on version changes has been omitted as it had links to other documents)

[edit] The Advances Slots

Creating an engaging scenario or mod-pack for Civ2 will in all likelihood involve modifying the advances or technology tree as set out in scenario's rules.txt file. The tree itself can be modified, however a large number of 'slots' (row position in the table) have unique characteristics and care must be taken to ensure that tribes begin with and if appropriate discover technologies appropriate to their circumstance.

[edit] How to Use this Chart

Slot is the order in which the technologies are listed in the rules.txt. The events.txt file sometimes refers to technologies by slot number.

Code is the abbreviation used to refer to the technology slot in the rules.txt file.

Trigger Effects of Discovery are all hard coded in the software and unchangeable by scenario designers. Effects that are event driven, like winning the game by discovering Transcendence, have been purposely excluded from this chart.

References to other parts of the rules.txt file (improvements, trade items, units) and support files (cities.gif, people.gif) always refer to the appropriate slot in the given section not necessarily the named item. For example if your renamed temples to cathedrals and cathedrals to museums then the discovery of Theology would make museums more effective rather than cathedrals.
