#43682: Different handling of unitflag requirements with missing target unittype Open Date: 2022-01-25 20:10 Last Update: 2022-01-30 22:12 URL for this Ticket: https://osdn.net//projects/freeciv/ticket/43682 RSS feed for this Ticket: https://osdn.net/ticket/ticket_rss.php?group_id=12505&tid=43682 --------------------------------------------------------------------- Last Changes/Comment on this Ticket: 2022-01-30 22:12 Updated by: alienvalkyrie * Milestone Update from (None) to S3_1 d3f Comment: Reply To alienvalkyrie * ...figure out whether unit type, class and class flag requirements still need to be true when in doubt – this is apparently a workaround introduced before requirement problem types (and later, tristate logic) were a thing, so it might not be necessary anymore Haven't tried it yet, but after some history-poking, I think this workaround is no longer necessary. The original workaround was apparently only relevant for whether to draw city walls based on defend bonus effects, which has since been superseded by the Visible_Wall effect. So it should be fine to make those three also give TRI_MAYBE for a missing unittype. Targetting this to S3_1, since technically – if there are any effects that are ever evaluated with an optional target unit (which I can't with certainty say there aren't) – this is a semantic change to the data file format. --------------------------------------------------------------------- Ticket Status: Reporter: alienvalkyrie Owner: (None) Type: Bugs Status: Open Priority: 5 - Medium MileStone: S3_1 d3f Component: General Severity: 5 - Medium Resolution: None --------------------------------------------------------------------- Ticket details: Unit type, unit class, and unit class flag requirements evaluate to TRI_YES when no target unittype is given. Unit flag requirements evaluate to TRI_MAYBE when no target unittype is given. This disparity was introduced fifteen years ago and apparently never documented in the code. We should probably... ...figure out whether unit type, class and class flag requirements still need to be true when in doubt – this is apparently a workaround introduced before requirement problem types (and later, tristate logic) were a thing, so it might not be necessary anymore ...if yes, figure out whether unit type flag requirements still need to not be true when in doubt ...if also yes, document the reasons in the code -- Ticket information of Freeciv project Freeciv Project is hosted on OSDN Project URL: https://osdn.net/projects/freeciv/ OSDN: https://osdn.net URL for this Ticket: https://osdn.net/projects/freeciv/ticket/43682 RSS feed for this Ticket: https://osdn.net/ticket/ticket_rss.php?group_id=12505&tid=43682
