[Freeciv-Dev] [bug #15373] add health effect to default/effects.ruleset
Follow-up Comment #1, bug #15373 (project freeciv): I've actually been playing default rules with illness enabled for a while, for giggles. I'm finding it effectively just reduces the max city size with no Sewer System; the default increase in plague chance with size is very steep (size 7/8/9 = 0.0%, size 10 = 11.0%), so I never even get to size 11 (I don't have Sanitation yet). I think this slope dwarfs any effects from pollution/trade. So, the default setup seems uninteresting enough that it's not worth being able to switch it on; I assumed that the parameters needed more tuning. I've got Health_Pct effects Aqueduct = 30, Sewer System = 20, Cure for Cancer = 5; I can't remember where I lifted these from now, but I think the parameters in the [illness] section of game.ruleset are probably what needs tuning. I imagine it also gets more interesting if you have buildings specifically for this like Hospital. Perhaps syntron's experimental ruleset (patch #1236) has better tuned parameters; I haven't looked yet. (It's perhaps a shame that that isn't in 2.2.0 to play with.) Also the effect code on [http://freeciv.wikia.com/wiki/Math_...] is wrong, the name of the effect is Health_Pct and not Health. Fixed. ___ Reply to this item at: http://gna.org/bugs/?15373 ___ Message sent via/by Gna! http://gna.org/ ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev

When I first made this, I used some spreadsheets in order to choose parameters, and hoped for parameters that will prevent cities of effectively growing bigger than 8 without improvement. I no longer have those spreadsheets, but my original ruleset is found here: http://forum.freeciv.org/viewtopic.php?t=5721 The patch is, of course, irrelevant. Also, I don't know how much the code had changed since my original contribution, so it might be relevant any more.

Follow-up Comment #2, bug #15373 (project freeciv): My error - see patch comments; I also reduced the base propability from 25% to 20% the patch is only for trunk; if a fix for S2_2 (2.2.1) is needed, I will try to reduce the number of changes to the code == patch comments == update illness / health * for testing the calculations I used floating point numbers but within the freeciv codebase integers are used - rounding errors (no illness up to size 10); calculate the values using floats * move the check for illness_min_size into city_illness() * reduce illness_base_factor from 25 to 20 * add health effects: aqueduct: 50 sewer system: 30 cure for cancer: 20 = reduction by up to 80% (100%) (file #8116) ___ Additional Item Attachment: File name: 20100215-trunk-update-illness-health.patch Size:7 KB ___ Reply to this item at: http://gna.org/bugs/?15373 ___ Nachricht geschickt von/durch Gna! http://gna.org/ ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev
