* Revision 1.21 2007/07/19 03:19:32 turey
|
|
* Made Backslash's change to dampening tied to an ai_profiles flag, as it does affect
|
|
* retail behavior, and significantly affects gameplay in the BtRL Demo.
|
|
* Also, fixed a typo.
|
|
*
|
|
* Revision 1.20 2007/07/15 02:45:17 Goober5000
|
|
* fixed a small bug in the lab
|
|
* moved WMC's no damage scaling flag to ai_profiles and made it work correctly
|
|
* removed my old supercap damage scaling change
|
|
* moved Turey's truefire flag to ai_profiles
|
|
*
|
|
* Revision 1.19 2007/02/27 01:44:48 Goober5000
|
|
* add two features for WCS: specifyable shield/weapon recharge rates, and removal of linked fire penalty
|
|
*
|
|
* Revision 1.18 2006/12/28 00:59:18 wmcoolmon
|
|
* WMC codebase commit. See pre-commit build thread for details on changes.
|
|

|
|
* Revision 1.17 2006/09/11 06:49:38 taylor
|
|
* fixes for stuff_string() bounds checking
|
|
*
|
|
* Revision 1.16 2006/07/12 04:59:03 taylor
|
|
* fix the endless-loop fix ;) (this is what broke shield recharging btw)
|
|
*
|
|
* Revision 1.15 2006/07/06 18:19:59 Goober5000
|
|
* fix dumb endless loop bug
|
|
* --Goober5000
|
|
*
|
|
* Revision 1.14 2006/07/02 03:39:55 Goober5000
|
|
* remove associated AI flags
|
|
* --Goober5000
|
|
*
|
|
* Revision 1.13 2006/04/20 06:32:00 Goober5000
|
|
* proper capitalization according to Volition
|
|
*
|
|
* Revision 1.12 2006/03/20 06:25:19 taylor
|
|
* change wording to ease Goober's ulcer. ;)
|
|
*
|
|
* Revision 1.11 2006/03/20 06:19:03 taylor
|
|
* add ai_profiles flag to get rid of limit on minimum speed a docked ship can move
|
|
* (not going to Int3() here from < 0.1 speed by default, a support ship actually hit it)
|
|
*
|
|
* Revision 1.10 2006/02/13 04:56:58 Goober5000
|
|
* enabled modular tables for ai_profiles and added the default table to def_files
|
|
* --Goober5000
|
|
*
|
|
* Revision 1.9 2006/02/13 00:20:44 Goober5000
|
|
* more tweaks, plus clarification of checks for the existence of files
|
|
* --Goober5000
|
|
*
|
|
* Revision 1.8 2005/12/22 04:32:44 taylor
|
|
* GCC knows that fix == int so it hates the utility functions here, for sanity sake just rename them to type specific to avoid rampant casting
|
|
*
|
|
* Revision 1.7 2005/12/06 03:17:48 taylor
|
|
* cleanup some debug log messages:
|
|
* note that a nprintf() with "Warning" or "General" is basically the same thing as mprintf()
|
|
* make sure that OpenAL init failures always get to the debug log
|
|
*
|
|
* Revision 1.6 2005/11/24 09:08:44 Goober5000
|
|
* bah, forgot a colon
|
|
* --Goober5000
|
|
*
|
|
* Revision 1.5 2005/11/24 08:46:11 Goober5000
|
|
* * cleaned up mission_do_departure
|
|
* * fixed a hidden crash (array index being -1; would only
|
|
* be triggered for ships w/o subspace drives under certain conditions)
|
|
* * removed finding a new fighterbay target because it might screw up missions
|
|
* * improved clarity, code flow, and readability :)
|
|
* * added custom AI flag for disabling warpouts if navigation subsystem fails
|
|
* --Goober5000
|
|
*
|
|
* Revision 1.4 2005/11/24 07:27:14 taylor
|
|
* fix fred2 startup crash (we probably need to Assert() this case so it doesn't easily happen again)
|
|
*
|
|
* Revision 1.3 2005/11/21 15:01:18 taylor
|
|
* little cleaner, lot more friendly to 64-bit archs (long type is usually 64-bit there)
|
|
*
|
|
* Revision 1.2 2005/11/21 03:47:51 Goober5000
|
|
* bah and double bah
|
|
* --Goober5000
|
|
*
|
|
* Revision 1.1 2005/11/21 02:43:30 Goober5000
|
|
* change from "setting" to "profile"; this way makes more sense
|
