// Revision 1.12 2002/11/22 21:26:06 Flayra
|
|
// - Fixed turret factory abuse, where turrets became active after recycling the nearby turret factory before turret was fully contructed.
|
|
// - Fixed bug where siege turrets became re-activated after building a regular turret factory nearby.
|
|
// - mp_consistency changes
|
|
//
|
|
// Revision 1.11 2002/11/12 02:29:11 Flayra
|
|
// - Removed check for mp_testing with siege
|
|
//
|
|
// Revision 1.10 2002/11/03 04:52:18 Flayra
|
|
// - Removed server variables, hard-coded them
|
|
//
|
|
// Revision 1.9 2002/10/16 01:07:36 Flayra
|
|
// - Removed unused sounds
|
|
//
|
|
// Revision 1.8 2002/09/23 22:32:14 Flayra
|
|
// - Removed minimum range for siege
|
|
//
|
|
// Revision 1.7 2002/08/16 02:48:09 Flayra
|
|
// - New damage model
|
|

|
// - Linux case sensitivity stuff
|
|
//
|
|
// Revision 1.4 2002/07/23 17:27:47 Flayra
|
|
// - Siege no longer requires LOS (so it's actual siege)
|
|
//
|
|
// Revision 1.3 2002/07/01 21:47:27 Flayra
|
|
// - Added siege shockwave effect, added view shaking effects
|
|
//
|
|
// Revision 1.2 2002/05/28 18:07:19 Flayra
|
|
// - Reduced tracking rate for siege
|
|
//
|
|
// Revision 1.1 2002/05/23 02:33:20 Flayra
