// Revision 1.35  2002/05/23 04:58:05  blaze
// More sound changes as per Sze, please dont kill me Cent
//
// Revision 1.34  2002/05/22 04:20:37  blaze
// Sound entity changes as per Sze - teach me to comit when Sze is still talking
//
// Revision 1.33  2002/05/22 04:19:22  blaze
// Sound entity changes as per Sze - more
//
// Revision 1.32  2002/05/22 04:17:18  blaze
// Sound entity changes as per Sze
//
// Revision 1.31  2002/05/16 06:57:54  makro
// Doors with health (again !), bot-only trigger_pushes

// Revision 1.30  2002/05/15 12:46:32  makro
// Small func_static change.Give ammo should now give grenades/knives
//
// Revision 1.29  2002/05/13 04:41:26  makro
// Bug with doors (mine !)
//
// Revision 1.28  2002/05/11 12:45:25  makro
// Spectators can go through breakables and doors with
// a targetname or health. Bots should crouch more/jump less
// often when attacking at long range
//
// Revision 1.27  2002/05/11 00:38:47  blaze
// trigger_push and target_push default to no noise when the noise flag is not set.
//
// Revision 1.26  2002/05/05 15:18:02  makro
// Fixed some crash bugs. Bot stuff. Triggerable func_statics.
// Made flags only spawn in CTF mode

/*QUAKED func_door (0 .5 .8) ? START_OPEN CRUSHER AUTO_OPEN TOGGLE
Normal sliding door entity. By default, the door will activate when player walks close to it or when damage is inflicted to it.
-------- KEYS --------
angle : determines the opening direction of door (up = -1, down = -2).
speed : determines how fast the door moves (default 100).
wait : number of seconds before door returns (default 2, -1 = return immediately)
lip : lip remaining at end of move (default 8)
targetname : if set, a func_button or trigger is required to activate the door.
health : if set to a non-zero value, the door must be damaged by "health" amount of points to activate (default 0).
dmg : damage to inflict on player when he blocks operation of door (default 4). Door will reverse direction when blocked unless CRUSHER spawnflag is set.
team: assign the same team name to multiple doors that should operate together (see Notes).
light : constantLight radius of .md3 model included with entity. Has no effect on the entity's brushes (default 0).
color : constantLight color of .md3 model included with entity. Has no effect on the entity's brushes (default 1 1 1).
model2 : path/name of model to include (eg: models/mapobjects/pipe/pipe02.md3).
origin : alternate method of setting XYZ origin of .md3 model included with entity (See Notes).
notfree : when set to 1, entity will not spawn in "Free for all" and "Tournament" modes.
notteam : when set to 1, entity will not spawn in "Teamplay" and "CTF" modes.
notsingle : when set to 1, entity will not spawn in Single Player mode (bot play mode).
soundstart : path to sound file to play when door starts to open
soundstop : path to sound file to play when door comes to a stop
soundmove : path to sound file to play when door is moving
-------- SPAWNFLAGS --------
START_OPEN : the door will spawn in the open state and operate in reverse.
CRUSHER : door will not reverse direction when blocked and will keep damaging player until he dies or gets out of the way.
TOGGLE : door requires an opendoor toggle to open or close
AUTOOPEN : door will open like traditional Q3 doors (like a motion sensor)
-------- NOTES --------
Unlike in Quake 2, doors that touch are NOT automatically teamed. If you want doors to operate together, you have to team them manually by assigning the same team name to all of them. Setting the origin key is simply an alternate method to using an origin brush. When using the model2 key, the origin point of the model will correspond to the origin point defined by either the origin brush or the origin coordinate value.*/

/*QUAKED func_door_rotating (0 .5 .8) START_OPEN CRUSHER AUTO_OPEN TOGGLE X_AXIS Y_AXIS
This is the rotating door... just as the name suggests it's a door that rotates
START_OPEN	the door to moves to its destination when spawned, and operate in reverse.
REVERSE		if you want the door to open in the other direction, use this switch.
TOGGLE		wait in both the start and end states for a trigger event.
X_AXIS		open on the X-axis instead of the Z-axis
Y_AXIS		open on the Y-axis instead of the Z-axis

You need to have an origin brush as part of this entity.  The center of that brush will be
the point around which it is rotated. It will rotate around the Z axis by default.  You can
check either the X_AXIS or Y_AXIS box to change that.
