/*QUAKED turret_breach (0 0 0) ? OCCUPIABLE TRIGGER_SPAWN TRACK
This portion of the turret can change both pitch and yaw.
The model should be made with a flat pitch.
It (and the associated base) need to be oriented towards 0.
Use "angle" to set the starting angle.
OCCUPIABLE - player can jump on this turret and use it
TRIGGER_SPAWN- Spawns upon being triggered
TRACK- It will attack the player without having a driver.
"speed" default 50
"dmg" default 10
"distance" initial velocity of fired grenades in units/sec
"angle" point this forward
"target" point this at an info_notnull at the muzzle tip
"minpitch" min acceptable pitch angle : default -30
"maxpitch" max acceptable pitch angle : default 30
"minyaw" min acceptable yaw angle : default 0
"maxyaw" max acceptable yaw angle : default 360
"target" the info_notnull (rocket origin)
"targetname" name of this breach
"team" give this the same value as the turret_base "team" key
"health" if set, it explodes like a func_explosive- default to 100 health, 75 mass, etc
It will not destroy the turret base.
"sounds" - weapon to use -
1) Railgun
2) Rocket Launcher
3) BFG
4) Homing Rockets
5) Machine Gun
6) Hyperblaster
7) Grenade
8) Blue Hyperblaster
9) Green Hyperblaster
"wait" The meaning of "wait" is dependent on the weapon type (sounds) used. Firing rate: When sounds=1, 2, 3, 4, or 7 (RG, RL, BFG, HomingRL, GL), "wait" sets the number of seconds to wait between weapon firing events. Note: An additional skill-level dependent "reaction time" delay is added to this, as described by the formula:
[reaction time]=[2-skill]/2
So if a RL turret uses wait=1, on normal skill the actual time between firings would be 1.5 seconds. Damage level: When sounds=5 or 6 (MG or HB), "wait" sets the amount of damage points each shot will do (firing rate is fixed at 10 shots/second). Ignored when sounds=-1. Default=2.
