/*QUAKED target_laser (0 .5 .8) (-8 -8 -8) (8 8 8) START_ON RED GREEN BLUE YELLOW ORANGE FAT WINDOWSTOP x x x x x SEEK_PLAYER
When triggered, fires a laser.  You can either set a target
or a direction.

WINDOWSTOP - stops at CONTENTS_WINDOW

"angle" aiming direction on the XY plane. Default=0. Ignored if target is used, and/or SEEK_PLAYER is set.
  
"angles" aiming direction in 3 dimensions, defined by pitch and yaw (roll is ignored). Default=0 0 0. Ignored if target is used, and/or SEEK_PLAYER is set.
  
"count" When non-zero, specifies the number of times the laser will be turned off before it is auto-killtargeted (see this page for details). Default=0.

"wait" If non-zero, specifies that the laser will pulse on and off automatically. The value specified here sets the amount of time (in seconds) between pulse cycles. Default=0. Also requires the use of delay. (Please see the notes below regarding timing issues when using pulse lasers).

"delay" amount of time, in seconds, that a laser pulse will be on. This value must be less than the value of wait. Default=0. Ignored if wait=0.
  
"dmg" the number of damage hit points the laser will do every 0.1 seconds. Default=100. If set to a negative value, the laser will give health, but will not cause pain effects. Ignored when style>0.
  
"mass" Sets the width of the laser. When 0, uses the default internal value of 4 for normal lasers, or 16 for fat lasers. When non-zero, FAT is ignored. Default=0.
 
"style" Sets the behavior of the laser. When non-zero, dmg is ignored. Choices are:
   0: Affects health, monsters avoid, creates sparks (normal, default laser).
   1: No damage; monsters avoid; creates sparks.
   2: No damage; monsters ignore; creates sparks.
   3: No damage; monsters ignore; no sparks.

"movewith" Targetname of parent entity the laser is to movewith.

"target" Targetname of the entity the laser will fire at. If SEEK_PLAYER is set, the player is a higher priority target, and therefore the entity specified by "target" will be ignored, assuming the laser has a clear shot at the player. In the event SEEK_PLAYER is set and the laser has no clear shot at him, it will fall back to firing at its "target".
  
"targetname" the specific target_laser.

/*QUAKED target_mal_laser (0 .5 .8) (-8 -8 -8) (8 8 8) START_ON RED GREEN BLUE YELLOW ORANGE FAT WINDOWSTOP
Mal's laser
Same as the normal laser entity but it flashes on and off.

WINDOWSTOP - stops at CONTENTS_WINDOW

"angle" aiming direction on the XY plane. Default=0. Ignored if target is used, and/or SEEK_PLAYER is set.
  
"angles" aiming direction in 3 dimensions, defined by pitch and yaw (roll is ignored). Default=0 0 0. Ignored if target is used, and/or SEEK_PLAYER is set.
  
"count" When non-zero, specifies the number of times the laser will be turned off before it is auto-killtargeted (see this page for details). Default=0.

"wait" If non-zero, specifies that the laser will pulse on and off automatically. The value specified here sets the amount of time (in seconds) between pulse cycles. Default=0. Also requires the use of delay. (Please see the notes below regarding timing issues when using pulse lasers).

"delay" amount of time, in seconds, that a laser pulse will be on. This value must be less than the value of wait. Default=0. Ignored if wait=0.
  
"dmg" the number of damage hit points the laser will do every 0.1 seconds. Default=100. If set to a negative value, the laser will give health, but will not cause pain effects. Ignored when style>0.
  
"mass" Sets the width of the laser. When 0, uses the default internal value of 4 for normal lasers, or 16 for fat lasers. When non-zero, FAT is ignored. Default=0.

"style" Sets the behavior of the laser. When non-zero, dmg is ignored. Choices are:
   0: Affects health, monsters avoid, creates sparks (normal, default laser).
   1: No damage; monsters avoid; creates sparks.
   2: No damage; monsters ignore; creates sparks.
   3: No damage; monsters ignore; no sparks.

"movewith" Targetname of parent entity the laser is to movewith.

"target" Targetname of the entity the laser will fire at. If SEEK_PLAYER is set, the player is a higher priority target, and therefore the entity specified by "target" will be ignored, assuming the laser has a clear shot at the player. In the event SEEK_PLAYER is set and the laser has no clear shot at him, it will fall back to firing at its "target".
  
"targetname" the specific target_laser.
