/*SINED func_beam (0 .8 .5) (-8 -8 -8) (8 8 8) START_ON ANIMATE FAST ROLL RANDSTART ELECTRIC RANDALPHA
This creates a beam effect from the origin to the target's origin. If no
target is specified, uses angles and projects beam out from there.
"model" Specifies the model to use as the beam
"overlap" Specifies the amount of overlap each beam link should have. Use this to fill
in the cracks when using electric on beams. (Default is 0)
"minoffset" Amount of electrical variation at the endpoints of beam (Default is 5)
"maxoffset" Amount of electrical variation in the middle of beam (Default is 25)
"color" Vector specifiying the red,green, and blue components. (Default is "1 1 1")
"alpha" Alpha of the beam (Default is 1.0)
"damage" Amount of damage the beam inflicts if beam hits someone (Default is 0)
"angles" Sets the angle of the beam if no target is specified.
"life" Deactivates the beam life seconds after the beam is activated. If not set, beam
will not be deactivated.
"beamstyle" Sets the style for this beam to cycle through. This applies only
to beams without models. sample styles (121 blood, 120 gunsmoke, 123 orangeglow, 124 blueyellow,
125 debris trail, 128 oil, 129 waterspray 130 blue-yellow-blue) See global0.scr for
more style numbers
START_ON - Starts the beam on
ANIMATE - Plays animation of the model
FAST - Plays the animation at 20 frames/sec
ROLL - Rolls the beam
RANDSTART - Starts each segment of the beam's animation on a different frame
ELECTRIC - Applies a random electric efffect to the beam
RANDALPHA - Randomly generate the alpha for the beam
If the model field is not set, then a straight beam will be created using the color
specified. color, minoffset, maxoffset ,ANIMATE, FAST, ROLL, RANDSTART,
ELECTRIC, and RANDALPHA are not applicable if the model is not set.
