Simply example:
Code:
new Float:org[3],Float:org1[3]
pev(player,pev_origin,org)
fm_get_aim_origin(player,org1)
new beams = Beam_Create(REFLUX_BEAM,10.0)
Beam_Init(beams,REFLUX_BEAM,10.0)
Beam_PointsInit(beams,org,org1)
Beam_SetColor(beams,{255.0,255.0,255.0})
Beam_SetNoise(beams,50)
creating beam from use origin to user aim origin
