Particle pointer

I would like to make a pointer that will stream particles at the mouseview point. I know how to make the particle stream, I just can't figure out what to use for a target since it is not actually a target but a point in space in front of me.

This is doable to a certain degree. you need to create a follower "Bot" that gets your camera position and rotation and shoots a stream of particles straight forward. make the bot an invisiprim and it will appear like your camera is constantly transmitting a set of particles forward.

alternatively if you just want this to work in mouselook you can have an invisible attachment at waist height streaming particles forward and adjusting rotation according to the avatar's rotation.

Thanks for responding. Here is the particle system params I use to create the 'laser' beam:
[PSYS_PART_FLAGS,0 | PSYS_PART_FOLLOW_SRC_MASK | PSYS_PART_FOLLOW_VELOCITY_MASK | PSYS_PART_TARGET_LINEAR_MASK | PSYS_PART_INTERP_COLOR_MASK | PSYS_PART_INTERP_SCALE_MASK | PSYS_PART_TARGET_POS_MASK,
PSYS_SRC_PATTERN, PSYS_SRC_PATTERN_DROP,
PSYS_PART_START_ALPHA, 1.0,
PSYS_PART_START_COLOR, <1.0, 0.0, 0.0>,
PSYS_PART_END_ALPHA, 1.0,
PSYS_PART_END_COLOR, <0.0, 1.0, 0.0>,
PSYS_PART_START_SCALE, <0.05, 0.25, 0>,
PSYS_PART_END_SCALE, <0.05, 0.25, 0>,
PSYS_SRC_ACCEL, <0, 0, 0>,
PSYS_SRC_OMEGA, <0, 0, 0>,
PSYS_PART_MAX_AGE, 1.0,
PSYS_SRC_MAX_AGE, 0.0,
PSYS_SRC_ANGLE_BEGIN, 0.0,
PSYS_SRC_ANGLE_END, 360.0,
PSYS_SRC_BURST_PART_COUNT, 1,
PSYS_SRC_BURST_RADIUS, 0.0,
PSYS_SRC_BURST_RATE, 0.05,
PSYS_SRC_BURST_SPEED_MIN, 0.0,
PSYS_SRC_BURST_SPEED_MAX, 0.0,
PSYS_SRC_TARGET_KEY, llGetOwner(),
PSYS_SRC_TEXTURE, "34f2d0b0-6afd-c141-9562-b2d12d24ae4b" ]

(I picked this up off the forum here). My problem is that I don't know what to use for a target in order to get the particle beam to shoot straight forward. I have a working camera follower bot so I just need to get this particle stream to go. I am real new to particle doings in case you couldn't tell.

Thanks
