- Rez the particle station on the ground
- Play with the controls until you like the effect
- Touch ? for a menu, then ShowScript to get the script particle command. You will
get something like this:
PSYS_PART_END_GLOW, 0.00 ]);
How to test the script
- Create a new prim on the ground
- Look in its contents. Create a new script
- Edit the script, delete all of the text
- Paste in the script from the particle lab and save.
- Your new prim should be emitting the same particle stream as the lab
A hover tip is the little window the pops up under your mouse when you hover over an object.
It can be a real pain when trying to click buttons on in-world rezzed objects like the Particle
Lab, as well as anything else in-world. It is possible to turn hover tips OFF.
Preferences -> User Interface -> Uncheck "Show Hover Tips"
|Many of the appearance properties are controlled by a 3-panel control button.
- There is a center panel which can be clicked anywhere along its length. It gives less - or - more
of the effect depending on where you click it.
- The left hand button sets the property to a minimum value
- The right hand button sets the property to its maximum value
|Some of the 3 panel control buttons have 2 ranges.
- Note the horizontal line across the center panel.
- The top half of the button gives you full range control, min to max.
- The bottom half of the button gives you a finer degree of control in the lower portion of the range. This is useful for some
parameters where you may want a "little" of the effect and its hard to
select with the full range controller.

||Set the particle texture. Enter the UUID of the texture on a chat command line on channel 889900. The easiest way to get the UUID (key)
of a texture is to find it in inventory, right click it, and COPY ASSET UUID. Your command in open chat will look something like this:
||Shows the llParticleSystem script command that generates the current effects. You can paste this into your own
script in your own object.
||Resets the lab to the default particle effect.
||Toggles Verbose mode ON and OFF. When ON the Partcle Lab becomes "chatty" telling you the value of every
control adjustment as you make it.
||Directs you to a web page where you can retrieve saved settings. More details on particle libraries are here:
Particle Lab Libraries
This web page is not intended to be a tutorial on particle generation. Full instuctions on particle generation can
be found in the LSL wikki. Each of the buttons controls a parameter of the particle generator, a short description
of each functions follows here...
||Turn the particle generator ON and OFF
||How often to generate particles. Lower numbers generate particles more often. A value of zero makes the particle generate as often
as the viewer can show them.
||How long do particles stay on the screen. Bigger numbers = longer
||When particles are generated, how many are generated at once?
||How far away from the prim do the particles initially appear?
||How long should the generator make particles? Bigger numbers = longer. Max = 30 sec. A value of zero generates particles forever.
|Minimum and maximum "flight" speed of the particles
|Begin and end "transparency" of particles. Zero = invisible. Max = completelyt solid
|Controls the range of angles at which particles are generated. Works with ANGLE and ANGLECONE modes
|PUSH X, Y, Z
||Applies an amount of force to the particles in different directions. BiDirectional. The  buttons disable push.
|SPIN X, Y Z
||Applies an amount of spin to the particle patter in various axes. BiDirectional. The effects can be seen most easily with ANGLE or ANGLECONE.
choose a STARTANGLE and ENDANGLE that directs particles off in some direction (not full spherical 360) then apply some spin.
The  buttons disable spin.
|Controls the begin and end size of the particles. This is a 2 dimensional control. Clicking various places in the box selects different
height and width particle sizes.
The = button, when lit green, forces the begin and end size of particles to be the same.
The "square" button, when lit green, forces the width and height of the particles to be the same.
||Choose begin and ending color of the particles. Choose a color by clicking in the main panel of the control. Choose light/dark with the
thin verical bar on the left. Switch between START and END colors with the circular arrow button.
||Particles explod outward in all directions
||Particles fly out at controlled angles. BeginAngle and EndAngle control the range where particles are created.
||Similar to ANGLE, but particles are generated in a "flat cone"
||Creates particles with no initial velocity. PUSH is in effect.
||Particle are affected by wind
||Particles "bounce". They will not sink below the height of the emitter prim
||Particles are "fullbright" as if the sun were shining full on them. This negates the effect of point (ambient) lighting
||When set, particles are joined together into one continuous triangle strip
||When set, particles move relative to the position of the emitter. Otherwise, particle position and
movement are unaffected by the position/movement of the emitter.
|| When set, particles rotate to orient their "top" towards the direction of movement or emission.
Otherwise, particles are oriented vertically as their textures would appear (top of texture at top, left at left).
||Makes the emmitter prim move side to side so it is easier to see the effect of settings like FollowSource, FollowVel, Drop, etc
