//============================= About Parameters =============================
// There are 22-ish NAMED attributes that affect a particle display.
// To customize a display you give each a VALUE.
// For example: PSYS_PART_START_COLOR is a named attribute,
// and <1.0, 0.5, 0.0> is a color VALUE (orange, in this case).
//
// As long as your 'names' and 'values' are paired up properly, they can
// be in any order!  Any you omit a pair, it reverts to a default value.
 
//============================= Texture Parameters =============================
//
// TEXTURE, can be an "Asset UUID" key copied from a texture
//          that you have full permissions to, or the name of
//          a texture in the prim's inventory.
//
// SCALE, (size) 0.0 to 4.0 meters wide, by 0.0 to 4.0 meters tall. (default 1x1)
//          Textures are FLAT, so the 'z' part of the vector is ignored.
//          Values smaller than 0.04x0.04 may not get rendered at all.
//          Tiny particles vanish if the viewer is not near them.
//
// BEGIN_SCALE sets particle start size.
// END_SCALE (end size) is ignored, if the INTERP_SCALE_MASK option is disabled.
//
// COLOR, < RED, GREEN, BLUE > from <0.00,0.00,0.00> (black) to <1.00,1.00,1.00> (white/default)
// ALPHA, 1.0 = 100% visible(default), 0.0 = invisible.  Less than 0.1 might not get seen.
// START_COLOR and START_ALPHA set the color and transparency of newly created particles.
// END_COLOR and END_ALPHA are ignored, if the INTERP_COLOR_MASK option is disabled.
 
//============================= Production Parameters =============================
//
// BURST_PART_COUNT: quantity of particles per burst, 1 to 4096 (default 1),
//
// BURST_RATE: seconds to delay between particle bursts. 0.0 to 30.0 (default 0.1)
//
// PART_MAX_AGE: particle lifespan in seconds, 0.00 to 30.0 (default=10.0)

//
// SRC_MAX_AGE: emitter auto shut-off timer. 1.0 to 60.0 seconds. 0.0 = never stop. (default)
 
//============================= Placement Parameters =============================
//
// PATTERN:
//      DROP, ignores all other placement settings.
//      EXPLODE, spray particles in all directions
//      ANGLE, sprays a flat "fan" shape defined by ANGLE_BEGIN and END values
//      CONE, sprays "ring" or "cone" shapes defined by ANGLE_BEGIN and END values
//
// RADIUS:  0.0 to 50.0?  distance from emitter to create new particles
//      (RADIUS is disabled with DROP pattern and the FOLLOW_SRC & TARGET_LINEAR options)
//
// SPEED: 0.00 to 50.0?  Sets min/max starting velocities for non-drop patterns. (default: 1.0)
//
// ANGLE_BEGIN & END:  0.00*PI (up) to 1.00*PI (down),  (Only for ANGLE & CONE patterns)
//       (Values work much like the Sphere-prim's DIMPLE attributes.) (defaults: 0.0)
//
// OMEGA: <x,y,z> Sets how much to rotate angle/cone spray direction after
//                every burst. 0.0 to PI?  (default: <0,0,0>)
 
//======================== After-Effects & Influence Parameters ================
//
// ACCEL, x,y,z 0.0 to 50.0?  sets a constant force, (affects all patterns)
//          Causes particles to drift up/down or in a compass direction.
//          Use ACCEL to create the illusion of (anti-)gravity or a directional wind.
//          (ineffective with TARGET_LINEAR option)
//
// TARGET_KEY,  "key", (requires the TARGET option be enabled).
//       "key" can be a variety of many different things:
         // llGetOwner()
         // llGetKey() target self
         // llGetLinkKey(1) target parent prim
         // llGetLinkKey(llGetLinkNum() + 1) target next prim in link set
         //
         // WARNING: New copies of objects get new keys, you can't simply paste
         // a prim's key into your script and expect it to always work.  Visit
         // the Particle Laboratory's section on TARGETS for a variety of ways
         // to dynamically find your target's key. There are different 'best ways'
         // depending on if your target is linked to your emitter or not.
 
//============================= About Options =============================
//
// Each option may be ON/ENABLED (no leading // )
// or OFF/DISABLED (by putting a // in front of it.)
// Options are combined together in a special way, (using the | symbol).
// This creates one single Parameter for PSYS_PART_FLAGS.
 
//============================= Texture Options =============================
//
// EMISSIVE: identical to "full bright" setting on prims
//
// FOLLOW_VELOCITY: particle texture 'tilts' towards the direction it's moving
//
// INTERP_COLOR: causes particle COLOR and ALPHA(transparency) to change over it's lifespan
//
// INTERP_SCALE: causes particle SCALE(size) to change over it's lifespan
 
//======================== After-Effects & Influences Options ================
//
// BOUNCE:  particles bounce up from the z-altitude of emitter, and cannot fall below it.
//
// WIND: the sim's wind will push particles around
//
// FOLLOW_SRC: makes particles move (but not rotate) if their emitter moves, (disables RADIUS)
//
// TARGET_POS: causes particles to arrive at a some target at end of of their lifespan.
//
// TARGET_LINEAR: forces particles to form into an even line from emitter to target
//                and forces a DROP-like pattern and disables effects of WIND and ACCEL

//======================== USING CONTROL TEMPLATES =======================
//
// Want to control when your particles turn ON and OFF?   You can!
//
// Drop one (or more) of the CONTROL TEMPLATES from the particle laboratory
// into your object containing this script.  That's it!
 
// Your controls should be effective immediately.  (Some controllers can be
// adjusted and tuned, open them and read the USAGE notes to see.)
//
// One control template can control several particle templates in the
// same object.   (keep in mind that each prim can only have ONE
// particle effect active at a time).
//
// The 'particle_effect_name' value must be the same in both the control

// emitters try to create more than that, many will not be seen, and it may cause
// viewer lag.  Use as few particles as you can for your effect:
// AGE/RATE * COUNT will tell you approximately how many particles your emitter creates.
//
// SRC_MAX_AGE: emitter auto shut-off timer. 1.0 to 60.0 seconds. 0.0 = never stop. (default)
 
//============================= Placement Parameters =============================
//
// PATTERN:
//      DROP, ignores all other placement settings.
//      EXPLODE, spray particles in all directions
//      ANGLE, sprays a flat "fan" shape defined by ANGLE_BEGIN and END values
//      CONE, sprays "ring" or "cone" shapes defined by ANGLE_BEGIN and END values
//
// RADIUS:  0.0 to 50.0?  distance from emitter to create new particles
//      (RADIUS is disabled with DROP pattern and the FOLLOW_SRC & TARGET_LINEAR options)
//
// SPEED: 0.00 to 50.0?  Sets min/max starting velocities for non-drop patterns. (default: 1.0)
//
// ANGLE_BEGIN & END:  0.00*PI (up) to 1.00*PI (down),  (Only for ANGLE & CONE patterns)
//       (Values work much like the Sphere-prim's DIMPLE attributes.) (defaults: 0.0)
//
// OMEGA: <x,y,z> Sets how much to rotate angle/cone spray direction after
//                every burst. 0.0 to PI?  (default: <0,0,0>)
 
//======================== After-Effects & Influence Parameters ================
//
// ACCEL, x,y,z 0.0 to 50.0?  sets a constant force, (affects all patterns)
//          Causes particles to drift up/down or in a compass direction.
//          Use ACCEL to create the illusion of (anti-)gravity or a directional wind.
//          (ineffective with TARGET_LINEAR option)
//
// TARGET_KEY,  "key", (requires the TARGET option be enabled).
//       "key" can be a variety of many different things:
         // llGetOwner()
         // llGetKey() target self
         // llGetLinkKey(1) target parent prim
         // llGetLinkKey(llGetLinkNum() + 1) target next prim in link set
         //
         // WARNING: New copies of objects get new keys, you can't simply paste
         // a prim's key into your script and expect it to always work.  Visit
         // the Particle Laboratory's section on TARGETS for a variety of ways
         // to dynamically find your target's key. There are different 'best ways'
         // depending on if your target is linked to your emitter or not.
 
//============================= About Options =============================
//
// Each option may be ON/ENABLED (no leading // )
// or OFF/DISABLED (by putting a // in front of it.)
// Options are combined together in a special way, (using the | symbol).
// This creates one single Parameter for PSYS_PART_FLAGS.
 
//============================= Texture Options =============================
//
// EMISSIVE: identical to "full bright" setting on prims
//
// FOLLOW_VELOCITY: particle texture 'tilts' towards the direction it's moving
//
// INTERP_COLOR: causes particle COLOR and ALPHA(transparency) to change over it's lifespan
//
// INTERP_SCALE: causes particle SCALE(size) to change over it's lifespan
 
//======================== After-Effects & Influences Options ================
//
// BOUNCE:  particles bounce up from the z-altitude of emitter, and cannot fall below it.
//
// WIND: the sim's wind will push particles around
//
// FOLLOW_SRC: makes particles move (but not rotate) if their emitter moves, (disables RADIUS)
//
// TARGET_POS: causes particles to arrive at a some target at end of of their lifespan.
//
// TARGET_LINEAR: forces particles to form into an even line from emitter to target
//                and forces a DROP-like pattern and disables effects of WIND and ACCEL
 
//========================================================================
//======================== USING CONTROL TEMPLATES =======================
//
// Want to control when your particles turn ON and OFF?   You can!
//
// Drop one (or more) of the CONTROL TEMPLATES from the particle laboratory
// into your object containing this script.  That's it!
 
// Your controls should be effective immediately.  (Some controllers can be
// adjusted and tuned, open them and read the USAGE notes to see.)
//
// One control template can control several particle templates in the
// same object.   (keep in mind that each prim can only have ONE
// particle effect active at a time).
//
// The 'particle_effect_name' value must be the same in both the control
// and particle template to work.  You can change that value and have
// a controller for one effect, and a different controller for a different
// effect in the same object.

//============================= About Parameters =============================
// There are 22-ish NAMED attributes that affect a particle display.
// To customize a display you give each a VALUE.
// For example: PSYS_PART_START_COLOR is a named attribute,
// and <1.0, 0.5, 0.0> is a color VALUE (orange, in this case).
//
// As long as your 'names' and 'values' are paired up properly, they can
// be in any order!  Any you omit a pair, it reverts to a default value.
 
//============================= Texture Parameters =============================
//
// TEXTURE, can be an "Asset UUID" key copied from a texture
//          that you have full permissions to, or the name of
//          a texture in the prim's inventory.
//
// SCALE, (size) 0.0 to 4.0 meters wide, by 0.0 to 4.0 meters tall. (default 1x1)
//          Textures are FLAT, so the 'z' part of the vector is ignored.
//          Values smaller than 0.04x0.04 may not get rendered at all.
//          Tiny particles vanish if the viewer is not near them.
//
// BEGIN_SCALE sets particle start size.
// END_SCALE (end size) is ignored, if the INTERP_SCALE_MASK option is disabled.
//
// COLOR, < RED, GREEN, BLUE > from <0.00,0.00,0.00> (black) to <1.00,1.00,1.00> (white/default)
// ALPHA, 1.0 = 100% visible(default), 0.0 = invisible.  Less than 0.1 might not get seen.
// START_COLOR and START_ALPHA set the color and transparency of newly created particles.
// END_COLOR and END_ALPHA are ignored, if the INTERP_COLOR_MASK option is disabled.
 
//============================= Production Parameters =============================
//
// BURST_PART_COUNT: quantity of particles per burst, 1 to 4096 (default 1),
//
// BURST_RATE: seconds to delay between particle bursts. 0.0 to 30.0 (default 0.1)
//
// PART_MAX_AGE: particle lifespan in seconds, 0.00 to 30.0 (default=10.0)
//               PART_MAX_AGE less than 0.5 might not be visible.
