LlMakeFire

Wiki description

Make fire like particles

Notes

Beginning in 1.14, the simulator will be using llParticleSystem to emulate legacy llMakeFire particles.

llMakeFire(integer particle_count,
           float particle_scale,
           float particle_speed,
           float particle_lifetime,
           float source_cone,
           string source_texture_id,
           vector local_offset);

fakeMakeFire(integer particle_count, float particle_scale, float particle_speed,
             float particle_lifetime, float source_cone, string source_texture_id,
             vector local_offset)
{
//    local_offset is ignored
    llParticleSystem([
        PSYS_PART_FLAGS,            PSYS_PART_INTERP_COLOR_MASK | PSYS_PART_INTERP_SCALE_MASK | PSYS_PART_EMISSIVE_MASK | PSYS_PART_WIND_MASK,
        PSYS_SRC_PATTERN,           PSYS_SRC_PATTERN_ANGLE_CONE,

        PSYS_SRC_ANGLE_BEGIN,       0.0,

        PSYS_SRC_BURST_RADIUS,      0.0,
        PSYS_SRC_BURST_SPEED_MIN,   particle_speed,
        PSYS_SRC_BURST_SPEED_MAX,   particle_speed,
        PSYS_SRC_MAX_AGE,           particle_lifetime / 2,
        PSYS_SRC_OMEGA,             <0.0, 0.0, 0.0>
        ]);
}
//    Known discrepancies:
//    1) The original llMakeFire has random particle lifetime, which cannot be
//       created in the current particle system via a single call
//    2) The original llMakeFire has continual particle growth throughout its
//       lifetime, ending well past the 4m limit of the current system, on long lived
//       particles
//    3) several values are not taken 'verbatim' in the original particle system
//       (velocity is not m/sec for instance, and number of particles seems to be
//       wildly off), these are approximated loosely in this simulation via basic
//       divisors, which may not work out the same in some scenarios
//    4) There is no way to duplicate the offset from the old functions within the
//       new particle system
//    5) These effects do not 'pump' like the older functions do,
//       i.e. its a single, set property, calling it 10 times won't cause
//       10x as many particles, as the old ones did

Shared wiki helpers

The original page also injects shared parameter notes, caveats or issue information through these helpers. Their conditional MediaWiki logic is not reproduced here; inspect the preserved helper source for additional material.
