 Description  « Hide
As of this very version of Windlight, number of particles pr. burst is severely weakened. I have been testing the exact same script in prior versions of Windlight as well as default viewer, and this behaviour is new.

Below is an example script you can test. In previous versions/default viewer, this script would create an instant cloud of particles produced by a single burst, when the object containing the script was clicked. In most recent Windlight it will produce 2-3 particles at best, sometimes none.

Example code for testing - stick in a prim and click:
//------------------------------------------------------------------------

startParticles()
{
llParticleSystem([
PSYS_PART_FLAGS, 0 |
PSYS_PART_INTERP_COLOR_MASK |
PSYS_PART_INTERP_SCALE_MASK |
PSYS_PART_WIND_MASK |

PSYS_SRC_MAX_AGE, 0.0,
PSYS_SRC_TEXTURE,"",
PSYS_PART_START_ALPHA, 0.6,
PSYS_PART_END_ALPHA, 0.0
]);
}

stopParticles()
{
llParticleSystem([]);
}

default
{
touch_start(integer total_number)

{ startParticles(); llSleep(0.5); stopParticles(); }

}
//------------------------------------------------------------------------

**Snapshot is another example comparing Release Candidate and Windlight with the same particle effect.
