traer.physics age() does not return anything
Jun 24th, 2009, 5:28am  
Hi,

i have a odd problem, and wanted to see if anyone encountered it before...

i have 3 diffrent particle systems in my scetch, all worked fine, but i noticed, that the particles were not deleted anymore. i figured out, that when i call pX.age(), it always returns 0.0

i cant find any misstake, and when i reduce to only one Particle system, the correct age is given an counted normaly...

this is really odd, since i have to use diffrent systems. i tryed looking through the source, but im too dumb to figure it out -.-

any suggestions?

thx,
Troop

okay, i figured it out: the version with only one particesystem had as mode RUNGE_KUTTA, while i set the sketch with 3 diffrent systems to MODIFIED_EULER for preformance reasons.

turns out MODIFIED_EULER doesnt count the age ...

still odd but good to know.

when anyone knows a way to make MODIFIED_EULER count the age of the particles, lt me know, cause its much faster with as many particles as i use.
