[quote="Madster":2usmaaf4]If you want the trail particles to live longer than its "master", you could set a private variable in each of them with the UID of the "master", then when a "master" object dies you would look up their children comparing their private variable with the UID of the dying "master" object and set off a timer behavior to kill it later.
Doing so would kill the whole trail at the same time but a little while after the "master" dies.
Of course, you could also have the timer event set off timers for other children, in which case you can arrange some pretty complex dying orders just storing the proper UID in the proper particle.[/quote:2usmaaf4]
interesting , it is more realistic that way ... the way i did the particles dont disappear right away... i'll do that thnx
