dop2000 Thanks man.
I tested it and it works.
I have another question. Is it possible to optimize it ?
Using "for each" is CPU intensive, and I have a lot of other effect creators in my main project.
So, is there another way to optimize this or I should use an event like, every 0.1 seconds ---> check this ?
Using every 0.1 seconds reduces the cpu usage from 1.3/1.5 to 0.5/0.7 .
