I am trying to use the attractor to influence movements of particle. It works fine when there are something to input into the attractor object for output; however when there is no input into the attractor then the attractor has no output. Is there a way to get around with this?
I was trying to edit the attractor.fx file from girlpower, but it seems to fail. is there a user manual for how to program effects?
The other option i thought about is to detect an empty spread before going into the attractor, and if there is an empty spread then I diverge off to do something else. however i am having some trouble detecting a null spread. How do i do this?
i am attaching my patch for reference.
