Hi.
I have a script to send an event on trigger / collision maybe you can use it.
but you can only get the collision of a particle group not from a single particle from that group.
i don't know if that is possible tho.
Place the script on the object with triggers or collider enabled
then drag in the target fsm into the 'Particle fsm'
and place the event names to send.
You can also set a tag to compare to.
