Help Add vector and script when hit collider.

[josemendez]

I could do that.

Can I attach script or component without colliding? For example, particles that are in (or enter) the box(or in the area) gain script or component.

Hi,

I think you want to use a trigger (built-in Unity stuff). Simply enable the "IsTrigger" checkbox of your collider. It will detect particles entering it, but won't generate collisions. See:
