Add Impulse to a specific Vector

Hi there, I have this thing I am building with an arrow that I am unsure how to get the direction of an object and use that to create an impulse in a specific direction.

I have a transform variable here that owns the current rotation of the arrow, I’d like to take that rotation and build the impulse.

My vector is being built from the relationship between two objects. Maybe I could use inverted vector values, I’ll try fiddling with that.

Yeah all good, that did it. I just take the vector relationship I’ve made and inverse the output.
