Slash/Sweep inside of a gameobject.

I am trying to achieve something like slashing and sweeping inside a circle sprite. I try something like edge collider2d attach to line renderer and the gameobject has a circle collider attached to it.
If i swipe from outside and will have trigger ontriggerenter2d and plus one to score.
However, I wanted to do something like I can swipe different direction continuously inside the sprite. For each different direction it will add one to score. Currently I can only do with ontriggerenter2d but it can only swipe once inside the circle.

Any advice I can achieve something like above?

 

Any help?????

 

Can you post a picture of your scene? That may help understand what you are trying to do.
