How Would You Create A Force Field Cone of Light That Is Projected From Character (Side Scroller)?

I am just unsure of the logic or setup to place a FORCE FIELD from the MyCharacter.

I have a 2d side scroller and already can aim the mouse any where on screen and shoot projectiles, etc. So this part works, but I am curious on the logic/setup need to have MyCharacter project a “Forcefield-like Cone” of light which would look like an umbrella to block rocks from falling on him?

Note: I have 360 aiming for the side scroller, shooting, and all that, I am just unsure of the logic or setup to place a FORCE FIELD from the MyCharacter and project it forward? Do I use a sphere, custom 3d model, etc?

Just curious how you would do this… thank you.

It seems I can use Cone (Volume) and use this like a shield to aim around my character.
