    Hi ,
    I want to highlight an area (in red color) that is NOT in the range of field of view due to some obstacle.
    I found tutorials that help to highlight the area inside the field of view but I need the inverse of that i.e Area that is not in the field of view should get highlighted.

    A small image is attached. In the provided image I need to highlight Red Area. Square is my obstacle, blue circle is my player and Yellow circle is the weapon range.

    This isn't a physics problem, it's more of a computational geometry problem. You can use libraries such as clipper to produce these kinds of outlines, calculate unions and perform geometry operations on them etc.

    There's certain no physics code that'll generate this for you unless you can narrow it down to an inherently physics related requirement.
