I only want to know how will I check if a given coordinate lies on a polygon2d or not

Do you need an intersection with its segment line?

There’s a function for that in the GDScript Geometry class:

bool is_point_in_polygon ( Vector2 point, PoolVector2Array polygon )

Returns true if point is inside polygon or if it’s located exactly on polygon’s boundary, otherwise returns false.
