Using unity 3D I am creating a 2D pizza game and I am stuck at finding an algorithm to solve this problem which is **Detecting if the pizza is half and half** taking into consideration that the user can put the toppings in all rotations shown in the picture and lot more possible distributions.

I used `Physics2D.OverlapAreaAll`

to get position of ingredients on the pizza and I tried getting the **sumX** and **sumY** of coordinates of all **topping A** and **sumX** and **sumY** of all **topping B** and adding **A.sumX** + **B.sumX** and **A.sumY** + **B.sumY** and if the 2 totals are **between 0 and 1** then A and B are on opposite sides but the bad distribution of toppings in the second pic is also accepted by my algorithm. The toppings must be spread like in the 1st pic

I need some easier way to detect the correct distribution of ingredients maybe using collisions or something.

`if (sumX > -ErrLvl && sumX < ErrLvl && sumY > -ErrLvl && sumY < ErrLvl) { Debug.Log("APPROVED HALF-HALF PIZZA"); } else Debug.Log("BAD HALF-HALF PIZZA"); `
