Создание управление по типу игры Ballz

Вот вам основная часть скрипта. Остальное допишите сам. Не трогайте скрипт, если не разбирайтесь в высшем математике!

Внимание: Этот скрипт вы должны ставить на мяча.

public class Control : MonoBehaviour
{
    public float force;
    float distance, rotation, rotationRadian;
    bool canGo;
    public GameObject Ball, LeftWall, TopWall, RightWall;

    }

        Drop();
    }

                Ball.transform.position.y + force * Mathf.Cos(rotationRadian)
            );
        }
