Слежение 2д персонажа за курсором мыши

Я пытаюсь реализовать слежение 2Dперсонажа за курсором мыши, анимации переключаю с помощью паттерна State Machine в самом коде. Когда персонаж стоит, все работает исправно, но при движении возникает точка, в которой анимации меняются без перерыва. (Например, анимация вверх и влево(-0.7, 0.7))

Проблема возникает именно при движении персонажа, когда за ним следует камера.

У меня есть четыре направления анимаций:

• (1, 0) - вверх
• (-1, 0) - вниз
• (0, 1) - вправо
• (0, -1) - влево

Анимацию я меняю на ту, которая ближе к точке ((Vector2)Camera.main.ScreenToWorldPoint(Input.mousePosition) - _rigidbody.position).normalized

Движение персонажа происходит через _rigidbody.MovePosition()
