Враги заходят в друг друга unity 2D

Когда я начинаю убегать от врагов(у меня отвечает отдельный скрипт за их спавн), они как-бы сливаются друг с другом и в итоге все находятся в одном враге(то есть может показаться что там не 5 врагов, а 1). Возможно это связанно с transform, но я не знаю.

Код:

    }
