A SerializeField was defined in a script “EnemySpawner.cs” like this :
[SerializeField] EnemyMovement enemyPrefab;
EnemyMovement is a component but you were able to drag and drop an enemy prefab into it. What happens behind the scene to support this?
Hi Svet,
Welcome to our community! 
Unfortunately, most parts of Unity are not open-source, so we often do not know what is going on behind the scenes. That is also the case here.
