How to implement automatic ingame script rewriting

Hi,
Is it possible to have the script of a Gameobject’s component automatically rewritten during the game ? For example, a unit is at place A and its component’s script contains the path to go to place B. Once B is reached by the unit, the script is replaced by another script that contains the path to go to C.
Thanks.

You could remove the component that moves the game object from A to B when it reaches B and then Add the second script that moves the game object from B to c using

Destroy(scriptA) ;
gameobject.AddComponent(typeof(ScrpitBClassName));

However if you’re going to be recycling these id just enable one and disable the other.

Or better yet have instances of both classes that derive from a base class with virtual methods and switch bewteen the current instance like a simple state machine.
