Change value of Transform variable in Unity

问题

I have a camera which follows a car when a player is driving. The issue is the car : transform variable in the UnityScript looks like this

var car : Transform;

Which means I would have to drag the transform onto the little box in the side panel to assign it.

Is it possible to assign this variable within the code like:

var car : Transform = Player1;

//BTW Player1 is the transform I want

The reason why it needs to be changed is in the code I want it to change between Player1 Player2 Player3

dependant on the currently selected one (i already coded this part)

It depends on how and when you want to do it. From your Camera class you can do something like:

var car : Transform;

public void ChangePlayer(string playerName) {
  GameObject playerGO = GameObject.Find(playerName);

  if(playerGO != null)
    car = playerGO.transform;
}
