how to make a variable in a script that do not apply to all prefab istances

hi,
there is a way to make a public variable in a script that when setted doesn’t aplly to all prefabs?

for istance: I have a prefab with a script with field “name”, if I put a string inside and I do some modification to the prefab I don’t want this field to be applied to every prefab instance. There is a specifica marker to put in the script or is just not supposed to work in this way?

thanks

That is naturally how it works(all fields applied to any instance that has this component). To prevent the field from changing a Clone you can add a boolean called clone

public var clone:boolean; 

Then when you set the name of the object to the name field just add a conditional

function Start()
{
    if(!clone)gameObject.name=name;
}
function Clone() //when you instantiate the clone, set clone to true on that instance
{
    var instance=Instantiate(gameObject,Vector3.zero,Quaternion.identity);
    instance.GetComponent(MyScript).clone=true;
}
