set variable when active

I have a model that is set to be active with SetActiveRecursively(true); in the first script. As soon as this model is active I want a different script to set a variable “three” to 0. After that the variable has to be able to be changed by other parts of the script (if I put it in the update function it makes the variable always equal to 0). That way I can make it equal to 1 in another part of the script. Is there any way to do this?

The object with the first script is the camera and the second script is on the model(child object of camera). Thank you for helping me, this worked very well! I put this in the second script to reset the variable three to 0 when the object is active. Thanks for the help!

Your question is a bit confusing…mostly because of “I want a different script to set a variable ‘three’ to 0.” Does it need to be a different script? If it can be done in the same script you can use MonoBehaviour.OnEnable.

function OnEnable () {
       three = 0;
       Debug.Log("This script was just enabled");
    }
