How can one detect if a script being added?

Questions & Answers

Let’s say I want to create a script that would automatically find a reference to some (irrelevant) object. However, I would like the script to do that only once - when it was added on the object (via an editor).

Is there any method that I’m missing that is run in that script when it is first added on a game object?

I have tried using Validate method, but it is run every time you change any property of the script. I could make a flag for that, but that would not be super-clean. Alternatively, I could make the same flag for Awake and go for ExecuteInEditMode, but there are other complications related to that.

if(gameObject.GetComponent() != null)
{
//Script is attached
}
else
{
//Script is not attached
}

Not sure if this will work just came up with as it as it made sense to me, might have to remove the parenthesis
