Script to run at creation of Prefab, not Start or Awake

Question

Topic says it all. Basically, I need to set some variables when the prefab is dragged and dropped onto the scene.

For example, I have a prefab of cars, and a script that changes the color of the car to a random color. I don't want all black cars in the editor, and then cars that are a different color each time I run the program. I want cars that are dropped on as black, instantly set to a color, and then that color remains the same at each time it's run.

I suppose I may be able to make an editor and use the editor to "paint" cars onto the scene, and have the editor script set the color.

But is it possible to have a script that's attached to the car that will set it's color when created?

What you a re looking for, it sounds like, is to have it execute while in the editor.

You do that with the ExecuteInEditMode attribute

This sounds like exactly what I need. I'll try it out, but I assume from reading the reference that it will do what I want.

This module http://unity3d.com/learn/tutorials/modules/intermediate/editor/adding-buttons-to-inspector

shows how to create a button to execute an action. Maybe you could add your object and then press the button to perform all kind of actions you are after.

This is also a good answer. It's not exactly what I wanted, but it's a good workaround, if Jeff $$anonymous$$. had not hit the mark. Sorry I can't vote you up.

$$anonymous$$eep in $$anonymous$$d that the ExecuteInEdit$$anonymous$$ode only works the first time. Then you won't get the changes. That may be what you want but it means if your car is black it won't change color anymore.
