Start Order between GameObjects ？ Start Order between several scripts within a GameObject?

Hi , I'm curious about the Start order between several scripts within a GameObject and the Start order between GameObjects. So I did a little experiment,and then I found：

Unity may be use STACK to manage Scripts and GameObjects. In a GameObject ,the LAST script added to GameObject will be exectue FIRST. So do GameObject.

Did I get it wrong？

 

The order in which Start, Update and all the other methods are called in is undocumented, and pretty arbitrary. The general tip is to never, ever base your code around the order in which start is called. I mean, yes it might be that the order added is the order used, but you're never guaranteed that it'll be the same order in the next version.

Rather, use Awake and Start when things have to happen in order, or if you need a larger, ordered system, use a controller object that initializes the other ones.

 

Here is what documentation exists on the order.
http://docs.unity3d.com/Manual/ExecutionOrder.html

The order between GameObjects is undocumented, as Baste said.


If you really really need to have control over the order. There is the script execution order settings, where you can define some script by class type that has some priority order.
