Unity3D manages Component components.

Unity3D manages Component components.

We all know that Unity manages GameObject in a tree structure that is in the Hierarchy panel. But how does one manage components?

My colleague's test found this phenomenon:

Test: In U5, create a new Button.

Add a script to process the response of the clicked button:

Using UnityEngine; using UnityEngine. UI; using System. collections; public class TestComponent: MonoBehaviour {public void OnClick () {var text = FindObjectOfType (typeof (Text) as Text; Debug. log ("now:" + text. transform. parent. gameObject. name); Destroy (text );}}

Run the program and click View Log output.

Then we create a Button,

There is a question about this output. What is the output order of "Button2 --" Button1?

Adjust the Hierarchy panel order.

The results are the same, so. The management of these components by unity is more like Stack-Stack structure storage: [first, first, and foremost]

Every time a new GameObject is created, unity will automatically classify the components on the game object and place them in their respective stacks. Unity maintains a Stack for each component.
