Pure as preloader created using [frame ()] data labels

 

The principle is to use the [frame ()] label to change the orientation of the document class. For specific operations, you can check on the Internet. There is a lot of information in this regard. I will only post the source code here and share it with you.

Code

 1 default program entry:
2
3 Package
4 {
5 import flash. display. Sprite;
6 Import MX. Core. bitmapasset;
7
8 [frame (factoryclass = "systemmanager", label = "hello")]
9
10 public class myapplication extends sprite {
11
12 [embed (Source = "test.png")]
13 private var bigpiccls: class;
14
15 public function myapplication (){
16 var B: bitmapasset = new bigpiccls () as bitmapasset;
17 addchild (B );
18}
19}
20}
21
22

 

Code

 1. Main Document class pointed:

51 var app: Application = new application ();
52. all resources in the application will be compiled to the first frame.
53. In this case, preloader will be meaningless, and you will not be able to see preloader, so you will jump to the second frame.
