1. Note that a total of three pictures, one is bottom slab (pic_old) placed at the lowest level, a new diagram is switched to (pic_new) placed in the middle layer, and finally a new picture of the Mask layer (mask);
2. The new diagram and bottom slab of the depth should not be reversed, the new picture is higher than the bottom slab depth, otherwise there will be errors;
3. We only make the article on the mask, let the mask to load the mask, so you can accomplish many different effects.
Step 1:
(1) Draw a square (50*50), register point in the center, save for movie clip Connection-> Export-> identifier REC;
(2) Draw a circle (50*50), the registration point in the center, save for the movie clip Connection-> Export-> symbol Cir;
(3) Import Pictures n Zhang, are saved as movie clips, registration point on the left (0,0) These pictures of the connection-> Export-> markers from Pic1, Pic2, pic3 ... picn
Step 2:
Add as code:
var old_p:string;
Temporary variable for storing the current picture
var n:number = 0;
Variable n is the current picture
var num:number = 5;
Num number of pictures
//=======================================================
Click after the mouse to set the bottom layout, new map and mask layer, and call (Passeffect)
_root.onmousedown = function () {
n = n < Num? ++n:1;
_root.createemptymovieclip ("Pic_old",-3);
Pic_old.attachmovie (Old_p, old_p, 1);
old_p = "pic" +N;
_root.createemptymovieclip ("Pic_new",-2);
Pic_new.attachmovie ("pic" +n, pic, 1);
_root.createemptymovieclip ("Mask",-1);
Pic_new[pic].setmask (mask);
When testing, you can comment out the setmask to better observe the mask layer
Passeffect ();

Flash charging 1 : Movieclip.setmask method Mc.setmask (mask:object): Makes movie clips in parameter mask the mask layer of the MC.
Flash charge 2: conditional operator (three-mesh operation)?: Format: expression1? Expression2:expression3
For example:
var x:number = 5;
var y:number = 10;
var z = (x < 6)? x:y;
Trace (z);
//returns 5
