Single Image role action processing

Read the article on the internet about this: Use the BitmapData class, to cut the picture. Personally feel less trouble. Also, sometimes we might put the game's vegetarian village into a vector. To reduce the volume of flash.
Here's a personal view.
Fortunately Flash8 gives us: the Movieclip.cacheasbitmap attribute, the vector map is cached as a bitmap. I can check the help:
Mentioned: It is a good idea to use the Cacheasbitmap property with movie clips that are primarily static content and that are not scaled and rotated frequently. For such a movie clip, Cacheasbitmap can improve performance when you convert a movie clip (changing its x and Y positions).
In this way we make a single action, just put all the action in vector form, into a MC, with rows and columns.
To use a program to control: put a movie symbol on it to mask, displaying the animation of the current one.
The material for this example is a bitmap.
/* Operating principle
Create a new empty movie symbol: "Mc_tablemovie" as the container for the animation, animate the picture and import it into the library. plus the connection symbol. I set this up as "1."
Then set a Tablemovie animation object to Mc_tablemovie, and the object automatically generates two mcimg in "Mc_tablemovie": An animated picture, Mcmask: A movie symbol for masking.
In _root.onenterframe, to do the loop play

_root.createemptymovieclip ("Mc_tablemovie", _root.getnexthighestdepth ());
mc_tablemovie._x = 28;
Mc_tablemovie._y = 20;
Mc_tablemovie.attachmovie ("1", "Mcimg", mc.getnexthighestdepth ());
