Flash code (2)

30. Q: How can I optimize Flash animation to make files smaller and smoother?
A: Flash is a professional software developed by Macromedia for webpage production and animation creation. It is easy to operate and has functions.
Powerful and has become the de facto standard for interactive vector graphics and Web Animation.
However, if the size of the Flash Movie File is large and hundreds of KB, it will often keep online viewers
Waiting for patience. It is necessary to optimize Flash movies, but the premise is that we cannot damage the movies.
Playback quality.
1. Use multiple symbols ). If an element in a movie is used more than once, consider converting it.
Is the symbol. Repeated use of symbols does not significantly increase the size of a movie file, because the file only needs to store a symbolic graph once.
Data.
2. Use gradient animation whenever possible. Whenever possible, try to use "Create motion tween "(
), Instead of "frame by frame gradient" (-.
The more key frames are used, the larger the movie file.
3. Use solid lines instead of dotted lines. Limit the number of special line types, such as dashes, dotted lines, and wavy lines. By
The line diagram for solid lines is the simplest, so using solid lines will make the file smaller.
4. Use multiple vector images and less bitmap images. Vector images can be scaled at will without affecting the image quality of flash. Bitmap
Generally, an image is used only as a static element or background image. Flash is not good at processing bitmap images. Therefore, bitmap images should be avoided.
Element animation.
5. Use a simple vector image. The more complex a vector image is, the more effort the CPU can perform. Menus available
Command modify (modify)/curves (curve)/optimize (optimize) to delete unnecessary lines in a vector image
To reduce the file size.
6. The imported bitmap image file is as small as possible and compressed in JPEG mode.
7. It is best to compress audio files in MP3 mode. MP3 is a format that minimizes sound usage.
8. Limit the font and Font Style quantity. Try not to use too many different fonts. The more fonts, the more electricity
The larger the shadow file is. Use the font set in flash as much as possible.
9. do not include all font shapes. If the text field is included, consider (
In the text domain Attributes dialog box, select include only specified font outlines (excluding the specified font only ).
And do not select include all font outlines (including all font shapes ).
10. Try not to scatter the font (the menu command is modify/break apart ). After the font is dispersed, it becomes
This will increase the file size.
11. use as little as possible the transition fill color. Fill an area with a transition fill color than fill an area with a solid color
It takes about 50 bytes.
12. Try to narrow down the action area. Limit the area in which the key frame changes.
It may be in a small area.
13. Try to prevent multiple objects from generating actions at the same time. Do not associate objects with other objects with actions.
Static objects are arranged in the same layer. Action objects should be arranged in their respective dedicated layers to accelerate fl
The processing process of the ash animation.
14. Run the load movie command to relieve the burden on starting a Movie Download. If necessary, consider dividing movies
Into multiple sub-movies, and then use the load movie and unload movie commands in the main movie to call and uninstall sub-movies at any time.
Movie.
15. Use the pre-Download screen. If necessary, you can add a predownload image (preloader) at the beginning of the movie)
So that the video can be played smoothly. Large audio files must be pre-downloaded.
16. The smaller the length and width of a movie, the better. The smaller the size, the smaller the movie file. You can use the menu command modify
(Modify)/movie (movie) to adjust the length and width of the movie.
17. Make a small-sized movie and then enlarge it. To reduce files, you can consider
The size is smaller, and then the mini SWF movie is exported. Next, set the menu file/publish settings...
(Release settings ...) In the HTML tab, the film size is larger, so that the page will display the size
The quality of a large movie is intact and elegant.
When making the above changes, do not forget to test the playing quality, download status, and view movie files at any time.
Size.
31. Q: Why do I always follow a straight line when I use flash for "moving along the track"? I compared it with the tutorial. The practice is exactly the same. Why can't I?
A: This question seems to always plague beginners, but it is actually very simple. The center position of the first and second frames is not placed on the track. A simple check method: You can set the screen size to 4 00% or greater to check whether the circle in the middle of the graph is aligned with the motion track.
32 . Q: Why is it always unpleasant to rotate in flash. Is there any way to make it faster?

33 . Q: What is "hit" used to create a button? When will it be used? I have not explained the usage of "hit" in many tutorials.
A: Hit specifies the exciting area of the button. The areas set in hit are not displayed during playback. If the hit area is not specified, flash usually uses your new area as the excitation area by default. For example, when using text as a button, it is best to define a rectangle as the trigger area, rather than the default text content.
34 . Q: How can I put flash in fp2000 and fp98?
A: fp98 and fp2000 have poor support for flash. Flash Animation cannot be directly inserted in the flash file. The solution is to release the SWF file Code After the file is generated, copy the <; Object> part of the HTML file. It is recommended that you use dreamweave to create a flash animated webpage, which is much more convenient.
35 . Q: How to output a FLA file to a GIF file like SWF?
A: First, choose publish Settings> Format> GIF image and set it accordingly. Then, use publish (publish) function to output GIF files. If the FLA file contains MC, The GIF file will not contain the animation in MC, but will only convert the first segment of m c to GIF.
36 . Q: Why do I have to wait a long time for the flash to be displayed after I put a completed flash with only a dozen K flash into the webpage and preview the webpage.
A: Check whether the SWF file name and path are correct. If the path is incorrect, the system will try to wait for a long time.

A: Choose "Main Menu"> "Windows"> "Inspector"> "scene" to adjust the playing sequence, change the name, and delete the scenes.
44 . Q: How can I watch Flash Animation in Linux? Is there a plug-in for Linux?
A: http://www.openswf.org/yes.
46 . Q: How can I generate an EXE file directly from the FLA file?
A: An SWF file with a title bar can generate an EXE directly through the menu. in Flash Player, open the SWF file and select File> creat projector to create a project ). If the file title bar is not displayed in full screen with the FS command, you can use the CTRL + F hotkey to generate the file. The generated execution file has a built-in player, which is more than two hundred K larger than the SWF file.
47 . Q: How can I convert the flash to screen protection?Program?
A: Use SWF browser 2.8 or screensaver. Download http://iching.topcool.net.
48 . Q: How can I borrow content from others' works. Whether the SWF file can be fully decoded into a FLA file.
A: SwF browser 2.8 can be used to unbind other SWF files and extract and save the images and sounds. So far, no software can completely convert SWF files into FLA files.
49 . Q: How to Implement 3D effects in flash.
A: In flash, 3D animations cannot be generated. You need to use other software. For example, 3D max, and then install vecta3d or javasstrate! The 4.0 (4.1) Plug-in can directly output an animation in swf format.
50 . Q: Can the animation background of Flash be transparent? How to Set it?

120 . Q: How to Make Mc always follow the mouse Rotation

A: calculate the difference between the vertical and horizontal coordinates of MC and the mouse, and then use math. atan2 () to calculate the rotation angle.
M_x = _ root. _ xmouse-MC. _ x;
M_y = _ root. _ ymouse-MC. _ y;
MC. _ rotation = Pi = 180/Math. Pi * Math. atan2 (m_y, m_x );

121. Q: How to Achieve the mouse-following effect??
A: The basic code is as follows. Step A is the step size.
MC. _ x + = (_ root. _ xmouse-MC. _ x)/
MC. _ y + = (_ root. _ ymouse-MC. _ y)/

122.Q: Can I explain loadmovie in detail?
A: The question about loadmovie is the setting of attributes after loading ..
Loadmovienum (URL, level, method );
The URL is the relative or absolute URL of the SWF file you want to load. For example, "snow.swf" or "http://go8.163.com/6s
Now9/myflash/snow.swf ", we strongly recommend that you put all SWF files to be loaded under the same directory
Level specifies the level to which the loaded SWF is placed. The value range is 0 --- n.
