Advantages and disadvantages of making courseware with flash

Flash is the predecessor of the Future Splash company launched a vector animation plug-in, Macromedia Company acquired Future Splash later to change it to a stand-alone flash software, to the current flash50, It can be said that Flash has become the standard of interactive vector technology, a major mainstream of future web production. In the practice of making courseware with flash, I feel that using flash to make courseware mainly has the following advantages:

　　"Stature" slender

Flash is the popular vector technology, with its creation of works, not only interactive function is powerful, colorful animation effect, stepless amplification of the vector map will never produce nasty sawtooth, and "stature" slim, file small, general courseware a 144 trillion floppy disk can be easily handcuffed. If you can skillfully use the action in the Loadmovie, Fscommand and other commands, then more than 144 trillion courseware can be more easily "carry" in batches. This is not full of hardware configuration (mainly without burner), the high rate of use of courseware schools and teachers, is undoubtedly an important advantage.

　　Illustrated

Flash itself has an extremely smart graphical rendering function, and more importantly, it can import not only common format images (such as images with file extensions of. jpg,.gif,.bmp), but also professional-level drawing tools such as Macromedia Freehand, Adobe Illustrator, etc.) draw the graph, and can make it flip, stretch, erase, skew and other effects, can also use lasso tools or magic wand in the image to select the same color area and create a mask (Mask); split the image into a number of single elements for editing, setting the properties of the graphic (for example, Produces smooth effect and quality lossless compression, etc.). Flash can handle custom fonts and its settings for color, size, spacing, spacing, indentation, and so on. In the use of Flash courseware, you can add a variety of titles and dynamic text, their data volume is very small. You can also convert a special font to a graphic, which avoids the embarrassment that the font cannot be displayed when the output of the artwork is not available because of a client font shortage.

"Dance" Beautiful

It is very easy to use flash to show movement and shape gradients of objects, and their processes are automatically generated without the need to manually insert keyframes between two objects. Use masks and paths to produce an excellent animation effect. If you have a strong painting skills, you can also draw frame animation, so that Creative unlimited play. Flash uses sprite animation, you can create dynamic buttons, multilevel pop-up menus, check boxes, and complex interactive crossword puzzles at your own discretion. If you are familiar with Vb,java script, then the essence of Flash action function will take you into a Xanadu.

　　Sound processing flexibility

Flash supports simultaneous WAV and AIFF-formatted sound files and sound connections, flash50 also supports MP3-formatted sound file connections, and you can use the sound editing features in Flash to make a rich sound effect on a portion of the same main channel without changing the size of the file. You can also set different voices in different layers to easily achieve the mix, which other software can not easily do.

　　Easy to operate on the Internet

Flash made with the courseware is very easy to publish online, Exchange. Flash can also produce a movie to generate a stand-alone executable file (. exe), without a Flash player in the computer platform to run, so, in addition to the production of web pages, courseware can also be applied to business demonstrations and electronic greeting card production. In addition, many multimedia software can directly use flash production of movies (. swf), seamless integration of Flash compact, beautiful, scalable vector graphics and animation, rotating, scaling flash animation quality without loss.

If there is any flaw in making courseware with flash, I think the most important thing is that it is not enough to support the image file. Without specialized software, it is not possible to insert image files (. mpg,.dat,.avi) into Flash. Perhaps because Flash is mainly used to make web animation, and not specifically for the production of courseware, the image file does not support it is understandable.
