"HTML" option, the system will automatically generate a "HTML" web page file with the same name.
Two, Fash development of sports network multimedia courseware structure design
The use of Fash production of sports network multimedia teaching courseware, we must carefully study the characteristics of the Fash writing system and the realization of the method, and according to its characteristics, reasonable, scientific construction of a reasonable overall structure of the courseware layout, so that the overall structure of the courseware logical, clear structure, simple and easy to read. Development of courseware structure of common types are: animation simulation demonstration courseware, single scene interactive, multi-scene navigation type, program script class, practice and test class. According to the author's experience accumulated from practice, Fash development of sports network multimedia courseware structure is usually used multi-scene navigation type. Multi-scene navigation type courseware structure is generally composed of three parts: cover, teaching content, and back cover. Cover mainly explains the name of the multimedia courseware, the author, copyright, etc., generally using graphics, animation, sound and other means to enhance the artistic atmosphere and infectious courseware; back cover mainly explains the multimedia courseware information sources, acknowledgements and so on. Teaching content consists of the main interface and learning modules, of which the learning module is the core part of the courseware, and the learning content consists of a number of learning modules. In order to realize the network application of courseware, each learning module can be made into an independent Fash file, and LoadMovie command can be used to realize the mutual call between each learning module. The courseware designed with this idea can make the courseware with strong network characteristics, which is conducive to the maintenance and sustainable development of courseware. Modular structure design courseware is characterized by the playback of all the courseware modules do not need to be loaded into the computer's memory, just load the main control module of the courseware, and then, when needed, by clicking on the control buttons on the main control interface, the other courseware modules loaded to run. Through this structural design, a large sports multimedia courseware is decomposed into a number of small courseware, because the size of a single small courseware is small, easy to download and play in real time on the network, and can give full play to Fash streaming media-based communication technology.
Three, the use of Fash production sports network multimedia courseware
1. Text processing
In the sports network multimedia courseware in the appearance of the text is common, Fash can edit the text content, change the shape of the characters, set the text attributes, the text can be moved like a graphic object, rotate, deformation, but also according to the needs of the production of the text of the animated such as the title of the courseware can be produced "light and shadow, flying text" and other effects to enhance the attractiveness of the courseware. Fash can also be imported into the external text Fash and support CSS, so that it is convenient to change the text style without changing the Fash source program, reducing the size of the file, more suitable for network play.
2. Graphics
Fash software can draw a variety of graphics, support for the import of many types of existing graphic formats, including vector format and bitmap format, Fash can use its own tools for simple modifications to the graphics, artistic processing, the processing of the picture of the requirements of the higher, you can use Photoshop Cs, CorelDraw and so on. Picture processing software to process the picture and then imported into Fash, in order to meet the requirements of courseware designers. It is worth mentioning that before importing the bitmap format can be reduced according to the need to reduce the file or imported after the vectorization process, so that you can reduce the size of the file after generating courseware.
3. animation design
Fash animation has a variety of forms, there are frame-by-frame animation, motion complementary animation, shape complementary animation, guiding layer animation, mask animation, the use of Action Script programming design. For example: in explaining the rules of soccer offside, in order to let students understand what the offside, you can use Action Script to design a demo board, using the mouse to drag the players on the field and the ball to explain to the students, the students will be very clear, and then you can use frame-by-frame animation designed to slow down a frame by frame play, to see the passing of the ball a moment, whether the players are in the offside position, the students will deepen their understanding. Such as in the explanation of the jerky long jump action, you can use the movement to guide the layer animation, so that the jump angle along the design of the parabolic guide layer jump, air, landing. The parabola is designed to be low arc, medium arc and high arc, and then make low arc, medium arc and high arc buttons respectively. When the corresponding buttons are clicked, the athletes jump, vacate and land along the three routes respectively, so that the students can better understand the effect of the jumping angle on the distance. In the process of making courseware, suitable forms of animation should be adopted according to the characteristics of the teaching materials and the actual needs. Frame-by-frame animation designed with Fash takes up more space than motion complementary animation and shape complementary animation, and it is recommended to use less frame-by-frame animation, so that the size of the movie can be minimized to make the animation volume smaller, which is conducive to the playback of the animation and the transmission on the Internet.
4. Sound processing
Fash supports MP3 compression format and streaming sound playback technology. In sports multimedia courseware, sound is a very important component. With the emergence of MP3 format sound files, sound files than the original to be much less, the use of GoldWave software can be arbitrary interception of MP3 files. In Fash, you can also break up the sound file in Fash's smallest time unit of a frame for playback. This ensures that the sound and image synchronization can be achieved when playing on the Internet.
5. Video processing
Flash8 supports video MPEG, MOV, DV, AVI, etc., in Flash8, you can scale, rotate, distort and other processing of imported objects. Sports multimedia courseware often have to insert video clips of the game, sports technology, such as slow play, it is necessary to cut the film, editing, format conversion and other processing, the software commonly used in this regard are Premiere., After Effects and Acoustic Video and so on.
6. Interaction
Fash provides a wealth of means of interaction, mainly: button interaction, Fash can create buttons and buttons set up for a certain event occurs when the action to be performed. In Fash, the button can be any object on the Fash stage, such as text, graphics, pictures and other elements; menu navigation, Fash can produce a variety of menus, such as drop-down menus. Through the menu, you can play the various parts of the Fash movie as needed, just like the book directory, it is convenient for students to browse the required parts; Form Interaction, form is the buttons, animation, editable text box organization together, through the form can be passed to other local applications or remote services, mainly used in online surveys, ratings, search interfaces, etc.; Text Interaction, Fash can be text interaction, Fash can create editable text boxes, and can set editable text box properties such as the length of the input characters, single line or multi-line, font size and so on. Commonly used in multimedia courseware when the user needs to input content. In fact, it is usually a combination of several interaction methods, such as the creation of an object that is both animation and buttons, so that it can play a certain animation and can accept mouse events. Comprehensive use of these interactive features in Fash, can be used to create any playback control, jump set the button with a rich interactive sports multimedia courseware.
Four, Fash production of sports network multimedia courseware should pay attention to the problem
1. Production of an excellent Fash courseware, not only need to teachers teaching experience and knowledge structure of the support, but also requires the producer with planning, design, art, animation, music, programming capabilities, etc., physical education teachers only to continue to strengthen their own information technology in order to produce a good Fash courseware.
2. In the use of Fash courseware development process, the majority of physical education teachers should focus on the use of modern educational concepts, modern educational technology, system concepts to solve practical teaching problems, and seek to optimize the teaching effect. Fash network multimedia teaching courseware as a complementary means of physical education teaching, should give play to its advantages, and face up to the traditional means of teaching the value of the practical in order to reasonably and correctly used in physical education. Utilized in physical education teaching.
