Example details the properties of instances in Flash

Detailed

Original tutorial, reproduced please indicate the source: Web Teaching Network

When we make animation with flash, we always use symbols (components or components), there are three kinds of types: MC, BUTTON, GRAPHIC. When we press the F8 key, the object you select is converted to a symbol, but the essence of Flash is to interact, that is, we have to learn the action. When we drag a symbol from the library to the scene, then the symbol is called an instance. Usually when we use the action, some instructions call the instance name of the MC, and the instance of graphic is not callable.

When we call the MC first to the MC to set an instance name, in the action instruction we can make full use of the example to achieve special effects. For example: GetProperty (), setproperty () and so on! During the invocation of an instance, we usually change its properties to achieve the effect. We already know that using these movie properties can design a lot of dazzling effects, but perhaps many readers are not really familiar with it. Proficient in mastering and using these movie properties, not only can improve the programming ability of their own flash. If in time, your flash level will be "higher".

First give you 2 examples to let you understand: finally provide you with the source file download

　　 Example 1:

　　 Example 2:

So what are the properties of the instance? Specifically, describe the properties of the instance:

Property name	Description description
_alha	Transparency, expressed as a percentage, 100% indicates opacity, and 0% is transparent.
_accprops	Availability. screen reader Accessibility options for controlling SWF files, movie clips, buttons, dynamic text fields, or input text fields at run time. These properties override the settings provided in the accessibility panel at authoring time. In order for the changes to these properties to take effect, you must invoke Accessibility.updateproperties (). For information about the accessibility panel, see the Accessibility panel for Flash. To determine whether your player is running in an accessibility-enabled environment, use System.capabilities.hasAccessibility.
_currentframe	The frame number that the current movie or movie fragment symbol instance plays.
_droptarget	When the first movie fragment instance is dragged onto the second movie fragment symbol instance, it is set to the name of the movie fragment symbol instance that was last dragged to.
_focusrect	Whether the button symbol in the movie displays a yellow border when you use the TAB key to toggle the focus. The yellow border is displayed by default, and when set to 0 o'clock, the button symbol's up state is displayed.
_frameloaded	Returns the number of frames completed for download over the network. Often used during pre-download.
_height	The height of the movie fragment symbol instance, or the height of the movie, in pixels.
_highquality	Visual quality settings for movie films. 1 is low, 2 is high, 3 is best.
_name	Returns the name of the movie fragment symbol instance.
_quality	Returns the playback quality of the current movie.
_rotation	The angle that the movie fragment symbol instance rotates in relation to the vertical direction. But with property rotation, small changes in size can occur.
_soundbuftime	The sound in Flash is downloaded and played before playback, which indicates the time of the download.
_target	A string that specifies the exact character of the movie fragment symbol instance. Often used when using tell target.
_totalframes	Returns the total number of frames for a movie or movie fragment symbol instance on the timeline.
_url	Returns the full path name of the SWF file.
_visible	Specifies whether the movie fragment symbol instance is displayed: 1 is displayed, and 0 is not displayed.
_width	The width of the movie fragment symbol instance, or the width of the movie, in pixels.
_x	The horizontal distance between the center point of the movie fragment symbol instance and the upper-left corner of the stage where it is located. When a movie fragment symbol instance moves, it changes the value dynamically, in pixels. Needs to be used with the property panel.
_xmouse	Returns the position of the mouse pointer relative to the level of the stage.
_xscale	The percentage of the movie fragment symbol instance's scaling relative to the actual width of its parent class.
_y	The vertical distance between the center point of the movie fragment symbol instance and the upper-left corner of the stage where it is located. When a movie fragment symbol instance moves, it changes the value dynamically, in pixels. Needs to be used with the property panel.
_ymouse	Returns the position of the mouse pointer vertically relative to the stage.
_yscale	The percentage of the movie fragment symbol instance's scaling relative to the actual height of its parent class.
