Create a custom MovieClip.drawSimpleRectangle( ) method using the Drawing API and invoke it on a movie clip. To draw a simple rectangle, specify the stroke's attributes using the lineStyle( ) method and then draw four lines using the lineTo( ) method: // Create rectangle_mc with a depth of 1 on the main timeline.
_root.createEmptyMovieClip("rectangle_mc", 1);
// Specify a one-pixel, solid, black line. // Draw four lines to form the perimeter of the rectangle. rectangle_mc.lineTo(100, 0); rectangle_mc.lineTo(100, 50); rectangle_mc.lineTo( 0, 50); rectangle_mc.lineTo( 0, 0); Thus, drawing a simple rectangle is no huge feat. To draw multiple rectangles with various dimensions, you should create a custom drawSimpleRectangle( ) method for the MovieClip class, as follows: // Define the custom method on MovieClip.prototype so that it's available to all
// movie clip instances.
MovieClip.prototype.drawSimpleRectangle = function (width, height) {
this.lineTo(width, 0);
this.lineTo(width, height);
this.lineTo(0, height);
this.lineTo(0, 0);
}
// Invoke the custom method like this.
_root.createEmptyMovieClip("rectangle_mc", 1);
rectangle_mc.lineStyle(1, 0x000000, 100);
rectangle_mc.drawSimpleRectangle(100, 50);
The dimensions of the rectangle are 102 x 52 pixels due to the line thickness. Reduce the dimensions by two pixels in each direction to create a rectangle whose outside dimensions match the intended size.

Create a custom MovieClip.drawTriangle( ) method using the Drawing API and invoke it on a movie clip. You can determine and plot the vertices of a triangle given the lengths of two sides and the angle between them. This is a better approach than specifying the lengths of the three sides because knowing the lengths of two sides and the angle between them always determines a triangle, whereas three arbitrary sides may not fit together to make a triangle. The custom drawTriangle( ) method accepts six parameters: ab ...
2. ActionScript: Filling a Shape with a Solid or Translucent Color
Use the beginFill( ) and endFill( ) methods to initiate and close a shape drawn at runtime. To draw a filled shape, call beginFill( ) prior to any other drawing methods, including the custom methods you have defined such as drawCircle( ) and drawPolygon( ). Invoke endFill( ) after calling other drawing methods to create the shape. You cannot apply a fill to an existing shape drawn at authoring time or runtime. You must invoke beginFill( ) before drawing the shape to be filled. This example creates a solid blue ...

You want to draw a rectangle with rounded corners, an offset, or rotation.Create a custom MovieClip.drawRectangle( ) method using the Drawing API and invoke it on a movie clip. The drawSimpleRectangle( ) method is, as the name suggests, quite simple. Let's create a more complex version that also: Draws a rectangle with a specified angle of rotation Let's you specify the rectangle center's coordinates Can draw a rectangle with rounded corners The drawRectangle( ) method accepts...
4. Reusing and Organizing Code in Flash Movies
You want to reuse code that you've created for one project in another Flash movie. Or you want to write your ActionScript code in an external text editor. Place your ActionScript code in external .as files and use the #include directive to add them to your Flash movies: // Adds all the code within MyActionScriptFile.as to your Flash movie. #include "MyActionScriptFile.as" Use the #include directive to incorporate code from external text files into your Flash movie during compilation from a .fla file ...
Create a custom MovieClip.drawCircle( ) method using the Drawing API and invoke it on a movie clip. You can create a circle in ActionScript with eight curves. Fewer curves results in a distorted circle and too many curves hinders performance. Let's create a custom method of the MovieClip class for drawing circles. This method, drawCircle( ), allows for three parameters: radius The radius of the circle x The x coordinate of the circle's center point. If undefined, the circle is centered at x =...
6. ActionScript: Repeating a Task at Timed Intervals
You want to perform an action or actions at a specific timed interval. Use the setInterval( ) function. The setInterval( ) function allows you to specify an interval (in milliseconds) at which your Flash movie will invoke a function. Use setInterval( ) to perform a particular action over time but not necessarily at the frequency of the frame rate of the movie. // Define a function. function myIntervalFunction ( ) { // Output the difference between the current timer value and its value from the ...
7. Mouse Location Flash Script
Not only can you get the location of a movie clip on the screen, you can even get the location of the mouse, also known as the cursor. What is the difference between the mouse and the cursor? The mouse is the physical device attached to your computer. You may even have a track pad or tablet instead. The cursor is the graphic that moves around the screen as you move your mouse. So, technically, cursor is the term I should be using here. However, ActionScript uses the term mouse in its keywords. I will therefore use mouse and cursor i...
8. ActionScript: Performing Actions Conditionally
You want to perform an action only when a condition is true. Use an if statement or a switch statement. You often need your ActionScript code to make decisions, such as whether to execute a particular action or group of actions. To execute an action under certain circumstances, use one of ActionScript's conditional statements: if, switch, or the ternary conditional operator (? :). The conditional statements allow you to make logical decisions, and you'll learn from experience which is more appropriate for a given situ...
9. Enhancing Standalone Projector
You want to create an enhanced Standalone Projector with features such as borderless playback, custom titles, no Flash menus, and so on. Use a third-party tool such as SWF Studio or SWFKit to create the Projector from your completed Flash movie. SWF Studio is a third-party utility that helps you overcome some of the limitations of regular standalone Flash Projectors. However, SWF Studio produces Windows projectors only. Also note that the resultant projector files are rather hefty (minimum file size is around 1.5 MB). The...
