Using the drawing API
package{
import flash.display.*;
public class DrawPathExample extends Sprite {
public function DrawPathExample(){
}
}
var square_commands:Vector. = new Vector.(5,true);
square_commands[0] = 1;//moveTo
square_commands[1] = 2;//lineTo
square_commands[2] = 2;
square_commands[3] = 2;
square_commands[4] = 2;
var square_coord:Vector. = new Vector.(10,true);
square_coord[0] = 20; //x
square_coord[1] = 10; //y
square_coord[2] = 50;
square_coord[3] = 10;
square_coord[4] = 50;
square_coord[5] = 40;
square_coord[6] = 20;
square_coord[7] = 40;
square_coord[8] = 20;
square_coord[9] = 10;
graphics.beginFill(0x442266);//set the color
graphics.drawPath(square_commands, square_coord);
}
In the above example, each command and coordinate pair is assigned individually to show their position in the array,
but they can be assigned in a single statement. The following example draws the same star by assigning the values for
each array in a single push() statement:
package{
import flash.display.*;
public class DrawPathExample extends Sprite {
public function DrawPathExample(){
}
}
var square_commands:Vector. = new Vector.();
square_commands.push(1, 2, 2, 2, 2);
var square_coord:Vector. = new Vector.();
square_coord.push(20,10, 50,10, 50,40, 20,40, 20,10);
graphics.beginFill(0x442266);
graphics.drawPath(square_commands, square_coord);
}
