Chapter II ActionScript 3.0 learning to draw stars (mouse and keyboard events)

Today I think it is more interesting to learn, so record it ... ~ ~ ~

The following paragraph is the code that paints the stars: starshape.as

Package {Import Flash.display.shape;import Flash.display.gradienttype;public class Starshape extends Shape {public function Starshape (X:number = 5, Y:number = innerradius:number, Points:int =, = +, Outerradius:number =-angle): Number = 0, Color:uint = 0xff0000) {//x and Y are the starting point ~~var count = Math.Abs (points); This.graphics.lineStyle (2, 0x85db18);// Start Fill color this.graphics.beginFill (color), if (Count > 2) {//init Varsvar step, Halfstep, start, N, DX, dy;//calculates the distance between two points step = (M Ath. PI * 2)/points;halfstep = step/2;//start angle start = (angle/180) * Math.pi;this.graphics.moveto (x + (Math.Cos (start) * out)  Erradius), Y-(Math.sin (START) * Outerradius));//Draw The Edge for (n = 1; n <= count; n++) {dx = x + math.cos (start + (step *) of the star graph) N)-halfstep) * Innerradius;dy = Y-math.sin (start + (STEP * N)-halfstep) * Innerradius;this.graphics.lineto (dx, dy); DX = x + math.cos (start + (step * N)) * Outerradius;dy = Y-math.sin (start + (step * N)) * Outerradius;this.graphics.line to (dx, DY);}} This.graphics.endFill();}}} 

The following results are shown:

Mouse click and keyboard press event exercises (press the button is Alt,shift,ctrl, single or 22 combination, three together, click the mouse):

Effect:

Can test the above click Results Oh, Hee ~ ~ Beginner Notes!! Don't puke, Auntie.
