Dynamic seperation of circle into segments

1

hi everyOne,

I have a gaming requirement in which i need to slice a pizza/cake into different parts depending upon a random generated no between (1-10) ie if 6 is generated i need to cut the cake into 6 different parts.I need to do this dynamicaly(through coding) rather than on time lines.

I am not understanding how to go abt it.Could anyone please help me.

Thanks in advance

You’ll need some basic trigonometry, I think.

Try this:

// where is the centre of the pizza?
var centreX = 150;
var centreY = 150;

// define the radius
var radius:uint = 100;

// create a sprite on which we'll do our drawing
var mySprite:Sprite = new Sprite();
mySprite.graphics.lineStyle(1);
mySprite.graphics.beginFill(0xffffff); // white


// draw the pizza and put it on the stage
mySprite.graphics.drawCircle(centreX,centreY,radius); 
mySprite.graphics.endFill();
addChild(mySprite);

// call the drawSlices function
drawSlices(7);


function drawSlices(numberOfSlices:uint):void
{
    // cuts the pizza into 'numberOfSlices' pieces
     if(numberOfSlices > 1)
    {
      for (var i:uint = 0; i < numberOfSlices; i++)
        {
            mySprite.graphics.moveTo(centreX,centreY); // centre of pizza
            
           // use trigonometry to find the point on the circumference of the
           // circle to which we draw a straight line
              
              var theta:Number = i*2*Math.PI/numberOfSlices; // angle in radians
            
              mySprite.graphics.lineTo(centreX + radius*Math.sin(theta), centreY +               radius*Math.cos(theta));
        }
     }
}
