Sample text

FillRect(0,0,wid,hei); 3. Draw the star by calling the createStar function: createStar(context,wid/2,hei/2,7,20,5,"#ffffff",null,0); 4. Create the createStart function: function createStar(context,baseX,baseY, innerRadius,outerRadius, points,fillColor, strokeColor,tilt){ // all the rest of the code in here } 5. From this point on we will be working within the createStart function. PI/180; var radianStepper = radian * ( 360/points) /2; var currentRadian =0; var radianTilt = tilt*radian; 6. beginPath(); 7.

Cos(currentRadian + radianTilt) * innerRadius); } We start a loop based on the number of points in our parameter. In this loop, we go back and forth between the external radius and the internal one each time we draw two lines between the inner circle and the external one. Our step size is defined by the number of points (the value we configured with the radianStepper variable). We covered the rest of the functions when we created the createTriangle function in an earlier recipe. There you have it!

Cos(currentRadian + radianTilt) * innerRadius); 8. cos(currentRadian + radianTilt) * innerRadius); } 32 Chapter 1 9. stroke(); } } When you run your HTML wrapper, you will find your first star and with it another flag will be under your belt. How it works... Let's start by understanding what the function we are going to create expects. The idea is simple, to create a star we want to have a virtual inner circle and a virtual outer circle. We can then draw lines between the circles back and forth to create the star.
