1.First step is to make gradient source movie clip that make fire color and shape :

Use createCustomGradientMovieClip(..) function from MovieEx class to create custom gradient Movie Clip and pass drawFunc parameter which is a pointer to function which make a movie clip egg shape.

  //create gradient movie that form the fire color
  mcEx.createCustomGradientMovieClip(mcFire,"fireGradientSource",drawFunc,9,colors,alphas,ratios,
  "pad","LinearRGB",0,new Point(0,0),null,width,height,90); 

2.Second step need to create flame granularity texture.

Create perlinNoiseBitmap by using perlinNoise(...) function. Code that makes flame granularity in FireClass:


//creation of perlin noise bitmap for flame granularity
classObject.perlinNoiseBitmap.perlinNoise(classObject.sampleSize/2,classObject.sampleSize,3,
classObject.rnd,false,true,1,true,classObject.noiseOffsets);
