Flash动画教程:AS制作美丽爱心效果动画

1:先在场景绘制一个任意形,图像也可以,f8转换为影片剪辑。

2:紧接着,按f8再转换一次影片剪辑"元件2"。

3:双击进入"元件2",给影片剪辑起名称为"aqua0"。

4:新建图层2,层2第一帧点右键,选择“动作”。

5:给第二层依次按f7插入三个空白关键帧.他们的action依次是

第一帧:

d = 0;

i = 0;

numAqua = 0;

minAlpha = 70;

  threshold = 500;

  clp = aqua0;

  maxChange = 1.57;

  maxChange2 = 1.04666666666667;

  halfMax = maxChange/2;

  halfMax2 = maxChange2/2;

  maxSpeed2 = 2;

  trajectory = new Array(15);

  trajectory[0] = 0;

第二帧:

  i = numAqua;

  while (i>=0) {

  baseClip = eval("aqua"+i);

  dx = baseClip._x-_xmouse;

  dy = baseClip._y-_ymouse;

  d = Number(Math.sqrt((dx*dx)+(dy*dy)));

  if (threshold
   d = threshold;

  }

  closeness = (Math.pow(((threshold-d)/threshold)*10, 1.8)*0.016)*100;

  if (!closeness) {

   closeness = 0;

  }

  if (0
   if (97
   if (baseClip._xscale<20) {

   removeMovieClip(baseClip);

   }

   if (numAqua<15) {

   numAqua = numAqua+1;

   duplicateMovieClip("aqua"+i, "aqua"+numAqua, numAqua);

   newClip = eval("aqua"+numAqua);

   trajectory[numAqua] = 0;

   colors[numAqua] = new Color(newClip);

   currentColor[numAqua] = new Object();

   colors[numAqua].setTransform(currentColor[numAqua]);

   newClip._x = newClip._x+(random(5)+5);

   newClip._y = newClip._y+(random(5)+5);

   baseClip._xscale = baseClip._xscale-20;

   baseClip._yscale = baseClip._yscale-20;

   newClip._xscale = baseClip._xscale;

   newClip._yscale = baseClip._yscale;

   }

   }

   currentColor[i].ra = startR-((closeness*0.01)*(startR-endR));

   currentColor[i].ga = startG-((closeness*0.01)*(startG-endG));

   currentColor[i].ba = startB-((closeness*0.01)*(startB-endB));

   colors[i].setTransform(currentColor[i]);

   a = (closeness*(100-minAlpha))*0.01;

   baseClip._alpha = a+minAlpha;

   speed = closeness/8;

   angle = (Math.random()*100)%maxChange;

   trajectory[i] = (trajectory[i]-halfMax)+angle;

  } else {

   currentColor[i].ra = startR-((closeness*0.01)*(startR-endR));

   currentColor[i].ga = startG-((closeness*0.01)*(startG-endG));

   currentColor[i].ba = startB-((closeness*0.01)*(startB-endB));

   colors[i].setTransform(currentColor[i]);

   a = (closeness*(100-minAlpha))*0.01;

   baseClip._alpha = a+minAlpha;

   speed = maxSpeed2;

   angle = (Math.random()*100)%maxChange2;

   trajectory[i] = (trajectory[i]-halfMax2)+angle;

  }

  vx = speed*Math.cos(trajectory[i]);

  vy = speed*Math.sin(trajectory[i]);

  baseClip._x = baseClip._x+vx;

  baseClip._y = baseClip._y+vy;

  i = i-1;

  }

第三帧:

gotoAndPlay(2);

6:基本上大功告成,回到场景,新建一个层,加个背景图就ok了,别忘了把背景图放到最下层哦。你也可以多复制一些调整大小,这个大家自己发挥了。
