AE表达式实现心形来回飘散的动画效果
今天为大家分享AE表达式实现心形来回飘散的动画效果方法，教程真的很不错，方法也很简单，适合新手来学习，来看看吧！
下面是具体的制作步骤：
1. 首先，先送大家一颗心。
2. 导入ae，花个mask稍微修饰一下，如图：
3.给位置加表达式：
代码如下:
tMin = .25; //minimum segment duration
tMax = 1.0; //maximum segment duration
minVal = ;
maxVal = ;
end = 0;
j = 0;
while (time %26gt;= end){
j ++;
seed_random(j,true);
start = end;
end += random(tMin,tMax);
}
endVal = random(minVal,maxVal);
seed_random(j-1,true);
dummy = random(); //this is a throw-away value
startVal = random(minVal,maxVal);
ease(time,start,end,startVal,endVal)
tMax = 1.0; //maximum segment duration
minVal = ;
maxVal = ;
end = 0;
j = 0;
while (time %26gt;= end){
j ++;
seed_random(j,true);
start = end;
end += random(tMin,tMax);
}
endVal = random(minVal,maxVal);
seed_random(j-1,true);
dummy = random(); //this is a throw-away value
startVal = random(minVal,maxVal);
ease(time,start,end,startVal,endVal)
4. 然后给scale加表达式：
代码如下:
tMin = .25; //minimum segment duration
tMax = 1.0; //maximum segment duration
minVal = 25;
maxVal = 70;
end = 0;
j = 0;
while (time %26gt;= end){
j ++;
seed_random(j,true);
start = end;
end += random(tMin,tMax);
}
s = random(minVal,maxVal);
endVal = ;
seed_random(j-1,true);
dummy = random(); //this is a throw-away value
s = random(minVal,maxVal);
startVal =
ease(time,start,end,startVal,endVal)
tMax = 1.0; //maximum segment duration
minVal = 25;
maxVal = 70;
end = 0;
j = 0;
while (time %26gt;= end){
j ++;
seed_random(j,true);
start = end;
end += random(tMin,tMax);
}
s = random(minVal,maxVal);
endVal = ;
seed_random(j-1,true);
dummy = random(); //this is a throw-away value
s = random(minVal,maxVal);
startVal =
ease(time,start,end,startVal,endVal)
5. 最后给旋转加表达式：
代码如下:
tMin = .25; //minimum segment duration
tMax = 1.0; //maximum segment duration
minVal = 0;
maxVal = 720;
end = 0;
j = 0;
while ( time %26gt;= end){
j ++;
seed_random(j,true);
start = end;
end += random(tMin,tMax);
}
endVal = random(minVal,maxVal);
seed_random(j-1,true);
dummy = random(); //this is a throw-away value
startVal = random(minVal,maxVal);
ease(time,start,end,startVal,endVal)
tMax = 1.0; //maximum segment duration
minVal = 0;
maxVal = 720;
end = 0;
j = 0;
while ( time %26gt;= end){
j ++;
seed_random(j,true);
start = end;
end += random(tMin,tMax);
}
endVal = random(minVal,maxVal);
seed_random(j-1,true);
dummy = random(); //this is a throw-away value
startVal = random(minVal,maxVal);
ease(time,start,end,startVal,endVal)
6. 然后，copy上n次，随你意愿，接着加hue命令，调下颜色。
7. 照死里压，终于小于了200k。
完成，谢谢大家。
