分享几个比较有用的脚本ease in/out效果的脚本

ease_linear

/// @function  ease_linear(time, start, change, duration)
/// @param time
/// @param start
/// @param change
/// @param duation

var t = argument[0];//time
var b = argument[1];//begin(start)
var c = argument[2];//change
var d = argument[3];//duration
 t /= d;

return c*t + b;

ease_in

/// @function  ease_in(time, start, change, duration)
/// @param time
/// @param start
/// @param change
/// @param duation

var t = argument[0];//time
var b = argument[1];//begin(start)
var c = argument[2];//change
var d = argument[3];//duration
 t /= d; 
return c*t*t*t + b;

ease_in_out

/// @function  ease_in_out(time, start, change, duration)
/// @param time
/// @param start
/// @param change
/// @param duation

var t = argument[0];//time
var b = argument[1];//begin(start)
var c = argument[2];//change
var d = argument[3];//duration
 t /= d/2;
if(t <1)return c/2*t*t + b;
t--;
return-c/2*(t*(t-2)-1)+ b;

ease_out_elastic

var t = argument[0];//time
var b = argument[1];//begin(start)
var c = argument[2];//change
var d = argument[3];//duration

var s =1.7;
var p =0;
var a = c;
if(t==0)return b;
t/=d;
if(t==1)return b+c;
if(!p) p=d*0.4;//effect bounce
if(a<abs(c)){
a=c;
s=p/4;
}else{
s=p/(2*pi)*arcsin(c/a);
}

return a*power(2,-10*t)*sin((t*d-s)*(2*pi)/p)+c+b;
