Jumpy Hold WIGGLE

Have you ever wanted to wiggle something, but have it jump around instead of linearly animate?
Code: Select all
v=wiggle(5,50);
if(v < 50)v=0;
if(v > 50)v=100;
v
modify the numbers are necessary.. enjoy

forgot to clarify that in this example wiggle will vary the incoming property value by 50, so if this is opacity for example and it is set to 50, then wiggle will output values from 0 to 100.
I am just pointing this out because it can be a bit confusing since the output is then defined by the expression, in this case 0 or 100, not the values output by the wiggle (although in this case i set it up so it would essentially be the same). But you could for example set opacity to 1 and then wiggle that by 1 and set the expression as follows:
Code: Select all
v=wiggle(5,1);
if(v < 1)v=0;
if(v > 1)v=100;
v
and still get the same output of 0 or 100.

While the code i showed in the previous posts works well for single value arrays like opacity, it does not work so well for multi value arrays like position. This code works beautifully for position:
Code: Select all
fps=15; //frequency
amount=50; //amplitude
wiggle(fps,amount,octaves = 1, amp_mult = 0.5,(Math.round(time*fps))/fps);

ciao lloydalvarez
I looking for a list of EXPRESSIONS like this:
wiggle(100,100)
there is other simple expressions as that???
