wiggle(.2,50)

(the 50 is assuming you have your opactiy set at 50 before applying the wiggle to generate the full 100%)

if its still too much just keep lowering the .2 

A wiggle with usually give you a smoother result than a random expression. Try a wiggle that generates at about .2 times a second.

the stars look like they were done in particular, a way to achieve them is to make a “sphere” emitter, turn the velocity to 0, and make the size of the emitter extend much bigger than your comp, 1500x1500x1500 is a good starting point. And it looks like the life was set at about 1 second and set the opacity over life to go from 0-100 and back down (theres a preset setting for that in the opacity over life). And the rest was just really basic camera movements.

instead of starting the script with “thisComp”, try starting it with “comp(“name of comp”)”

wow, great resource…this is going to keep me busy for a looong time. Thanks!

It would be easier to do in just your text animator. make your sentence and throw a wiggle and position animator on it and animate the range selector. If your not familiar there are many tutorials out there on text animators.

instead of trying to divide try multiplying times a negative number

So what exactly are you working with here? Multiple layers youve script pick-whipped to a null? If so have you tried just parenting the objects to the null and just putting a wiggle on the position and rotation of the objects?

[Eric Sanderson]

the project is done but i would definitely like to know for future reference.

you shouldnt need a script if you planned on keyframing it.

So if im understanding you right you dont need so much of a “springy” action as you do just bounce or recoil from something dropping and hitting the ground?

[Eric Sanderson]

freq = 5;
amp = 125;
decay = 3;

z = amp*Math.cos(freq*time*2*Math.PI)/Math.exp(decay*time);
value + [0,0,z]

theres a few ways to do it, none any more simple than the other, heres one…and this is assuming your doing a Math.sin or .cos*Math.exp(time) expression for the spring action.
