Combining Ease and Wizz with another expression
Hi everybody,
and thanks for all your work! Thanks to this forum i could learn a lot about expressions and resolve a lot of issues by checking through all your post.But now is time for me to post my own issue:
I would like to combine an expression i wrote with the ease and wizz expression.
Basicly, I’m doing a sort of a template where i have this expression that scale the x value of a layer based on the value I put in a Null and according to his own keyframes.
I need to add the ease and wizz to this two keyframes (inOutQuint), but if i do it throught the script ease and wizz, my expression stops working.
I know it can’t work by pasting the ease and wizz expression below mine, but i have no idea how to combine them!
Can anybody help me with this?
Thanks a lot!MY EXPRESSION:
yScale = 100;
xScaleZero = 0;
xScaleMask = thisComp.layer(“SCALE LINES”).transform.scale[0];
min = [xScaleZero,yScale];
max = [xScaleMask,yScale];
t1 = key(1).time;
t2 = key(2).time
if (time<=t1) min;
else if (time>t1 && time// Ease and Wizz 2.0 : inOutQuint : All keyframes

// some defaults
var p = 0.8; // period for elastic
var a = 50; // amplitude for elastic
var s = 1.70158; // overshoot amount for "back"
function inOutQuint(t, b, c, d, a, p) {
if ((t/=d/2) < 1) return c/2*t*t*t*t*t + b;
return c/2*((t-=2)*t*t*t*t + 2) + b;
}
function easeAndWizz() {var n = 0;
if (numKeys > 0) {
n = nearestKey(time).index;
if (key(n).time > time) { n– }
}
try {
var key1 = key(n);
var key2 = key(n+1);
} catch(e) {
return null;
}// determine how many dimensions the keyframes need
var dim = 1; // It’s gotta have at least ONE dimension
try {
key(1)[1];
dim = 2;
key(1)[2];
dim = 3;
} catch(e) {}
t = time – key1.time;
d = key2.time – key1.time;
sX = key1[0];
eX = key2[0] – key1[0];
if (dim >= 2) {
sY = key1[1];
eY = key2[1] – key1[1];
if (dim >= 3) {
sZ = key1[2];
eZ = key2[2] – key1[2];
}
}
if ((time < key1.time) || (time > key2.time)) {
return value;
} else {
val1 = inOutQuint(t, sX, eX, d, a, p, s);
switch (dim) {
case 1:
return val1;
break;
case 2:
val2 = inOutQuint(t, sY, eY, d, a, p, s);
return [val1, val2];
break;
case 3:
val2 = inOutQuint(t, sY, eY, d, a, p, s);
val3 = inOutQuint(t, sZ, eZ, d, a, p, s);
return [val1, val2, val3];
break;
default:
return null;
}
}
}
(easeAndWizz() || value);

You should look into the Animation Patterns script. I think that one can combine multiple “patterns” or animations all referenced with expressions on the same parameter. Free version https://aescripts.com/animationpatterns/

Thank you very much Jason!
Actually I just spent all afternoon rewriting the entire expression (combining the two)
and at the end it worked! (i’m very surprised!)
But thanks anyway for your advice, i’ll have a look in case of any other evenience!If anyone could ever need it, it’s this:
yScale = 100;
xScaleZero = 0;
xScaleMask = thisComp.layer("SCALE LINES").transform.scale[0];
min = [xScaleZero,yScale];
max = [xScaleMask,yScale];
t1 = key(1).time;
t2 = key(2).time;// Ease and Wizz 2.0 : outQuint : All keyframes

function outQuint(t, b, c, d, a, p) {
return c*((t=t/d-1)*t*t*t*t + 1) + b;
}function easeAndWizz() {
var dim = 2;
t = time - t1;
d = t2 - t1;
sX = 0;
eX = xScaleMask - 0;
sY = 100;
eY = 100 - 100;if (time < t1) {
return min;
}
if (time > t2) {
return max;
} else {
val1 = outQuint(t, sX, eX, d, a, p, s);
switch (dim) {
case 1:
return val1;
break;
case 2:
val2 = outQuint(t, sY, eY, d, a, p, s);
return [val1, val2];
break;
default:
return null;
}
}
}
(easeAndWizz() || value);
