Perfect that is the solution or the error rather!!!, Thanks Dan

Hello Dan!!

I have used a couple of expressions, including the explained expression of here for make a “write on effect” to begin in the second 1, however the brush position is outside of the “myProp” variant, I have analyzed it, but I have not yet understood this. I attached a picture where I show this. Thanks!!

[Ale Elizondo]

How forever thanks Dan!!! 😀 this works perfect and you saved me a lot of time and problems.

There is an error on this line :/:

“Class global has no property or method named “t”

[Ale Elizondo]

Dan I have the same problem but with a little difference , could you help me with this?:

I try use your solution :

if (n > 0){

to this:

if (n > 0 && t < 1){

but this no works in this case:/

amp = .2;
freq = 3;
decay = 2;
kf = 2; // only on 2nd keyframe
 
n = 0;
if (numKeys > 0){
  n = nearestKey(time).index;
  if (key(n).time > time) n--;
}
 
if (n == kf){
 t = time - key(n).time;
  v = velocityAtTime(key(n).time - thisComp.frameDuration/10);
  temp = value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
  x = temp[0];
  y = value[0]*value[1]/x;
  [x,y]
}else
  value

Dan that works perfect!! 🙂

I used the same idea for interpolate between two layers of two dimension:

minY = 500;
maxY = 700;
minX=400;
maxX=600;
minScale = 0;
maxScale = 100;
y = thisComp.layer(“1”).transform.position[1];
linear(y,minY,maxY,[minScale,minScale],[maxScale,maxScale]);
x = thisComp.layer(“1”).transform.position[0];
linear(x,minX,maxX,[minScale,minScale],[maxScale,maxScale]);

[Ale Elizondo]

For example when the Scale of the first object is 100 the opacity of second object is 0 that is correct but when the scale changes to 99 the opacity changes to 100 this doesn’t work for what I want. This question was for properties of one dimension, I would like make it too with an interpolation between property of two dimension to one dimension, how from scale to opacity, I guess this will be more difficult XD.

Thanks for review this Dan

[Ale Elizondo]

Thanks for your response Dan.

I use this as follows:

t=thisComp.layer(“ojo 2”).transform.scale[1];
if (t < (0+100)/2) 100 else 0

this on Opacity property, but there are some problems :/

my idea is to invert the values ​​and this works but until the value is less than 50, I guess this is why the division is by 2, I want the change to happen until it reached the maximum or minimum value

[Ale Elizondo]

thanks dan!! 🙂

[Ale Elizondo]

Very helpful this 🙂

But this expression only works with properties of one dimension. How works it with a property of two dimensions? I hope you can tell me.
