Linear interpolation to hold interpolation expression

[Dan Ebberts]

Maybe like this:

if (t < (tMin+tMax)/2) value1 else value2

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

[Dan Ebberts]

OK, so the output changes when the value becomes greater than the maximum value and doesn’t change back until it becomes less than the minimum value, is that correct? If so, that’s a much more complex expression, which will have to examine previous frames to see how input got to its current value.

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

Sorry–I’m a little lost. If there’s a one-to-one correspondence between input values and output values, that’s easy. If the output value depends at all on the history of the input value, that’s a different story. I can’t tell which case we’re talking about here.
