rescaling numbers

[Rob Dahl]

Well…

See code for one way to do it.
I created a Comp with two objects on it.
Object 1 is Dark Blue Solid 1 50 px square.
Object 2 what a White solid 50px square.
On the While box I added a Gaussian Blur.
Below was the code I created for the Blurriness control.

I am sure others will provide another way.

loc_obj1=thisComp.layer("Dark Blue Solid 1").transform.position[0]; // get object 1 X location
loc_obj2=transform.position[0]; //get object 2 X location
delta_Objs=loc_obj2-loc_obj1; // Determine the distance between Object 2 and 1
Cntr_space=2748-1064; // The controlled space defined for blur
Multiplier=51/Cntr_space; // The controlled space linearly divided for 0-50
delta_Blur=Multiplier*(delta_Objs-1064); // The point at which the blur starts. Final line - The blur effect applied until 50, then blur is constant.
if(delta_Blur<=50){delta_Blur}else{50}

If there aren’t any parents involved, it could be as simple as this:

p1 = thisComp.layer(“layer 1”).transform.position;
p2 = thisComp.layer(“layer 2”).transform.position;
linear(length(p1,p2),1064,2748,0,50);

Wow, I really appreciate this guys, but I think a friend an I came up with a much solution before I had a chance to come back here.

50/(2282-1064) = 0.0410509… (ratio number)
then I inserted that ratio number in my equation in my Gaussian Blur expression on the object I with to blur:

x = (thisComp.layer(“dolly”).transform.position[2] – transform.position[2])*-1;
(x – 1064)*0.0410509;

if (x > 4000){
120
}

where “dolly” is, that’s the null object I use to control my camera. It’s “*-1” cause all my number info is in the negative due to where my objects are in the scene. And if the distance is more than 4000 than stay blurred at 120.

Thanks to all who came up with ideas for me.
