After doing some research I see that I cannot have my If/else statement inside of a variable like I had. As well as after the && I needed to add back in the “Rot” variable.

And also I pasted my code wrong in the forum :P.


//Old expression
Rot = transform.rotation;
Ctrl = thisComp.layer("Controller").effect("Width")("Slider");
Factor = if(Rot >0 && <90) {
Rot;
} else if(Rot >90 && <180) {
180 - Rot;
} else if(Rot >18 && <270) {
180 - Rot;
} else if(Rot >270 && <360) {
(360 - Rot)*-1;
} else

value;

Factor * Ctrl;


So instead I moved my slider controller into the If/else. And I fixed some of my math. Plus the 90º and 270º needed their own statements.
If anybody has a cleaner / better way of doing this please let me know. I've been trying my hardest to write everything from scratch and I am getting better, but i know I may be doing things the long and hard route. Haha


//New Code
Rot = transform.rotation.value;
Ctrl = thisComp.layer("Controller").effect("Width")("Slider");
if (Rot >0 && Rot <90) {
(Rot * Ctrl);
} else if(Rot == 90) {
(Rot)* Ctrl;
} else if(Rot >90 && Rot <180) {
(180 - Rot)* Ctrl;
} else if(Rot >180 && Rot <270) {
(180 - Rot)* Ctrl;
} else if(Rot == 270) {
(-90)* Ctrl;
} else if(Rot >270 && Rot <360) {
(360 - Rot)*-1 *Ctrl;
} else
0;

This worked perfectly!
It also worked to give my particles inertia!

Thanks a bunch Dan!

Also I use your alpha triggers animation expression all the time! Great stuff!
