Circular motion y axis

When i put the rate to 0, the motion is backward, any help? (sorri my english)
The position expression:
radius=effect("Radio")("Slider");
rate=effect("Frecuencia")("Slider");
offset=effect("Offset")("Slider");
angle=time*rate+offset;
x=radius*Math.cos(degreesToRadians(angle));
y=transform.position[1];
z=radius*Math.sin(degreesToRadians(angle));
centre=thisComp.layer("Null 1").transform.position;
add(centre,[x,y,z])

Hi Dan! hope your day is going well!

Let me ask you a question.. I saw a UI script someone created that when the mouse is over a button, a small description comes at the bottom of the script that looks like statictext but changes when the mouse goes over other buttons.

because the file is encrypted I was not able to open and learn how its done, would you happen to know?

I been playing all morning trying using the event listener and handler, but not sure if thats how its done. and how can you tell the handler to change whichever info in the statictext.

Thank you for your time!!

Take care,

Hi Dan, could you plese lend me a hand? I was able to write this script and works perfect as long as a project was open in after effects before running the script. But I noticed that if I just opened AE and run the script, it gives me an error at: line3: var projName = proj.file.name.replace(/%20/g, " ");

I understand that the error is happening because it can not find an open file name when AE just opened... but how can I avoid this error?

var my_file = new File("/Volumes/XSANESN/CreativeServices/Projects/ON_AIR_PROMOS/RED_SOX/15_RED_SOX/15_RED\ SOX\ TUNE\ INS/Graphics/RS_Tune_In_Toolkit/RS_Tune_In_Toolkit.aep");
var proj=app.project;
var projName = proj.file.name.replace(/%20/g, " ");



if (projName == null){
new_project = app.open(my_file);
}
else {

if (projName == my_file.name){
alert(projName + " IS ALREADY OPEN");
}
else{
if (my_file.exists){
new_project = app.open(my_file);
}
else {
new_project2 = app.open();
}
}
}
if (new_project){
alert(projName + " IS NOW OPEN, ENJOY");

Hi Dan! First of all Im so please to meet you. You are an inspiration to everyone, certainly to me. I been following your responses to everyone and trying to learn as much as I can about scripting. I have to say I truly fall in love with it. Still a newbie with so much to learn.

In the meantime, if its not to much to ask, I would love if you can take a look to my latest question... I havent been able to find an answer on my own.

Hi Dan,
Wanted to message you here instead of creating a separate forum post.

I am creating a 2.5 D parallax scene controlled through a null object. Thanks to you now I am able to use that expression code you helped me understand for this project.
I would like to ask a separate question, its again pretty simple and could be very noobish.

Problem :
When I space out 3 or more layers in the Z axis (depth) the layer that is farthest from the camera appears to be slightly faded than the ones close to the camera.
I m sure this is a simple FOV / Depth issue which can be corrected, can you advice me what to do here ?
