This expression in the position property of the null should work:

p = thisComp.layer(“2D object”).transform.position.value;
p[2] = thisComp.layer(“3D object”).transform.position.value[2];

p;

This should work:

x = effect("value")("Slider");
holdTime = 2;
holdTimeErr = 0.5;
rdmTime = 10;
rdmTimeErr = 2;
hold = false; // change to true to start with a value on hold;

f = timeToFrames(inPoint);
F = timeToFrames(time);
h1 = timeToFrames(holdTime-holdTimeErr);
h2 = timeToFrames(holdTime+holdTimeErr);
r1 = timeToFrames(rdmTime-rdmTimeErr);
r2 = timeToFrames(rdmTime+rdmTimeErr);
while(f

Try change the line:

fDist=length(mCam,mPos);

with:

fDist=Math.abs(mCam[2],mPos[2]);

To retrieve that number, you can use

num = 0;
str = “01_”;

N=thisComp.numlayers;
for (n=1; n<=N; n++){if (thisComp.layer(n).name.indexOf(str)===0) ++num;}; // at this stage, num is the number of layers in the comp whose name starts with "01_". // then you use it to calculate your position offset. Xavier

Set the alignment like this:

shortcuts.structBtn1.alignment = [‘fill’, ‘top’];

(view the (Adobe/pdf) JavaScript_Tools_Guide for more details).

* To ask for the folder path, you can use:

var myPresetsFolder = Folder.selectDialog();

or :

var allPresetsFolder = Folder(Folder.appPackage.absoluteURI + “/” + “Presets”);
var myPresetsFolder = allPresetsFolder.selectDlg();

(The 2 methods dffer in that in the latter case the dialog “has already navigated to a closer place”.)

* To read/write in the prefs file, use the app;settings object:

var allPresetsFolder = Folder(Folder.appPackage.absoluteURI + "/" + "Presets");
var myPresetsFolder;

// read the settings
if (app.settings.haveSetting("MyScriptSection", "myPresetsFolderPath")){
myPresetFolder = new Folder(app.settings.getSetting("MyScriptSection", "myPresetsFolderPath"));
};
if (!myPresetFolder || !myPresetFolder.exists){
// if the folder does not exist, ask for the path
myPresetsFolder = allPresetsFolder.selectDlg();
if (myPresetsFolder && myPresetsFolder.exists){
// if now it exists, save the path
app.settings.saveSetting("MyScriptSection", myPresetsFolder.absoulteURI);
};
};
// Beware, at this stage the variable myPresetsFolder can still be null, if the user was prompted a folder dialog and closed it.

Hi,

in case the scale varies when the null hover over the layer, you can use something like this, which is quite simple since it will be the same expression for all cards:


x = Math.abs(thisComp.layer("mov scale").transform.position[0] - transform.position[0]);
fadeDist = 500;
s = ease(x, 0, fadeDist, 100, 75);
[s,s];

If the numbers you indicate do not correspond to any layer position, then:

x = Math.abs(thisComp.layer(“mov scale”).transform.position[0] – 1161.3);
fadeDist = 1161.3 – 662.7;
scalex = ease(x, 0, fadeDist, 100, 75);
[scalex,scalex];

Expressions must be self-contained and cant use buffers.
At each frame, the expression code must look forward and backwards to see if there are enugh frames above threshold or not.
I didnt try but the following should work:

threshold = 0.5; // minimum amplitude
fMin = 15; // minimum number of frames above threshold
L = thisComp.layer("Audio Amplitude");
ampSlider = L.effect("Both Channels")("Slider");
if (ampSlider.value<=threshold){
0;
}
else{
f = 1;
dt = thisComp.frameDuration;
// search backwards
t = time;
while( f<fMin && L.inPoint<=(t-=dt) && ampSlider.valueAtTime(t)>threshold && ++f);
// search forwards
t = time;
while( f<fMin && ((t+=dt)<=L.outPoint) && ampSlider.valueAtTime(t)>threshold && ++f);

f<fMin ? 0 : 100;
};

When you add a new effect to a layer, previous references to anything inside the layer effects get invalidated.
If you need to add several effects and keep a reference to all of them during the execution of the script, you should wait to have set them all to declare variables.

var myComp=app.project.activeItem;
var myLayer=myComp.selectedLayers[0];
var myMask=myLayer.mask(1);

var N=myLayer.numProperties;
myLayer.property(“Effects”).addProperty(“Point Control”);
myLayer.property(“Effects”).addProperty(“Slider Control”);

var Target=myLayer.property(“Effects”).property(N+1);
Target.name=”myTarget”;
var myTarget=Target.property(“Point”);

var mySlider=myLayer.property(“Effects”).property(N+2);
mySlider.name=”mySlider”;

N+=2;// the actual number of effects now

The selection of a dropdownlist is a ListItem or null, so in any case, typeof mydropdownlist.selection should be “object”.
In the console: $.writeln(mydropdownlist.selection) will be either “null” or the selected item text property (not its index). The string is not the selection itself, it is a display string for the selection.

And to set the selection you can do either of:

// selection by index:
dd.selection = dd.items[0];
dd.selection = 0;

// selection by text (it will be the first item that carry that text, or null if not found)
dd.selection = dd.find(someText);

And may be some other ways.
