What you want is the velocity when the force is removed. For example, with this expression:

easeIn(time,0,1,[0,0],[500,500]);

You’d want to sample the velocity at 0.999 sec (right before the layer stops moving).

You could, but the expression would have to know when to pick up the velocity. What determines when Null A stops its motion?

try it like this:


function getItem(theName){
for (var i =1; i <= app.project.numItems; i++){
if ((app.project.item(i)) && (app.project.item(i).name == theName)){
return app.project.item(i);
}
}
return null;
}

function findComp(theName){
for (var i =1; i <= app.project.numItems; i++){
if ((app.project.item(i) instanceof CompItem) && (app.project.item(i).name == theName)){
return app.project.item(i);
}
}
return null;
}

function replaceFile(){

var compName = "mycomp";
var myComp = findComp(compName);
if (myComp == null){
alert("Can't find comp '" + compName + "'.");
return;
}
var myLayer = myComp.layer('pink.png');
var itemName = "blue.png";
var myItem = getItem(itemName);
if (myItem == null){
alert("Can't find item '" + itemName + "'.");
return;
}
myLayer.replaceSource(myItem,false);
}
replaceFile();


Also, if you post code in this forum, please don’t preview your post. It messes things up.

You could add a function to find a comp, like this (not tested):


function findComp(theName){
for (var i =1; i <= app.project.numItems; i++){
if ((app.project.item(i) instanceof CompItem) && (app.project.item(i).name == theName)){
return app.project.item(i);
}
}
return null;
}


If it returns null, the comp was not found.

Try this:


function getItem(theName){
for (var i =1; i <= app.project.numItems; i++){
if ((app.project.item(i)) && (app.project.item(i).name == theName)){
return app.project.item(i);
}
}
return null;
}

function replaceFile(){
var myComp = app.project.activeItem;
if ((myComp == null) || ! (myComp instanceof CompItem)){
alert("No comp active.");
return;
}
var myLayer = myComp.layer('blue.png');
var itemName = "pink.png";
var myItem = getItem(itemName);
if (myItem == null){
alert("Can't find item '" + itemName + "'.");
return;
}
myLayer.replaceSource(myItem,false);
}
replaceFile();

This should work:


inText = thisComp.layer("Same text, But without The final line").text.sourceText;
splitText = inText.split("\r");
outText = "";
for (i = 0; i < splitText.length-1;i++){
outText += (i == 0 ? "" : "\r") + splitText[i];
}
outText

The dropdown control is an unusual implementation. You could try this:


var dropdownItems = [
"Left",
"Center",
"Right"
];
var boxLayerDropdown = boxLayer.Effects.addProperty("ADBE Dropdown Control");
var temp = boxLayerDropdown.property(1).setPropertyParameters(dropdownItems);
temp.propertyGroup(1).name = "Align";

As far as I know, they’ve always worked. There’s an issue with single-line if else statements and the new engine, but I think that’s it.

Could be like this (depending on which one you want to have precedence.


posA = [100,100];
posB = [200,200];
posC = [300,300];

if (thisComp.layer("Layer 1").active)
posA
else if (thisComp.layer("Layer 2").active)
posB
else if (thisComp.layer("Layer 3").active)
posC
else
value

Something like this maybe:

linear(time,textIndex-.25,textIndex,0,100)
