Targeting Arbitrary Layers in ExtendScript
Hi all, Making a script that can allow me to ease my layers via shortcut. The problem I’m having is that I can’t seem to target a currently selected layer. I will share my code. Can anyone aid me with the logic of how to do this? I pretty much target with activeLay and numkeys. But I’ve only been successful at targeting the top layer. And a lot of efforts of changing up the target, using different methods. Please help if you can.
var activeLay = app.project.activeItem; // mod piece for layer 1 of active layer
//methods
var numkeys = app.project.activeItem.layer(1).position.selectedKeys; // method that gives an array of all keyframes
//numbers
//keyframes
//functiontotkeys active variables booleans\
//---------------------------
var posActive = false;
var opaActive = false;
var rotActive = false;
var scaActive = false;
var numAllKeys = 0; //will be the number of all keys
var numPosKeys = new Array;
var numRotKeys = new Array;
var numOpaKeys = new Array;
//------------------------------
//~ ------------------ begin script
functiontotalkeys(); // calling functiontotalkeys
function functiontotalkeys() //this function will bring back all keys then call filterme
{
alert("hi");
// formula call for position
var checkPosKey = activeLay.position.numKeys; //checking number of 'position" keys on layer 1
alert(checkPosKey);
//alert("this is the position key " + checkPosKey);
if (checkPosKey >= 1) // if there are any actual position keyframes then go ahead and iterate
{
for (var p = 1; p <= checkPosKey; p++)
{
alert("made it");
//alert("for loop is being called");
var keypos = app.project.item(2).layer(2).position.keySelected(p);
alert(keypos);
if(keypos == true)
{
alert(keypos + "HEYNOW");
var posmod = activeLay.property("Position");// position layer module of active layer + layer 1
var curPosKeyIn = activeLay.position.keyInTemporalEase(p)[0].influence;
var curPosKeySp = activeLay.position.keyInTemporalEase(p)[0].speed;
// //alert( "current influence is " + curPosKeyIn );
var uniEasePos = new KeyframeEase( curPosKeySp ,(curPosKeyIn += 1));
////alert( "current influence is now " + curPosKeyIn );
posmod.setTemporalEaseAtKey(p,[uniEasePos],[uniEasePos])
}
}
};
// formula call for rotation
var checkRotKey = activeLay.rotation.numKeys; //checking number of 'position" keys on layer 1
//alert("this is the position key " + checkRotKey);
if (checkRotKey >= 1) // if there are any actual position keyframes then go ahead and iterate
{
for (var r = 1; r <= checkRotKey; r++)
{

var keyrot = app.project.activeItem.layer(1).rotation.keySelected(r);

var curRotKeySp = activeLay.rotation.keyInTemporalEase(r)[0].speed;
//alert( "current influence is " + curRotKeyIn );
var uniEaseRot = new KeyframeEase( curRotKeySp ,(curRotKeyIn += 25));
//alert( "current influence is now " + curRotKeyIn );
rotmod.setTemporalEaseAtKey(r,[uniEaseRot],[uniEaseRot])
}
}
};
// formula call for scale
var checkScaKey = activeLay.scale.numKeys; //checking number of 'position" keys on layer 1
//alert("this is the position key " + checkScaKey);
if (checkScaKey >= 1) // if there are any actual position keyframes then go ahead and iterate
{
for (var s = 1; s <= checkScaKey; s++)
{
//alert("for loop is being called");
var keysca = app.project.activeItem.layer(1).scale.keySelected(s);
if(keysca == true)

//alert( "current influence is now " + curScaKeyIn );
scamod.setTemporalEaseAtKey(s,[uniEaseSca,uniEaseSca,uniEaseSca],[uniEaseSca,uniEaseSca,uniEaseSca])
}

// formula call for rotation
var checkOpaKey = activeLay.opacity.numKeys; //checking number of 'position" keys on layer 1
//alert("this is the position key " + checkOpaKey);

Something like this should give you the first selected layer:
var selectedLayers = app.project.activeItem.selectedLayers;
if (selectedLayers.length > 0){
var myLayer = selectedLayers[0];
}else{
alert("No layers selected.");
}

Thank you Dan!!
