Question

Reference item by ID

I'm working on a project where I need to be able to reference compositions by their unique ID attribute.

Is there a way to reference to an item in a project based on its ID without having to do a billion if check loops

to see if the ID matches?

Something similar to how you can reference layers by name.

app.project.activeItem.layer("playerItem")

Something like

ID = app.project.activeItem.id

app.project.items(ID)

would be ideal but that doesnt seem to work.

Once you find the composition in the loop, store it in a variable, then use that variable throughout the rest of your script.

I ended up creating a recursive function in order to locate the comp base on its id. Here's my final working function:

function findXmpComp(id){

    function digForComp(folder, id){

    var foundComp;

    var currentFolder = folder;

        for(var i=1; i<= currentFolder.items.length;i++){

            if(currentFolder.items.id == id){

                foundComp = currentFolder.items;

                return foundComp;

            }

            if(currentFolder.items.typeName == "Folder"){

                foundComp = digForComp(currentFolder.items, id);

            }

        }

        if(foundComp == null){

            return null;

        }else{

            return foundComp;

        }

    }

    var foundComp = digForComp(app.project, id)

    if(foundComp == null){

        alert("Missing Comp");

    }

    return foundComp;

}

Just curious... are you storing that comp id external to the project, i.e., that id would need to be the same between AE sessions? Or are you just using the id value within the same AE session?
