Check a render queue item exists or alert

[Filip Vandueren]

You could perhaps check for

app.project.renderQueue.numItems>0

Have you tried using renderQueue.numItems ?

Thanks guys, I’ve tried this but the problem is I’m still pretty new when it comes to the actual scripting syntax so i’m not 100% how to implement it. This is what I currently have:

var outputPath=app.project.renderQueue.item(1).outputModules[1].file.name.replace(/%20/g, “_”);

if(app.project.renderQueue.numItems>0)
{
alert(‘Add an output file!’);
}
else
{
output = app.project.activeItem.layers.addText(outputPath);
output.name = “

“;
output.transform.position.setValue([25,450]);
}

However, it doesn’t seem to be functioning correctly and I still just get the same error as before.

Any pointers would be great!

Thanks

John

You just need to rearrange things a little:

if(app.project.renderQueue.numItems>0)
{
var outputPath=app.project.renderQueue.item(1).outputModules[1].file.name.replace(/%20/g, “_”);
output = app.project.activeItem.layers.addText(outputPath);
output.name = “”;
output.transform.position.setValue([25,450]);
}
else
{
alert(‘Add an output file!’);
}

Thanks very much Dan. That works perfectly.

I’m very new to ae scripting so sometimes the syntax gets away from me. I’ve downloaded the AE Scripting Guide and now the ECMAScript Language Specification so hopefully these will help.

Thanks again

John
