Macro javascript problem

[AGreen]

Hi dRowAudio (or any one else), I wonder if you can tell me why javascript such as the following doesn't work. To me it looks ok but the editor won't accept it. Does the getProperty method only work in certain circumstances?

Code: Select all

var tracks = Tracktion.getSelectedEditElements ('track');
var track = tracks[0];
if (track.getProperty ('name') == 'Guitar')
	Tracktion.showMessage ('Guitar');

Also, how would I go about getting a list of all plugins on a track and is it possible to select a track without selecting another object like a plugin or clip first.

okay first I wish I could help with Macro's issue but I only know how to do the basic things like load up plugins, but yes you can select tracks only and your plugins can't be viewed by track but in the cpu tab you can see a list of every plugin in the edit there is a option to group by track but it will only show the track name, cpu and latency sum for that whole track and you can select it and select the option show selection in edit and this will select the track only also. You can select a track with a Midi controler, macro, or mouse by clicking on the track on the left side of the track were the track name is located after selecting any track or plugin you can now navigate by holding alt and pressing the arrow keys to move up and down the tracks and also go up an down left and right from track to track selecting plugins once you select a plugin I hope this helps.

Puzzled here. I couldn't get

if (track.getProperty ('name') == 'Guitar')

accepted. It did accept

if (track.getName == 'Guitar')

but the value of track.getName was always "undefined".

Thanks lay it, but I'm trying to select tracks by macro.

Yes jabe, there seem to be some funny things going on. Some statements will work in a for loop but not as a single line which is very odd. The getProperty statement seems to be an example of that. We really need a list of methods and their usage because otherwise we're working blind. The following works by the way:

Code: Select all

var tracks = Tracktion.getSelectedEditElements ('track');

for (var i = 0; i < tracks.length; i++){
	var track = tracks[i];
    if (track.getProperty ('name') == 'Guitar')
		Tracktion.showMessage ('Guitar');
}

The Tracktion.showMessage() bit isn't showing a message here, unless I'm looking in the wrong place.

It should show up next to the mouse if the track is named "Guitar" and it's selected.

I can confirm this is a bug. I think it's a parse error (which stems from the fact that the script is parsed when typed slightly differently to when it's actually run as obviously there won't be any selected tracks or objects returned so we have to create dummy objects with the various methods on them e.g. the getProperty/setProperty methods).

I think what's happening is that getSelectedEditElements is supposed to return an array but when parsed it's actually returning just a single dummy object. I'm not sure exactly why using it in a loop works though, it might just be that the parser can't keep up or the call to .length is actually turning it in to an array.

I think I've got a fix for this now though so will do some tests and hopefully the fix will make it in to 8.1.1.

Ok dRow thanks for that. I'll just use the for loop work around for now.

I put that line on its own in a macro and caught the bubble with it in. Thanks.
