Hi!

I already have all my events but I want to turn them all into 3D events instead of 2D events. Can this be done through the Scripting API?

Thanks,

```auto
function AddSpatializer()
{
    _event.addEffect("SpatialiserEffect")
}

studio.menu.addMenuItem({
    name: "***\\Add Spatializer",
    isEnabled: function() { var _event = studio.window.browserCurrent(); return _event && _event.isOfExactType("Event"); },
    execute: function() { AddSpatializer(); }
});

```

Hi,

Yes! You can, it will be a lot easier to do it in FMOD Studio using [FMOD Studio | Bulk Editing Events](https://fmod.com/docs/2.02/studio/authoring-events.html#bulk-editing-events). Select all your `Events` in Studio and right-click on the Deck, where to find the Deck in the Studio is explained in the [Glossary](https://www.fmod.com/docs/2.01/studio/glossary.html#deck), then add `FMOD Spatializer`. The `Spatializer` should then be added to all selected `Events`.

To add Spatializers through scripting add this script to the FMOD Directory e.g. `C:\Program Files\FMOD SoundSystem\FMOD Studio 2.02.07\scripts`

> **Add Spatializer**
>
> ```auto
> // Adding menu option 
> studio.menu.addMenuItem({
> name: "Add Spatializer",
> execute: function() { AddSpatializer();},
> })
> 
> // Function to add Spatializers 
> function AddSpatializer() {
> // Retrieve an array of all the events in our project 
> var allEvents = studio.project.model.Event.findInstances();
> 
> for(var i=0; i < allEvents.length; i++) {
> // If the event already has a spatializer then skip it 
> if (allEvents[i].is3D() == true)
> continue; 
> else
> allEvents[i].masterTrack.mixerGroup.effectChain.addEffect("SpatialiserEffect");
> }
> // Print when it has run successfully 
> alert("Added Spatializer");
> }
> 
> ```

I hope this helps!
