I have lots of events need to be moved into different buses or routing groups, but i can’t find a way to do this from Javascript.
Please help me!!! Thank you so much!

Hi,
Using the `.dump()` ([FMOD Studio | Scripting API Reference - ManagedRelationship.dump](https://fmod.com/docs/2.02/studio/scripting-api-reference-project-managedobject.html#managedrelationshipdump)) function on an event in the Mixer window ([FMOD Studio | Mixing - Anotomy of the Mixer](https://fmod.com/docs/2.02/studio/mixing.html#anatomy-of-the-mixer)) you can see its output is set to `output: (ManagedObject:MixerMaster)` which is what we want to change.
I have created a script which will assign a selection of events to a chosen group:
> **Example script**
>
> ```auto
> // Adding menu option
> studio.menu.addMenuItem({
> name: "Set Group",
> execute: function() {setGroup();}
> })
>
> function setGroup() {
> var busPath = studio.system.getText("Group Path", "path");
> var bus = studio.project.lookup(busPath);
>
> if (bus == null) {
> alert("Invalid bus path");
> return;
> }
>
> var events = studio.window.browserSelection();
>
> if (events.length == 0) {
> alert("Failed to find events");
> return;
> }
>
> for (i = 0; i < events.length; i++) {
> if (events[i] == null) {
> alert("Event invalid");
> return;
> }
> else {
> events[i].output = bus;
> }
> }
>
> alert("Assigned group");
> }
>
> ```
hope this helps!

Sorry, it seems that this cannot work, it still stays in the previous bus, not the bus i want to assigned. When i dump an event which is assigned to a bank already, i cannot see a output property, For example:
```auto
(ManagedObject:Event):
id: "{bc929a1e-6a19-40c5-bf15-130fd12264fc}",
entity: "Event",
isValid: true,
relationships: (ManagedRelationshipMap:Event),
properties: (ManagedPropertyMap:Event),
isOfType: ,
isOfExactType: ,
nullify: ,
name: "BGM_Room",
isDefault: false,
note: undefined,
outputFormat: 1,
uiMarkerTracksVisible: true,
uiMaxMarkerTracksVisible: 8,
selectables: [],
folder: (ManagedObject:EventFolder),
items: [],
uiLastParameterSelection: (ManagedObject:Timeline),
mixer: (ManagedObject:EventMixer),
masterTrack: (ManagedObject:MasterTrack),
mixerInput: (ManagedObject:MixerInput),
automatableProperties: (ManagedObject:EventAutomatableProperties),
markerTracks: [(ManagedObject:MarkerTrack)],
groupTracks: [(ManagedObject:GroupTrack)],
returnTracks: [],
timeline: (ManagedObject:Timeline),
parameters: [(ManagedObject:ParameterProxy)],
tags: [],
userProperties: [],
references: [],
banks: [(ManagedObject:Bank)],
defaultEvent: null,
clonedEvents: [],
isPlaying: ,
isPaused: ,
isStopping: ,
isRecording: ,
play: ,
togglePause: ,
stopImmediate: ,
stopNonImmediate: ,
returnToStart: ,
keyOff: ,
toggleRecording: ,
getPath: ,
get3DAttributes: ,
set3DAttributes: ,
getCursorPosition: ,
setCursorPosition: ,
getPlayheadPosition: ,
getParameterPresets: ,
addGameParameter: ,
addGroupTrack: ,
addReturnTrack: ,
addMarkerTrack: ,
addTagToEvent: ,
getItem: ,
dump: ,
document: ,
```
But I found another way to achieve this! Thank you very much!!!

I should have mentioned you need to have the mixer window open for the script to work. Good to hear you found an alternative solution.
