Hi, I’d like to get a reference to the master bank at runtime and retrieve a list of all events (for a sound test menu feature).
I’m not clear on exactly how you are suppose to retrieve a reference to the master bank in Unity in order to then use `bank.getEventList()`.

Can someone point me in the right direction? Thank you!

You can try something like this:
```auto
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class loadBanksScript : MonoBehaviour
{
[FMODUnity.BankRef]
public string bankPath;
FMOD.Studio.Bank bank;
FMOD.Studio.EventDescription[] eventDescriptions;
// Start is called before the first frame update
void Start()
{
FMODUnity.RuntimeManager.StudioSystem.loadBankFile(bankPath, FMOD.Studio.LOAD_BANK_FLAGS.NORMAL, out bank);
bank.getEventList(out eventDescriptions);
foreach (FMOD.Studio.EventDescription eventDesc in eventDescriptions)
{
eventDesc.getPath(out string eventPath);
Debug.Log(eventPath);
}
}
// Update is called once per frame
void Update()
{
}
}
```
Please keep in mind that the Master bank does not contain all the events in the FMOD Studio project, only the events that have been assigned to it. You can only get the list of events assigned to a particular bank. Instead, ensuring the Master bank and the Master.strings bank have been loaded, you will need to `getEventList` on every bank loaded into Unity to get a list of all events.

Thank you for the sample code. I attempted to run this using both `Master` and `Master.strings` when selecting the `bankPath` in the Unity Editor. When I run the game I get the following error:
```auto
[FMOD] FMOD_OS_File_Open : fopen failed to open 'Master', errno = 2
UnityEngine.Debug:LogError (object)
FMODUnity.RuntimeUtils:DebugLogError (string) (at Assets/Plugins/FMOD/src/RuntimeUtils.cs:549)
FMODUnity.RuntimeManager:DEBUG_CALLBACK (FMOD.DEBUG_FLAGS,intptr,int,intptr,intptr) (at Assets/Plugins/FMOD/src/RuntimeManager.cs:82)
```
and the error
```auto
[FMOD] RuntimeBankModel::openFile : Failed to open file 'Master'
UnityEngine.Debug:LogError (object)
FMODUnity.RuntimeUtils:DebugLogError (string) (at Assets/Plugins/FMOD/src/RuntimeUtils.cs:549)
FMODUnity.RuntimeManager:DEBUG_CALLBACK (FMOD.DEBUG_FLAGS,intptr,int,intptr,intptr) (at Assets/Plugins/FMOD/src/RuntimeManager.cs:82)
```
For reference I currently have the FMOD settings configured to:
Source Type: Multiple Platform Build
Import Type: Streaming Assets
Load Banks: All
Thanks again for your help!

My mistake - it seems that `FMODUnity.RuntimeManager.StudioSystem.loadBankFile()` requires the full bank path which `[FMODUnity.BankRef]` does not provide. `RuntimeManager.LoadBank()` does work with `[FMODUnity.BankRef]` but does not provide the loaded bank back as a variable.
There is also an issue we’ve discovered which is banks don’t get copied over to `StreamingAssets` until build time, which makes it incompatible with trying to pass the bank’s full path when using the Unity PIE mode. This has been raised and will be looked at for a future release.
In the meantime, please use this instead - it checks if the game is playing in the editor or in a built game:
```cs
using System.Collections;
using System.IO;
using System.Collections.Generic;
using UnityEngine;
public class loadBankScript : MonoBehaviour
{
[FMODUnity.BankRef]
public string bankPath;
public FMODUnity.EventReference eventPath;
FMOD.Studio.Bank bank;
FMOD.Studio.EventDescription[] eventDescriptions;
// Start is called before the first frame update
void Start()
{
#if UNITY_EDITOR
FMODUnity.RuntimeManager.StudioSystem.loadBankFile("hard coded path to project's /Build/Desktop/" + bankPath + ".bank", FMOD.Studio.LOAD_BANK_FLAGS.NORMAL, out bank);
#endif
#if !UNITY_EDITOR
FMODUnity.RuntimeManager.StudioSystem.loadBankFile(Path.Combine(Application.streamingAssetsPath, "Desktop/" + bankPath + ".bank"), FMOD.Studio.LOAD_BANK_FLAGS.NORMAL, out bank);
if (Directory.Exists(Application.streamingAssetsPath))
{
string worldsFolder = Application.streamingAssetsPath;
DirectoryInfo d = new DirectoryInfo(worldsFolder);
foreach (var file in d.GetFiles())
{
Debug.Log(file);
}
}
else
{
Debug.Log("No streaming assets folder");
}
#endif
//FMODUnity.RuntimeManager.LoadBank(Application.streamingAssetsPath + "/" + bankPath + ".bank");
bank.getEventList(out eventDescriptions);
foreach (FMOD.Studio.EventDescription eventDesc in eventDescriptions)
{
eventDesc.getPath(out string eventPath);
Debug.Log(eventPath);
}
}
// Update is called once per frame
void Update()
{
}
}
```
Be sure to change the hard coded path to where your FMOD Studio project’s build folder is.

Ok, we are making progress.
When I run this code (making appropriate adjustments), I am able to get the bank.
However, when I attempt to call `bank.getEventList(out eventDescriptions)` the output array is always null, and I get the error code `Invalid Handle`. To check, I tried calling `bank.hasHandle()` which appears to always be returning false.
Is there perhaps another step I am missing?
Thanks again for your help in figuring this out. For reference here is the adjusted code I am calling:
```auto
[FMODUnity.BankRef][SerializeField] private string bankPath;
private void Start() {
string fullPath = System.IO.Path.Combine(Application.streamingAssetsPath, "Desktop/" + bankPath + ".bank");
#if UNITY_EDITOR
fullPath = Application.dataPath + "/FMODBuild/Desktop/" + bankPath + ".bank";
#endif
FMODUnity.RuntimeManager.StudioSystem.loadBankFile(fullPath, FMOD.Studio.LOAD_BANK_FLAGS.NORMAL, out FMOD.Studio.Bank bank);
Debug.Log(bank.hasHandle()); // Returns false
bank.getEventList(out FMOD.Studio.EventDescription[] eventDescriptions);
foreach(FMOD.Studio.EventDescription eventDesc in eventDescriptions) {
eventDesc.getPath(out string path);
Debug.Log(path);
}
}
```

I’m not able to replicate this issue. Copying your code and copying the built banks to the “FMODBuild” folder in the Unity project directory allows me to get the bank and it’s event list. Could you please verify that the banks are _not_ set to AssetBundle pointing to an FMODBuild folder. This setup places byte files in that folder and not bank files.

The banks are indeed _not_ set to AssetBundles.
I’m using unity 2022.1.0b16, and FMOD Integration 2.02.04.
I tried calling `bank.getLoadingState()` as well, which returns `UNLOADED` which seems odd to me.
I am able to hear all sounds running correctly, but for some reason this can’t seem to access the bank.
Any other suggestions? Thanks again.

I’m getting the feeling this bank is being loaded somewhere else and when you try to load it again from your script it is being ignored, therefore always returning `UNLOADED`.
You can get what banks are already loaded using `FMOD.Studio.System.getBanksList()`.

Excellent yes that was the issue. The bank I’m trying to load is the master bank, which is set to load by default. It is a bit counterintuitive that `bank.getLoadingState()` will return `UNLOADED` if the bank is already loaded… but I changed the code around to the snippet below and I am able to successfully read all event paths in the bank.
Thanks for your help!
```auto
[FMODUnity.BankRef][SerializeField] private string bankPath;
private void Start() {
FMODUnity.RuntimeManager.StudioSystem.getBankList(out FMOD.Studio.Bank[] loadedBanks);
foreach(FMOD.Studio.Bank bank in loadedBanks) {
bank.getPath(out string path);
if(path != bankPath) {
return;
}
bank.getEventList(out FMOD.Studio.EventDescription[] eventDescriptions);
foreach(FMOD.Studio.EventDescription eventDesc in eventDescriptions) {
eventDesc.getPath(out string eventPath);
Debug.Log(eventPath);
}
}
}
```
