Runtime settings API

Reference for IConvaiRuntimeSettingsService — read current settings, apply patches, react to changes, and reset to defaults from code.

IConvaiRuntimeSettingsService is the scripting layer beneath the built-in Settings Panel. Any script can read the current settings snapshot, apply patches atomically, subscribe to change events, and control which transcript modes are exposed — without the panel being present in the scene.

Access the service through ConvaiManager:

ConvaiManager.ActiveManager.TryGetRuntimeSettingsService(out var settings);

IConvaiRuntimeSettingsService

Member	Type	Description
Current	ConvaiRuntimeSettingsSnapshot	Immutable snapshot of all current settings values
SupportedTranscriptModes	IReadOnlyCollection<ConvaiTranscriptMode>	Transcript modes currently registered as available for selection
Changed	event Action<ConvaiRuntimeSettingsChanged>	Fired whenever any setting changes
Apply(ConvaiRuntimeSettingsPatch patch)	ConvaiRuntimeSettingsApplyResult	Apply one or more settings atomically. Fields left null in the patch remain unchanged
ResetToDefaults()	ConvaiRuntimeSettingsApplyResult	Reset all settings to project defaults
SetSupportedTranscriptModes(IReadOnlyCollection<ConvaiTranscriptMode> modes)	void	Replace the set of transcript modes available for selection. Used to restrict the modes the Settings Panel dropdown exposes

ConvaiRuntimeSettingsSnapshot

An immutable struct returned by Current and included in apply results and change events. All fields reflect the state at the moment the snapshot was produced.

Field	Type	Description
PlayerDisplayName	string	Current player display name shown in transcript bubbles
TranscriptEnabled	bool	Whether transcript UI is enabled
NotificationsEnabled	bool	Whether in-scene notification popups are enabled
PreferredMicrophoneDeviceId	string	Device ID of the preferred microphone input
TranscriptMode	ConvaiTranscriptMode	Current transcript display mode (Chat or Subtitle)

ConvaiRuntimeSettingsPatch

Passed to Apply(). Any field left null remains unchanged after apply.

Field	Type	Description
PlayerDisplayName	string	Set a new player display name. null = no change
TranscriptEnabled	bool?	Enable or disable the transcript UI. null = no change
NotificationsEnabled	bool?	Enable or disable notifications. null = no change
PreferredMicrophoneDeviceId	string	Set preferred microphone device ID. null = no change
TranscriptMode	ConvaiTranscriptMode?	Switch transcript display mode. null = no change

ConvaiRuntimeSettingsApplyResult

Returned by Apply() and ResetToDefaults().

Field	Type	Description
Success	bool	true if the apply operation succeeded
Snapshot	ConvaiRuntimeSettingsSnapshot	Resulting settings state after the apply
AppliedMask	ConvaiRuntimeSettingsChangeMask	Bitmask of which fields actually changed
ValidationMessage	string	Reason for failure when Success == false. Empty on success

ConvaiRuntimeSettingsChanged

The payload delivered to Changed subscribers.

Field	Type	Description
Previous	ConvaiRuntimeSettingsSnapshot	Settings state before the change
Current	ConvaiRuntimeSettingsSnapshot	Settings state after the change
Mask	ConvaiRuntimeSettingsChangeMask	Bitmask indicating which fields changed

ConvaiRuntimeSettingsChangeMask

A [Flags] enum used in AppliedMask and ConvaiRuntimeSettingsChanged.Mask. Compare with bitwise AND to detect specific changes.

Value	Description
None	No fields changed
PlayerDisplayName	Player display name changed
TranscriptEnabled	Transcript enabled state changed
NotificationsEnabled	Notifications enabled state changed
PreferredMicrophoneDeviceId	Microphone selection changed
TranscriptMode	Transcript mode changed
All	All fields

Transcript mode limitation in the panel

The Transcript Style dropdown in the Settings Panel exposes only the modes registered in SupportedTranscriptModes. By default, SettingsPanelPresenter initializes this to { ConvaiTranscriptMode.Chat } only.

To expose additional modes in the panel dropdown, call SetSupportedTranscriptModes() before the panel opens:

if (ConvaiManager.ActiveManager.TryGetRuntimeSettingsService(out var settings))
{
    settings.SetSupportedTranscriptModes(new[]
    {
        ConvaiTranscriptMode.Chat,
        ConvaiTranscriptMode.Subtitle
    });
}

To switch to Subtitle mode bypassing the panel entirely, use Apply() directly:

settings.Apply(new ConvaiRuntimeSettingsPatch
{
    TranscriptMode = ConvaiTranscriptMode.Subtitle
});

See Chat and subtitle modes for full mode-switching details.

Usage examples

Read current settings

using Convai.Runtime.Components;
using Convai.Shared.Types;
using UnityEngine;

public class SettingsReader : MonoBehaviour
{
    private void Start()
    {
        if (ConvaiManager.ActiveManager.TryGetRuntimeSettingsService(out var settings))
        {
            ConvaiRuntimeSettingsSnapshot current = settings.Current;
            Debug.Log($"Player name: {current.PlayerDisplayName}");
            Debug.Log($"Transcript on: {current.TranscriptEnabled}");
            Debug.Log($"Mode: {current.TranscriptMode}");
        }
    }
}

Apply a settings patch

if (ConvaiManager.ActiveManager.TryGetRuntimeSettingsService(out var settings))
{
    var result = settings.Apply(new ConvaiRuntimeSettingsPatch
    {
        PlayerDisplayName = "Dr. Kaan",
        TranscriptEnabled = true,
        TranscriptMode = ConvaiTranscriptMode.Subtitle
    });

    if (!result.Success)
        Debug.LogWarning($"Settings apply failed: {result.ValidationMessage}");
}

React to settings changes

using Convai.Runtime.Components;
using Convai.Shared.Abstractions;
using Convai.Shared.Types;
using UnityEngine;

public class SettingsChangeReactor : MonoBehaviour
{
    private IConvaiRuntimeSettingsService _settings;

    private void OnEnable()
    {
        if (ConvaiManager.ActiveManager.TryGetRuntimeSettingsService(out _settings))
            _settings.Changed += OnSettingsChanged;
    }

    private void OnDisable()
    {
        if (_settings != null)
            _settings.Changed -= OnSettingsChanged;
    }

    private void OnSettingsChanged(ConvaiRuntimeSettingsChanged changed)
    {
        if ((changed.Mask & ConvaiRuntimeSettingsChangeMask.PreferredMicrophoneDeviceId) != 0)
        {
            Debug.Log($"Microphone changed to: {changed.Current.PreferredMicrophoneDeviceId}");
            ApplyMicrophoneChange(changed.Current.PreferredMicrophoneDeviceId);
        }

        if ((changed.Mask & ConvaiRuntimeSettingsChangeMask.PlayerDisplayName) != 0)
        {
            UpdatePlayerNameDisplay(changed.Current.PlayerDisplayName);
        }
    }
}

Analytics — track settings changes

A training platform logs when trainees change their microphone device for session quality analysis:

private void OnSettingsChanged(ConvaiRuntimeSettingsChanged changed)
{
    if ((changed.Mask & ConvaiRuntimeSettingsChangeMask.PreferredMicrophoneDeviceId) != 0)
    {
        AnalyticsTracker.LogEvent("microphone_changed", new Dictionary<string, object>
        {
            { "previous", changed.Previous.PreferredMicrophoneDeviceId },
            { "current", changed.Current.PreferredMicrophoneDeviceId }
        });
    }
}

Troubleshooting

Symptom	Likely cause	Fix
Apply() returns Success == false	Validation failure	Check result.ValidationMessage for the reason
Changed event not firing	Not subscribed, or subscribed after settings changed	Subscribe in OnEnable before the session starts
ResetToDefaults() result not checked	Return value ignored	ResetToDefaults() returns ConvaiRuntimeSettingsApplyResult — check result.Success if the reset must be verified
