Clear NPC Chatbox UI

Original Discord Post by petroslouca | 2024-10-01 20:45:04

Hello,

I am using the latest version of Convai SDK in Unity3D 2022.3.21f1 and I would like to clear the Chatbox dialogue text list completely.

There is a public function in ChatBoxUI.cs (attached to the Convai Transcript Canvas prefab that I am using), called ClearUI, see below, but calling it the dialogue is not cleared:

public void ClearUI()
{
foreach (Message message in _messageList) Destroy(message.TextObject.gameObject);
_messageList.Clear();
}

Could you please help me on that?

Also, is there a recommended way to disable the “thumbs up” icons/functionality in the chatbox completely?

Thank you!

Hi <@606256062613684224> sorry for late response can you try the following

 public void ClearUI()
        {
            for(int i = _messageList.Count - 1; i >= 0 ; i--){
            Destroy(messageList[i].TextObject.gameObject)
        }
            _messageList.Clear();
        }

Thank you K3! I modified the code in ChatBoxUI.cs script as follows based on <@433610960725344267>'s suggestion:

///


/// Clears all messages from the UI.
///
public void ClearUI()
{
//foreach (Message message in _messageList) Destroy(message.TextObject.gameObject);
//_messageList.Clear();

        // Convai Discord suggested custom code for clearing UI (PL)
        for (int i = _messageList.Count - 1; i >= 0; i--)
        {
            Destroy(_messageList[i].TextObject.gameObject);
        }
        _messageList.Clear();
    }

I am calling the function as follows:

//Clear ChatUI from all messages
GameObject.Find(“Convai Transcript Canvas(Clone)”).GetComponent().ClearUI();

But the chat box is not cleared, am I missing something?

ChatBoxUI chatBoxUI = FindGameObjectsByType<ChatBoxUI>();
chatBoxUI.ClearUI();

Unfortunately that did not work for me, I used the following function to iterate and destroy each chatbox message:

public void DestroyAllChatBoxUIMessages()
    {
        // Find the ChatBox's child GameObject "Content"
        GameObject chatBox = GameObject.Find("Content");

        if (chatBox != null)
        {
            // Loop through each child of the ChatBox
            foreach (Transform child in chatBox.transform)
            {
                // Check if the child's name is "ChatBox(Clone)"
                if (child.gameObject.name == "ChatBox(Clone)")
                {
                    // Destroy the child GameObject
                    Destroy(child.gameObject);
                }
            }

            Debug.Log("All ChatBox(Clone) gameobjects destroyed!");
        }
        else
        {
            Debug.LogWarning("ChatBox(Clone) GameObject not found.");
        }
    }

Is it working with this code?

Yes, each chatbox message under Content is destroyed, therefore clearing all UI messages.
