blocking send text - chat C# script

I think is a common error make by users, but I don't know what is wrong :
I make a GameManager with a default text prefab.
The script work well with focus on enter and add text when I press the space key.
After the chatBox.isFocused is focus all text is block and is not add to the text area : textObject.
The script is this :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class GameManager : MonoBehaviour {
7.     public int maxMessages = 25;
8.     public string username;
9.     public GameObject chatPanel, textObject;
10.     public InputField chatBox;
11.  
12.     public Color playerMessage, info;
13.  
14.     [SerializeField]
15.     List<Message> messageList = new List<Message>();
16.     // Use this for initialization
17.     void Start () {
18.        
19.     }
20.  
21.     // Update is called once per frame
22.     void Update()
23.     {
24.  
25.         if (!chatBox.isFocused)
26.         {
27.  
28.             if (Input.GetKeyDown(KeyCode.Space))
29.             {
30.                 SendMessageToChat("You peressed the space key !", Message.MessageType.info);
31.                 Debug.Log("Space");
32.             }
33.             if (Input.GetKeyDown(KeyCode.Return))
34.             {
35.                 chatBox.ActivateInputField();
36.             }
37.         }
38.         else
39.         {
40.                 if (Input.GetKeyDown(KeyCode.Return) && chatBox.text != "")
41.                 {
42.                     SendMessageToChat(username + "| " + chatBox.text, Message.MessageType.playerMessage);
43.                     chatBox.text = "";
44.                 }
45.         }
46.     }
47.  
48.     public void SendMessageToChat(string text, Message.MessageType messageType)
49.     {
50.         if (messageList.Count >= maxMessages)
51.         {
52.             Destroy(messageList[0].textObject.gameObject);
53.             messageList.Remove(messageList[0]);
54.         }
55.         Message newMessage = new Message();
56.         newMessage.text = text;
57.         GameObject newText = Instantiate(textObject, chatPanel.transform);
58.         newMessage.textObject = newText.GetComponent<Text>();
59.         newMessage.textObject.text = newMessage.text;
60.         newMessage.textObject.color = MessageTypeColor(messageType);
61.         messageList.Add(newMessage);
62. }
63.  
64.     Color MessageTypeColor(Message.MessageType messageType) {
65.         Color color = info;
66.         switch (messageType) {
67.             case Message.MessageType.playerMessage:
68.                 color = playerMessage;
69.                 break;
70.  
71.         }
72.         return color;
73.     }
74. }
75.  
76. [System.Serializable]
77. public class Message
78. {
79.     public string text;
80.     public Text textObject;
81.     public MessageType messsageType;
82.     public enum MessageType
83.     {
84.         playerMessage,
85.         info
86.     }
87. }

 

Sorry, I didn't understand your comment/question. Could you try rephrasing it?

 

the problem with this code is from knitting code under Update ...

 

I solve the issue.

 

May I know the solution?
