Hi, I have a weird problem that only happens once I’ve built my project. I have been working on this issue for a couple of days and I can’t seem to find anything similar anywhere else on the internet. My code works exactly the way I want it to in the unity editor however things go astray when I build my project.
In the ContactsList scene I have a list of buttons that are automatically generated on start. Each button has a text object, which is set to the contact’s name, and an image object, which is set to the contact’s avatar. Up to this point everything works fine in the build. The names are generated correctly and the sprites appear fine.
When you click on one of the buttons you are taken to the Messenger scene where you can message a contact. In the messenger scene the contact’s avatar image and name are displayed. The name and the image should match the corresponding information on the button you clicked. The avatar image passes through correctly and matches the image on the button.
However the contact name does not pass through correctly. Instead of setting the name to the contact button name, it sets it to the original name of the button prefab’s text component. I know this because I have tried changing the button prefab’s name text and it always matches the name set in the Messenger scene.
What my code also does is store a text file of messages. The text file’s name consists of the name of the contact, which is extracted from the avatar game object in the messenger screen. This avatar object is also a prefab and I have checked what the text file is called under the _data folder in my build folder and it comes out as the original avatar prefab’s name rather than the one I set at runtime using script.
Because of these two things I believe that my game is passing text from the original prefabs rather than the values assigned to the instantiated prefabs during runtime. However strangely this is only happening when I have built the project and is only happening to text components attached to prefabs and not for example Image components, which work fine.
I have tried using PlayerPrefs to pass the name variables between scenes instead and I get the same problem either way. It’s been a bit tricky to debug as the problem only occurs once I’ve built my project. Any ideas as to what might be going on would be appreciated, thank you.
Note: Here CustomiseMessengerInfo.contactName is being set to the button’s original prefab text, not the actual text.
/*
* LoadMessenger is attached to a button and passes the contact's name and avatar to the CustomiseMessengerInfo script
* It then loads the messenger scene
*/
public class LoadMessenger : MonoBehaviour
{
public TextMeshProUGUI contact;
public Image contactAvatar;
public void LoadMessengerScreen()
{
//this is getting original prefab text not actual text but don't know why
CustomiseMessengerInfo.contactName = contact.text.ToString();
CustomiseMessengerInfo.avatar = contactAvatar.sprite;
//get list of message objects and populate list view content with them
SceneManager.LoadScene("Messenger");
}
}
/*
* CustomiseMessengerInfo customises the components of a messenger scene to a specific person
*/
public class CustomiseMessengerInfo : MonoBehaviour
{
public static string contactName;
public static string contactBio;
public static Sprite avatar;
public GameObject placeholderAvatar;
public TextMeshProUGUI placeholderName;
// Start is called before the first frame update
void Start()
{
SetAvatarInfo();
}
public void SetAvatarInfo() {
placeholderAvatar.GetComponent<Image>().sprite = avatar;
placeholderName.SetText(contactName);
}
}
Note: All the logic in the SaveAndUpdateMessages class works ok, I’ve just included it because of this line: string localPath = Application.dataPath + “/”+ avatarName.text.ToString() + “MsgContainer.txt”; as avatarName.text.ToString() is also passing in the original prefab text, not the actual text.
/*
* I need in this class:
* A method that saves each message to a file containing messages
* The file will contain information in the format: messageContent | messageType \n
* Every time the messenger screen is loaded the file content will be loaded and processed into text to display in game objects
*/
public class SaveAndUpdateMessages : MonoBehaviour
{
GameObject msgContainer;//the content message container
public TextMeshProUGUI avatarName;//the avatar name
public GameObject received;//received text object
public GameObject sent;//sent text object
//Called when a message is posted
public void SaveMessageToFile(string messageContent, string messageType) {
string localPath = Application.dataPath + "/"+ avatarName.text.ToString() + "MsgContainer.txt";
if (!File.Exists(localPath)) {
File.Create(localPath).Dispose();
}
using (StreamWriter sw = File.AppendText(localPath))
{
sw.WriteLine(messageContent + "|" + messageType);
sw.Flush();
sw.Close();
}
}
//Called when the messenger screen is opened
public void LoadMessagesFromFile() {
string localPath = Application.dataPath + "/" + avatarName.text.ToString() + "MsgContainer.txt";
if (!File.Exists(localPath))
{
File.Create(localPath).Dispose();
return;
}
StreamReader inp_stm = new StreamReader(localPath);
while (!inp_stm.EndOfStream)
{
string inp_ln = inp_stm.ReadLine();
string[] message = inp_ln.Split('|');
if (message[1] == "Received")
{
gameObject.GetComponent<GenerateMessage>().CreateMessage(received,message[0]);
}
else
{
gameObject.GetComponent<GenerateMessage>().CreateMessage(sent, message[0]);
}
}
inp_stm.Close();
}
void Start()
{
LoadMessagesFromFile();
}
}
