Problems adding text to UI Text Component

Question

I am building up a chat system for multiplayer, and am hitting a very strange wall that I can't explain.

My setup for this is a text field to enter text, and then a UI text object.

For the first message, everything is added to the text object perfectly, however after the first message is sent, or after a script rebuild, no text is added.

I know for certain through debugging that the message is being sent, and received correctly. I also know that the function that is supposed to add the text is also receiving the message correctly.

What's truly bizarre is if I test it offline, being I send the string from the text field straight to the text box, everything works perfectly.

I've also tried using the Concat method as well, same results (unsurprisingly). Full asset re-imports don't help either. The code responsible for adding the string is pretty straight forward:

 if (text.text.Length == 0)
     text.text += t;
 else
     text.text += "\n" + t;

"text" is a UI text.

Has anyone seen an issue like this before? Thanks!

Try to use this, the chat is the textbox, and inFi is the input field:

 if (inFi.text != "")
             {
                 chat.text += inFi.text;
                 chat.text += "\n";
                 inFi.text = "";
             }

Hope it works :D

This was solved a while ago, turns out the issue was very deep seeded in the way C# and C handle data types. I had used sizeof (which is a C macro), a few times to get the size of the strings. Because this was networked, there was some encoding involved that used a different data type for char than C understood, this created a massive amount of garbage characters.

Thank you for your answer, but I should close this question.
