[Question]Saving/Loading data to xml file

kieran · October 8, 2017

I have been messing with a login panel I found on the community, made my own GUI since the one it had didn't center.

The problem is, the text from the edit box's won't save to xml file, here is what I have.

Thanks for help, looked over code and it all looks like the working resource.

WorthlessCynomys · October 8, 2017

Did the resource work with the original GUI?

You can see that a tab panel is used originally, which is not that nice on a login panel... And also there are error messages if you put wrong name/password in which I removed.

So I found a problem. When you trigger the onRequestLogin, you send the localPlayer, the username and the password but the server side needs the username, the password and the checkbox state. Basically it handles username as the player element, password as the username and checkbox state as the password.

My hero thanks, can't believe I missed that.
