Version 3.2.3
++++++++++++++++++++++++++ NETLock +++++++++++++++++++++++++++
=Social Media/Contact Inforamtion & Orginal Github link!=
- Check out orginal code at https://github.com/XeCrash/NETLock
- Twitter: @XeCrashDev
- Discord: Bitwise#1337
THIS UPDATE: (+ = added | - = removed | x = bug fix's)
x - Fixed a bug where, if you had maintenance mode and free mode activated at the same time you could still login.
TODO:
- Refactor Messy Code. It's pretty messy but it works!
- Work out bugs as they come into light.
HELP:
- If you want to look at the example application that would be the best way to figure it out!
- I'll be making a tutorial video on how to set it up Version 3.2.3 soon!
COMING SOON:
- Account level system. (1 - 7) (Not yet added this update)
- Feel free to message me some ideas for next update (TIP: I'm most active on Discord)
