The plugin is fine; its simple but could work for quick situations. I recommend some improvements in detections, and there are things you could manage better. But overall, its good, congratulations!
After reading the plugin source code, I conclude that GuardianAC is a poorly written plugin, the author is designing a nonsensical and flawed architecture, inheriting from nonsensical classes. Most of the values are hardcoded and cannot be changed, most of the detections are wrong => The whole thing is an unoptimized and leaky plugin that can be easily bypassed.
Hello. Large plugins such as anti-cheat should not use bukkit events to process player packets. Alternatively, you can try refactoring it on the PacketEventsAPI (it's the best right now). Bukkit events uses rather primitive methods of working with packets, which have long been bypassed even by the simplest cheat clients. And with the API mentioned above, you can expand the range of your capabilities.
Thanks for review, ok i will try to make plugin better
Version: 1.5.3
Good plugin, working as excepted. Daily updates are very good and report all false reviewing accounts. The author is making is dream. And this plugin is on start.
do you think that your bakkit events, which are bypass with any cheat, will somehow help and are you ready to make a premium version? don't be ashamed and dare on YouTube how anti-cheats do
