Talk with me about any of my plugins or life in general on my discord!
A new Exploit has appeared!
A new item duplication glitch was popularized by TheSpiffingBrit in this youtube video. It involves using a Donkey with a chest in order to duplicate everything that the Donkey is holding. Obviously this poses a threat to the balance of survival and economy on servers everywhere.
This lightweight plugin aims to patch this exploit that has the power to break economies everywhere.
I got excited...
I put this together before realizing that Spigot had the foresight to patch this out at the server level, so now this plugin serves as a notifier when the exploit is attempted.
And then more Exploits!
I went from thinking I was blocking an exploit, to realizing I wasn't the one that fixed it, to now blocking yet another donkey-related dupe exploit. And yes, I checked, I am the one blocking it this time. Donkeys are buggy...
TO DO:
+ kill entities that would have died after teleportation for consistency?
- add player-specific detection of the newly blocked exploit
- add API for attempt based plugin interaction
- add config to allow commands to be executed automatically on detection
To Done!
+ add updater for rapid re-patching if bypasses are found
- added blocking of duplication using the End Portal (thanks to @actester1235 )
- add coverage of Llamas and Mules (thanks to @Neuter )
- make patch a bit less tossed together
- add accurate detection of attempts to use the exploit
