On my server I've been having issues with mobs building up and either causing no more mobs to be spawned, or the server to lag in some cases. Are there any plugins already out there that will cause a mob to die/despawn after a certain amount of time to prevent them from piling up like this? All I've been able to find so far are hard caps to the amount of mobs being spawned. While a temporary solution, this approach would still run into problems where a player trying to make an XP grinder could ruin gameplay for the rest of the server due to all the mobs spawned. TLDR Version: Are there any plugins out there that cause Mobs to have a given lifetime, and after that lifetime is up they either die or despawn.
how do you want this to work? Do you want the entities to die after x amount of minutes after the server itself starts or when a chunk is entered? Maybe track the mobs when the player starts?
