Minecraft Java Edition – How to Disable Creepers’ Block Damage on a Minecraft Server

Minecraft isnt caching it in the traditional sense of the word, the data has to be stored in memory owned by minecraft at some point, in order for minecraft to do anything with the data. Even reading it!

Therefor it is not possible to totally disable 'caching'. Its also not possible for minecraft to just use the memory of the RAM disk directly, it has to go through the operating system first, which adds quite a bit of latency (nothing compared to HD access, but compared to RAM access).

So it's not useful to just disable caching, it might be possible to reduce the time until chunks that aren't near any players are unloaded with a plugin, but I have been unable to find one. One hackish way that might work is to reduce the maximum memory minecraft can use, that would force it to unload unused chunks faster.

Of course, the only wasted RAM is RAM that's not being used, so (on a dedicated machine) there is no harm in letting minecraft store something it can access very fast.

A list of things to help with creepers:

• Light up the outside yard to reduce the chance that a creeper can spawn and randomly walk into awareness range
• Always allow your entrances to have a clear view of the outside area so you can see what is there.
• Always use those clear views to check for creepers.
• When you leave your house, dash.. Get some good distance between you and the house. (While not directly a building thing, this is more of a consideration to make sure You can run some where :))
• Always -always- have more than one exit from a place. Preferably on different sides of the house/dwelling/whatever.
• Creepers can not blow up Obsidian blocks (but obsidian is a pain in the ass to build with)
• Creepers will still damage you but not blocks if they are in water, even in a stream of water seems to work with this.. However its quite a bit more of a pain in the ass than building in obsidian to build things with water covering all/most of it.
• Become that creepy person with tons of cats around.. But also be aware they will not halt/hinder/interrupt an already hissing creeper.

At the end of the day just putting up enough torches and making sure you can see whats around the doors is your best bet. There really is no way to make a house creeper proof. If it can get to where you are and you are next to your house, chances are it will blow up and take something with it.
