Q&A for How to Defend Your House in Minecraft

If you would like to play Minecraft on a PC, there is a wikiHow page on it here .

The best way to burn mobs would be lava or fire along netherrack. If you want to get fancy, you could set up a dispenser with fire arrows that would go off at them when they stepped on a pressure plate but that is much more difficult.

Iron Golems will automatically attack all types of undead mob (except zombie/skeleton horses), as well as slimes, spiders, pillagers, witches, piglins, endermen, The Enderdragon (will attempt if within range), vexes (will attempt if within range), silverfish, magma cubes, endermites, guardians, blazes, and shulkers.

It is possible with commands or having walls on both sides and sticky pistons holding the blocks and a button/lever to change it.
