This gold farm allows you to fully automate gold production or semi-automatic XP and gold collection in your Minecraft overworld, and can also be fully activated and deactivated!
With this gold farm you can farm gold directly in your overworld for e.g. drive rails, gold apples/carrots or beacons. This can be done fully automatically, quasi "on the side", or semi-automatically, whereby the semi-automatic variant also serves as an XP farm and, depending on the looting enchantment on the sword, also brings higher yields.
This farm is based on the spawn behavior of pig zombies (ZombiePigmen). These are the only infinite gold source available in Minecraft and spawn in activated nether portals. In order to achieve the highest possible spawn rate and to use the obsidian as effectively as possible, the largest possible portals should be used (up to 21×21 blocks large portals with 23×23 blocks obsidian frame possible!).
When crossing open trapdoors between portals, the pig zombies fall from the obsidian frames and can be collected and transported to the farm chamber by customizable water streams.
Once there, you can either farm for gold and XP manually (significantly increased gold yield through Loot I-III enchantments!) or activate the fully automatic farming process, which drowns the pig zombies in a simple water trap.
To activate and deactivate the farm or the portals, you need a redstone switch on the side, which is explained below and is very simple in its basic structure!
Of course, obtaining the obsidian in Survival Mode at the beginning of the game is not easy and tedious, but this farm can be adjusted in its size to your respective possibilities and game progress ideally!
