Creating a game in Creative and then switching to Survival will disable achievements for the game.
Twelve stacks of cobblestone (768 total cobblestone) Eight buckets of water Four hoppers Four small chests
The cobblestone you use here should be placed at the height of the top of the walls that you built around the branches.
You can also use a fence for this step.
Eight blocks is the maximum distance that one block of water will travel over flat land before stopping.
When guarding the basement, make sure that you have a sword on you. This will ensure that you can kill any mobs which survive the fall.
This method isn’t viable in Survival Mode, and it won’t automatically spawn mobs; it’s best used for creating arena-style matches or traps.
One lever Three redstone dust One dispenser A stack (64) of your preferred mob spawn egg (you can add two or more stacks if you want to randomize your spawner)
At this point, you can test the lever by selecting it; if the redstone dust lights up when you select the lever, it’s working and you can turn it back off.
You can repeat this process to spawn another mob. If you have more than one type of mob spawn egg in the dispenser, the mob that spawns will be randomized.
