Description

Minecraft, but every block you break doubles everything around you.

Every time you break a block, everything around you doubles. Not just the drops: every item on the ground, every XP orb, every mob, every villager, every arrow in flight, every boat, the zombie that was creeping up behind you, the ender pearl you just threw, and yes, the Ender Dragon.

Break five blocks next to one pig and you have 32 pigs. Break five next to one zombie and you have a problem. Break a block in the End and there are two dragons. Break another and there are four.

The copies are exact: same gear, same health, same enchantments, same target (you). The action bar keeps score:

×2 126 items on the ground • 28 XP • 16 more of everything else

Only players are exempt.

How it works

The rule: every block a player breaks doubles every non-player entity within 24 blocks of it. The block's own drop lands first, so it doubles too: 1, 3, 7, 15, 31 cobblestone after five breaks.
Exact copies: clones keep their gear, health, enchantments and stack size, but get a new identity.
It breaks, but slowly: doubling is exponential, so two lag valves hold back only the entity count, never the numbers:
- Past 400 item entities in range, piles grow in place instead of spawning more. One pile can hold 16,777,216 items, and it survives saving and reloading the world.
- Past 120 creatures in range, mobs stop doubling.
Measured: 20 stacks of iron doubled eight times is 327,680 ingots on the ground in 364 entities, and the worst server tick was 8 ms.
Want a triple run? Set multiplier = 3 and it becomes Everything Triples.

Config

Edit config/everythingdoubles.properties, then run /everythingdoubles config reload. Ops can also change any option in game with /everythingdoubles config <option> <value>, or see everything with /everythingdoubles config.

Option	Default	What it does
`enabled`	`true`	Master switch (handy between takes)
`multiplier`	`2`	How many of everything after each break (2 to 10). 3 = Everything Triples
`multiplyItems`	`true`	Multiply dropped items
`multiplyXp`	`true`	Multiply XP orbs
`multiplyMobs`	`true`	Multiply mobs, arrows, boats, the dragon and everything else that isn't a player. `false` gives a "Drops Double" run
`radius`	`24`	Reach around the broken block, in blocks
`maxItemEntities`	`400`	Lag valve: past this many item entities, piles grow in place
`maxMobs`	`120`	Lag valve: past this many creatures, mobs stop multiplying
`workInCreative`	`true`	Also trigger on creative-mode breaks
`actionBar`	`true`	Show the running tally on the action bar
