TNT Expansion

Description

TNT Expansion adds 134 new TNTs to Minecraft 1.21.1 (NeoForge). Every one of them is a real TNT block: place it, light it with redstone, fire, flint and steel or a flaming arrow, mine it back, and chain it off other explosions. All that changes is what happens when the fuse runs out.

What is in it

• Multipliers — TNT x5, x10, x20, x50, x100, x250, x500, x1000, x5000, x10000.
• Nuclear — Nuclear, Atomic, Hydrogen and Tsar Bomb: a warhead actually falls out of the sky, detonates, throws up a mushroom cloud and leaves the ground glassed over with Radiation (a new status effect) lingering for minutes.
• From the sky — Meteor, Comet, Meteor Storm, Asteroid.
• Elements — Lava, Water, Ice, Snow, Blizzard, Fire, Napalm, Hellfire, Magma, Acid.
• Weather — Lightning, Thunder, Storm, Tornado and Earthquake (drag blocks and entities into a spiral), Tsunami (floods the area, then drains away), Volcano (raises a cone, throws burning rock, then collapses in on itself).
• Mobs — Creeper, Slime, Ghast, Blaze, Wither, Dragon, Zombie, Skeleton, Spider, Raid, Warden, Piglin, Guardian, Phantom, Shulker, Bees and more.
• Physics and space — Gravity, Anti-Gravity, Void, Black Hole, Time, Space, Dimension, Nether, End, Overworld, Portal, Teleport, Chunk.
• Building — House, Village, City, Castle, Island, Mountain, Planet.
• Digging — Drill, Quarry, Flatten, Excavator, Hollow.
• Riches — Gold, Diamond, Emerald, Iron, Redstone, Obsidian, Bedrock, Glass, Amethyst.
• End of the world — Apocalypse, BioHazard, Doomsday, Armageddon, Cataclysm, Extinction, World / Planet / Dimension Destroyer, Reality Breaker, The End of the World, The End of Everything, Ultimate, Infinity, God, Chaos (a different catastrophe every time) and Error 404 (deletes every block in every force-loaded chunk).

Textures

Made from the real vanilla TNT texture: only the colour of the sticks changes, plus the label, which carries either the number (X5, 100, 10K) or a symbol (nuclear, biohazard, skull, tornado, portal...). They sit next to vanilla blocks without looking out of place.

Crafting

Every TNT follows the same shape, so you learn the whole tree at once:

G I G      G = gunpowder
I P I      I = the themed ingredient (lava bucket, packed ice, nether star...)
G I G      P = the previous TNT in that family, or plain vanilla TNT

The chain is linear, not exponential, so even the last TNT is reachable in survival.

Performance

The big explosions do not use the vanilla system, which is impossible at a 190 block radius. A custom engine writes straight into the chunks, spreads the work across ticks under a block budget and resends the chunks to players, so the biggest crater in the mod carves itself out in front of you over a few seconds instead of freezing the server.

Configuration

config/tntexpansion-common.toml lets you cap the maximum radius, lower the work per tick, scale every explosion at once, or turn block damage off entirely.
