Minecraft Explosion Calculator

Calculate protected explosion damage, then run a reproducible 1,352-ray blast through ten interactive Minecraft structures.

Quick answer

How the Explosion Calculator Works

Select an explosion source, player protection, terrain, and structure. The result combines verified entity damage with an orbitable seeded block-destruction simulation.

Ten structures on five terrain presets
Vanilla-style 1,352-ray seeded destruction
Orbitable 3D replay and block diagnostic

How to Use the Minecraft Explosion Calculator

Choose an explosion source or custom power and enter the player protection values.
Select one of five terrains, one of ten structures, and a simulation seed.
Calculate, orbit the surviving structure, or replay blocks being removed in blast order.

Important Minecraft Mechanics

Damage falls with normalized distance and line-of-sight exposure; points outside twice the explosion power receive no blast damage.

TNT minecart strength can vary with velocity, unlike fixed-strength TNT.

Explosion Calculator FAQs

Why does exposure change the result?

Blocks between the explosion and the entity reduce the sampled line of sight, lowering blast impact.

Is the structure result repeatable?

Yes. The same structure, source power, and seed cast the same 1,352 rays and produce the same surviving blocks.

Evidence states are intentionally conservative. Automated software checks and in-game verification are reported separately.
