Minecraft, but It Rains TNT

Rain used to mean a wet walk home. Now it means incoming. While it is raining, primed TNT falls around every player on a shared timer: two sticks every seven seconds, scattered across twelve blocks, dropped from high enough that the fuse gives you a running start. Thunderstorms double the salvo and long storms slowly escalate. TNT only spawns where the sky above you is genuinely open, so a solid roof or a deep mineshaft really does protect you. The instant the rain stops, the bombardment stops with it.

Built for Java Edition 26.3 only. Older versions read loot tables, predicates and advancements in a different format, so they list the pack as made for a newer version, and it will not work there.

How it works

• A tick loop asks a weather_check predicate whether it is raining. Rain starting fires a title, a thunderclap and a boss bar; rain stopping tears the timer, the bar and the bombardment down on the same tick.
• Each volley runs execute as @a at @s, rolls an offset with /random value, and feeds it to a macro function that positions the summon relative to that player, so TNT lands around you rather than inside you.
• A shell only spawns if the block 14-20 above you is air. That one check is the entire shelter rule: solid roofs, cave ceilings and the build-height limit all silently absorb the drop instead of you.
• The rate is capped three ways at once: a shared cooldown between volleys, a hard limit on how much live TNT may exist in the world, and skips for creative, spectator, exempt and totem-shielded players.
• Thunderstorms double the sticks per player, and a storm that drags past two, four and six minutes shortens its own delay one second at a time, down to a configurable floor.
• Using a Totem of Undying trips a hidden advancement whose reward function revokes itself and grants 30 seconds of immunity, so the trigger re-arms for the next totem.
