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.

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.
