NimBlock

Two new conditions read the player at the time of the event: where they stand and what they hold.

• Player position (player.position) compares one coordinate of the player's feet (x, y or z, in blocks) with a value. Use y < 0 for a player below Y=0, including when the trigger does not provide their position, such as chat, join or command. Under block.break, {x}, {y} and {z} still describe the block.
• Item in the main hand (player.holding) checks the material the player currently holds. Use AIR for an empty hand. Invalid material names are rejected at runtime, as in the give-item action.
• The engine keeps no memory of its own. These are immediate reads: no counters, no blocks-broken totals, no distance-travelled totals, and no player data written by the engine.
• specVersion remains 1. Existing 1.1.x specs keep working. An older engine rejects a spec using either new condition as a whole, just as it rejects any unknown catalogue entry.
• The protection-diamant.json example uses the new checks in its pioche-en-main rule.
• Same Paper versions as 1.1.0 and the same Java 21 minimum.
