Not In Block Position Cache

The arc:not_in_block_pos_cache condition type checks if a block's position is not in the player's recent placement history. This is useful for preventing rewards from blocks that the player has placed themselves.

Parameters

This condition type does not have any parameters.

Example

The following example gives the player a diamond only when they break a naturally-occurring stone block, not one they placed.
