/**
 * 
 * When right-clicked, the hookshot shoots out up to 8 blocks away, grabbing on to a suitable
 * material and pulling the player to that position. There are multiple variations:
 * 
 * Hookshot: grapples wood
 * Stoneshot: grapples stone; if it hits wood, it will destroy the block
 * Multishot: can grapple wood, stone, clay, and ground (but not sand)
 * Extended (add-on): doubles the reach distance
 * 
 * Note that all variations will break glass upon impact.
 * 
 * Only the first type (Hookshot) can be found; the others must be built from this base hookshot
 * by finding components and getting help from villagers.
