Pommel - Held Item Models

Additions:

• New predicate: is_using predicate will change the item model when you hold the use/right click with any item
• is_using has an "interpolation" of ~1sec to swap to other item models over time as it changes back to the normal model when the player stops using said item
• Thrown projectiles (eggs, snowballs, enderpearls, etc.) all use a new predicate: is_thrown
• New predicate: is_submerged when the player is under minecraft:water (doesn't work with other liquids)
  • When an item entity is thrown into water but then is no longer in water (i.e. you remove the water) the item still stays in it's "submerged" state
• is_using and is_submerged also change the item model in the gui

Changes:

• Villagers, Pandas, and Witches all now use the is_held predicate instead of is_ground
  • Note that these entities will still also take the display settings of the Ground display settings for said model. If need be, you can change the Ground display rotation, translation, scale to make items look better when held in these entity's hands.
• is_ground no longer changes the item model for thrown projectiles

Known Issues:

• is_using - Using an item and quickly switching to another may change the item model for a couple ticks for the client player.
