< simpson>| * Projectiles. A little math has been done for them, but we largely don't have the entity-tracking infrastructure nor the trigonometry to actually implement throwing things.
There's code in packets for thrown potion, thrown xp bottle, and thrown enderpearl, but nothing about the others.
Either they don't work, or some plugin needs to be enabled and isn't documented in a way that shows up when grepping "throw" in the codebase.
