Melon Guns - Only One Command

Hello! Today, I've made Melon Guns! They shoot melons! Epic!

Click here for the command!

Crafting:
Melon Gun - Melon Block + Bow
All recipes are floor crafting

Tutorial:
To shoot with a Melon Gun, right click. This will melons (not melon blocks, melon slices), so
your going to need a lot of melons if you want to use your gun alot. If you have no melons on
you, the gun will not shoot. Melons will do 2 hearts of damage, but this is constant, so 20 damage
per-second (don't know if ticks/second changed since 1.9)!
