Arrow data

Every arrow is an entry in the arrowplus/arrows datapack registry. A datapack can add new arrows, or change built-in ones by overwriting their file.

data/<namespace>/arrowplus/arrows/<name>.json

For example, data/mymod/arrowplus/arrows/ruby.json adds the arrow mymod:ruby. The mod's own arrows live in data/arrowplus/arrowplus/arrows/.

Arrow designer

Pick the stats and the colors, and copy the two files. The preview uses the mod's own textures, tinted the same way the game does it.

Fields

All fields are required, except stickData and featherData, which are only needed with custom sticks and feathers.

Field	Type	Description
material	item id, #tag or list	The top item of the recipe.
baseDamage	number	Damage on hit before enchantments. The vanilla Flint Arrow does 2.0.
color	int	Color of the arrow head, as a signed decimal ARGB int. -12532481 is #40C4FF. The designer above converts for you.
translationKey	string	Lang key for the arrow's name, e.g. item.mymod.ruby_arrow.
flame	boolean	Whether the arrow sets the target on fire.
gravity	number	How fast the arrow drops. Built-in arrows use 0.05; lower is flatter.
effects	object	Effects applied on hit, effect id → amplifier. {} for none.
feather	item id	The bottom item: minecraft:feather, or arrowplus:custom_feather with featherData.
featherData	feather id	Which custom feather, e.g. arrowplus:gilded. Needed with arrowplus:custom_feather.
stick	item id	The middle item: minecraft:stick, or arrowplus:custom_stick with stickData.
stickData	stick id	Which custom stick, e.g. arrowplus:copper. Needed with arrowplus:custom_stick.
outputAmount	int	Arrows per craft. The Fletching Table makes double.

stickData and featherData

If stick is arrowplus:custom_stick, the entry must have stickData. If feather is arrowplus:custom_feather, it must have featherData. Otherwise the datapack fails to load.
