For 1.14:

If you are getting errors on launch saying "no such method" or something similar, you likely need to install kottle.

This mod now requires kottle to run, however the game can NOT detect if kottle is installed.

If you DO have kottle installed but you are still getting an error, please report it as a bug here.

To use a yoyo, right click it and it will throw out. While out, the yoyo will follow where you look and do damage to anything it touches. Right click again to pull it back in.

If you get too far away from a yoyo, you will be pulled towards it.

Crafting

Yoyos need 4 of the desired material, a stick, and a chord to craft a yoyo.

The cords are crafted with 8 string in a circle.

The Shear Yoyo

By combining an iron yoyo with shears, you can give the functionality of shears to your toy-weapon. It allows for the yoyo to cut grass and flowers and plants and stuff and to shear sheep and mooshrooms without damaging them.

The Yohoe

If putting shears on a yoyo made it work like shears, there's no reason putting a hoe on it wouldn't work, right? The Yohoe can harvest crops and replant them, while also tilling any soil that passes underneath it.

The Sticky Yoyo

At the cost of damage, you can combine a diamond yoyo with some sticky slimeballs to allow your toy to stick to blocks. Could be useful for getting around, considering you can reel yourself in and out from the yoyo once it's stuck.

Enchanting

Yoyos can be enchanted just like any weapon. They can have Sharpness, Looting, Unbreaking, etc.

In addition to the vanilla enchantments, yoyos can be enchanted with collecting. Collecting allows yoyos to pick up items, and the number of items it can pick up depends on the level of the enchantment.

Tinkers'

Yoyos and You

I've included an in-game guide book for everything tinkers' yoyos. It has information about all of the modifiers, as well as stats for every material you can use to craft your yoyos.

If you want to have a read, you just need to combine your trusty Materials and You with a yoyo cord.

Building the yoyo

The yoyo is made in the tool forge using an axle, two bodies, and a cord.

The different parts are crafted as usual in a part builder or by casting.

Parts

The cord determines how far away from you the yoyo gets.

The bodies determine the damage and movement speed.

The axle has a durability multiplier.

Both the cord and axle have friction, which determines how long the yoyo can stay out.

Botania

Yoyos can be made with materials from Botania, and have abilities appropriate for each tier.

First, of course, you need to make some cord out of manastring.

The Manasteel Yoyo

Behaves similarly to a shear yoyo, cutting down shrubs and leaves and such.

The Elementium Yoyo

It can inherently collect items, equivalent to a yoyo with Collecting I. Any further enchantment increases the item limit.

The Terra Chaser

With a whistle and the swing of your fist, it will seek out an enemy and attack it. The Terra Chaser needs mana to do so, however.

It can also be combined with an elementium yoyo to give the Terra Chaser the ability to collect items.

If you think something is too overpowered, underpowered, or broken in general, please, let me know. Balancing is hard to do without any testers.
