This project is about a Minecraft plugin for Spigot servers. It adds a grappling hook mechanism to the game.
Enchanting a fishing hook with "riptide" turns it into a grappling hook. This tool can be used to climb mountains or buildings by right-clicking in a direction to launch the hook, then holding the right-click to climb.
You can also apply the enchant "durability" in order to improve the durability of your grappling hook.
The plugin listens for the "fishing" event, it checks if the hook is on the ground, and it checks if the item is enchanted with "riptide". It pulls the player using an acceleration equal to the enchantment level multiplied by the default force (in the plugin configuration). After that, it decreases the durability of the grappling hook, making it break at the end of a number of uses (in the plugin configuration).
It uses Kotlin, a high-level programming language for the Java VM. It also uses mc-kotlin, a library made by me that helps developing Minecraft plugins with Kotlin.
Installation, configuration and admin usage are on SpigotMC
