# PvP Kits Plugin for PaperMC 1.21.4
A customizable PvP kit plugin with GUI selection and player-specific kit layouts.
## Features
- **GUI-based kit selection** - Inventory menu for choosing kits
- **Persistent kit layouts** - Saves each player's item arrangement per kit
- **Hardcoded default kits** - Pre-configured with balanced PvP loadouts
- **Easy customization** - Simple to add new kits or modify existing ones
- **Modern 1.21.4 support** - Includes all new weapons and items
## Included Kits
| Kit Name | Icon Item | Special Features |
|------------|-----------|------------------|
| Warrior | Diamond Sword | Diamond armor, strength effect |
| Archer | Bow | Speed boost, arrows |
| Tank | Shield | Damage resistance |
| Assassin | Netherite Sword | Speed/jump boost, ender pearls |
| Mace | Mace | Wind Burst enchantment, netherite armor |
## Commands
- `/kits` - Open the kit selection GUI
- `/kits save <kitname>` - Save your current inventory as a kit layout
## Installation
1. Download the latest `.jar` from Releases
2. Place in your server's `plugins/` folder
3. Restart your server
## Configuration
Kits are hardcoded in `KitManager.java`. To modify kits:
1. Edit the `initializeKits()` method
2. Rebuild the plugin (`gradlew build`)
3. Replace the JAR file
4. Restart server
Example kit addition:
```java
Kit mage = new Kit("Mage", Material.BLAZE_ROD);
mage.setHelmet(new ItemStack(Material.LEATHER_HELMET));
// ... other armor/items ...
kits.put("mage", mage);

#
# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.
