SMP PVP MODE

[英文版本在下方 | The English version is below]

PVP Mod 是一个为 Minecraft SMP 服务器设计的竞技场地 PVP 模组。该模组通过自动化场地管理、装备发放和战斗规则，为服务器管理员提供了完整的竞技场解决方案。

场地管理

模组支持两种场地模式：

生成模式 (Generate) 自动生成临时竞技场地，战斗结束后自动清理，不污染主世界。场地结构固定为三层：基岩层(Y=317)、草方块层(Y=318)、光源层(Y=319)，可配置场地尺寸和生成坐标范围。玩家传送位置在光源层上方(Y=319)。

传送模式 (TP) 使用预先建造的竞技场，通过配置传送点实现玩家快速传送。支持多场地并发，自动检测场地占用状态，避免冲突。

装备系统

战斗前自动保存玩家原有装备、生命值和饥饿值，战斗期间发放临时装备，战斗结束后恢复原状态。

支持配置的装备类型：

• hotbar - 快捷栏（9个格子）
• inventory - 背包（27个格子）
• armor - 盔甲（头盔、胸甲、护腿、靴子）
• offhand - 副手（手持盾牌等）

所有装备都支持附魔配置。

生命饥饿值恢复

传送至竞技场后可自动回满生命值和饥饿值，战斗结束后恢复传送前的状态。此功能可在配置中开启或关闭。

安全机制

• 战斗期间禁止丢弃装备，防止刷物资
• 世界边界限制，防止玩家逃跑
• 玩家数据持久化到磁盘，支持服务器重启后恢复

玩家体验

• 纯服务端运行，玩家无需安装客户端模组
• 聊天按钮交互，操作便捷
• 同意决斗后进入旁观模式，倒计时期间禁止移动
• 倒计时结束自动切换到战斗模式，可正常移动和攻击
• 夜视效果，确保场地可见

2. 点击消息中的"接受"按钮（或使用 /duel accept 命令）
3. 系统保存双方玩家的原始数据（装备、生命值、饥饿值、位置、游戏模式）
4. 双方玩家切换到旁观模式
5. 系统生成或分配竞技场地
6. 传送双方玩家到场地
7. 开始倒计时

2. 玩家可以正常移动和攻击
3. 世界边界限制玩家移动范围
4. 禁止丢弃装备

战斗结束

1. 一方玩家阵亡后，战斗结束

性能优化

生成模式优化

• 采用异步分批次生成，每批次处理2048个方块
• 区块预加载在异步线程执行
• 方块数据准备在异步线程完成
• 推荐场地尺寸为64x64

传送模式优化

• 预加载场地区块
• 配置足够的场地数量
• 合理设置世界边界

数据持久化

玩家数据（装备、生命值、饥饿值、位置、游戏模式）在战斗开始时保存到内存和磁盘。服务器重启后，系统自动恢复离线玩家的数据。

数据文件位置：

世界目录/data/pvpmod_pending_restore.dat

注意事项

配置热重载

使用 /pvp reload 命令可以在不重启服务器的情况下重载配置，但不会影响正在进行的决斗。

更新配置文件

当模组版本更新后，如果配置文件没有更新，可以删除旧配置文件，服务器重启后会自动生成新的配置文件。

版本兼容性

模组理论上支持 Minecraft 1.21.1，但编译时使用的是 1.21.1 的 API。新版本如有重大 API 变更，可能需要重新编译。

故障排查

配置错误

检查配置文件格式是否正确，使用 JSON 验证工具确保语法无误。配置文件必须包含 display-name 和 arena-mode 字段。

场地问题

生成模式场地未生成时，检查区块加载状态和内存使用。传送模式场地问题时，检查传送点坐标是否有效。

装备问题

装备未发放或未恢复时，检查物品ID是否正确，检查数据文件是否完整。

玩家卡住

如果玩家在战斗结束后卡住，可能是因为玩家数据未正确恢复。可以尝试使用 /duel list 命令查看是否有进行中的决斗，或重启服务器。

性能问题

TPS下降时，检查是否有大量场地同时生成，考虑使用传送模式或增加服务器资源。

扩展指南

添加新玩法

在配置文件中添加新的玩法配置块，设置场地模式、装备配置和游戏规则，使用 /pvp reload 命令重载配置即可生效。

修改现有玩法

编辑配置文件中的玩法配置，保存后使用 /pvp reload 命令使修改生效。

自定义场地设计

传送模式支持任意设计的场地，只需配置玩家传送位置和视角方向即可。

Overview

PVP Mod is a competitive arena PVP mod designed for Minecraft SMP servers. This mod provides a complete arena solution for server administrators through automated arena management, equipment distribution, and battle rules.

Core Features

Arena Management

The mod supports two arena modes:

Generate Mode Automatically generates temporary arenas that are cleaned up after battles, keeping the main world unpolluted. Arena structure has three fixed layers: bedrock layer (Y=317), grass block layer (Y=318), light layer (Y=319). Player teleport position is above the light layer (Y=319).

TP Mode Uses pre-built arenas, enabling fast player teleportation through configured spawn points. Supports multiple concurrent arenas with automatic arena occupancy detection to avoid conflicts.

Equipment System

Automatically saves player's original equipment, health, and hunger before battle, distributes temporary equipment during battle, and restores original state after battle ends.

Supported equipment types:

• hotbar - 9 slots
• inventory - 27 slots
• armor - helmet, chestplate, leggings, boots
• offhand - shield, etc.

All equipment supports enchantment configuration.

Health & Hunger Restoration

Can automatically restore health and hunger to max when teleporting to arena, and restore original values after battle ends. This feature can be enabled or disabled in config.

Security

• Prevents item dropping during battle to prevent item duplication
• World border limits to prevent players from escaping
• Player data persisted to disk, supports recovery after server restart

Player Experience

• Server-side only, no client mod required
• Chat button interaction, easy to operate
• Enter spectator mode after accepting duel, movement disabled during countdown
• Automatically switch to battle mode after countdown, normal movement and attack
• Night vision effect for arena visibility

Built-in Game Modes

1. Battle ends when one player dies
2. Winner immediately restores original equipment, health, hunger, and teleports back to original position
3. Loser restores original equipment, health, hunger, and teleports back to original position after clicking respawn
4. Arena is cleaned up (generate mode) or released (TP mode)

Performance Optimization

Generate Mode Optimization

• Uses asynchronous batch generation, processing 2048 blocks per batch
• Chunk preloading executed in async thread
• Block data preparation completed in async thread
• Recommended arena size is 64x64

TP Mode Optimization

• Preload arena chunks
• Configure sufficient arenas
• Set appropriate world borders

Data Persistence

Player data (equipment, health, hunger, position, game mode) is saved to memory and disk when battle starts. After server restart, the system automatically restores offline players' data.

Data file location:

World Directory/data/pvpmod_pending_restore.dat

Notes

Config Hot Reload

Use /pvp reload command to reload config without server restart. This does not affect ongoing duels.

Update Config File

When mod version is updated, if config file is not updated, you can delete the old config file. A new config file will be automatically generated when server restarts.

Version Compatibility

This mod theoretically supports Minecraft 1.21.1, but is compiled using 1.21.1 API. If new versions have major API changes, recompilation may be required.

Troubleshooting

Config Errors

Check if config file format is correct. Use JSON validation tools to ensure syntax is correct. Config file must contain display-name and arena-mode fields.

Arena Issues

For generate mode arena not generating, check chunk loading status and memory usage. For TP mode arena issues, check if spawn point coordinates are valid.

Equipment Issues

When equipment is not distributed or restored, check if item IDs are correct and if data files are complete.

Player Stuck

If player is stuck after battle ends, it may be because player data was not restored correctly. Try /duel list command to check for ongoing duels, or restart server.

Performance Issues

When TPS drops, check if multiple arenas are generating simultaneously. Consider using TP mode or increasing server resources.

Extension Guide

Add New Game Mode

Add a new game mode config block in the config file, set arena mode, equipment config, and game rules. Use /pvp reload command to make it take effect.

Modify Existing Game Mode

Edit the game mode config in the config file, save, and use /pvp reload command to make changes take effect.

Custom Arena Design

TP mode supports arenas with any design, just configure player teleport positions and view directions.
