Bingo Parachute

Bingo Parachute is a server-side Fabric addon for Yet Another Bingo.

It replaces the normal ground spawn opening with a configurable airdrop flow at the start of a Bingo match. The current feature set includes:

  • High-altitude match start
  • BAT and ELYTRA airdrop modes
  • Early-match PVP protection
  • Temporary inventory and equipment custody during descent
  • Short fall-damage immunity after BAT manual release and timeout cleanup
  • Automatic finish on ground, water, or lava contact

Current Status

The project is already usable for in-game testing. The main implemented flow includes:

  • Hooking into the Bingo lifecycle
  • Pinning players to future airdrop anchors during Bingo COUNTDOWN
  • Entering the actual airdrop flow after PLAYING
  • BAT airdrop mode
  • ELYTRA airdrop mode
  • Early-match PVP protection
  • Timeout handling
  • Fall-damage immunity after timeout and BAT manual release
  • Cleanup and restoration after landing

The mod is server-side only and does not require clients to install anything.

Supported Versions

  • mc1.21.11
  • mc1.21.8

Project layout:

  • common Shared flow, state, configuration, and logic that avoids direct Minecraft coupling where possible
  • mc1.21.11 Version-specific implementation for 1.21.11
  • mc1.21.8 Version-specific implementation for 1.21.8

Flow Overview

The current gameplay flow is:

  1. After Bingo initializes, this mod registers and waits for lifecycle events
  2. When Bingo enters COUNTDOWN, the mod computes and caches high-altitude airdrop anchors
  3. During COUNTDOWN, players are pinned at those high-altitude anchors instead of their normal ground spawn positions
  4. After Bingo enters PLAYING, the mod creates the airdrop session for the current match
  5. When activation time is reached:
    • The player's inventory and equipment are captured and cleared
    • The player enters BAT or ELYTRA mode
  6. During the airdrop, the mod continuously handles:
    • Flight control
    • PVP protection
    • Timeout countdown
    • Finish checks for ground, water, lava, or death
  7. After the airdrop finishes:
    • Temporary carriers or abilities are cleaned up
    • Short fall-damage immunity is applied when needed
    • The original inventory and equipment are restored
    • The player is removed from active airdrop tracking

Configuration

Main configuration fields:

  • enabled Enables or disables the addon entirely.
  • debugLogging Enables more verbose debug logging.
  • mode Selects the active airdrop mode, BAT or ELYTRA.
  • startDelayTicks Delay after PLAYING before the airdrop begins when countdown anchors are not being reused.
  • spawnHeight Target height of the airdrop start position.
  • pvpProtectionSeconds Length of early-match PVP protection. This also defines the base airdrop timeout duration.
  • timeoutFallImmunitySeconds Extra fall-damage immunity duration after forced timeout cleanup. BAT manual Shift release currently reuses the same duration.
  • bat.descentSpeed Fixed base descent speed in BAT mode.
  • bat.flightSpeed Flight speed scalar in BAT mode. The player's look direction changes how this scalar is distributed into horizontal and vertical components.
  • bat.maxHorizontalRadiusChunks Maximum horizontal distance from the origin in BAT mode, measured in chunks. Values below 0 mean unlimited.
  • elytra.glideSpeedScale Glide speed scale for ELYTRA mode.
  • elytra.maxDiveSpeed Maximum dive speed for ELYTRA mode.
  • elytra.maxHorizontalRadiusChunks Maximum horizontal distance from the origin in ELYTRA mode, measured in chunks. Values below 0 mean unlimited.

Current default examples:

  • mode = BAT
  • spawnHeight = 196
  • pvpProtectionSeconds = 30
  • timeoutFallImmunitySeconds = 10
  • bat.descentSpeed = 0.33
  • bat.flightSpeed = 0.6
  • bat.maxHorizontalRadiusChunks = 10.0

Dependencies

This mod requires the server to also have:

  • Yet Another Bingo
  • Fabric API

Acknowledgements

  • The code and docs were developed with substantial assistance from OpenAI Codex

Disclaimer

  • This project is a typical vibe coding product, built with a bias toward fast iteration and experimentation
  • The current implementation has only received limited compile-time verification and in-game testing, and should not be treated as a fully audited, fully validated, or long-term supported production release
  • No guarantees are provided for code quality, edge-case behavior, cross-version compatibility, performance, or potential data/save risks; evaluate carefully and back up your environment before using it on a production server
  • If you find a bug, feel free to open an issue; vulnerabilities and clear functional defects will be fixed when possible, but new feature development, behavior expansion, and long-term version support are not guaranteed

TODO

These goals are clear, but not finished yet:

  • Test the full in-game behavior and edge cases of ELYTRA mode
  • Test full in-game compatibility on 1.21.8
  • Support more Minecraft versions

Bingo Parachute

Bingo Parachute 是一个只面向 Yet Another Bingo 的服务端附属 Fabric mod。

它会在 Bingo 开局时把参赛玩家接管到高空空降流程里，而不是直接从地面出生点开始。当前主要目标是给 Bingo 提供一个可配置的开局空降体验，包括：

  • 高空起跳
  • BAT / ELYTRA 两种模式
  • 开局前几秒强制 PVP 保护
  • 空降期间背包与装备托管
  • BAT 手动脱离和超时后的短时摔落免疫
  • 落地、落水、落岩浆后的自动结束

当前状态

当前项目已经可以用于实机测试，主链路包括：

  • 通过 Bingo 生命周期事件接入游戏流程
  • 在 Bingo COUNTDOWN 阶段把玩家固定到未来空降起点
  • 在 PLAYING 后正式进入空降
  • BAT 模式空降
  • ELYTRA 模式空降
  • 开局 PVP 保护
  • 超时处理
  • 超时和 BAT 手动脱离后的摔落免疫
  • 落地后的结束、恢复和清理

当前实现是服务端 mod，不要求客户端安装。

当前支持版本

  • mc1.21.11
  • mc1.21.8

项目结构：

  • common 放公共流程、状态、配置和尽量不依赖 Minecraft 类型的逻辑
  • mc1.21.11 放 1.21.11 的版本实现
  • mc1.21.8 放 1.21.8 的版本实现

游戏流程概览

当前实际流程大致是：

  1. Bingo 初始化后，本 mod 注册并等待生命周期事件
  2. Bingo 进入 COUNTDOWN 时，本 mod 计算并缓存高空空降起点
  3. COUNTDOWN 期间把玩家固定在高空起点，而不是原地面出生点
  4. Bingo 进入 PLAYING 后创建本局空降 session
  5. 到达激活时机后：
    • 备份并清空玩家背包/装备
    • 进入 BAT 或 ELYTRA 模式
  6. 空降过程中持续处理：
    • 飞行控制
    • PVP 保护
    • 超时倒计时
    • 落地/落水/落岩浆/死亡判定
  7. 空降结束后：
    • 清理临时载具或能力
    • 在需要时给予短时摔落免疫
    • 恢复原始背包/装备
    • 从活跃空降跟踪中移除

配置

当前主要配置项：

  • enabled 是否启用整个附属 mod。
  • debugLogging 是否输出更详细的调试日志。
  • mode 当前空降模式，BAT 或 ELYTRA。
  • startDelayTicks 不复用 COUNTDOWN 高空锚点时，PLAYING 后延迟多少 tick 再正式进入空降。
  • spawnHeight 空降起点的目标高度。
  • pvpProtectionSeconds 开局 PVP 保护时长，同时也是空降超时基准时长。
  • timeoutFallImmunitySeconds timeout 强制结束后额外给予的摔落免疫时长；BAT 模式手动 Shift 脱离后当前也沿用这段时长。
  • bat.descentSpeed BAT 模式的固定基础下降速度。
  • bat.flightSpeed BAT 模式的飞行速度标量，视角会改变其水平/垂直分量分配。
  • bat.maxHorizontalRadiusChunks BAT 模式允许偏离起点的最大水平半径，单位为区块；小于 0 视为无限。
  • elytra.glideSpeedScale ELYTRA 模式的滑翔速度缩放。
  • elytra.maxDiveSpeed ELYTRA 模式允许的最大俯冲速度。
  • elytra.maxHorizontalRadiusChunks ELYTRA 模式允许偏离起点的最大水平半径，单位为区块；小于 0 视为无限。

当前默认值示例：

  • mode = BAT
  • spawnHeight = 196
  • pvpProtectionSeconds = 30
  • timeoutFallImmunitySeconds = 10
  • bat.descentSpeed = 0.33
  • bat.flightSpeed = 0.6
  • bat.maxHorizontalRadiusChunks = 10.0

依赖

运行这个 mod 需要服务器同时安装：

  • Yet Another Bingo
  • Fabric API

TODO

这些目标已经明确，但目前还没有完成：

  • 测试 ELYTRA 模式的完整实机表现与边界行为
  • 测试 1.21.8 版本的完整实机兼容性
  • 支持更多 Minecraft 版本
