DNF90 服务端与启动器完整源码（含 GM 工具功能增强）
服务端（Go）： - GM 塞背包/带属性装备发放：在线角色推送 op14 增量物品行，背包实时刷新，无需回角色选择界面 - GM 改金币/改等级：去掉在线拒绝，落库后推送 op14 钱包/op37 等级状态，在线实时刷新 - 等级端点统一切换到新版 GMSetCharacterLevel（自带在线刷新） - 无限/锁死疲劳模式 + 燃烧疲劳：每房间消耗 2 点、打怪与通关经验双倍 - 燃烧疲劳开关时给所有在线角色推送系统提示（op12 mode 0） - 深渊史诗掉率：GM 全局倍率 + 城镇增益药剂窗口倍率，真实接入掉落结算 启动器（Python/JS）： - 标题栏自绘、窗口 1204x717、禁止拖拽改大小、仅最小化/关闭 - GM 工具：疲劳与燃烧、深渊史诗掉率、拍卖行上架（单一定价对齐） - 拍卖行上架前端对齐服务端单一价格语义，修复 400 报错

// 本文件是「支援兵能否用现有客户端渲染」的可行性实验。
|
||||
//
|
||||
// 背景
|
||||
// 支援兵的官方实现（Server-90 的 client-patch）把渲染逻辑**补丁进 DB4 客户端**，
|
||||
// 而本部署的客户端是另一个 EXE 版本（8A7AF614…），那些硬编码地址全都对不上。
|
||||
//
|
||||
// 但现有服务端里已经有一条「服务端创建 actor → 客户端渲染另一个玩家角色」的通道：
|
||||
// sendTownRemoteActorRecord / sendTownRemoteActorProjection
|
||||
// 它的注释明确写着这是「**正在渲染副本实例的客户端**收到的形态」，
|
||||
// mode0 是客户端 user table 解析同伴名字/等级/头像的依据。
|
||||
//
|
||||
// 唯一挡路的是 sendTownRemoteActorProjectionWithContext 开头那道门：
|
||||
// if ... || actor.Session == nil || actor.CharacterID == 0 { return nil }
|
||||
// 「actor 必须是一个真实在线玩家」。支援兵是离线角色，所以走不通。
|
||||
//
|
||||
// 本实验绕过那道门，直接复用同一批构造器与同一套发包顺序：
|
||||
// mode0（创造 actor）→ mode1（绑定装备/技能）→ op9（组队框）
|
||||
// 用**接收者自己的会话**当账号上下文，把另一个角色当成远端 actor 下发。
|
||||
//
|
||||
// 目的只有一个：观察客户端会不会把它画出来。
|
||||
// 这不是支援兵的最终实现 —— 只是决定路线（纯服务端 vs 必须换客户端）的判据。
|
||||
|
||||
// GMCompanionRenderExperimentForCharacter 按在线角色 id 触发渲染实验。
|
||||
//
|
||||
// 供 admin 端点使用：只有该角色**当前在线**才能下发 actor 包
|
||||
// （包必须投递到一个活的连接上）。
