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
