From 5af7956318ba51f4fe5b346a749f99ae8f788c58 Mon Sep 17 00:00:00 2001 From: chihya72 Date: Mon, 10 Aug 2026 17:13:02 +0800 Subject: [PATCH] =?UTF-8?q?feat:=20=E6=9C=AA=E6=8B=A5=E6=9C=89=E6=8A=80?= =?UTF-8?q?=E8=83=BD=E5=8D=A1=E7=9A=AE=E8=82=A4=E6=97=B6=E4=B9=9F=E6=92=AD?= =?UTF-8?q?=E6=94=BE=E8=AF=A5=E5=8D=A1=E7=9A=84=20cut-in=20=E6=BC=94?= =?UTF-8?q?=E5=87=BA?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 考试内所有皮肤表现都由 ExamCardData.ProduceCardSkinId 派生： PrePlayCardAsync -> PlayCutInAsync(skinId) -> TryGetCutInParams -> mov_{id}_skillcard.usm + cutInType，以及 ExamCardButtonImage -> GetThumbnailLoopMovieName(skinId) 的手牌循环缩略图。 于是在该 getter 上，把没挂皮肤的卡按 produceCardId 补成主表里 CutInType 最高的皮肤 id，一个 hook 覆盖 cut-in 与手牌缩略图。 映射表从 ProduceCardSkinMaster 惰性构建一次。 跟随 dbgMode 生效，不额外加配置项和 GUI 开关。 已知代价：该 getter 另有 ExamDataSerializeData 与 ExamParameterModel 两个读取方，伪造的 skinId 会进考试状态序列化和 play log， 竞赛回放会随之上传。 Co-Authored-By: Claude Opus 5 --- src/GakumasLocalify/Hook.cpp | 74 ++++++++++++++++++++++++++++++++++++ 1 file changed, 74 insertions(+) diff --git a/src/GakumasLocalify/Hook.cpp b/src/GakumasLocalify/Hook.cpp index 7d2e294..060aee7 100644 --- a/src/GakumasLocalify/Hook.cpp +++ b/src/GakumasLocalify/Hook.cpp @@ -1724,6 +1724,75 @@ namespace GakumasLocal::HookMain { return AddPhotographyIdolSkinItems(ret, characterId ?
