C++ (Cpp) MLVL Example

Introduction

The c++ (cpp) mlvl example is extracted from the most popular open source projects, you can refer to the following example for usage.

Programming language: C++ (Cpp)

Class/type: MLVL

Example#1
File: MLVL.hppProject: KalDragon/urde

 static bool Extract(const SpecBase& dataSpec,
                     PAKEntryReadStream& rs,
                     const hecl::ProjectPath& outPath,
                     PAKRouter<PAKBridge>& pakRouter,

                     bool force,
                     std::function<void(const hecl::SystemChar*)> fileChanged)

     MLVL mlvl;
     mlvl.read(rs);
     FILE* fp = hecl::Fopen(outPath.getWithExtension(_S(".yaml"), true).getAbsolutePath().c_str(), _S("wb"));

                                       entry, force, fileChanged);
