为什么C++看不到我的 lua 脚本文件？

Why C++ can't see my lua script file?

本文关键字：脚本 文件 lua 我的 C++ 看不到 为什么      更新时间：2023-10-16

我在集成Lua和c++时有一个简单的问题。我有我的项目在Visual Studio:https://i.stack.imgur.com/nNw6H.png

，然后运行lua_init()函数:

bool lua_init(std::string &luaScriptName){
// Create the Lua state. Explanation from Lua 5.1 Ref. Manual:
globalL = luaL_newstate(); // 5.1 OK - Lua 5.0 or lower will probably require different commands
if( globalL == NULL )
    return false;
    // Loads all Lua standard libraries
luaL_openlibs(globalL);  // 5.1 OK - Lua 5.0 or lower will require different commands
// This lot below could be replaced with luaL_dofile, but that just does: luaL_loadfile(..) || lua_pcall(..), which gives no reporting of error messages etc.
int initError = luaL_loadfile(globalL,luaScriptName.c_str());
switch( initError )
{
    case 0:
        // The file loaded okay, so call it as a protected function - to stop fatal errors from exiting the program
        lua_pcall(globalL,0,0,0);
        break;
    case LUA_ERRFILE:
        std::cerr<<"Cannot find / open lua script file: "<<luaScriptName<<std::endl<<"Skipping Lua init."<<std::endl;
        break;
    case LUA_ERRSYNTAX:
        std::cerr<<"Syntax error during pre-compilation of script file: " <<luaScriptName<<std::endl<<"Skipping Lua init."<<std::endl;
        break;
    case LUA_ERRMEM:
        // Treating this as fatal, since it means other Lua calls are unlikely to work either
        std::cerr<<"Fatal memory allocation error during processing of script file: " <<luaScriptName<<std::endl;
        return false;
}
return true;

}

但不知道我得到"无法找到/打开lua脚本文件:"错误

应该指向我的脚本吗?如何使用Visual Studio ?文件位于项目目录

您的代码将在二进制文件所在的位置执行，或者在调试模式下的目标目录中执行。因此，在执行二进制文件时，请检查lua文件是否可以访问。如果它与源文件在一起，当然，它是不可访问的。
