[置顶] lua进阶8-- C++读取lua文件里的三维表

来源:程序员人生   发布时间:2015-03-28 08:11:57 阅读次数:2526次

前面lua进阶里面讲到用C++读取2维表,但是最近又有了新的需求,lua文件里面出现了3维表,自己摸索了1下,终究找到了解决的方式,在这里面与大家分享1下</span>

我的lua文件里面的3维表结构以下

stage = { {m_nId = 105,m_nBoss = 0,m_nScoreList = {300,450,600},m_nRewardList = {230401201,13020801,13010411},m_nDropItemList = {0,0,0}}, {m_nId = 106,m_nBoss = 0,m_nScoreList = {630,840,1050},m_nRewardList = {241801101,14000201,18000201},m_nDropItemList = {14000101,241700301,230501301}}, {m_nId = 107,m_nBoss = 0,m_nScoreList = {735,980,1225},m_nRewardList = {230400201,230400411,230500101},m_nDropItemList = {12020101,13010301,230401401}}, {m_nId = 108,m_nBoss = 0,m_nScoreList = {840,1120,1400},m_nRewardList = {19000101,241500901,18040201},m_nDropItemList = {14000401,230401201,14000101}}, {m_nId = 109,m_nBoss = 0,m_nScoreList = {1080,1440,1800},m_nRewardList = {12020301,230600101,241800501},m_nDropItemList = {16000401,230901101,230700301}}, {m_nId = 110,m_nBoss = 1,m_nScoreList = {1200,1600,2000},m_nRewardList = {0,0,220200901},m_nDropItemList = {230902101,231101101,231000401}}
};


读取代码以下


#include <stdio.h> extern "C"{ #include "lua.h" #include "lualib.h" #include "lauxlib.h" } #include <iostream> #include <vector> #include "string.h" using namespace std; int main ( int argc, char *argv[] ) { lua_State* L; L=lua_open(); luaopen_base(L); luaopen_table(L); luaopen_string(L); luaopen_math(L); if (luaL_dofile(L, "stage.lua")) { printf("run script failed "); } else { int it_idx; int t_idx; lua_getglobal(L,"stage"); t_idx=lua_gettop(L); cout << t_idx << endl; lua_pushnil(L); while(lua_next(L,t_idx)) { it_idx=lua_gettop(L); lua_pushnil(L); //cout << "it_idx = " << it_idx << endl; int m_id = 0; while(lua_next(L,it_idx)) { const char* strkey = lua_tostring(L,⑵); if (strcmp(strkey, "m_nId") == 0) { m_id = (int)lua_tonumber(L, ⑴); cout << "m_id = " <<m_id << " "; } if (strcmp(strkey, "m_nBoss") == 0) { m_id = (int)lua_tonumber(L, ⑴); cout << "m_nBoss = " << m_id << " "; } if (strcmp(strkey, "m_nScoreList") == 0) { if (lua_istable(L, ⑴)) { cout << "m_nScoreList = " ; int ll_idx = lua_gettop(L); //cout << "ll_idx = " << ll_idx << endl; lua_pushnil(L); while (lua_next(L, ll_idx)) { cout << (int)lua_tonumber(L, ⑴) << " "; lua_pop(L, 1); } } } if (strcmp(strkey, "m_nRewardList") == 0) { if (lua_istable(L, ⑴)) { cout << " m_nRewardList = " ; int ll_idx = lua_gettop(L); // cout << "ll_idx = " << ll_idx << endl; lua_pushnil(L); while (lua_next(L, ll_idx)) { cout << (int)lua_tonumber(L, ⑴) <<" "; lua_pop(L, 1); } } } if (strcmp(strkey, "m_nDropItemList") == 0) { if (lua_istable(L, ⑴)) { cout << " m_nDropItemList = "; int ll_idx = lua_gettop(L); // cout << "ll_idx = " << ll_idx << endl; lua_pushnil(L); while (lua_next(L, ll_idx)) { cout << (int)lua_tonumber(L, ⑴) << " "; lua_pop(L, 1); } } } lua_pop(L,1); } cout << endl; lua_pop(L,1); //break; } } lua_close(L); return 0; }
