lua部分 tips

lua文件刷新

function require_ex( _mname )    if _mname == "" then        return    end  if package.loaded[_mname] then  end  package.loaded[_mname] = nil  require( _mname )end

lua字符串分割

function Split(szFullString, szSeparator)      local nFindStartIndex = 1      local nSplitIndex = 1      local nSplitArray = {}      while true do         local nFindLastIndex = string.find(szFullString, szSeparator, nFindStartIndex)         if not nFindLastIndex then              nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, string.len(szFullString))              break         end         nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, nFindLastIndex - 1)         nFindStartIndex = nFindLastIndex + string.len(szSeparator)         nSplitIndex = nSplitIndex + 1      end      return nSplitArray  end  

遍历lua数组

 

方法一,可以用for来遍历:[cpp] view plaincopy在CODE上查看代码片派生到我的代码片do      table_week = {      "w",      "e",      "r",      "t",      "y",      "u",      "i",      }        for i = 1, #table_week do          print(table_week[i])      end  end  #后面接一个数组或者tabe来遍历它,i是该table或者数组的起始下标。方法2:[cpp] view plaincopy在CODE上查看代码片派生到我的代码片do      table_week = {      "w",      "e",      "r",      "t",      "y",      "u",      "i",      }      for i, v in pairs(table_week) do          print(i)      end  end  这种是采用迭代器的方式遍历的,i为下标,v为table或者数组的值。方式3:[cpp] view plaincopy在CODE上查看代码片派生到我的代码片do      table_week = {      "w",      "e",      "r",      "t",      "y",      "u",      "i",      }      for i in pairs(table_week) do          print(i);      end  end  i为table或者数组的下标。方式4:[cpp] view plaincopy在CODE上查看代码片派生到我的代码片do  table_view = {      "w",      "e",      "r",      color1 = "red",      color2 = "blue",      {"a1", "a2", "a3"},      {"b1", "b2", "b3"},      {"c1", "c2", "c3"},  }  for i, v in pairs(table_view) do      if type(v) == "table" then          for new_table_index, new_table_value in pairs(v) do              print(new_table_value)          end      else          print(v)      end  end    end  注:type(v)功能:返回参数的类型名("nil""number", "string", "boolean", "table", "function", "thread", "userdata")
