的Lua（科羅娜SDK）Android的問題 - 時間間隔爲空

Question

在PC上，我的遊戲編譯罰款和正常運行，但只要我建立它的Android我得到這個奇怪的錯誤代碼：

bad argument #1 to 'random' (interval is empty) 

線這個代碼錯誤代碼來自是：

local word = wordsList[math.random(#wordsList)] 

整個代碼Segement：

local lineCount = 1 
local wordsList = {} 
local wordAccepted = true 
local file = io.open(system.pathForFile("words.txt", system.ResourceDirectory), "r") --Open the words file from the resource folder 
for line in file:lines() do 
    if #line > 1 and #line <= 10 then 
     for i = 1,#line do 
      if string.byte(line,i)<65 or string.byte(line,i)>90 and string.byte(line,i)<97 or string.byte(line,i)>122 then 
       wordAccepted = false 
      end 
     end 
     if wordAccepted == true then 
      print ("accepted "..line) 
      wordsList[lineCount]=string.upper(line) 
      lineCount = lineCount + 1 
     else 
      print("rejected "..line) 
     end 
    end 
end 
io.close(file) 
file = nil 
local word = wordsList[math.random(#wordsList)] 

Answer 1

錯誤消息bad argument #1 to 'random' (interval is empty)表示您正嘗試將零傳遞給math.random()。
換句話說，你的wordsList數組是空的。
