Lua（Corona SDK）Android问题-间隔为空

Question

在 PC 上，我的游戏可以正常编译并正常运行，但是一旦我为 Android 构建它，我就会收到这个奇怪的错误代码：

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

此错误代码来自的代码行是：

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

整个代码段：

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

错误消息bad argument #1 to 'random' (interval is empty) 表示您正在尝试将零传递给math.random()。
换句话说，你的wordsList 数组是空的。
