Question

我试图为我的游戏创建一个随机字母答案，但问题是它不会检测到图像请帮助......

local s = answer --answer
local len = string.len(answer)
local str 
local j

for j=1,len do
    str = s:sub(j,j)
    arr_str[j]= str 
end

    for i = 1, #arr_str do
        local j = math.random( 1,#arr_str)
        arr_str[i], arr_str[j] = arr_str[j], arr_str[i]
    end

local max = #arr_str
local rowMax = max
--if max > 8 then rowMax = 8 end
local gap = 35
local xPos = halfW - (rowMax/2*35) + 17.5
local yPos = bottom - 20
local startpos = xPos



for i= 1, #arr_str do

    slot = display.newImageRect( "images/bg_slot.png", 43, 43 )
    slot.x = xPos; slot.y = yPos -40
    slotgroup:insert( slot )

    slot1 = display.newImageRect( "images/ans_slot.png", 43, 43 )
    slot1.x = xPos; slot1.y = yPos 
    slotgroup:insert( slot1)

    print("ERROR",arr_str[i])
    letter = display.newImageRect("letters/uc/".. arr_str[i] ..".png",50,50)    
    letter.name = arr_str[i] 
    letter.x = xPos; letter.y = yPos
    letter.idBg = i
    lettergroup:insert( letter)

    xPos = xPos + gap

Answer 1

您尝试打开的图像可能不存在。

打印图像的整个路径（下面的代码）并在项目文件夹中查找它以确保您确实拥有该图像（同时注意文件扩展名。

print("letters/uc/".. arr_str[i] ..".png")

试图将upvalue＆＃39; letter＆＃39;错误因为或arr_str [i]
