Question

嘿所以我一直試圖弄清楚這一點，但沒有運氣。我有8個隨機洗牌的產卵，他們應該產卵兩行4。我遇到的問題是，所有8似乎只產卵在第一排。

所以基本上這樣：
[1] [2] [3] [4] [5] [6] [7] [8]
[] [] [] []

當它應該是這樣的：
[1] [2] [3] [4]
[5] [6] [7] [8]

我理解它的事實，我定位每個球體在做以Y軸爲中心，但不知道該怎麼做，這樣如果4個位置被佔用，然後向下移動到第二行。

乾杯，

function spawnBase() 
shuffleOrbArray(orbList) 

for i=1, #orbList do 
    local orbName = orbList[i] 
    local posX = (i-1)*67+60 

    if orbName == "red" then 

     redPlace = display.newImageRect("Shapes/red-placeholder.png", 57,57) 
     redPlace.y = _H/2 
     redPlace.x = posX 
     redPlace.alpha = 1 
     redPlace.id = "Red"    
     orbName:insert(redPlace) 
     redPlace:addEventListener("tap", revealColor) 

    elseif orbName == "green" then 
     --create green enemy 

     greenPlace = display.newImageRect("Shapes/green-placeholder.png", 57,57) 
     greenPlace.y = _H/2 
     greenPlace.x = posX 
     greenPlace.alpha = 1 
     greenPlace.id = "Green" 
     orbName:insert(greenPlace) 
     greenPlace:addEventListener("tap", revealColor) 

     elseif orbName == "yellow" then 
     --create green enemy

嘗試是這樣的：

local cols = 4 
local orbList = { "a", "b", "c", "d", "e", "f", "g", "h" } 

for i=1, #orbList do 
    local c = (i - 1) % cols 
    local r = math.floor((i - 1)/cols) 
    print(c, r, orbList[i]) 

    local posX = c * sizeX 
    local posY = r * sizeY 
end
