Question

嘿所以我一直试图弄清楚这一点，但没有运气。我有8个随机洗牌的产卵，他们应该产卵两行4。我遇到的问题是，所有8似乎只产卵在第一排。

所以基本上这样：
[1] [2] [3] [4] [5] [6] [7] [8]
[] [] [] []

当它应该是这样的：
[1] [2] [3] [4]
[5] [6] [7] [8]

我理解它的事实，我定位每个球体在做以Y轴为中心，但不知道该怎么做，这样如果4个位置被占用，然后向下移动到第二行。

干杯，

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

尝试是这样的：

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
