科羅娜SDK：把項目通過創建中的函數表

Question

我無法弄清楚如何把一個簡單的函數創建的對象在一個表中，有他們的身影如個人身份..

例如

local function spawncibo() 
nuovoCibo = display.newImage("immagini/cibo/cibo001.png") 
end 
timer.performWithDelay(1500, spawncibo, -1) 

我試圖用一個做for循環，但它不工作（如果我嘗試打印表格，我總是得到一個無結果）。

任何建議將非常感激！

Answer 1

提供我理解正確你的問題，你可以嘗試這樣的事：

local cibo = {} 
local function spawncibo() 
    cibo[#cibo+1] = display.newImage(string.format(
    "immagini/cibo/cibo%3d.png", #cibo+1)) 
end 
timer.performWithDelay(1500, spawncibo, -1) 

這將讀取文件cibo001.png，cibo002.png，每1.5秒......並把所有圖像導入cibo陣列。

Answer 2

local spawnedCibos = {} 
local function spawncibo() 
    nuovoCibo = display.newImage("immagini/cibo/cibo001.png") 
    table.insert(spawnedCibos, nuovoCibo); 
end 
timer.performWithDelay(1500, spawncibo, -1); 

local function enterFrameListener(event) 
    for index=#spawnedCibos, 1, -1 do 
     local cibo = spawnedCibos[index]; 
     cibo.x = cibo.x + 1; 
     if cibo.x > display.contentWidth then 
      cibo:removeSelf(); 
      table.remove(spawnedCibos, index); 
     end 
    end 
end

你可以試試這個...

local spawned = {} -- local table to hold all the spawned images 
local timerHandle = nil -- local handle for the timer. It can later be used to cancel it if you want to 

local function spawnCibo() 
    local nuovoCibo = display.newImage('immagini/cibo/cibo001.png') 
    table.insert(spawned, nuovoCibo) -- insert the new DisplayObject (neovoCibo) at the end of the spawned table. 
end 

local function frameListener() 
    for k, v in pairs(spawned) do -- iterate through all key, value pairs in the table 
     if (conditions) then -- you will probably want to change conditions to some sort of method to determine if you want to delete the cibo 
      display.remove(spawned[k]) -- remove the part of the object that gets rendered 
      spawned[k] = nil -- remove the reference to the object in the table, freeing it up for garbage collection 
     end 
    end 
end 

timer.performWithDelay(1500, spawnCibo, 0) -- call spawnCibo() every 1.5 seconds, forever (That's what the 0 is for) or until timer.cancel is called on timerHandle 
Runtime:addEventListener('enterFrame', frameListener) --
