嘿家伙，我是电晕的新手，我正在尝试生成一些从天上掉到地上的物体。我已经发布了相同的代码，回答的人没有完全回答这个问题。我需要这方面的帮助，这样我才能让我的游戏走上正轨谢谢大家。有人请告诉我为什么我得到“尝试索引字段”？“（零值）”我知道某些东西不存在。给我这个问题的代码也是“object [objectTag] .x = 30 + mRandom（320）”我尝试将其注释掉并尝试在没有它的情况下工作，但错误转到下一行。有人可以帮忙吗？谢谢

local  mRandom = math.random
local   objects = {"rocket02" ,"rocket01","coin01"}
local objectTag = 0
local object = {}

  local   function spawnObject()
  objectTag = objectTag + 1
  local objIdx = mRandom(#objects)
  local objName = objects[objIdx]
  object[objectTag]  = display.newImage("image/object_"..objName..".png")
  *object[objectTag].x = 30+mRandom(320)
  object[objectTag].y = 200
  object[objectTag].name = objectTag*
  print(objectTag)
end
timer.performWithDelay(1,spawnObject,3)

能不能用这个代码块看看图片加载有没有问题

local  mRandom = math.random
local   objects = {"rocket02" ,"rocket01","coin01"}
local objectTag = 0
local object = {}

  local   function spawnObject()
  objectTag = objectTag + 1
  local objIdx = mRandom(#objects)
  local objName = objects[objIdx]
  object[objectTag]  = display.newImage("image/object_"..objName..".png")
  if object[objectTag] ~= nil then
    print( "Image succesfully loaded." )
  else
    print( "Image couldn't be found." )
  end
  *object[objectTag].x = 30+mRandom(320)
  object[objectTag].y = 200
  object[objectTag].name = objectTag*
  print(objectTag)
end
timer.performWithDelay(1,spawnObject,3)
