这是代码。我创建了一个名为addbalo的表，并在函数scene:createScene中添加了精灵。当我从ScreenGroup:insert(player)中取出精灵时。使用它的每个其他功能都不再起作用。例如，精灵播放器曾经是sprite的一部分但是当我将它移动到一个函数以便计时器工作时，使用它的其他所有东西都不再起作用。
功能local storyboard = require( "storyboard" )
local scene = storyboard.newScene()
local mydata = require( "mydata" )
local physics = require("physics")
physics.start()
players = {}
local function start(event)
if event.phase == "began" then
addbaloTimer = timer.performWithDelay(1000, addbalo, -1)
end
end
local function addbalo()
