@Rob Miracle
Can I? its a local function for an object,
I spawn 10 balls on the top of the screen and then(after 4 seconds), when a boolean is true , I want them all to move 100 pixels down
Please let me know if there is a better way
Roy.
yes it can be done. if you show some code it would be easier to show how to do it
Ok thanks for trying to help
[lua]
– dispatch event to the initial drop
local tmr= timer.performWithDelay(2000,gem:dispatchEvent({name=“initDrop_listener” , state=“on”}),1)
–spawn the gems
for i=0 ,8 do
local gem = display.newSprite( gemSheet, sequenceData )
gem.width = 40
gem.height = 40
gem.x = 20
gem.y = 424-40*i
gem.MyRow = (gem.y - firstRowY + gemDimentions)/gemDimentions
gem.MyCol = (gem.x - firstColX + gemDimentions)/gemDimentions
gem.MyGemID = board[gem.MyRow][gem.MyCol]
gem:setSequence( “gem” … gem.MyGemID )
gem:play()
gem.xScale=0.5
gem.yScale=0.5
gem.y = (-gem.MyRow*gemDimentions)
– start the initial drop function
local function initDrop_listener( event )
if event.state == “on” then
print(“drop success”) – debug that its firing
gem:removeEventListener( “initDrop”, initDrop_listener )
end
end
gem:addEventListener( “initDrop”, initDrop_listener )
end
end
[/lua]
Obviously im doing something wrong 
Roy.
first line 2 name should be “initDrop”
second cause of the way your creating the balls this will only affect the last one created cause your over writing each one as the new one is created
try this
local gems = {} local function createBall(i) local gem = display.newSprite( gemSheet, sequenceData ) gem.width = 40 gem.height = 40 gem.x = 20 gem.y = 424-40\*i gem.MyRow = (gem.y - firstRowY + gemDimentions)/gemDimentions gem.MyCol = (gem.x - firstColX + gemDimentions)/gemDimentions gem.MyGemID = board[gem.MyRow][gem.MyCol] gem:setSequence( "gem" .. gem.MyGemID ) gem:play() gem.xScale=0.5 gem.yScale=0.5 gem.y = (-gem.MyRow\*gemDimentions) local function initDrop( ) print("drop success") -- debug that its firing end gem.tmr= timer.performWithDelay(2000, initDrop, 1) return gem end for i = 1, 8 do gems[i] = createBall(i) end do away with the eventListener
But doesnt that mean that each gem has its own timer? cause the line
[lua]gem.tmr= timer.performWithDelay(2000, initDrop, 1)[/lua]
Is inside the spawned gems… I want the timer to be outside, is it possible?

First I want to thank you for your patient with helping me!
I get an error when I try this,
The error is - Attempt to index global ‘gem’ (a nil value)
And its referenced to the ‘addEventListener’ inside the loop…
Ive attached the project file, do you mind take a look at it?
The relevant rows are 64-95
Roy.
made edits to code above
will look at file but will be a while its 3am here gotta go bed
great
nite
