Error in moving back to a previous scene using the director class

Director Class
#1

Hi,
i’m building a game that has three scenes ; Welcome, Menu, and the game screen
there’s an object ‘a stone’ that is supposed to be used 3 times to hit something … and after every hit i use the ’ removeSelf() ’ function to remove this stone and then generate the next one by calling this function with a nextStone button … :
local function resetStone()
stone_eg = display.newImage(“Objects/eagle_stone.png”)
localGroup:insert(stone_eg)
stone_eg.x=eagle.x-5
stone_eg.y=eagle.y+35
physics.addBody(stone_eg,“kinematic”, {density=10.0, friction=0.1, bounce=0, radius=10})
stone_eg.type=“stone”
end
…
after throwing it three times … a ‘game over’ button is shown up … and this button action is to go back to the Menu screen
the problem is when i press play again to play one more time … after the first stone hit, an error occurred

ERROR: Attempt to remove an object that’s already been removed from the stage or whose parent/ancestor group has already been removed.

in this line: stone:removeSelf()
any thoughts !!??

I have this same issue.

ERROR: Attempt to remove an object that’s already been removed from the stage or whose parent/ancestor group has already been removed.

Have you found a resolution? [import]uid: 80890 topic_id: 17993 reply_id: 68795[/import]

Are you removing your localGroup in the clean function? [import]uid: 19626 topic_id: 17993 reply_id: 68796[/import]

i don’t have a clean function yet, in order to avoid something like this !! [import]uid: 96659 topic_id: 17993 reply_id: 68900[/import]

The reason I asked is I was putting the localGroup:removeSelf() in my clean functions and was getting a similar error. Took it out and the error went away, but if you don’t have a clean function… well in the infamous words of Emily Latilla (a Gilda Radner character from the original Saturday Night Live) “Never mind…”

I’ve figured out why mine is happening the Runtime:addEventListener( “collision”, onGlobalCollision ) is firing twice for the began process. Works fine the first time you play the level but the second time it will call it twice for the began to fire. I remove the event listener when the level is done so I’m not sure why it happens.

@weberkeith : … you’re right … i do the same ate mine now … and it works well
…
I removed the event Listener of the collision function at the action of the game over button
… and no errors occur when i play again and hit rocks … so the first eventListener is over with the first time played and the second one is working normal like the first one
…
thanks Buddy, :wink: [import]uid: 96659 topic_id: 17993 reply_id: 68926[/import]
