hello i am trying to restart my game via composer ,when game scene is changed to restart.lua it gives me this error “game.lua:54:attempt to call method ‘insert’ (a nil value)”

game.lua;

your

timer.performWithDelay( 2000, rastgelespwn(),-1)

is looping.

You need to cancel or pause this timer when going to other scene.

I did a quick google translate( turkish)

this should go at the top

local benimZamanlayıcı&nbsp;

–replace other timer with this

benimZamanlayıcı=timer.performWithDelay( 2000, rastgelespwn(),-1)&nbsp;

– in scene hide (will event)

if benimZamanlayıcı then timer.pause(benimZamanlayıcı) end&nbsp;

–in scene show (did event)

if benimZamanlayıcı then timer.resume(benimZamanlayıcı) end

–in scene destroy

if benimZamanlayıcı then timer.stop(benimZamanlayıcı) end

You probably want to put i instead of ı

I’ve had this same problem come up twice this week. You are adding touch and tap handlers to “Runtime”. Please do not do this. It causes problems with scenes being re-entered at weird times.

If you want to the full screen touchable please create a full screen display.newRect(), hide it, make it hit testable, layer it just above the background (needs to be the back most touchable item) and add your listeners to that object:

local backgroundTouchBox = display.newRect( display.contentCenterX, display.contentCenterY, display.actualContentWidth, display.actualContentHeight )

sceneGroup:insert( backgroundTouchBox )

backgroundTouchBox.isVisible = false

backgroundTouchBox.isHitTestable = true

backgroundTouchBox:addEventListener( “touch”, yourTouchFunction )

While adding touch handlers to Runtime might work in simple circumstances, its not working with Composer.

Thanks for all of your answers.I tried what you guys said but it didnt worked well i just removed the onComplete=rastgelespwn in the ;

transition.to( enemy, {time=math.random(500,2500),x=don,y=2020,print("ilk "..don),onComplete=rastgelespwn} )

it worked that way but now its only spawning one enemy in the game scene and i need to make it spawn until a collision or until changing the scene.

cemaymelek · July 16, 2016, 11:30am

I just solved it by just simply removing the “()” in the

zaman = timer.performWithDelay( 2000, rastgelespwn(),-1)

and making it look like this;

zaman = timer.performWithDelay( 2000, rastgelespwn,-1)
