Oncomplete its not working in my transition

Question

I have this transition. I want to make a image that is in the block in position "desplazar" dissapear and then delete it.

transition.to(block[desplazar], {time=14000, alpha=0, onComplete=timer.performWithDelay(12000, borrado(desplazar),1) })

local function borrado(desplazar)
    block[desplazar]:removeSelf()
end    

But i'ts not working, the image is dissapearing inmediatly and i think the image is going to to dissapear when the transition is complete, also i have put a delay in the function but it`s not working.

Hope you can help me

Thanks

I made it this way also

transition.to(block[desplazar], {time=14000, alpha=0, onComplete=timer.performWithDelay(12000, intime(),1) })

local function intime()
    print ("intime")
    borrado(desplazar)
end 

Answer 1

this code will work

    local function borrado(desplazar)
        block[desplazar]:removeSelf()
    end 


transition.to(block[desplazar], {time=14000, alpha=0, onComplete = timer.performWithDelay(12000, function() borrado(desplazar) end),1})

just remember when using transition and timer do not just call the function with an argument because you will not achieve the time you want it to trigger just like this

 timer.performWithDelay(12000, borrado(desplazar)) 

it will just trigger the function without the time you assign. hope this helps

Answer 2

Corona SDK onComplete parameters expect a function as the parameter, not the results of a function call. You cannot call another function directly as in the:

 onComplete = timer.performWithDelay(12000....) 

example.

The best way is to create a function that does the work you want to do when complete:

 local function handleOnComplete(target)
     target:removeSelf()
     target = nil
 end
 transition.to(block[desplazar], {time=14000, alpha=0, onComplete=handleOnComplete } )

The handleOnComplete gets a parameter passed to it which is the object that was transitioning. I don't understand why you want to wait another 12 seconds after the transition is complete to actually remove it. If that's important, you can put a timer in handleOnComplete() to delay the removal a bit.

Answer 3

You are passing the result of calling borrado(desplazar) to timer.performWithDelay. You need to pass a function to performWithDelay which will call borrado(desplazar) when the timer calls the passed function.

Answer 4

This will work:

transition.to(block[desplazar], {time=14000, alpha=0, onComplete=function()
    timer.performWithDelay(12000, borrado(desplazar),1)
end })

local function borrado(desplazar)
    block[desplazar]:removeSelf()
end
