lua - Corona going to previous scene results in black screen -

-

i've got problem delaying game milestone, in scene1 click menu button takes me menu when user wants play again click play button , should go previous scene when goes black screen. here code, main menu button in scene 1:

function scene:enterscene(event)   local group = self.view   function menubutton:touch( event ) if event.phase == "began"     storyboard.gotoscene( "menu", "slideright", 750 )     audio.play(click)     display.getcurrentstage():setfocus( event.target )     event.target.isfocus = true elseif event.target.isfocus     if event.phase == "moved"         print( "user has moved finger off button." )     elseif event.phase == "ended"         print( "user has switched main menu" )         display.getcurrentstage():setfocus( nil )         event.target.isfocus = false     end end return true

end

here play button on main menu:

function scene:enterscene(event) local group = self.view   local function onscenetouch( event )     if event.phase == "ended"        audio.play(click)        local previousscene = storyboard.getprevious()        if previousscene == nil        storyboard.gotoscene( "scene1", "slideleft", 750 ) else        storyboard.gotoscene(previousscene)         return true     end  end end

any ideas? getting no errors in simulator output.

edit: line of code stopped blank screen when placed on menu, images show up, background image button images etc nothing else.

local prior_scene = storyboard.getprevious() storyboard.purgescene( prior_scene )

try use tap listener instead of touch listener. don't see entire code think there problem.

main menu button in scene 1:

function scene:enterscene(event)      local group = self.view      local function onmenubuttontap( event )         audio.play(click)         storyboard.gotoscene( "menu", "slideright", 750 )         return true     end end

play button on main menu scene:

function scene:enterscene(event)     local group = self.view       local function onplaytap( event )         audio.play(click)         local previousscene = storyboard.getprevious()         if previousscene == nil             storyboard.gotoscene( "scene1", "slideleft", 750 )         else             storyboard.gotoscene(previousscene)         end         return true     end end

------------------------------------------------------------
new code:
------------------------------------------------------------
change in scene1.lua

function scene:exitscene(event)      local group = self.view     storyboard.destroyscene( "scene1" )  end

with this

function scene:exitscene(event)       local group = self.view  end

in menu.lua add this:

function scene:createscene( event )     local group = self.view      storyboard.purgescene( "scene1" ) end  scene:addeventlistener( "createscene", scene )

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey?
