Corona раскадровка дает черное изображение

Question

Я создал меню с 2 кнопками, и я использую API-интерфейс раскадровки, чтобы перемещаться по сцене, но он работает только для первой кнопки, для другой кнопки он дает черный экран, я положительный нет ничего плохого в SCENE 2, потому что я попытался установить обе сцены (SCENE 1 и SCENE 2) того же кода, и он работал с SCENE 1, но все же дает черное изображение для SCENE 2, вот мой код меню, надеюсь, вы можете исправить ошибку:

local storyboard = require ("storyboard") 
local scene = storyboard.newScene() 


    function scene:createScene(event) 

local screenGroup = self.view 

background = display.newImage("start.png") 
background:setReferencePoint(display.BottomLeftReferencePoint) 
background.x = 0 
background.y = 320 
background.speed = 1 
screenGroup:insert(background) 

city2 = display.newImage("city2.png") 
city2:setReferencePoint(display.BottomLeftReferencePoint) 
city2.x = 0 
city2.y = 320 
screenGroup:insert(city2) 



play = display.newImage("play.png") 
play.x = 242 
play.y = 161 
screenGroup:insert(play) 

controls = display.newImage("controls.png") 
controls.x = 144 
controls.y = 201 
screenGroup:insert(controls) 



function SCENE1(event) 
if event.phase == "began" then 
    storyboard.gotoScene("SCENE1", "fade", 400) 
end 
end 

function SCENE2(event) 
if event.phase == "began" then 
    storyboard.gotoScene("SCENE2", "fade", 400) 
end 
end 

function scene:enterScene(event) 

play:addEventListener("touch", SCENE1) 
controls:addEventListener("touch", SCENE2) 
end 



function scene:exitScene(event) 
play:removeEventListener("touch", SCENE1) 
controls:removeEventListener("touch", SCENE2) 
end 

function scene:destroyScene(event) 

end

Answer 1

я Тхи nk проблема находится в scene:enterScene, вы пытаетесь снова и снова загружать свой городской объект, в то же время в вашем коде слишком много прослушивателей времени выполнения, которые он повторяет при вызове того же объекта. Вы создаете игру с прокруткой? если это так, вы можете попытаться увидеть эту ссылку о том, как создать боковую прокрутку с нуля. http://mobile.tutsplus.com/tutorials/corona/corona-sdk-create-a-side-scroller-from-scratch/ надеется, что это поможет
