Corona SDK сцены игры

Question

Я просмотрел много других вопросов и руководств, но, к сожалению, безрезультатно. Я пытаюсь перейти от scene1 к scene2 с прослушивателем событий, и я копирую код, который был указан в проекте. Единственное различие между моей кнопкой и рабочей состоит в том, что я объявляю свое в файле lua и его не существует в scene1.ccscene Должен ли я помещать изображение в качестве объекта в scene1.csscene, чтобы использовать его как кнопка?

код Стараюсь:

local composer = require("composer") 

local scene = composer.newScene() 

-- ----------------------------------------------------------------------------------------------------------------- 
-- All code outside of the listener functions will only be executed ONCE unless "composer.removeScene()" is called. 
-- ----------------------------------------------------------------------------------------------------------------- 

-- local forward references should go here 
local start_button = display.newImage("START.png") --start button 

-- ------------------------------------------------------------------------------- 


-- "scene:create()" 
function scene:create(event) 

    local sceneGroup = self.view 

    -- Initialize the scene here. 
    -- Example: add display objects to "sceneGroup", add touch listeners, etc. 
    start_button.x=200 
    start_button.y=150 
end 


-- "scene:show()" 
function scene:show(event) 

    local sceneGroup = self.view 
    local phase = event.phase 

    if (phase == "will") then 
     -- Called when the scene is still off screen (but is about to come on screen). 
    elseif (phase == "did") then 
     -- Called when the scene is now on screen. 
     -- Insert code here to make the scene come alive. 
     -- Example: start timers, begin animation, play audio, etc. 
     function nextScene:touch (event) 
       local phase = event.phase 
       if "ended" == phase then 
        composer.gotoScene("scene2", { effect = "fade", time = 300 }) 
       end 
      end 
     start_button:addEventListener("touch", nextScene) 
    end 
end 


-- "scene:hide()" 
function scene:hide(event) 

    local sceneGroup = self.view 
    local phase = event.phase 

    if (phase == "will") then 
     -- Called when the scene is on screen (but is about to go off screen). 
     -- Insert code here to "pause" the scene. 
     -- Example: stop timers, stop animation, stop audio, etc. 
    elseif (phase == "did") then 
     -- Called immediately after scene goes off screen. 
     if nextSceneButton then 
      start_button:removeEventListener("touch", nextScene) 
     end 
    end 
end 


-- "scene:destroy()" 
function scene:destroy(event) 

    local sceneGroup = self.view 

    -- Called prior to the removal of scene's view ("sceneGroup"). 
    -- Insert code here to clean up the scene. 
    -- Example: remove display objects, save state, etc. 
end

scene:addEventListener("create", scene) 
scene:addEventListener("show", scene) 
scene:addEventListener("hide", scene) 
scene:addEventListener("destroy", scene)

Answer 1

Расширение файлов сцены должно быть «.lua» в Короне. Я думаю, что «csscene» имеет какое-то отношение к Какао.

Код ниже будет работать.

Примечания:

• Убедитесь, что файлы заканчивается .lua (main.lua, scene1.lua, scene2.lua).
• start_button теперь прямоугольник, но вы можете легко изменить его на изображение.
• start_button добавлен в группу sceneGroup. Это группа, которую будет использовать сцена, т. Е. При смене сцены все объекты в сцене будут обрабатываться надлежащим образом.
• добавляю eventListener по-другому, пожалуйста, прочитайте документацию для получения дополнительной информации: https://docs.coronalabs.com/api/event/touch/index.html

main.lua:

local composer = require("composer") 
composer.gotoScene("scene1") 

scene1.lua:

local composer = require("composer") 

local scene = composer.newScene() 

-- VARIABLES 
local start_button 

-- EVENTS 
local function onTouchStartButton(event) 
    if event.phase == "ended" then 
     composer.gotoScene("scene2") 
    end 
end 

function scene:create(event) 
    local sceneGroup = self.view 

    -- Create the start_button 
    start_button = display.newRect(100, 100, 100, 100) 

    -- Make sure you insert the button into the sceneGroup 
    sceneGroup:insert(start_button) 

    -- Set position of start_button 
    start_button.x=200 
    start_button.y=150 

    -- Add the event listener in the "create" stage instead of the show state 
    -- Now the start_button is in the scene_group so there is no need to remove 
    -- the touch listener under the "destroy" stag 
    start_button:addEventListener("touch", onTouchStartButton) 
end 


-- "scene:show()" 
function scene:show(event) 

    local sceneGroup = self.view 
    local phase = event.phase 

    if (phase == "will") then 
     -- Called when the scene is still off screen (but is about to come on screen). 
    elseif (phase == "did") then 
     -- Called when the scene is now on screen. 
     -- Insert code here to make the scene come alive. 
     -- Example: start timers, begin animation, play audio, etc. 
    end 
end 


-- "scene:hide()" 
function scene:hide(event) 

    local sceneGroup = self.view 
    local phase = event.phase 

    if (phase == "will") then 
     -- Called when the scene is on screen (but is about to go off screen). 
     -- Insert code here to "pause" the scene. 
     -- Example: stop timers, stop animation, stop audio, etc. 
    elseif (phase == "did") then 
    end 
end 


-- "scene:destroy()" 
function scene:destroy(event) 

    local sceneGroup = self.view 

    -- Called prior to the removal of scene's view ("sceneGroup"). 
    -- Insert code here to clean up the scene. 
    -- Example: remove display objects, save state, etc. 
end
