Question

我的按钮在Corona SDK中出于某种原因不会出现在屏幕上这里是我的代码，我错过了什么？

local composer = require（“composer”）

local scene = composer.newScene（）

- 包括Corona的“小部件”库 local widget = require“widget”

- 处理按钮事件的功能本地函数handleButtonEvent（event）

if ( "ended" == event.phase ) then
    print( "Button was pressed and released" )
end

端

- 前瞻声明和其他本地人本地playBtn

- playBtn的'onRelease'事件监听器本地函数onPlayBtnRelease（）

-- go to levelSelect.lua scene
composer.gotoScene( "levelSelect", "fade", 500 )

return true -- indicates successful touch

端

- 背景 local sky = display.newImage（“startScreen / sky.png”） sky.x = display.contentWidth / 2; sky.y = display.contentHeight / 2;

- 图片 local preston = display.newImage（“startScreen / PrestonArt.png”）普雷斯顿：规模（0.4,0.4） preston.x = display.contentWidth / 2; preston.y = display.contentHeight / 2;

- 标签 local learningLabel = display.newImage（“startScreen / Learning.png”） learningLabel：scale（0.3,0.3） learningLabel.x = 506; learningLabel.y = 170;

local centerLabel = display.newImage（“startScreen / Center.png”） centerLabel：scale（0.3,0.3） centerLabel.x = 506; centerLabel.y = 600;

功能场景：创建（事件） local sceneGroup = self.view

-- Called when the scene's view does not exist.
-- 
-- INSERT code here to initialize the scene
-- e.g. add display objects to 'sceneGroup', add touch listeners, etc.

-- create a widget button (which will loads levelSelect.lua on release)
playBtn = widget.newButton{
    defaultFile = "startScreen/Play.png",       --the "default" image file
    overFile = "startScreen/Play-Over.png",     --the "over" image file 
    width=240, height=120,
    onRelease = onPlayBtnRelease    -- event listener function
}
playBtn.x = 300; playBtn.y = 695;

-- all display objects must be inserted into group
 sceneGroup:insert( playBtn )

端

功能场景：显示（事件） local sceneGroup = self.view local phase = event.phase

if phase == "will" then
    -- Called when the scene is still off screen and is about to move on screen
elseif phase == "did" then
    -- Called when the scene is now on screen
    -- 
    -- INSERT code here to make the scene come alive
    -- e.g. start timers, begin animation, play audio, etc.
end

端

功能场景：隐藏（事件） local sceneGroup = self.view local phase = event.phase

if event.phase == "will" then
    -- Called when the scene is on screen and is about to move off screen
    --
    -- INSERT code here to pause the scene
    -- e.g. stop timers, stop animation, unload sounds, etc.)
elseif phase == "did" then
    -- Called when the scene is now off screen
end

端

功能场景：破坏（事件） local sceneGroup = self.view

-- Called prior to the removal of scene's "view" (sceneGroup)
-- 
-- INSERT code here to cleanup the scene
-- e.g. remove display objects, remove touch listeners, save state, etc.

if playBtn then
    playBtn:removeSelf()    -- widgets must be manually removed
    playBtn = nil
end

端

- 监听器设置场景：addEventListener（“创建”，场景）场景：addEventListener（“show”，场景）场景：addEventListener（“隐藏”，场景）场景：addEventListener（“destroy”，场景）

返回场景

Answer 1

我的猜测是

评论说转到level1.lua但它尝试转到levelSelect
不要在文件名中使用大写（通常）
尝试删除＆＃34; fade＆＃34;，500以查看它是否有效
在levelselect.lua中，你没有返回场景或没有处理场景：创建

请提供更多代码和信息
