Question

确定。所以我正在编写一个Corona程序，在书中我按照所有说明创建了一个菜单并创建了一个新的游戏场景。问题是当我把代码放入模拟器或bluestacks android并按下图片没有任何反应时没有任何反应。没什么，跟帮助按钮一样。

我做错了什么？这是我的代码：

function loadGame(event)
if event.target.name == "playbutton" then
    transition.to(menuScreenGroup, {time = 0, alpha=0, onComplete = addGamescreen})
    playBtn:removeEventListener("tap", loadgame)
    end
end

function loadHelp(event)
if event.target.name == "helpbutton" then
    transition.to(menuScreenGroup, {time = 0, alpha=0, onComplete = addHelpScreen})
    helpBtn:removeEventListener("tap", loadHelp)
end
end

function addHelpScreen()
helpScreenGroup = display.newGroup()
helpScreen = display.newImage("helpScreen.png", 0, 0, true)
helpScreen.x = _W
helpScreen.y = _H

end

function addGameScreen()
background = display.newImage("bg.png", 0, 0, true)
background.x = _W
background.y = _Ys

paddle = display.newImage("paddle.png")
paddle.x = 160; paddle.y = 460;
paddle.name = "paddle"

ball = display.newImage("ball.png")
ball.x = 160; ball.y = 460;
ball.name = "ball"

scoreText = display.newText("Score:", 5, 2, "Arial", 14)
scoreText:setTextColor( 255, 255, 255, 255)
scoreNum = display.newText("0", 54, 2, "Arial", 14)
scoreNum:setTextColor( 255, 255, 255, 255)

levelText = display.newText("Level:", 420, 2, "Arial", 14)
levelText:setTextColor(255, 255, 255, 255)
levelNum = display.newText("1", 460, 2, "Arial", 14)
levelNum:setTextColor( 255, 255, 255, 255)

gameLevel1()

currentLevel = 1

bricks:toFront()
local numOfRows = 4
local numOfColumns = 4
local brickPlacement = {x = (_W) - (brickWidth * numOfColumns ) / 2 + 20, y = 50}
for row = 0, numOfRows - 1 do
local brick = display.newImage("brick.png")
brick.name = "brick"
brick.x = brickPlacement.x + (column * brickWidth)
brick.y = brickPlacement.y + (row * brickHeight)
physics.addBody(brick, "static", {density = 1, friction = 0, bounce = 0})
bricks.insert(bricks, brick)

end
end

function gameLevel2()
currentLevel = 2
bricks:toFront()
local numOfRows = 5
local numOfColumns = 8
local brickPlacement = {x = (_W) - (brickWidth * numOfColumns ) / 2 + 20, y = 50}
for row = 0, numOfRows -  1 do
for column = 0, numOfColumns - 1 do
-- Create a brick
local brick = display.newImage("brick.png")
brick.name = "brick"
brick.x = brickPlacement.x + (column * brickWidth)
brick.y = brickPlacement.y + (row * brickHeight)
physics.addBody(brick, "static", {density = 1, friction = 0, bounce = 0})
bricks.insert(bricks, brick)
end
end
end

Answer 1

检查以下代码行：

background.y = _Ys

我认为应该是：

background.y = _H

Answer 2

我没有看到你在哪里添加任何事件监听器来捕获触摸或点击。我看到你要删除点击处理程序的位置。

尝试做：

somegraphic：的addEventListener（ “抽头”，loadHelp）

我无法从你的代码中知道你需要将事件监听器附加到什么地方。

Answer 3

你能描述一下你想要什么吗？用addEventListener向我展示你的代码，并在所有的监听器中做一些打印。因此，您可以追踪确切问题的位置。
