LUA：シーンが作成されていません。なにが問題ですか？

Question

私はスタート画面を持っているゲームを構築しています。スタートボタンをクリックすると、最初のレベルになります。いくつかのことが起こり、その後私は2番目のレベルに移動します。

しかし、私は問題に遭遇しており、解決策を見つけることができないようです。 私はスタートボタンをクリックすると、何かをプリントアウトするので、作成機能に詰まっているようです。私はあなたが作成機能に何かを配置する必要はなく、すべてをSHOW FUNCTIONに置く必要があると言われました。私は誤解しましたか？

START SCENE

local composer = require("composer") 
local widget = require("widget") 

local options = {effect = "fade", time = 800} 
local startBtn; 

local function start(event) 
    -- load first scene 
    composer.gotoScene("level1", options); 
    startBtn:removeSelf(); 
    print("Start Game") 
end 

startBtn = widget.newButton(
    { 
    left = 75, 
    top = 100, 
    id = "startBtn", 
    label = "Start", 
    onEvent = start 
    } 
) 

私はそれがここに であると私は問題に実行しているところである最初のレベルに私を取る必要がありSTART]ボタンをクリックしてください。それが正しい名前で追加されていなかったため

scene:addEventListener("create", scene) 
scene:addEventListener("enter", scene) 
scene:addEventListener("hide", scene) 

return scene 

Answer 1

さて、あなたはscene:addEventListener("show", scene)あるべきリスナーscene:addEventListener("enter", scene)を追加する（変更を示すために入力します）

あなたのリスナーであっても、解雇されていません。

Composerは、次のイベントを使用します。create, destroy, show, hide。
