项目结构是这样子的:
主场景代码是这样子的:
local MainScene = class("MainScene", function() return display.newScene("MainScene") end) function MainScene:ctor() self.layer = display.newLayer(); self:addChild(self.layer) self.item0 = ui.newTTFLabelMenuItem({text = "START", size = 64, align = ui.TEXT_ALIGN_CENTER, x = display.cx, y = display.cy + 50, listener = function() print("Start touched") nexScene = display.newScene("AnotherScene"); CCDirector:sharedDirector():replaceScene(CCTransitionFade:create(1, nexScene)) end}) self.item1 = ui.newTTFLabelMenuItem({text = "ABOUT", size = 64, align = ui.TEXT_ALIGN_CENTER, x=display.cx, y=display.cy, listener = function() print("About touched") end}) self.item2 = ui.newTTFLabelMenuItem({text = "EXIT", size = 64, align = ui.TEXT_ALIGN_CENTER, x=display.cx, y=display.cy-50, listener = function() print("Exit touched") game.exit() end}) self.menu = ui.newMenu({self.item0,self.item1,self.item2}) self.layer:addChild(self.menu) end function MainScene:onEnter() self.layer:setTouchEnabled(true) end function MainScene:onTouch(event, x, y) print(event) end function MainScene:onExit() end return MainScene
新场景代码是这样子的:
local AnotherScene = class("AnotherScene", function() return display.newScene("AnotherScene") end) function AnotherScene:ctor() print("Constructor of AnotherScene") end function AnotherScene:onEnter() print("Custom AnotherScene:onEnter") ui.newTTFLabel({text = "AnotherScene", size = 64, align = ui.TEXT_ALIGN_CENTER}) :pos(display.cx, display.cy) :addTo(self) end return AnotherScene
可是点击点击START之后进入的是一个黑色的新场景,DEBUG内容如下:
根本就没有打印AnotherScene.lua ctor()和onEnter()里面的提示内容。
经查验qucik cocos2dx源码,发现display.newScene("AnotherScene")新建了一个名为"AnotherScene"的CCScene,
而不是去取AnotherScene.lua,如下:
function display.newScene(name) local scene = CCSceneExtend.extend(CCScene:create()) scene.name = name or "<unknown-scene>" return scene end
于是将item0的listener的代码如下:
print("Start touched") local AnotherScene = require("../scripts/app/scenes/AnotherScene") nexScene = AnotherScene:new(); CCDirector:sharedDirector():replaceScene(CCTransitionFade:create(1, nexScene))
然后就正常了。
如下:
这也许就是脚本语言的便利与不便利之处了。
