了解Corona SDK中的场景

我对Corona来说是非常

在我的游戏中,我想要一个包含多个选项的菜单(例如“单人游戏”或“设置”)。当点击任何屏幕消失的选项时,会出现一个新选项。

下一个屏幕(例如,点击“单人游戏”之后)应该有一些文字,如“选择你的角色”,一旦用户点击他们的角色,另一个屏幕淡入等等。

我想知道我所谈论的内容是否被称为场景,如果不是,它们是什么以及它们是如何工作的?

请随意解释,或者如果它太多,请发布指向可理解来源的链接,例如另一个堆栈溢出问题或YouTube视频。

还有一件事是,是否可以让用户滑动屏幕,这会触发将他/她带回不同屏幕/场景的事件?

是的,您可以使用滑动事件触发屏幕分页。为此,请参阅此问题: How to slide pages in Corona SDK

电晕支持的当前场景管理器是作曲家(故事板已被弃用,将来将无法使用)

日冕场景由composer

管理和处理

以下是composer tutorial

的链接

每个场景都会响应以下事件:

  • create
  • show
  • hide
  • destroy

理解场景生命周期的关键,你需要记住create事件只被称为一次,直到场景被破坏。

事件show每次调用场景

时都会调用

事件hide被称为 eveytime ,场景被驳回。

仅当操作系统决定摆脱该场景的内存时才会调用事件destroy。在您退出应用之前,这可能不会发生。

是的,所有计划都可以通过场景来完成,适用于组织游戏。

对于每个场景,您都可以在this page结尾处遵循此推荐格式。我会在这个答案结尾处输入它。

一旦你有了场景,你可以用以下方式打电话给他们:

storyboard.gotoScene("name_Of_The_Scene")

并删除场景

storyboard.purgeScene("name_Of_The_Scene")

我认为您可以使用电晕的触摸事件来实现滑动效果(它们非常易于使用)。在我的情况下,我在场景之间使用具有过渡效果的按钮。

场景的推荐格式

(用于复制和粘贴)

local storyboard = require( "storyboard" )
local scene = storyboard.newScene()

----------------------------------------------------------------------------------
-- 
--      NOTE:
--      
--      Code outside of listener functions (below) will only be executed once,
--      unless storyboard.removeScene() is called.
-- 
---------------------------------------------------------------------------------


-- local forward references should go here --


---------------------------------------------------------------------------------
-- BEGINNING OF YOUR IMPLEMENTATION
---------------------------------------------------------------------------------

-- Called when the scene's view does not exist:
function scene:createScene( event )
        local group = self.view

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

    --      CREATE display objects and add them to 'group' here.
    --      Example use-case: Restore 'group' from previously saved state.

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

end


-- Called BEFORE scene has moved onscreen:
function scene:willEnterScene( event )
       local group = self.view

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

     --      This event requires build 2012.782 or later.

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

end


-- Called immediately after scene has moved onscreen:
function scene:enterScene( event )
        local group = self.view

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

        --      INSERT code here (e.g. start timers, load audio, start listeners, etc.)

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

 end


 -- Called when scene is about to move offscreen:
 function scene:exitScene( event )
         local group = self.view

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

         --      INSERT code here (e.g. stop timers, remove listeners, unload     sounds,etc.)

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

 end


-- Called AFTER scene has finished moving offscreen:
function scene:didExitScene( event )
        local group = self.view

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

    --      This event requires build 2012.782 or later.

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

 end


 -- Called prior to the removal of scene's "view" (display group)
  function scene:destroyScene( event )
         local group = self.view

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

         --      INSERT code here (e.g. remove listeners, widgets, save state, etc.)

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

 end


-- Called if/when overlay scene is displayed via storyboard.showOverlay()
 function scene:overlayBegan( event )
         local group = self.view
         local overlay_name = event.sceneName  -- name of the overlay scene

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

         --      This event requires build 2012.797 or later.

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

 end


 -- Called if/when overlay scene is hidden/removed via storyboard.hideOverlay()
  function scene:overlayEnded( event )
         local group = self.view
         local overlay_name = event.sceneName  -- name of the overlay scene

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

         --      This event requires build 2012.797 or later.

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

 -- "createScene" event is dispatched if scene's view does not exist
  scene:addEventListener( "createScene", scene )

  -- "willEnterScene" event is dispatched before scene transition begins
  scene:addEventListener( "willEnterScene", scene )

 -- "enterScene" event is dispatched whenever scene transition has finished
  scene:addEventListener( "enterScene", scene )

  -- "exitScene" event is dispatched before next scene's transition begins
  scene:addEventListener( "exitScene", scene )

  -- "didExitScene" event is dispatched after scene has finished transitioning out
  scene:addEventListener( "didExitScene", scene )

 -- "destroyScene" event is dispatched before view is unloaded, which can be
  -- automatically unloaded in low memory situations, or explicitly via a call to
  -- storyboard.purgeScene() or storyboard.removeScene().
  scene:addEventListener( "destroyScene", scene )

 -- "overlayBegan" event is dispatched when an overlay scene is shown
 scene:addEventListener( "overlayBegan", scene )

 -- "overlayEnded" event is dispatched when an overlay scene is hidden/removed
 scene:addEventListener( "overlayEnded", scene )

您还可以尝试一个名为Director类的流行第三方场景管理器。它没有内置在Corona中,但是学习起来有点简单。
