lua - 在电晕中重新加载屏幕

Question

我正在电晕中开发一个应用程序，我需要一次又一次地重新加载同一个屏幕。我不知道该怎么做，任何人都可以用代码解释一下

Answer 1

1) director class

2) main.lua

display.setStatusBar (display.HiddenStatusBar)
--> Hides the status bar

local director = require ("director")
--> Imports director

local mainGroup = display.newGroup()
--> Creates a main group

local function main()
--> Adds main function

    mainGroup:insert(director.directorView)
    --> Adds the group from director

    director:changeScene("myscene")
    --> Change the scene, no effects

    return true
end

main()

3) myscene.lua

module(..., package.seeall)

function new()
    local localGroup = display.newGroup()

    local redbutton = display.newImage ("redbutton.png")
    redbutton.x = 160
    redbutton.y = 100
    localGroup:insert(redbutton)

    local function pressRed (event)
        if event.phase == "ended" then
            director:changeScene ("reloader")
        end
    end

    redbutton:addEventListener ("touch", pressRed)

    return localGroup
end

4) reloader.lua

module(..., package.seeall)

function new()
    local localGroup = display.newGroup()

        local function listener( event )
            director:changeScene ("myscene", "fade")
        end

        timer.performWithDelay(50, listener )

        return localGroup
end
