Question

我正在编写将分数保存到“状态”表的代码，它会不断累积，直到到达结果页面。我使用该表是因为它表示表比使用'globals'更好。我在累积时遇到问题，因为当跳转到下一个场景时，scoreText会重置为0。

main.lua

display.setStatusBar( display.HiddenStatusBar )                 
local storyboard = require "storyboard"          
storyboard.state = {}
storyboard.state.score = 0                    
storyboard.gotoScene( "scene_splash" )

Question1.lua

local scoreText

function scene:enterScene(event)
...
    scoreText = display.newText( "0", 0, 0, native.systemFont, 32 )
    scoreText:setFillColor( 0,0, 0 )
    scoreText.x = 87
    scoreText.y = 28
    group:insert( scoreText ) 

if (event.other == balloons[1])  then
    scene.updateScore()
    print('Ball is colliding')
    balloon1.isVisible = false
    balloonText1.isVisible = false 
    audio.play(pop)
    storyboard.gotoScene("correctAnswer1", "fade", 1000)
end
end

function scene.updateScore()
   storyboard.state.score = storyboard.state.score + 50
   scoreText.text = storyboard.state.score
end

Question2.lua

local scoreText

function scene:enterScene(event)
...
if (event.other == balloons[3])  then
    scene.updateScore()
    print('Ball is colliding')
    balloon3.isVisible = false
    balloonText3.isVisible = false 
    audio.play(pop)
    storyboard.gotoScene("correctAnswer2", "fade", 1000)
end
end

function scene.updateScore()
   storyboard.state.score = storyboard.state.score + 50
   scoreText.text = storyboard.state.score
end

...

Answer 1

我在一行中犯了一个小错误，我将其改为：

scoreText = display.newText( storyboard.state.score, 0, 0, native.systemFont, 32 )

Answer 2

问题是enterScene事件没有other字段，因此event.other为nil，因此您调用score.update的代码块会不会在任何一个问题场景中执行。您可以通过在更新中添加一些print语句来检查这一点。条件应该是别的。
