如何更新高分

Question

我的游戏在碰撞中有分数和高分属性所以每当我的对象在某个逻辑分数上碰撞时，高分会增加，因为我的游戏中还没有死亡阶段，所以当我重新启动我的游戏高分从零开始我希望高分应该从以前的高分开始，并且只有在得分>高分时才会更新。我已经为它写了代码但是当我的对象碰撞时它不起作用高分从 6 所以请告诉我解决它的方法

   local Highscore = 0
    score = 0
    local function updateText()
        HighscoreText.text = "Highscore: " .. Highscore
    end

-- collision Property --

 local function onCollision( event )
    if ( event.phase == "began" ) then
-- logic --

    -- score update--

-- highscore update--
if score > Highscore then
  Highscore = score 
end
updateText()


end
end
end

Runtime:addEventListener( "collision" , onCollision )

end

我使用 Corona SDK JSON 库创建了一个小模块来处理持久性以获得高分。

-- File name
local fileName = "highscore.json"
-- Path for File
-- The system.DocumentsDirectory will be backed up by synchronization in iOS
local pathForFile = system.pathForFile(fileName, system.DocumentsDirectory)

-- JSON library included in Corona SDK
local json = require( "json" )

-- This table holds two functions
-- persistHighscore, to save the highscore to file
-- fetchHighscore, to retrieve the saved highscore
local persistence = {}

-- Persists the highscore table
-- It receives only one parameter which must be a table
-- containing the highscore in a Key, Value pair
-- Example: {highscore = 10}
persistence.persistHighscore = function(highscoreTable)
    local encoded = json.encode( highscoreTable )
    local file, errorString = io.open( pathForFile, "w" )

    if not file then
        print("Opening file failed: " .. errorString)
    else
        file:write(encoded)
        file:flush()
        file:close()
    end
end

-- Returns the Highscore table
-- If there is a highscore file it will be read and a 
--table containing the highscore will be returned
persistence.fetchHighscore = function()
    local decoded, pos, msg = json.decodeFile( pathForFile )
    if not decoded then
        print( "Decode failed at "..tostring(pos)..": "..tostring(msg) )
    else
        print( "File successfully decoded!" )
        return decoded
    end
end

return persistence

在您的项目中：

local persistence = require("highscorePeristence")

如果您不熟悉使用 Lua 在 Corona SDK 中加载模块，请务必检查这个： Corona SDK API Doc - require 在你的高分处理逻辑中，当你发现分数高于当前高分时：

if score > highscore then
    -- Container table to be stored in JSON
    local scoreTable = {
        highscore=score
        }
    persistence.persistHighscore(scoreTable)
end

当您加载项目并且想要加载存储的高分时：

local highscore
local scoreTable = persistence.fetchHighscore()
-- No highscore was stored
if not scoreTable then
    -- Initialize the highscore with 0 since there was no other value before
    highscore = 0
else
    -- Initialize the highscore with the value read from the JSON decoded table
    highscore = scoreTable.highscore
end
