Hi, I’m using this score system from tutorial by peach pellen:
( http://techority.com/2011/01/26/how-to-add-a-score-to-your-iphone-app/ )
-- A sample score keeping display
-- This updates a display for a numeric score
-- Example usage:
-- Place the score at 50,50
-- score.init( { x = 50, y = 50 } )
-- Update the score to current value + 10:
-- score.setScore( score.getScore() + 10 )
module(..., package.seeall)
-- Init images. This creates a map of characters to the names of their corresponding images.
local numbers = {
[string.byte("0")] = "0.png",
[string.byte("1")] = "1.png",
[string.byte("2")] = "2.png",
[string.byte("3")] = "3.png",
[string.byte("4")] = "4.png",
[string.byte("5")] = "5.png",
[string.byte("6")] = "6.png",
[string.byte("7")] = "7.png",
[string.byte("8")] = "8.png",
[string.byte("9")] = "9.png",
[string.byte(" ")] = "space.png",
}
-- score components
local theScoreGroup = display.newGroup()
local theBackground = display.newImage( "scorebg.png" )
local theBackgroundBorder = 10
theScoreGroup:insert( theBackground )
local numbersGroup = display.newGroup()
theScoreGroup:insert( numbersGroup )
-- the current score
local theScore = 0
-- the location of the score image
-- initialize the score
-- params.x \<= X location of the score
-- params.y \<= Y location of the score
function init( params )
theScoreGroup.x = params.x
theScoreGroup.y = params.y
setScore( 0 )
end
-- retrieve score panel info
-- result.x \<= current panel x
-- result.y \<= current panel y
-- result.xmax \<= current panel x max
-- result.ymax \<= current panel y max
-- result.contentWidth \<= panel width
-- result.contentHeight \<= panel height
-- result.score \<= current score
function getInfo()
return {
x = theScoreGroup.x,
y = theScoreGroup.y,
xmax = theScoreGroup.x + theScoreGroup.contentWidth,
ymax = theScoreGroup.y + theScoreGroup.contentHeight,
contentWidth = theScoreGroup.contentWidth,
contentHeight = theScoreGroup.contentHeight,
score = theScore
}
end
-- update display of the current score.
-- this is called by setScore, so normally this should not be called
function update()
-- remove old numerals
theScoreGroup:remove(2)
local numbersGroup = display.newGroup()
theScoreGroup:insert( numbersGroup )
-- go through the score, right to left
local scoreStr = tostring( theScore )
local scoreLen = string.len( scoreStr )
local i = scoreLen
-- starting location is on the right. notice the digits will be centered on the background
local x = theScoreGroup.contentWidth - theBackgroundBorder
local y = theScoreGroup.contentHeight / 2
while i \> 0 do
-- fetch the digit
local c = string.byte( scoreStr, i )
local digitPath = numbers[c]
local characterImage = display.newImage( digitPath )
-- put it in the score group
numbersGroup:insert( characterImage )
-- place the digit
characterImage.x = x - characterImage.width / 2
characterImage.y = y
x = x - characterImage.width
--
i = i - 1
end
end
-- get current score
function getScore()
return theScore
end
-- set score to value
-- score \<= score value
function setScore( score )
theScore = score
update()
end I’m trying to optimize this for retina for a long time…
For others images I’m using display.neImageRect with this in config.lua
application =
{
content =
{
width = 320,
height = 480,
scale = "letterbox",
imageSuffix =
{
["@2x"] = 2,
}
},
} Is there anyone who using this and optimized it for retina? Or can you please help me optimize it?
