android - 降低速度值 LUA

Question

如何通过减少 star1.movementSpeed = 10000; 来增加 movementSpeed，每个 -1 10 秒。

我已经试过了，但不知道我做错了什么

function initStar()
local star1 = {}
star1.imgpath = "Star1.png"; --Set Image Path for Star
star1.movementSpeed = 10000; --Determines the movement speed of star
table.insert(starTable, star1); --Insert Star into starTable
end --END initStar()    


 local function star1incr() -- increments Speed value every time it is called
 movementSpeed = movementSpeed - 1
 star1.movementSpeed = "movementSpeed: " .. movementSpeed 
 end

 timer.performWithDelay(10000, star1incr, 0)

Answer 1

通过使用修复

   local function star1incr()
        starTable[1].movementSpeed = starTable[1].movementSpeed - 1
        print( "- 1" )
    end
