For loop 如何将圆的边对齐在一起？

如何将圆的边对齐在一起？框的边缘对齐，但我的圆周长/边缘不对齐，而是相互占据空间

    local areaPadding = 5
    local topPadding = 160
    local answerOffset = 6
    local area = answer_rect.width - (areaPadding*-5)
    local answerHeight = (area-topPadding-(answerOffset*#q.answers))/#q.answers
    local textX = numberX + 20
    local textW = _W - textX - 24

    local y = answer_rect.x + areaPadding + topPadding
    local howManyAnswers = #q.answers

--如有必要，请确保答案符合屏幕大小，降低答案高度 本地偏移=（_W-（多少人应答*（应答高度+应答偏移）-应答偏移））*0.5

结束

试试看

local _W = display.contentWidth
local _H = display.contentHeight

local areaPadding = 12
local topPadding = 16
local answerOffset = 30 -- you put in this space labels
local area = answer_rect.height - (areaPadding*2.5)
local howManyAnswers = #q.answers
local textX = numberX + 20
local textW = _W - textX - 24
local answerHeight = (area-topPadding-(answerOffset*#q.answers))/howManyAnswers 
local y = answer_rect.x + areaPadding + topPadding 
-- make sure answers fit screen size if neccessary decrease answerHeight
local offset = (_W - (howManyAnswers * (answerHeight+answerOffset))) * 0.5

for i=1, howManyAnswers do
  local rect = display.newRect(quizGroup, offset + answerOffset +(answerHeight+answerOffset)*(i-1), y, answerHeight, answerHeight)
  rect.anchorX, rect.anchorY = 0, 0
  rect.id = "answer"
  rect.index = i
  rect:setFillColor(0.1)
  rect:addEventListener("touch", buttonTouched)

  local label = display.newText({parent=quizGroup, text=i..".", font=native.systemFont, fontSize=20})
  label.x = rect.x - answerOffset * 0.5
  label.y = rect.y + 0.5 * rect.height 
  label:setFillColor(0.4)

  local answer = display.newText({parent=quizGroup, text=q.answers[i], width=textW, height=0, font=native.systemFont, fontSize=150})
  answer.x = rect.x + rect.width * 0.5
  answer.y = rect.y + rect.height * 0.5
  answer:setFillColor(1)
end

y是垂直轴，x是水平轴。只需使用x和宽度值，而不是y和高度值。这是简单的数学。。。来吧，我的y被指定为一个局部变量，我已经把它改成了x，但它仍然破坏了应用程序，我认为它是在变量的方程上…我非常感谢rect（shape）但是我的文本答案和文本编号标签没有对齐，因为我忘了放代码块，图像在上面…我添加了必要的代码来正确对齐标签和答案，所以一切都应该正常：）一些元素可能需要更小或更大才能看起来更好。天哪，你一定是上天派来的idurniat lol。。这两个框的位置是正确的，但最后一个框是空的。我试图添加显示的“answer.anchorX=0”，但它不合适。我将增加/减少您的值。非常感谢..您擅长数学..我如何调整矩形形状以适合屏幕边缘？还有，我怎样才能使它循环呢？newCircle（）可以工作，但会破坏应用程序。。请参见上图。这取决于你如何处理应用程序中的缩放。您可以在config.lua中找到scale设置，请在Corona上阅读更多有关它的信息。请注意，矩形实际上是正方形，边相等

answerHeight

。圆圈是如何破坏你的应用程序的？
