円の端を合わせるにはどうすればいいですか？

Question

円の端をどのように揃えるには？ ..

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 

ボックスのエッジが整列しているが、私の円の円周/エッジが揃わないが、その代わりに、彼らはお互いのスペースを占有する - 必ず答えにフィット画面サイズを作るneccessary減少が ローカルオフセット=（_WをanswerHeight場合 - （howManyAnswers *（answerHeight + answerOffset） - answerOffset））* 0.5

for i=1, howManyAnswers do 
     local rect = display.newCircle(quizGroup, offset + (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 answer = display.newText({parent=quizGroup, text=q.answers[i], width=textW, height=0, font=native.systemFont, fontSize=150}) 
     answer.x = rect.x + rect.width * 0.3 
     answer.y = rect.y + rect.height * 0.5 
     answer.anchorX = 0 
     answer:setFillColor(1) 
    end 
end

Answer 1

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
