プログラミング初心者ですが、試行錯誤しながら楽しくコロナを学んでいます（ほとんどが間違い！）

私は大学のプロジェクト用に航空交通管制シミュレーションの作成に取り組んでおり、オブジェクト (レーダー上の飛行機) を回転させてタップ ポイントに移動させる方法についてレンガの壁にぶつかりました。

次のコードを使用して飛行機を動かしています。

local function moveAirplane1(event)

function cleanAirplaneRuntime()
Runtime:removeEventListener("enterFrame", moveAirplane1)
end

if Airplane1OnRadar == false then
cleanEI137Runtime()
end

Airplane1.x = Airplane1.x + math.cos(math.rad(Airplane1.rotation)) * Airplane1SPEED
Airplane1.y = Airplane1.y + math.sin(math.rad(Airplane1.rotation)) * Airplane1SPEED


end
Runtime:addEventListener("enterFrame", moveAirplane1)

これは問題なく動作し、plane.rotation の値を加算または減算することで方向を制御できます。ただし、私がやりたいことは、プレイヤーが画面をタップして飛行機を回転させ、その地点まで移動できるようにすることです。

私はタップポイントと飛行機の間の角度を計算し、その差で航空機を回転させようとしましたが、飛行機がどの象限にあるか、およびタップポイントが飛行機に対してどの象限にあるかに応じて、非常に多くの順列があります。私は正しい軌道に乗っているのか、それとも行方不明になっている簡単な方法があるのか​​ 疑問に思っていますか?

これが私が試してきたことです（申し訳ありませんが、長くなりました）

function vectorTo()


    function setVectorPoint(event)

        vectorPoint = display.newCircle(0, 0, 5)
        vectorPoint.x = event.x
        vectorPoint.y = event.y
        vectorPoint.alpha = 0.5

        airplane = EI159
        vP = vectorPoint
        airplaneHdg = EI159CurrentHeading

        Runtime:removeEventListener("tap", setVectorPoint)


        function angleBetween(vP, airplane )                -- Calculate angle between airplane and tap point

        airplane = Airplane1
        vP = vectorPoint

        xDist = airplane.x - vP.x 
        yDist = airplane.y - vP.y

        angleBetween = math.deg( math.atan( yDist/xDist ) )

            return angleBetween

        end

        return math.floor(angleBetween*math.pow(10,0)+0.5) / math.pow(10,0)
