أنا عندي سؤال أرجو الإجابة عنه : نفرض وجود سيارة لها أربع عجلات ومحرك (قوة دفع ) نرمزها EF كشعاع ونفرض أن الدفع خلفي كيف نحصل على موضع مركز السيارة و زاوية دورانها في كل لحظة أخذين بالحسبان دوران العجلات الأمامية حول محور عمودي على السيارة ؟
بدك تلاقي شي علاقة بتربط بين سرعة السيارة وزاوية دوران الدواليب الأمامية (وأنت بتحدد مدى ارتباط زاوية دوران المقود بزاوية دوران الدواليب الأمامية) بتحدد بهي العلاقة تسارع تغير زاوية مركز السيارة ابتداءً من زاويتها الابتدائية قبل دوران المقود وحتى مساواتها إلى زاوية الدواليب الأمامية . إذا ما لقيت هيك علاقة يمكن فيك تقدرها من عندك وتجرب لحتى تزبط حركة السيارة وتصير مشابهة لحركتها الحقيقية لأنو كمان بيدخل بهي العلاقة ثقل السيارة ، بس إذا بدك تجرب تجريب فطبعاً ما حتدخِّل ثقل السيارة .
عم تحكي 3D مو هيك ؟؟ والله حالياً كنت عم جرب بهيك شي بس ما كانت تظبط معي, عم تطلع السيارة كأنها ماشية عالجليد! هادا غير موضوع الـmodel اللي محاورو فايتين بالحيط شوف لقيت هاد: http://www.codeproject.com/KB/game/Simcars.aspx
لسا ما قريتو بس شفت التنفيذ تبعو حلو بس بدو شوية تظبيط خصوصي بموضوع الدوران , هادا غير أنو هون ما عم يحرك الدواليب بس عم يحرك السيارة
أنا آسف على التأخير بالرد سؤالي عن تصميم لعبة ولكن برأيي الأمر لا يختلف كثيراً لأن الألعاب الضخمة والقوية بالسوق تقوم بعملية محاكاة كاملة للسيارة وشكراً لاهتمامكم ولحسن ردودكم
