100 در 100
جوفتمون میگیم چرا آچار گریبکس
دقیقا مشکل اصلی من هم تو عنوان تاپیک هست
خودم یه کدی با XNA پیدا کردم با کمی تغییرات 40 هزار خطو به راحتی رسم میکنه فقط نتونستم حرکتش بدم که ببینم خوب هست یا نه

اینم لینک کد اصلی برای رسم خط در XNA : لینک (http://msdn.microsoft.com/en-us/library/bb196414.aspx)
کسی می تونه تغییراتی تو کد بده که به حرکت در بیاد ؟
کسی راه دیگری یا زبان دیگری رو پیشنهاد می کنه ؟ لطفا با کد
