Like in other areas, the use of artificial intelligence (AI) is spreading among computer games, which has become a huge industry. In most of the games, artificial intelligence enables the game characters to move, make decisions about where to move and generate tactical and strategic thinking capability. In this study, a game using artificial intelligence has been developed for mobile device platform. Stimulation of rational movements in game characters was worked on by using an advanced form of AI. To enable this, Simple Reflex Agents method was adopted. With a dynamic programming strategy approach, a goal finding algorithm was used to develop a Goal Based Agents method. It has been observed that movements of the goal based characters became more realistic, owing to their goal focused movements. The evaluation of the test results has shown that the intended result has been accomplished relying on this method

AKILLI ETMENLER İLE IZGARA TABANLI BİR MOBİL OYUNDA YOL BULMA

Öz

Büyük bir endüstri haline gelen oyun alanında, her alanda olduğu gibi yapay zekânın kullanımı yaygınlaşmaktadır. Oyunlar da bulunan yapay zekâ oyuna karakterleri hareket ettirme, nereye hareket etmesi gerektiğine karar verme ve taktiksel veya stratejik düşünme yeteneğini kazandırmak için kullanılmaktadır. Bu çalışmada; mobil platformda yapay zekâ kullanan bir oyun geliştirilmiştir. Geliştirilen yapay zekâ ile oyunda yer alan yapay karakterlere, mantıklı bir şekilde hareket edebilme özelliğinin verilmesi üzerine çalışılmıştır. Bunu sağlayabilmek için ilk olarak basit refleks etmeni yöntemi kullanılmıştır. Dinamik programlama yaklaşımıyla bir yol bulma algoritması kullanılarak hedef tabanlı etmen yöntemi geliştirilmiştir. Geliştirilen yöntemde hedef tabanlı oyuncuların hedefe odaklı hareket etmelerinden dolayı, hareketlerinin daha gerçekçi olduğu tespit edilmiştir. Yapılan test sonuçları değerlendirildiğinde, geliştirilen yöntem ile istenilen sonuca ulaşıldığı görülmüştür
