Abstract(in English) | In recent years, fighting games have been played all over the world, and through the use of the Internet, it is possible to play against people from many different countries. In the past, most fighting games used input delays to synchronize inputs, but recently a technology called rollback networking is being used to predict input. The current rollback networking prediction assumes that the remote player's most recent input continues during the communication delay. However, with this kind of prediction, as the communication delay increases, the correctness of the prediction will decrease, resulting in severe frame drops. Therefore, we propose a method to improve the rollback networking by improving the correctness of the prediction based on past input. In this study, we simulated the proposed method and conventional rollback networking, and compared the correctness of the prediction. The results show that the proposed method has a higher percentage of correct predictions than the conventional method. |
