High-precision synchronous prediction rollback method based on certainty

Abstract

The invention relates to a high-precision synchronous prediction rollback method and system based on certainty, when a client generates a user instruction, the user instruction is sent to a server for processing, and at the same time, the client carries out the following processing of step 1, allowing the client to carry out framing processing on the user instruction to obtain prediction frame instructions; step 2, for each prediction frame instruction, performing the following processing: performing calculation according to the prediction frame instruction and a world state of a previous frame to obtain a current prediction world state; and step 3, when the client receives the Nth authoritative frame instruction sent by the server, rolling back to the (N-1) th frame world state, and then calculating the Nth frame world state according to the Nth authoritative frame instruction and the (N-1) th frame world state; and repeating the steps 2-3 on the basis of the world state of the Nth frame. According to the method, the problem of game response delay caused by high time delay and high jitter characteristics of the network can be relieved to a great extent.

Description

technical field [0001] The invention relates to the technical field of online games, in particular to a deterministic-based high-precision synchronous prediction rollback method. Background technique [0002] Online game is a real-time and interactive software product with multiplayer online. Each player experiences the game by operating a game client. Transmission is used to achieve data synchronization between clients, so as to achieve a consistent game experience on different clients. [0003] A feature of online games is that they rely on network transmission. The player generates instructions through the input device of the client, and the instructions need and must be transmitted to the server through the network. After verification and calculation, the server will generate new instructions and return them to the client. Feedback for player input commands. In online games, the time from the generation of the command to the effective of the command is called the comm...
