Method, device and readable storage medium for unit movement based on tile map

Abstract

The present invention relates to a method, device and readable storage medium for moving a unit based on a tile map. The method includes the steps of: rasterizing the map into a tile map, and marking whether each grid is passable; when the unit moves on the map , calculate the coordinates of the first collision point on the moving path; obtain whether the points around the coordinates of the collision point are passable, and then calculate the direction of the hypotenuse that the unit collides with; the unit moves along the hypotenuse: According to the coordinates of the collision point, the direction of the hypotenuse and the expected end coordinates, the actual end coordinates of the unit are calculated. The method proposed by the present invention is used to quickly calculate the moving collision logic scheme, which has the advantages of simplicity and high efficiency, and can also be used in frame synchronization games.

Description

technical field [0001] The present invention relates to the technical field of game character control, in particular to a tile map-based unit movement method, device and readable storage medium. Background technique [0002] Online games are individual multiplayer online games that use the Internet as the transmission medium, the game operator's server and the user's computer as the processing terminal, and the game client software as the information interaction window. When dealing with movement logic in a game based on Tile Map (tile map), the traditional method is to fix the character in the middle of the grid and jump a grid every time it moves, or it can only move freely in four directions. Stop moving when blocked. [0003] In the game, if free movement in all directions is required, a commercial 2D physics engine is generally used to deal with collisions. For frame synchronization games, since the computer cpus used by each player have different carry strategies in ...

AI Technical Summary

Problems solved by technology

For frame synchronization games, since the computer CPUs used by each player have different carry strategies in calculating floating-point numbers, it will lead to inconsistent calculations, and commercial physics engines cannot perform fixed-point number transformations by themselves.

Therefore, in games that use frame synchronization as the network synchronization scheme, it is impossible to use the physics engine to perform smooth movement of characters in the game with collision edges
