The invention discloses a method, a device and a
system for realizing dynamic blocking in a three-dimensional
role playing game. The method comprises the following steps of: setting areas required to be dynamically blocked in a projected two-dimensional game scene in advance, establishing a mapping relationship table between each set dynamically blocked area identifier and a corresponding blocking type, storing the mapping relationship table in a file, distributing the file to a
server and a
client, storing the mapping relationship table by the
client, and establishing a mapping relationship between a three-dimensional game scene and the two-dimensional game scene; when the next found dynamically blocked area comprises a game event, acquiring a dynamically blocked area identifier corresponding to the game event; updating the established mapping relationship table according to blocking type information which carries the dynamically blocked area identifier and is returned from the
server; and determining a game path according to the updated mapping relationship table, and acquiring a game operation strategy corresponding to the blocking type of the dynamically blocked area identifier for operation according to the determined game path. By the method, the device and the
system, the user cost can be lowered, and the synchronization efficiency can be improved.
