Description of the invention (2) The content of the game is monotonous and lacks expansibility: when the user plays the game again, the content of the game is simply repetitive and lacks novelty. In other words, if a game requires a map (such as a labyrinth in the game), the typical method is to set a map in advance during program design, and call the map to make the game run smoothly. This reduces the game's playability (that is, the game loses its original challenge after the user passes all the levels). In addition, some games use random methods to generate the required maps. Although this can improve the degree of change and fun of the game, the problems such as poor operability and simple maps will also greatly affect To reduce the user's desire to challenge the game. [Problems to be solved by the invention] Traditional games, due to the memory limitation of the carrier (such as the aforementioned portable data processor), its content is relatively monotonous and lacks expandability. Users often only repeat the same control procedures. Over time, it loses its freshness and challenge. Even the more changeable people only generate the required scenes (such as maps; or the appearance time of people and conditions) in a random manner, but they also have poor operability. Or a monotonous question. [Summary of the Invention] The main purpose of the present invention is to enable the game to dynamically update its game content (such as map data) through the network, and play games with other users through the network to enrich the game. Content, and make the game challenging. The device for extracting network resources through the network of the present invention is configured in a portable data processor (such as: Η P C, P D A), and is mainly processed by a central processing unit.
