Provided is a method and system for integrating multiple image markers to generate a single integral image marker for configuring content such as game content. The present invention proposes a method of expressing, in a global coordinate system, feature points for each image marker whose positions are expressed in their local coordinate system by calculating relative positions of the image markers and applying the calculated relative positions to the image makers other than a reference image maker to transform 3D positions of feature points in each image marker.

Provided are an apparatus and method for analyzing a characteristic of a game player in real time. The apparatus includes at least one individual action determiner for calculating a player characteristic value indicating a level or tendency of a game player by giving a first weight to game play data values resulting from game play of the game player, an accuracy determiner for comparing the player characteristic value and a value set by an administrator, and calculating an accuracy value of the individual action determiner, a comprehensive level determiner for calculating a final characteristic value indicating a level or tendency of the game player by giving a second weight to the player characteristic values calculated by the individual action determiners when the accuracy value do not exceed a reference value, and a characteristic value output unit for outputting the final characteristic value.

A method for controlling a game character is provided. The method includes analyzing a game situation in which a character appears; and controlling a behavior of the character depending on a result of the analyzing. Accordingly, situation recognition and behavior control depending on the recognized situation are simultaneously performed using the same algorithm, so that the calculation amount can be reduced, and thus high artificial intelligence can be implemented with less computer resources. Also, a game developer does not need to implement individual behavior rules of characters depending on game situations since a situation of the game may be recognized through learning of an artificial neural network using a game database of game situations, and thus the behavior of characters can be controlled depending on the recognized situation.

Method for controlling game character

A database query system is provided. The database cache system includes: a network library which processes an access request issued by the online game server by using an input output completion port (IOCP); at least one database connection module which provides a connector for reading data from the database or recording data to the database; a database cache which stores data read from the database by the database connection module; and at least one cache buffer which is allotted to an IOCP worker thread corresponding to a database query request issued by the online game server and stores data read from the database, which is to be transmitted to the online game server.
