As the industry develops, the technology used for games is also being advanced. In particular, AI technology is used to game automation and intelligence. These game player patterns are widely used in online games such as player matchmaking, generation of friendly or hostile NPCs, and balancing of game worlds. This study proposes a model generation method for game players. For model generation, attributes such as hunting, collection, movement, combat, crisis management, production, and interaction were defined, and patterns were extracted and modeled using decision tree method. To evaluate the proposed method, we used the game log of a commercial game and confirmed the meaningful results.

In this paper, we design and implement a mobile game based on windows phone platform. Visual Studio and the Windows Mobile software development kit(SDK) and developer tool kits (DTK) make it possible to create software for the Windows Mobile platform in Visual C#. Also The XNA Framework is the set of .NET libraries that developers will code against to build games. XNA Framework support PC and XBOX and a ZUNE HD multiplex platform environment and 2D and 3D games provides the necessary functions to a development. XNA Framework is to make it easier to develop games because the codes which are succeeded creates with automatic, implements a game development relation resource and the game logic. The key idea of our game is that we use shooting and ranking system to raise fun.

By the recent success of the iPhone and the App Store, software developers from all over the world challenge to list their applications on the App Store and sell them worldwide. And major mobile companies in Korea are following the Apple by opening open markets to distribute software products running on their mobile devices. In this paper, we describe the development of an action game for iPod 'Hexa-Samkukgi'. The game is developed using Cocos2d engine.

본 논문에서는 오목을 두는 지능적 프로그램을 설계하고 구현하였다. 규칙은 렌주 룰(renju rule)을 기준으로 하였으며, $15{\times}15$ 게임 판에서 오목을 둔다. 초기에는 문제 분석을 통하여 분석된 가중치로 판단을 하여 판단을 하여 게임을 진행하도록 하였으나, 반복된 수행의 경험적 판단을 통하여 얻은 정보로 여러 차례 수정하며 고정된 가중치를 구성하고, 이 가중치를 게임에서 돌을 놓을 때 평가 기준으로 삼도록 하였으며, 최소-최대 게임 트리(min-max game tree)를 이용하여 상대가 있는 게임을 수행할 수 있도록 하였다. 또한 프로그램 자신에게 유리한 수를 찾기 위한 탐색에서 무의미한 노드들의 전개를 줄여 제한된 시간안에 좋은 수를 찾을 수 있도록 알파 베타 가지치기(alpha-beta pruning)를 사용하도록 프로그램을 구현하였다. 이렇게 구현된 오목 프로그램은 게임을 본 프로그램과 게임 하기 원하는 주변의 일반인들에게 90% 이상의 승률을 보이고 있었다.

본 논문은 영속적 RPG게임에서 사용자에게 제공되는 퀘스트 유형의 절차적 생성 기법에 대한 연구이다. 영속적 월드(persistent world) 환경은, 게임 사용자를 포함한 다양한 게임 구성 자원간의 상호작용을 통해 서사를 생성하는 가상 월드의 특징을 가지고 있다. 본 실험은 서사의 핵심 자원인 NPC(Non-Player Character) 및 다양한 월드 자원들을 가진 가상의 영속적 월드 하에, NPC들이 창발적인 퀘스트를 지속적으로 생성하도록 하였다. 이를 통해 영속적 가상 월드의 NPC 자원들이 곳곳에서 창발적 퀘스트 유형을 지속적으로 생성하는 것을 확인 할 수 있었다.

Recently, online-game industry has been rapidly expanding in these days. But, the various game service victimized cases are generated by the bots program. Particularly, the abnormal collection of the game money and item loses the inherent fun of a game. It reaches ultimately the definite bad effect to the game life cycle. In this paper, we propose a Bots detection method by observing the playing patterns of game characters with game log data. It analyzed behaviors of human players as well as bots and identified features to build the model to differentiate bots from human players. In an experiment, by using the served online-game, the model of a user and bots were generated was distinguished. And the reasonable result was confirmed.

As the main means to cope with the stubborn problem of drunk driving, the inspection of drunk driving has already been paid more attention and thus reinforced. In this paper, we model this scenario as a Stackelberg game, where the police department (called defender) allocates resources dynamically in terms of the traffic situation on the traffic network to arrest drink drivers and drivers who drink (called attacker), whether choosing drunk driving or designated driving service, expect to minimize their cost for given travel routes. However, with the number of resources are limited, our goal is to calculate the optimal resource allocation strategy for the defender. Therefore, first, we provide an effective approach (named OISDD) to fulfill our goal, i.e., generate the optimal strategy to inspect drunk driving. Second, we apply OISDD to directed graphs (which are abstracted from Dalian traffic network) to analyze and test its correctness and rationality. The experimental results show that OISDD is feasible and efficient.

The purpose of this study was firstly, to evaluate the contents of vocabulary game applications for young children's language learning. and secondly, to examine whether there is any differences between Korean and English word games in terms of the evaluation score. For this purpose, the word game applications in smart phone and tablet PC were analyzed, which included 30 Korean word games and another 30 English ones. The criteria to evaluate the contents were developed based on Children's Software Evaluation Instrument developed by CTR, the multimedia evaluation standard by Hee Sook Park, Young Joo Lee, and mobile contents evaluation standard by Soo Ui Choi. As a result, the educational value got the highest score whereas the design characteristics area got the lowest score in the whole evaluation analysis. And English word game applications mostly got higher score than Korean versions. The result of this study would suggest the way to evaluate educational game applications in use and to contribute to developing educational game contents aimed at young children's language learning.

The windows games and the console games that use DirectX occupied 20% or more of world game market and that are developed by C++ Language occupied 75% or more of the market. This study proposed that commonality and variability for code of the 20 projects based on DirectX and C++ is analysed and patternized, that common modules are created, and that modules are modeled. As a result of applying a case study, it is verified that the proposed model reduces effort in game development.

Flash is the most popular 2D animation and game development software, supporting vector and media technology at the core, which enables the development of small and pithy games. It is widely used in Web animation, courseware, TV commercials, game development, and other works of design. In this paper, we propose a control movement function and auxiliary functions for an alpine skiing game based on ActionScript 3.0. The control movement function is designed with moving phases (i.e., free fall, sliding, projectile, and landing). The auxiliary functions include drawing path, start/restart movement, and saving the highest score. In addition, for the visual design of our game, we designed animations in connection with a character and background. In order to facilitate testing the friction, users can input a chosen friction value. Without user input, the friction default is set at 0.97.
