Most of the match-3 puzzle games supports automatic play using the MCTS algorithm. However, implementing reinforcement learning agents is not an easy job because it requires both the knowledge of machine learning and the way of complex interactions within the development environment. This study proposes a method in which we can easily design reinforcement learning agents and implement game play agents by applying PPO(Proximal Policy Optimization) algorithms. And we could identify the performance was increased about 44% than the conventional method. The tools we used are the Unity 3D game engine and Unity ML SDK. The experimental result shows that agents became to learn game rules and make better strategic decisions as experiments go on. On average, the puzzle gameplay agents implemented in this study played puzzle games better than normal people. It is expected that the designed agent could be used to speed up the game level design process.

There are many essential elements in making the realistic 3D games, of which one of the most important is mapping. Mapping can add the details to 3D objects easily, which are impossible or difficult by modeling alone, and can reduce file data capacities to run the game engine. The theory of the mapping is to throw 2D image on 3D object correctly, but they do not match each other at the rate of 1:1 100 percent completely due to the difference of the fundamental property of them. To solve this problem, various kinds of mapping methods are developed and used. This paper will compare and analyze the characteristics, and merits and demerits of these various kinds of mapping methods and will inquire which method is the most efficient one.

This paper focuses on developing a first-person 3D game to provide extreme fear to players through realistic camera direction utilizing the features of action cameras. As a new camera production technique, we introduce perspective distortion using a wide-angle lens and camera shake when moving to provide higher immersion than existing games. The theme of the game is horror room escape, and the player starts with a firearm, but in order to overcome the concern that the game's difficulty is low due to the use of firearms, the player is asked to control the use of firearms by imposing burdens such as chasing monsters and reducing the number of magazines. The significance of this paper is that we developed a new type of 3D game that maximizes the fear effect of players through realistic production.

This study suggests a methodology for automatically extracting placing information from 2D reinforced concrete details drawings and generating a 3D reinforcement placing model to develop a mobile augmented reality for bar placing work. To make it easier for users to acquire placing information, it is suggested that users takes pictures of structural drawings using a camera built into a mobile device and extract placing information using vision recognition and the OCR(Optical Character Registration) tool. In addition, an augmented reality app is implemented using the game engine to allow users to automatically generate 3D reinforcement placing model and review the 3D models by superimposing them with real images. Details are described for application to the proposed methodology using the previously developed programming tools, and the results of implementing reinforcement augmented reality models for typical members at construction sites are reviewed. It is expected that the methodology presented as a result of application can be used for learning bar placing work or construction review.

It is impossible to do real verification on design spaces before their completions due to the characteristics of building and interior space designs. So, in designing spaces, designers should reflect their real experiences in their lives into their design works. 3D games where GPU and other kinds of advanced technologies have bee applied first show their leads in technologies have bee applied first show their leads in technologies about 5 years than VRML. Those games which are produced reflecting real environment as it is could be regarded as the most excellent tool in their completeness level of physical environment due to their characteristics. This means that if 3D game engines employing GPU are used effectively they could be used as a presentation tool for virtual spaces. This study studies the expressions of virtual constructions through 3D game engines employing GPU, not in VRML-based virtual spaces on Webs but in immersion-type virtual spaces.

In the recent gaming industry, the paradigm has been changed with upcoming core-platform as time goes by. Arcade, console, PC online and smart device platforms are representative ones. In recently, the platform is changed to multi-platform which connecting to smart device and other platforms. Besides, the multi-platform without PC is up-coming. This paper suggests that a kind of multi-platform which connecting from smart devices to arcade devices be aware of lack of continuous. It provides a new arcade gaming condition connecting to smart devices, then supplies online network conditions to the arcade gaming machine. The original arcade game was lack of continuous and the game platform was so simple, but now, it could be focused from players by connecting to smart devices to increase the gaming machines' continuity. Furthermore, Bluetooth communication module and wireless Wi-Fi communication module are used to adapt various communication environments. The Unity3D engine would make contents' expandability.

VR기기를 착용하고 주변 시야가 차단된 상태로 일정 시간 사용하면, 다소 편차는 있지만 누구에게나 사이버 멀미 현상이 쉽게 일어날 수 있다는 문제점이 VR 관련 콘텐츠 개발자 및 사용자들에게 대두되고 있다. 이 문제를 현시점에서는 완전히 해결할 수는 없지만, 일반적으로 VR 게임을 개발할 때 사전에 숙지해야 할 중요한 부분 중 하나이다. 따라서 사용자가 VR 게임을 체험하기 전에 사이버 멀미를 예방하기 위해, 미리 개발 과정에서부터 사이버 멀미가 일어날 수 있는 변수를 최대한 줄이며 개발하는 여러 가지 방안에 대해 연구하였다. 본 논문에서는 먼저 고려해야 할 사항으로 사이버 멀미 현상이 일어나는 원인을 분석하고, 이를 예방할 수 있는 방법을 모색하여 상용 엔진인 Unity3D를 이용한 VR 게임 개발에 실제로 적용하였다.

In this paper, we Introduce the Unreal Tournament (UT) game and the Gamebots system. The former it a well-known 3D first-person action game and the latter is an intelligent agent research testbed based on UT And then we explain the design and implementation of KGBot, which is an intelligent non-player character deploying effectively within the 3D virtual environment provided by UT and the Gamebots system. KGBot is a bot client within the Gamebots System. KGBot accomplishes its own task to find out and dominate several domination points pro-located on the complex surface map of 3D virtual environment KGBot adopts UM-PRS as its control engine, which is a general BDI agent architecture. KGBot contains a hierarchical knowledge base representing its complex behaviors in multiple layers. In this paper, we explain details of KGBot's Intelligent behaviors, tuck af locating the hidden domination points by exploring the unknown world effectively. constructing a path map by collecting the waypoints and paths distributed over the world, and finding an optimal path to certain destination based on this path graph. Finally we analyze the performance of KGBot exploring strategy and control engine through some experiments on different 3D maps.
