Abstract

Racing game is one of the genre that’s still popular today. Unity is one of many game engines one can use to develop a racing game. At Unity Asset Store, there is a free template called Micro-Game Karting which can only be played alone. In order to play player versus enemy mode, an artificial intelligence (AI) is needed for directing non-player character (NPC) who acts as the opponent. In racing game, the AI requires the use of movement algorithm and decision making system. For this study, the movement algorithm will use pathfinding. The algorithm is used as a guiding path when NPC is moving and avoiding obstacles in the way. Pathfinding will use waypoint system and raycasting to accomplish it. The decision making technique that will be used is decision tree. It functions as decision maker for NPC so it can determine the correct action to be done at certain time. Result of black box and white box testing showed NPC is functional. As for FPS (frame per second) test, performance suffers 0.2-0.3 FPS decrease for every addition of 2 NPCs. According to lap time test, the developed NPC is faster than ML NPC and driving test showed favorable outcome.

Abstract

AbstractRacing video game genre was still being popular today. One way to develop racing games quickly is by using a template or kit that is on the game engine. Racing Game Starter Kit (RGSK) was being the most popular racing game template for Unity game engine. However, there was problem in racing game’s NPC especially in RGSK related to NPC vehicle’s braking decision. The commonly used method is the Brake Zone, but the developers must manually place the zone themselves in the designated locations for braking. The solution that can be applied for that problem is see the angle formed by the vector of the NPC vehicle with the vector from 2 next following waypoint then determine the best configuration angle threshold for NPC braking, but this also has its shortcoming in which to get the best result, a proper threshold configuration is needed in each track. To resolve the problem, researcher proposed the method of machine learning, Naïve Bayes for the braking decision. Naïve Bayes uses two output classes (brake or no brake) in which the data will be obtained from the player. We use data from players who can control racing car games well or have never hit a wall and have fast lap times. The purpose of this study is to provide an alternative braking method to RGSK that can provide fast lap times but does not affect the game's FPS and without the need to determine or change any parameters on each track. The test result using RGSK v1.1.0a in Unity Game Engine showed that the proposed method can be an alternative method in RGSK braking decisions. Our NPC has faster lap time and was able to prevent the vehicle from crashing with the outer wall without dropping the game’s FPS (Frames per Second).Keywords: Braking Decision, Racing Game Starter Kit, Naïve Bayes, Machine learning, Unity engine AbstrakGenre video gim balap masih populer saat ini. Salah satu cara untuk mengembangkan game balap dengan cepat adalah menggunakan template atau kit yang ada di game engine. Racing Game Starter Kit (RGSK) adalah templat game balap paling populer pada Unity Game Engine. Namun, terdapat permasalahan NPC pada gim balapan terutama di RGSK terkait dengan keputusan pengereman kendaraan NPC. Metode yang digunakan untuk eksperimen jenis ini adalah Zona Rem. Namun, pengembang harus secara manual menempatkan zona tersebut di lokasi tertentu pada setiap lintasan. Solusi dari masalah ini yang sudah diterapkan pada RGSK v1.1.0a yaitu dapat menggunakan sudut yang dibentuk oleh vektor kendaraan NPC dengan vektor dari 2 titik arah berikutnya, kemudian menentukan ambang sudut terbaik untuk pengereman NPC, tetapi ini juga memiliki masalah yaitu untuk mendapatkan hasil putaran terbaik atau cepat, perlu menentukan konfigurasi ambang batas yang tepat di setiap trek. Untuk mengatasi masalah tersebut, peneliti mengusulkan metode pembelajaran mesin, Naïve Bayes untuk keputusan pengereman. Naïve Bayes menggunakan dua kelas output (rem atau tidak ada mengerem) di mana data akan diperoleh dari pemain. Kami menggunakan data dari pemain yang dapat mengontrol permainan mobil balap dengan baik atau tidak pernah menabrak tembok dan memiliki waktu putaran yang cepat. Tujuan dari penelitian ini adalah untuk memberikan metode pengereman alternatif untuk RGSK yang dapat memberikan waktu putaran yang cepat namun tidak mempengaruhi FPS game dan tanpa perlu menentukan atau mengubah parameter apa pun di setiap trek. Hasil pengujian menggunakan RGSK v1.1.0a di Unity Game Engine menunjukkan bahwa metode yang diusulkan dapat menjadi metode alternatif dalam keputusan pengereman RGSK. NPC kami mempunyai waktu putaran yang lebih cepat dan mampu mencegah kendaraan agar tidak menabrak dinding luar tanpa menjatuhkan FPS game (Frame per Detik).Kata kunci: Keputusan Pengereman, Racing Game Starter Kit, Naïve Bayes, Pembelajaran Mesin, Unity Engine

Abstract

AbstrakPerkembangan teknologi di bidang gim sekarang sudah sangat pesat terutama pada gim balapan. Gim balapan memiliki tujuan untuk memberikan pemain sebuah pengalaman yang menantang dan menyenangkan dalam sebuah balapan melawan mobil yang dikendalikan oleh gim tersebut atau biasa disebut dengan Non-Player Character (NPC). Pengembangan gim balapan tentunya tidak dapat lepas dari pengembangan NPC sebagai lawan main dari pemain. Pada umumnya NPC dikembangkan menggunakan metode waypoint untuk navigasi dalam melintasi trek balapan. Kekurangan dalam metode waypoint adalah harus diatur secara manual untuk setiap trek dan memakan waktu yang lama untuk mengatur waypoint pada setiap trek. Begitu juga untuk membuat NPC balap yang kompetitif dibutuhkan desain rule base yang kompleks. Peneliti mengusulkan menggunakan metode machine learning untuk mengatasi permasalahan tersebut. Unity3D menyediakan sebuah open-source API bernama Unity ML-Agents yang dapat digunakan untuk melatih NPC. NPC dilatih menggunakan metode reinforcement learning dengan Unity ML-Agents yang bertujuan untuk melatih NPC dengan cara memberikan reward agar mencapai hasil yang optimal. Hasil yang didapatkan dengan memanfaatkan Unity ML-Agents adalah NPC yang dapat melintasi berbagai macam trek dan dapat menghindari tabrakan. NPC yang telah dikembangkan dengan Unity ML-Agents juga mendapatkan waktu total yang lebih sedikit dibandingkan dengan waktu total yang diperlukan pemain untuk menempuh 3 lap putaran pada suatu trek yaitu 55,9 detik dibandingkan dengan 59,4 detik.Kata kunci: gim balapan, non-player character, unity ml-agents, reinforcement learning.Abstract[Non-Player Character (NPC) Development Using Unity ML-Agents in Karting Microgame] Nowadays, the development of game technology is very fast, especially in racing games. The racing game aims to provide players with a challenging and fun experience in a race against cars controlled by the game or commonly known as the Non-Player Character (NPC). Of course, the development of a racing game cannot be separated from the development of NPCs as opponents of the players. In general, NPCs were developed using the waypoint method for navigation across racetrack. The disadvantage of the waypoint method is that it must be set manually for each track, and it takes a long time to set the waypoint for each track. Likewise, making a competitive racing NPC requires a complex rule base design. Researchers suggest using machine learning methods to overcome these problems. Unity3D provides an open-source API called Unity ML-Agents which can be used to train NPCs. NPCs are trained using the reinforcement learning method with Unity ML-Agents which aims to train NPCs by providing rewards to achieve optimal results. The results obtained by utilizing Unity ML-Agents are NPCs that can traverse various kinds of tracks and can avoid collisions. NPCs that have been developed with Unity ML-Agents also get less total time compared to the total time required for a player to take 3 laps on a track, which is 55.9 seconds compared to 59.4 seconds.Keywords: racing game, non-player character, unity ml-agents, reinforcement learning.

Kata kunci: binatu, sistem informasi, android, waterfall, proses bisnis, UEQ   Abstract [The Development of Android-Based Shoes Washing Application on Sepatu Bersih] Sepatu Bersih is a shoe care service provider with one free pickup/delivery service for shoe washing in Malang City by ordering via WhatsApp. This service has several problems, such as implementing business processes taking a long time because you have to reply to customer messages, noting orders are done manually, and order records being prone to being lost. The customer's user experience is also not optimal because they must fill out the order form via WhatsApp and wait for the shopkeeper's reply. Based on these problems, using the waterfall development model, an Android-based information system was developed with the Firebase database for shoe-washing pick-up services. In addition, the current service business processes that use WhatsApp will be modeled as proposed business processes that use the app. Tests on this system are time simulations of current and proposed business processes, validation testing of system functional requirements, and user experience testing using the User Experience Questionnaire (UEQ) with statistical tests to determine the significance of the current service difference in the proposed service process. This study concludes that the proposed business process has a shorter average and total time, the validation test successfully fulfills all functional requirements of the system, and the user experience value of the UEQ aspect of Sepatu Bersih service has a significant difference towards a better user experience after using the system.
