Introduction

The development of artificial intelligence (AI) in the game industry is crucial to increase player involvement and pleasure. This study aims to implement the A* and Finite State Machine (FSM) algorithm to the Boss character in the top-down shooter game "From The Downtown" to increase the challenges and involvement of players. The A* algorithm is used for track search, allowing the boss to find optimal routes when chasing players. Meanwhile, FSM is used to manage the boss's behavior based on various circumstances in the game, such as attacking, chasing, and silent.

Background of the Study

The game industry has seen significant advancements in AI development in recent years. AI has become an essential component in creating engaging and immersive gaming experiences. The development of AI in games has led to the creation of more realistic and responsive characters, which in turn has increased player involvement and satisfaction. However, the development of AI in games is a complex task that requires a deep understanding of game mechanics, player behavior, and AI algorithms.

Literature Review

The A* algorithm is a popular pathfinding algorithm used in games to find the shortest path between two points. It is widely used in games to create more realistic and responsive characters. The FSM is a behavioral algorithm used to manage character behavior based on various circumstances in the game. It is used to create more dynamic and responsive characters that can adapt to changing situations in the game.

Methodology

The research process involves the development and integration of the two algorithms into the game machine. Testing is carried out to evaluate the performance and responsiveness of the boss. The results show that the A* algorithm functions well, allowing the boss to find an effective path to the player. With the use of FSM, the boss's behavior becomes dynamic and responsive in accordance with changes in the situation in the game.

Implementation of the A Algorithm*

The A* algorithm is implemented in the game to find the shortest path between the boss and the player. The algorithm uses a heuristic function to estimate the distance between the boss and the player. The heuristic function is used to guide the search towards the player, allowing the boss to find the shortest path.

Implementation of the Finite State Machine

The FSM is implemented in the game to manage the boss's behavior based on various circumstances in the game. The FSM is used to create more dynamic and responsive characters that can adapt to changing situations in the game. The FSM is implemented using a state machine architecture, which consists of a set of states and transitions between states.

Testing and Evaluation

Testing is carried out with various scenarios to ensure the reliability and effectiveness of the AI applied. This trial aims to see how the boss responds to various situations, such as when players hide, attack, or use other strategies to fight the boss. The test results show that the combination of algorithms A* and FSM not only increases the level of challenges, but also enriches the play experience by providing a more natural and responsive interaction.

Contribution to AI Development in the Game

The application of these two algorithms made a significant contribution in the development of AI in the game, especially in creating a smarter and more challenging boss. The implementation results show that the combination of algorithms A* and FSM can be applied to other games to improve the reality and excitement of the game. In this way, this research provides new insights in the development of AI for the boss character in the game, which can be useful for the overall game industry.

Conclusion

Through this study, it can be concluded that the application of the A* and FSM algorithm to the boss characters in the game "From The Downtown" has succeeded in increasing challenges and increasing player interactions. With the increasing level of player involvement, it is hoped that the play experience will be more satisfying. Innovations in the development of AI not only benefit the game that is being developed, but also opens the way for further application in the broader game industry.

Future Work

Future work can be done to improve the AI in the game by incorporating more advanced algorithms and techniques. This can include the use of machine learning algorithms to create more realistic and responsive characters. Additionally, the use of more advanced state machine architectures can be explored to create more dynamic and responsive characters.

Limitations of the Study

The study has some limitations that need to be addressed. The study only focuses on the implementation of the A* and FSM algorithm in the game, and does not explore other AI algorithms and techniques. Additionally, the study only tests the AI in a limited number of scenarios, and does not explore the AI in more complex and dynamic situations.

Recommendations for Future Research

Future research can be done to explore the use of more advanced AI algorithms and techniques in the game. This can include the use of machine learning algorithms to create more realistic and responsive characters. Additionally, the use of more advanced state machine architectures can be explored to create more dynamic and responsive characters.
