UnityAI-FSM-SimpleAgentBehavior

An easy-to-integrate Unity FSM for basic agent AI behaviors, utilizing ScriptableObject for customizable and reusable AI states like Idle, Attack, Chase, Run, Die, Revive, Patrol, Wander, and Follow. This AI system also includes a Health Manager for managing the agent's health.

This repository contains the implementation of a simple finite state machine (FSM) for an agent AI in Unity. The FSM uses Unity's ScriptableObject to manage the states and behaviors of the agent, allowing for easy customization and reusability in different game scenarios.

Description

The agent AI's behavior is governed by a comprehensive FSM with various states:

  • Idle (0): The default state where the agent is not engaged in any activity.
  • Attack (1): Activated when the agent is close enough to the player. The agent performs an attack action.
  • Chase (2): Triggered when the player is detected within a certain range. The agent moves towards the player.
  • Run (3): A state where the agent flees from a threat or danger.
  • Die (4): The state when the agent's health reaches zero, resulting in death.
  • Revive (5): If the agent can be revived, this state handles the revival process.
  • Patrol (6): The agent follows a predefined patrol route or path.
  • Wander (7): A state where the agent roams around randomly.

Transitions between these states are based on various game conditions, including player proximity and the agent's health.

Implementation

The FSM is implemented using Unity's ScriptableObject, allowing for an efficient and modular approach. Additionally, a Health Manager is integrated into the system to manage the agent's health. The state transitions and behaviors are handled within Unity, making it easy to integrate and modify for any Unity-based game project.

Prerequisites

  • Unity Engine (preferably the latest version)
  • Basic understanding of Unity's interface and ScriptableObject

Getting Started

To use this FSM in your Unity project, follow these steps:

  1. Clone the repository:
  2. Open your Unity project and import the cloned FSM assets.
  3. Drag and drop the FSM ScriptableObject into your game objects to integrate the AI behavior.
  4. Customize the FSM, its states, and the Health Manager as per your game's requirements.
