Introduction
In the 1990s, Craig Reynolds developed algorithms for common AI behaviors. They allowed AI agents to seek out or flee from a target, follow a pre-defined path, or face in a particular direction. They were simple, repeatable tasks that could be broken down into programming algorithms, which made them easy to reuse, maintain, combine, and extend.
While an AI agent's next action is based on decision making and planning algorithms, steering behaviors dictate how it will move from one frame to the next. They use available information and calculate where to move at that moment.
Joining these systems together can give sophisticated and graceful movement while also being more efficient than complex pathfinding algorithms like A*.
The framework
This project is a framework for the Godot game engine. It takes inspiration from the excellent GDX-AI framework for the LibGDX java-based framework.
Every class in the framework extends Godot's Reference type. There is no need to have a complex scene tree; you can contain that has to do with the AI's movement inside GDScript classes.
How it works
In GSAI, a steering agent represents a character or a vehicle. The agent stores its position, orientation, maximum speeds, and current velocity. The agent stores a steering behavior that calculates a linear or angular change in velocity based on its information.
The coder then applies that acceleration in whatever ways is appropriate to the character to change its velocities, like RigidBody's apply_impulse, or a KinematicBody's move_and_slide.
