2D Navigation Gym Environment

This repository implements a Gym environment for simulating simple 2D navigation scenarios.

Installation

Activate a virtual environment or a conda environment. Then, run the following command:

pip install nav2d

Use cases

The building blocks in this toolbox are Point, Vector, and Polygon defined in nav2d.assets.elements.

• Point: p = Point(x, y), p.pos is a np.array. You can add a Vector to a Point to make it a new Point.
• Vector: inherits from Point. You can apply various algebraic operations to Vector. Many operators are overloaded there, e.g., sum(List[Vector]) gives you a singe Vector. Vector helps you manipulate multiple movements.
• Polygon: zone = Polygon(List[Point]). Given a zone and a point, zone.point_relative_pos(p) tells you their relative position IN | ON | OUT. A Polygon is defined by its vertices (Points).
