The Atari Asteroids Gymnasium environment provides the agent with a feature space that helps it navigate and interact with the game world. The key features include the agent’s position, forward direction, velocity, and angular velocity, which allow the agent to understand its motion and orientation within the asteroid field. The agent also receives information about the distance to the nearest asteroid, providing insight into its immediate surroundings. Additionally, the environment offers a set of ray-based features, such as the direction vectors of asteroids that the agent’s rays intersect. Although still under development, these ray-based features will help the agent detect and respond to asteroids more effectively, enhancing its decision-making abilities.
In addition to the feature space, the environment offers a pixel space where the agent receives a 64×64 pixel image of its surroundings. This image provides a visual representation of the environment, with each pixel corresponding to an element in the agent’s world. The feature space, combined with pixel data, allows for flexible learning approaches, enabling the agent to choose between raw visual input and more abstract representations of its environment. Together, these features create a rich, dynamic experience that facilitates the development of reinforcement learning agents capable of mastering the classic Asteroids game.
