ARACHNID RL Dataset

This dataset contains reinforcement learning transitions collected from human gameplay of ARACHNID RL, a 2D Atari-inspired space shooter. It contains about 2,831 samples of human gameplay data from a simple Atari-inspired space shooter game. Players control a spider-like ship to shoot asteroids and aliens while collecting diamonds. To build your own datasets download the ARACHNID RL file in the /gym/ folder of this repo. The game features desktop keyboard and mobile oneclick browser support. The dataset is designed for RL research, such as training agents via imitation learning or behavioral cloning from human demonstrations.

Dataset Structure

The main dataset is in data/train.jsonl in JSON Lines format. 1.83 MB, stored primarily as a JSON Lines file (train.jsonl), with an auto-converted Parquet version for efficient loading. Each entry represents a single transition, including timestamp, session/player ID, event type (e.g., shoot, move, gamestart, destroyalien), action taken (e.g., left, right, shoot), reward (e.g., +15 for collecting diamonds), done flag, current state (as JSON with position, velocity, score, lives, nearby objects, etc.), next state, and event details.

Data Format

Each line in data/train.jsonl is a JSON object with:

—state: Game state (JSON string containing position, velocity, lives, score, nearby objects)
—action: Player action (left, right, up, down, shoot, boost, none)
—reward: Immediate reward
—next_state: Next game state (JSON string)
—done: Episode termination flag
—event_type: Type of event
—event_details: Additional metadata (JSON string)
