Summary

This PR introduces a new Doom environment for OpenEnv, wrapping the ViZDoom platform to provide visual reinforcement learning capabilities for Doom-based scenarios. The environment supports multiple scenarios, configurable resolutions, discrete/continuous action spaces, and includes comprehensive documentation with visual examples.

Overview

The Doom environment (doom_env) integrates ViZDoom - a Doom-based AI research platform - into the OpenEnv framework, enabling agents to:

• Learn from visual observations (RGB or grayscale screen buffers)
• Execute actions in 3D game environments
• Train on multiple built-in scenarios (basic, deadly_corridor, defend_the_center, etc.)
• Track game variables (health, ammo, kills)
• Deploy via Docker or run locally

What's Included

Core Implementation

• models.py - Data models for actions and observations

  • DoomAction: Action dataclass with support for discrete actions or button combinations
  • DoomObservation: Observation dataclass with screen buffer, game variables, rewards, metadata

• client.py - HTTP client for connecting to Doom servers

  • DoomEnv: Full-featured client with rendering support (OpenCV/matplotlib)
  • Automatic numpy type conversion for JSON serialization
  • Client-side rendering with render() method

• server/doom_env_environment.py - Core ViZDoom wrapper

  • Configurable scenarios, resolutions, screen formats
  • Discrete actions and button combinations support
  • Episode management and state tracking

• server/app.py - FastAPI server application

  • Environment variable configuration (scenario, resolution, format)
  • Web interface integration
  • Health check endpoint

Docker Support

• server/Dockerfile - Standalone Docker image
  • Based on python:3.11-slim
  • Includes all ViZDoom system dependencies
  • Configurable via environment variables
  • Works for both local builds and HuggingFace deployment
  • Build command: docker build -t doom-env:latest -f src/envs/doom_env/server/Dockerfile src/envs/doom_env

Documentation

  • Deployment instructions
  • Visual examples with ASCII art Doom Slayer

• GIF_GENERATION.md - Guide for generating scenario GIFs

  • Step-by-step instructions
  • Example commands
  • Troubleshooting tips

• Defend the Center - Survival mode defending against monsters
• Defend the Line - Protect a line from advancing enemies
• Health Gathering - Navigate maze collecting health packs
• My Way Home - Navigation to goal location
• Predict Position - Predict enemy positions
• Take Cover - Strategic cover-based combat

2. Flexible Configuration

Environment Variables:

DOOM_SCENARIO=basic                 # Scenario selection
DOOM_SCREEN_RESOLUTION=RES_640X480  # Resolution (160x120 to 1024x768)
DOOM_SCREEN_FORMAT=RGB24            # RGB24 or GRAY8
DOOM_WINDOW_VISIBLE=false           # Show game window
ENABLE_WEB_INTERFACE=true           # Enable /web UI

3. Action Spaces

• Discrete Actions: Simple integer action IDs (0-3 for basic scenario)
• Button Combinations: Full control with custom button lists

4. Rendering Options

• Web Interface - Browser-based UI at /web endpoint
• Client-side Rendering - OpenCV or matplotlib visualization
• RGB Array Mode - Return numpy arrays for custom processing

5. Docker Deployment

Local Build:

docker build -t doom-env:latest -f src/envs/doom_env/server/Dockerfile src/envs/doom_env
docker run -p 8000:8000 -e DOOM_SCREEN_RESOLUTION=RES_640X480 doom-env:latest

HuggingFace Deployment:

cd src/envs/doom_env
openenv push

Technical Details

Architecture

• Client-Server Model: HTTP-based communication via OpenEnv framework
• ViZDoom Integration: Native Python bindings to Doom engine
• Screen Buffer Format: Flattened RGB/grayscale arrays for efficient transmission
• State Management: Episode tracking, step counting, game variables

Fixed Issues

1. Docker Build for HuggingFace

   • Fixed build context to work with both local and HF deployments
   • Changed from copying src/core/ to installing openenv-core via pip
   • Updated paths: WORKDIR /app/env, COPY . ., pip install -e .

2. Environment Variable Configuration

   • server/app.py now reads DOOM_* environment variables
   • Docker resolution changes take effect at runtime
   • Proper defaults for all configuration options

3. JSON Serialization

   • Added numpy type conversion in client.py::_step_payload()
   • Handles np.int64, np.float32, numpy arrays
   • Filters out None values from payload

4. Rendering Window Size

   • doom_visualizer.py auto-scales windows based on resolution
   • Uses cv2.resize() with INTER_NEAREST for pixel art preservation
   • Target window size: 1024px width with appropriate scaling

5. OpenEnv Validation

   • Restructured server/app.py to follow snake_env pattern
   • Added main() function with proper if __name__ == "__main__" block
   • Passes openenv validate for multi-mode deployment

Usage Examples

Basic Usage

from doom_env import DoomEnv, DoomAction

# Connect to server
client = DoomEnv(base_url="http://localhost:8000")

# Reset environment
result = client.reset()
print(f"Initial health: {result.observation.game_variables[0]}")

# Take actions
for _ in range(100):
    action = DoomAction(action_id=1)  # Move left
    result = client.step(action)

    if result.observation.done:
        print(f"Episode finished! Total reward: {result.reward}")
        break

client.close()

Docker Mode

from doom_env import DoomEnv, DoomAction

# Start container automatically
client = DoomEnv.from_docker_image("doom-env:latest")

result = client.reset()
result = client.step(DoomAction(action_id=0))

client.close()

With Rendering

client = DoomEnv.from_docker_image("doom-env:latest")
result = client.reset()

for _ in range(100):
    result = client.step(DoomAction(action_id=1))
    client.render()  # Display the game
