# iso-bot — Isometric Game Bot Engine

A modular, high-performance bot framework for isometric games. Screen-reading only — no memory injection, no hooking, no client modification.

First game: **Diablo II: Resurrected**

## Design Principles

- **Plugin-based**: Engine is game-agnostic. All game logic in plugins implementing `plugin.Plugin`
- **Screen reading only**: Captures screenshots, analyzes pixels/templates, sends inputs
- **Human-like**: Bézier mouse movement, randomized delays, fatigue, scheduled breaks
- **VM-safe**: Engine runs on host, captures VM window — game never sees the bot
- **Declarative loot**: YAML rule engine for item filtering
- **API-first**: REST + WebSocket for remote dashboard control

## Adding a New Game

Implement these interfaces from `pkg/plugin`:
- `GameDetector` — detect game state from screenshots
- `ScreenReader` — extract items, enemies, text from screen
- `Routine` — automated farming sequences
- `LootFilter` — item pickup rules

## Usage

```bash
# Build
go build -o iso-bot ./cmd/iso-bot

# Run
./iso-bot --game d2r --routine mephisto --api :8080
```
