|
## Getting Started
|
|
|
|
1. **Open the game**: Simply open `index.html` in a modern web browser
|
|
2. **Start playing**: The game will automatically initialize and start
|
|
3. **Use controls**:
|
|
- **Space**: Pause/Resume
|
|
- **D**: Toggle debug mode
|
|
- **R**: Reset game
|
|
- **Mouse wheel**: Zoom in/out
|
|
- **F11**: Toggle fullscreen
|
|
|
|
## Controls Reference
|
|
|
|
### Keyboard Controls
|
|
- `SPACE` - Pause/Resume game
|
|
- `D` - Toggle debug information display
|
|
- `R` - Reset game to initial state
|
|
- `F11` - Toggle fullscreen mode
|
|
|
|
### Mouse Controls
|
|
- `Mouse Wheel` - Zoom camera in/out
|
|
- `Click buttons` - Use UI controls for game management
|
|
|
|
### UI Controls
|
|
- **Play/Pause** - Start/stop game simulation
|
|
- **Speed Control** - Adjust game speed (0.5x, 1x, 2x, 4x)
|
|
- **Reset Game** - Return to initial game state
|
|
|
|
## Game Mechanics
|
|
|
|
### Player AI
|
|
Each player has sophisticated AI that includes:
|
|
- **Role-based behavior** (forwards vs defensemen vs goalie)
|
|
- **Formation positioning** based on game situation
|
|
- **Puck awareness** and decision making
|
|
- **Teammate cooperation** for passing and positioning
|
|
- **Opponent pressure** and defensive reactions
|
|
|
|
### Physics System
|
|
- **Realistic puck physics** with momentum and friction
|
|
- **Player collision detection** and response
|
|
- **Board bouncing** with energy conservation
|
|
- **Goalie save mechanics** based on skill attributes
|
|
|
|
### Hockey Rules
|
|
- **Offside detection** when players cross lines ahead of puck
|
|
- **Icing calls** for long shots across multiple zones
|
|
- **Penalty system** for infractions like checking and interference
|
|
- **Power play situations** with player advantages
|
|
- **Faceoff mechanics** at center ice and zone dots
|
|
|
|
