Input/Output: Keyboard Input

Objective

Students must implement keyboard event listeners to handle player input and control game entities.

Evidence

Keyboard input handling in game components:

• GameLevelOutside.js - W, A, S, D key handling
• GameLevelMaze.js - Arrow key and WASD controls
• Multiple levels - Event listeners for player movement

Implementation Details

• Event listeners for keydown/keyup events
• Key code detection for specific keys
• State management for simultaneous key presses
• Integration with player movement system
• Debouncing repeated key events

Key Concepts

• addEventListener for keyboard events
• Event object properties (key, keyCode, which)
• Key detection and handling
• Simultaneous key presses
• Key event propagation and bubbling
