As an AI text-based model, I can help you with the code structure and provide some guidance on creating a simple 3D first-person shooter (FPS) game using JavaScript within a single HTML file, but I won't be able to provide a complete implementation of a game as complex as Valorant. Nevertheless, here's a simplified example of how you can get started:
Explanation:
- The HTML file contains a `<canvas>` element where the game graphics will be rendered.
- The JavaScript code initializes the game canvas, sets up player variables, and implements game functions.
- The game logic is managed by the `gameLoop` function, which runs continuously.
- User input is handled by the `handleInput` function, which adjusts the player's position based on touch/mouse events.
- The `update` function handles the game logic, and the `draw` function renders the game objects onto the canvas.
- The `startGame` function initializes the game by adding event listeners for touch and mouse input, then starts the game loop.
Please note that this is just a basic structure to get you started with a simple 2D game. Creating a full-fledged 3D FPS game like Valorant for mobile would require a significantly more complex codebase, including 3D rendering, game physics, collision detection, and multiplayer functionality.
