As an AI text-based model, I can provide you with a simple JavaScript game code that simulates a car racing game similar to GTA 6. However, please note that this is a basic implementation; creating a fully-featured game like GTA 6 would require extensive development time and resources. Here's an example of a simple car racing game:
To use this code, you need to provide a car image URL by replacing `emozi_all/car.png` in the `carImage.src` line. Additionally, you can enhance the game further by adding obstacles, collisions, scoring, levels, and more.
Note: This is a basic car movement simulation and not a complete GTA 6 game. It is provided as a starting point for your game development.
