Sure, I can help you create a simple game based on your instructions. Here's an example of a game where you need to operate a Budapest train:
Explanation:
- This example uses a simple HTML canvas element to draw the game.
- The train starts at position 0 on the x-axis and moves to the right with a constant speed (`trainSpeed`).
- The `gameLoop` function is responsible for updating the train position, clearing the canvas, drawing the train, and checking if the train reached the destination or returned to Budapest.
- When the game is over (train reaches Simontornya or returns to Budapest), an alert message is displayed.
Keep in mind that this is a basic implementation to give you an idea of how to create a game using JavaScript within a single HTML file. You can enhance it by adding user input, additional features, and graphics as per your needs.
