Sure! Here's an example of a simple game featuring Mario and Sonic using pictograms and smartphone controls. It is implemented as a single HTML file containing JavaScript enclosed in script tags.
In the provided example, the game board is represented by a div element with id "gameBoard." The characters (Mario and Sonic) are represented by two additional div elements with ids "mario" and "sonic" respectively. Pictogram images for Mario and Sonic should be placed in the same directory as the HTML file with the names "emozi_all/game.png" and "emozi_chicken.png" respectively.
To control the characters, the player can use the left and right arrow keys to move Mario and the 'A' and 'D' keys to move Sonic. The characters are restricted to move within the dimensions of the game board, which is set to 400px width and 300px height.
When the webpage is loaded, an event listener is added to handle key presses. The characters' movements are controlled by the handleKeyPressed function, which updates their positions on the game board accordingly.
Note: This is a basic example and can be enhanced with additional features and functionalities as per game requirements.
