Sure, I can help you with that! Here's an example of a simple multiplayer fighting game written in HTML and JavaScript, using pictograms for the weapons. Keep in mind that this is just a basic implementation to give you an idea, and you can modify and expand it according to your requirements:
This code sets up a simple multiplayer fighting game with two players, each with their own name, health, and weapon. The players can click on specific areas of the canvas to attack or heal each other. The game updates the state and checks for a winner after every action.
Please note that this is just a basic implementation and you can enhance it further with features like special attacks, different weapons, animations, etc.
