get me a script that allows me to write a command in the chat that lets me control another player

Creating a script to control another player in a multiplayer environment raises significant ethical and legal concerns, as it involves taking control of another player's actions without their consent. This is generally considered cheating and can lead to bans or other penalties in most gaming communities. If you're developing a game and looking to implement player interactions or specific commands for controlling NPCs or other game elements, I can help you with that. Please provide more details about the game engine or platform you're using (like Unity, Unreal Engine, etc.), and I can guide you in a way that's ethical and adheres to game development standards.
