So I'm making my first ever online-mulitplayer game on scratch, and I've figured out how to connect players, but I have a few problems that I don't know how to solve:
1. When a player changes direction, the other player/s don't see them switch around, so they just kepp facing one to everyone else, but on that player's screen, they ARE moving.

2. In this game, there's a punching mechanic, where the player plays a little punch animating for about 5 frames. It's the same problem as the first one, where none of the other players are seeing one another go through that animation.

3. I don't know how to get the game to show each player's individual usernames. (Example: above a player's head, it shows their unique scratch username. I also want all the other players to be able to see this)

Thank you so much if you can help me out with these issues!!

You don't say what info you're passing via the cloud or how you're handling that. You probably need to pass the current direction or at least a basic 0/1 for left/right if that's enough. The username also needs to be encoded and passed and then it's a case of using a text engine to write the name to screen.
