It’s 2D games Plaftormer such Fire and Water Old Flash game
I created a room and a connection to it and after that a level, but when creating characters, their control breaks down
if the character control is performed using the buttons, but the camera and the control itself is shown on the screen of another player and his is mine and how and what to do with it
Please help me with this code
