How do I use translate() to keep my player in the center of the screen while it is moving?

I am trying to make Among Us but its coded in JavaScript(originally in C++ in Unity) and I have run across a problem: My player can move off the screen! This is really frustrating, as I am trying to make a game that is bigger than the window height and width. There is no way I can add a minimal reproducible example, as my code relies on itself to work. But the code is here: https://editor.p5js.org/LttntLark/sketches/03MGbFiUhG ...

What I have tried:

I have tried moving the map, and not the player, then I realized I wanted this to be a multiplayer game. If you can, please help, as all of it is appreciated. If there is something missing, I am open to share more information.

You need to check the player's position against the dimensions of the screen before you move it.

You don't move the map, you move the "view port".

You shift the port (up, down, left, right) as the player steps up, down, left, right.

In multiplayer, each user controls their own "view port" (x,y and width and height).

And the "view port" usually moves only when the user moves it if the "action" can occur in multiple places at the same time ... versus a "single shooter " game; there the port does follow the player.
