camera movements

Implement smooth camera movements based on the position of the players near to you

added game computation label

Smooth movements added. Still need to change the zoom based on the farthest player in the scope, and to limit this scope.

mentioned in commit cad24986

Done server side, but needs to be done client-side using only the data sent but the server

Done client side by someone else but doesn't adapt (still need the network team's work)
