Server Simulates Logic of players

[3bhady]

In Server.js, for each room:

• function Simulate() should iterate over the players.
• Each player is moved by delta time and it's speed of moving from start of a block till the end of it.
• If the new position will cause the player to jump cells then it should first iterate on each cell it would jump.
• If the player was registered to move and the player reached the end of the cell:
  1. The player changes directions.
  2. Each user in the room receives either the grid or run length of the grid.
