Space Game needs two players per game. The first player should create a new game, and the second player should use their friend's room code to join the same game.
The aim is to collect the gems before the other player. When a gem is collected, another one will appear.
The game uses a 'ping-pong' system to send frequent updates between the server and client. The client's responses are delayed by a random time value between 0 and 6.5 seconds to simulate realistic network conditions, which vary over time.
Player movement is sped up or delayed depending on the game's latency, so that all clients appear to have the same frame rate and the game is fair.
As the game map is very small, interest management is implemented in terms of 'rooms' and also a redundant Area of Interest.
Only the players, scores and gems belonging to the same room as the client should be displayed on the client's screen.
Other players/enemies are only displayed if the AOI of the enemy is the same as the current client. (Redundant and always true)
Other players' movement is displayed according to the direction and speed of travel, rather than live positions, in order to compensate for network problems and delays.
Tween animations are used to display other players' movement to the client. This uses the speed and direction of travel for a smooth animation in the case of network delays.
Players on the red team can move quicker than players on the blue team.
Whenever the server receives movement from a player, it checks the acceleration of the player. If the average acceleration is above the specified value, a warning is sent to the cheating player.
