Completing the player's and the background's components

All the game objects are reliant upon or react to the player. For example, the aliens will spawn, chase and shoot relative to the player's position. Even the background will take its que for which way to scroll based on what the player is doing. Therefore, as mentioned previously it makes sense to get the player working first.

However, remember that using the Entity-Component pattern will mean that some of the components we code for the player will also be used when we implement some other game objects.

As we code all the player and background components I will make it clear what is new code and what we coded back in the Coding the player's...
