2 different ways

Way one

• background is constantly moving when the player is moving

• put the speed at which the player is moving into a variable
• manipulate this variable to the background to move at a slower speed then the player moves
• background should move in the opposite direction as the player

Way two

• background only moves when character reaches the side of the screen and is continuing to move

• detect when the player reaches the side of the screen
• put the player speed into a variable
• manipulate this variable to the background to move at a slower speed then the player moves
• background should move in the opposite direction as the player
