The M5ObjectManager is responsible for creating, destroying, updating, and searching for game objects. A game object is anything visible or invisible in the game. This could include the player, bullets, enemies, and triggers--the invisible regions in a game that cause events when collided with. The derived M5Stage classes will use the M5ObjectManager to create the appropriate objects for the stage. They can also search for specific game objects to update game logic. For example, a stage may search for a player object. If one doesn't exist, the manager will switch to the game over stage.

As seen in the previous diagram, our game will use components. This means the M5ObjectManager will be responsible for creating those as well.
