Create a Collectable Object

In my action game, you will need to collect different things for each level. For the level I'm creating at the moment, the player needs to collect the names of the parts of the book that Musashi wrote. Before each level, a brief synopsis of what happened during that time in Musashi's life will be given. The player must collect the objects pertaining to the things that happened during that point in his life. The player must collect these objects to be able to move on to the next level.
