Often, the simplest inventory situation is to display text to tell players whether they are carrying a single item (or not). In this recipe, we'll add the ability to detect collisions with the star GameObject and add this to the SpaceGirl mini-game. We will also display an on-screen message stating whether a star has been collected or not:

At the end of the recipe, in the There's more... section, we'll learn how to adapt this recipe to maintain the Integer total for how many stars have been collected, for a version of the game with lots of stars to collect.
