Processing a hit is a very wide concept. It basically depends on the type of application that you are building. For instance if your application is a CAD system, you might want to retrieve on screen the properties of the object that you picked to edit them. You might also want to move the object or change its dimensions. In contrast, if you are developing a game, you could have selected the next target that your main character has to fight. We will leave this part of the code for you to decide. Nevertheless, we have included a simple example in the next Time for action section where you can drag-and-drop objects, which is one of the most common interactions you could have with your scene.
