| - **Test Inventory Behavior** Once you have added the ''Inventory'' behavior to your player, you have to associate the ''pickupSound'' variable of the ''Inventory'' component in the **Inspector** panel with a sound asset. You can use whatever sound effect you like. You just have to make sure that the sound file is somewhere under the Unity ''Assets'' folder so that you can browse to it. You can either fill in the value for the sound file by pressing the litle target circle next to the edit box of the ''Pickup Sound'' property, or you can drag a sound from the **Project** panel right into the edit box. After you have provided the sound, you should play the scene and make sure you hear it when the player runs into the objet. | - **Test Inventory Behavior** Once you have added the ''Inventory'' behavior to your player, you have to associate the ''pickupSound'' variable of the ''Inventory'' component in the **Inspector** panel with a sound asset.

| - **Make a Pickable Object Prefab** In order to create multiple instances of your object, that now includes a behavior for being picked up, you can turn it into a **Prefab**. In the **Project** panel, navigate to your ''VIEN'' folder and create a new sub-folder called ''Prefabs''. Open that empty folder. Now drag the working instance of your object in the scene into this ''Prefabs'' folder (you are essentially storing the complete configuration of your game object into a template kind of structure that Unity calls a **Prefab**). Change the name of your new prefab object in the **Projects** panel into ''PickableObject'' or something like that (notice that the name also changes up in the scene). Now you can drag this prefab into your scene as many times as you want to make multple copies of it. If you wish to change any properties in all of them simultaneously, you can select the prefab instead of an object instance and use the **Inspector** to edit a property that then gets propegated to all instances of that prefab. | - **Make a Pickable Object Prefab** In order to create multiple instances of your object, that now includes a behavior for being picked up, you can turn it into a **Prefab**.

| - **Add a Counter to Inventory** You should do this on your own. Maintain a state in the ''Inventory'' class that knows how many objects have been picked up. Display this number on the screen. To have a class write something onto the GUI, you override the ''void OnGUI()'' method of that class (inherited from ''MonoBehavior''. This method gets called whenever the GUI gets updated by Unity. Here is an example of that method being used to write a sample number on the GUI:<code cpp> | - **Add a Counter to Inventory** You should do this on your own.
