[ta-edu-course-survival-game] Chapter 2 — ScriptableObjects

Instructions.md

• Create ItemType.cs
• Make ItemType derive from ScriptableObject
• Add a string field called "DisplayName"
  • We could add more meta information (e.g., stats, description, icon, etc.), but we don’t need to at the moment
  • Each instance of ItemType will represent a type of item and will be referenced in our code instead of strings
  • But how do we create item types?
• Add the CreateAssetMenu attribute
  • Like components that derive from MonoBehaviour, scriptable objects don't support constructors and can't be instantiated with new
  • You can use ScriptableObject.CreateInstance
  • But the CreateAssetMenu allows you to create your scriptable object assets right from the Unity editor, which is what we want
• Change the string array in Inventory to an ItemType array
• Change the string field in InteractionHandler to ItemType
• Switch to Unity
• Create a folder called “Content”
• Create a new instance of ItemType for each item (Sword, Potion, Scroll)
• Update the scene and verify the behavior

Inventory.cs

public class Inventory : MonoBehaviour
{
  [SerializeField] private ItemType[] items;
}  

ItemType.cs

[CreateAssetMenu(menuName = "Game/Item Type")]
public class ItemType : ScriptableObject
{
  public string DisplayName;
}
