Base class PickupItem

We need to define how a pickup item looks in code. Each pickup item will derive from a common base class. Let's construct the base class for a PickupItem class now.

The PickupItem base class should inherit from the AActor class. Similar to how we created multiple NPC blueprints from the base NPC class, we can create multiple PickupItem blueprints from a single PickupItem base class, as shown in the following screenshot:

Once you have created the PickupItem class, open its code in Visual Studio.

The APickupItem class will need quite a few members, as follows:

• An FString variable for the name of the item being picked up
• An int32 variable for the quantity of the item being picked up
• A USphereComponent variable for the sphere that you will collide with for the item to be picked up
• A UStaticMeshComponent variable to hold the actual Mesh
• A UTexture2D variable for the icon that represents the item
• A pointer for the HUD (which we will initialize later)

This is how the code in PickupItem...
