Inventory and Hotbar
The Inventory
class and InventoryInterface
manage a player's item collection in the game. They handle adding, removing, and using items, as well as checking inventory status. In future, this InventoryInterface can be generalised to model all containers (e.g. chests etc.) in the game and the current Inventory
class can be abstracted as a base class for all containers (ie useItem
would be moved to a concrete subclass, since a general container would not support this functionality).
Next, the PlayerInventoryDisplay
handles the UI for the items. This is what users can interact with during gameplay. The display can be toggled on or off by pressing E
. Items can be used from the inventory by clicking them (currently just removes item with no effect on game), and items can be picked up from the game via button press P
. Players can use items from either the Hotbar or PlayerInventoryDisplay
by clicking on the item. Dialogue will appear for these items displaying how much usage items have left. However, this display players cannot use certain items such as defence and attack potions outside of combat.
CombatInventoryDisplay
an inventory extending from PlayerInventoryDisplay
is a special inventory that can be toggled on and interactive in `CombatScreen allowing players to use items during combat (which is considered a combat move). the ability to use defence and attack potions will be permitted.
