Introduction

Potions often provide various benefits to the player or game characters, such as healing, enhancing abilities, or granting temporary buffs.

Item Pickup Component

The ItemPickupComponent is a crucial part of the game's code responsible for handling the pickup of items like potions. This component is associated with entities that represent items on the game map. When a player or character comes into contact with an item, such as a potion, this component triggers the pickup action.

The process of picking up potions is facilitated by the ItemPickupComponent, which is associated with entities representing potions. When a collision occurs between a companion entity and a potion entity, the ItemPickupComponent triggers the pickup action. This action effectively removes the potion from the game world and allows players or characters to benefit from its effects.
