Game: Simple RPG – Shahbaz Sekhon

This is my first attempt in making an RPG game and it’s systems. I used a Udemy tutorial make this game. This game was made using Scriptable Objects, Unity Actions and Events to separate logic from presentation, Singleton Pattern for the managers, Finite State Machines for Enemy AI, Interfaces like Idamageable, Unity’s new Input system.

Here are some of the features of this RPG.

Player Inventory

Player has an Inventory system. Using which the player can equip weapons, use items and discard items. The items in the Inventory system are based on Unity’s scriptable objects and are stackable.

Once quest is accepted, it shows up in Player’s quest panel along with quest status. Once quest is completed, it can be claimed leveling up the player and receiving quest item.

Combat FSM

The enemy AI uses a Finite State Machine. These are the states it has: Wander, Patrol, Chase and Attack. Player weapons have 2 types. Melee or Ranged. Ranged weapons use Mana. Player can swap between weapons through the inventory. Player can obtain weapons by killing enemies, completing quests or buying them at the shop.

Here’s an example of one of the FSM state. Chase.
