Unity RPG Course - Section 3 - Modifiers And Abilities

Welcome to Section 3 of the Unity RPG course – the full course is part of a Kickstarter campaign which was over 200% funded. You will benefit from the fact we have already taught over 360,336 students game development, many shipping commercial games as a result.

Customise character abilities, weapons, characters and enemies. This includes multiple damage types, modifiers, sounds, animations. By the end you can create your core combat experience.

You're welcome to download, fork or do whatever else legal with all the files! Please note that future sections contain assets with commercial use restrictions. The real value is in our huge, high-quality online tutorials that accompany this repo. You can check out the course here: Unity RPG

How To Build / Compile

This is a Unity project. If you're familiar with source control, then "clone this repo". Otherwise download the contents, and navigate to Assets > Levels then open any .unity file.

This branch is the course branch, each commit corresponds to a lecture in the course. The current state is our latest progress.

24 Player Choice In Combat

1. What are the choices the player can make in your combat?
2. Types of Special Abilities
3. Where to start with implementation

25 RPG Special Abilities System Overview

1. Abilities require serialisable data AND behaviour
2. We can only serialise MonoBehaviours via prefab or scene
3. This causes more contention on those files, and is wrong place
4. A ScriptableObject moves ability config data to a .asset file
5. ... but SOs cannot interact with the world
6. so the Ability also needs a MonoBehaviour
7. One ability can have multiple configs
8. Therefore make the config add the behaviour component at runtime.

26 Storing Special Ability Config data

1. Setup an 'ISpecialAbilty' interface
2. Use an abstract class to create SpecialAbilityConfig
3. Inherit 'PowerAttackConfig' from this new abstract class
4. Provide right-click asset menu to create new special ability.

27 Making A Class Single Purpose

1. Remove pointsPerHit from our Energy component
2. Move right-click handling to the Player
3. Prepare to read energy cost from special ability.

28 Implementing Power Attack Behaviour

1. Fix a bug with our AudioTrigger component
2. Make it possible for the player to equip several abilities
3. Use a protected property to reference behaviour component
4. Use this property to forward calls to Use() to the component.

29 Using Structs For Parameter Sets

1. Combine top-level special ability code into one file
2. Create a struct to pass ability use parameters
3. Finish Power Attack behaviour inc energy cost.

30 Create An Area Of Effect Ability

1. Describe your challenge
2. Introduce Physics.ShpereCastAll() API
3. Demonstrate my Area Of Effect solution.
