Avocado

Various studies applied to a platformer game in Unity, C#.

Rationale

This project was done for educational and entertainment purposes.

Also, it could help with assessing the quality of my code during interviews.

What I did

I applied my studies of the following resources:

• Book. Game Programming Patterns - Bob Nystrom

• Book. LevelUp! - Scott Rogers

  I am also a firm believer that almost ANYTHING can be made into gameplay

• Article. Unity — Project Structure Best Practices! - Samuel Asher Rivello

• Video. Math for Game Programmers: Building a Better Jump - at 2016 GDC talk, by Kyle Pittman

• Video. Math for Game Programmers: Juicing Your Cameras With Math - at 2016 GDC talk, by Squirrel Eiserloh

• Video. How to Make a Good 2D Camera - Game Maker's Toolkit

• Wwise

  • Documentation. Wwise Fundamentals

  • Video. Wwise Tutorial - Integrating Wwise Into Unity - Crosby Nelson

  • Video. Wwise Tutorial - Posting Events With Custom Scripts In Unity - Crosby Nelson

  • Video. Game Audio with Unity and Wwise Part 2: Let there be Sound! - Michael G Wagner

  • Video. Wwise Tutorial - Playing A Sound In Unity - Crosby Nelson

  • Video. Wwise-101 - Lesson 4 - Applying Distance Attenuation - Audiokinetic

Study results

There you can find examples of using the following:

• Throwing seed!
• Decoupling input handling from logic
• State design pattern for the character controller
  • Movement
    • Idle
    • Running
  • Jumping
  • Falling
  • Throwing seed

• Good project layout that supports project organization. It also makes sure that nothing unnecessary goes into the build (e.g. dependency on Unity's Editor library)
• Consistent code formatting
• A trick with not instantiating projectiles more than once per avocado controller

• ⬆️ I got formulas of gravity and initial velocity for achieving a jump of specific duration and height
• Movement
  • Max movement speed
  • Acceleration speed
• Jumping
  • Slower horizontal acceleration while mid-air
  • Jump cutoff
  • Duration til reaching the top point of the jump
  • Higher gravity scale while falling
• Camera
  • Dead zone
  • Non-instant camera following
  • Lookahead
  • Pixel perfect
• Assists
  • Coyote time
  • Buffering inputs
  • Max falling velocity
• Juice
  • Camera Shake on fall. Used SimplexNoise to simulate Perlin noise
  • Particles
    • While running
    • On jump
    • On grounded
  • SFX using Wwise
    • Footsteps
    • On jump
    • On grounded with different volume
    • Throwing
    • On seed colliding with terrain
• Enemies
