Where to Play

You can play my assignment by:

• Opening it in Unity 2022.3.10f1
• Compiling the project yourself
• Extracting the already built game in ./Output/cs50_space_shooter.rar
• Via Itch here: itch - edx-space-shooting -- This webgl version doesn't have an exit button

Game Features

• Object Pooling -- Used for explosion particles, enemies and background elements
• FSM with an easy-to-use Custom Editor interface
• Tag Logging -- I can log stuff using some tags so I can enable\disable logs based on Tags (Custom Editor)
• Enemies Spawning with difficulty progression and pooling
• Dynamic Background -- Created by spawning (and pooling) star particles and background meteors
• Custom build system -- In order to version each update and simplify the build process to multiple platforms

Now I'm going to describe some infra stuff I created in order to handle FSM, Building, Spawning, Pooling and Sounds

Editor Scripts

Finite State Machine (FSM)

I've created an FSM system with a CustomEditor interface so I can register\remove elements via interface:

• FSM Controllers
• FSM States
• FSM Events

Altering the entries list seem in this picture would also change the ENUM related to it, recompiling the code

To use this, simply add a FSMStateController component to any GameObject, register its states and you're ready to go

Existing states in this project

• Application: PREPARING, IDLE, MENU, GAME, PAUSED, PLAYER_SELECTOR, GAME_OVER
• Background: IDLE
• Player: PREPARING, IDLE, GAME, PLAYER_SELECTOR, PAUSED
• Enemy:PREPARING, IDLE
• Input: IDLE
• Gun: IDLE
• MenuController: IDLE, MENU, GAME, PAUSED, PLAYER_SELECTOR, GAME_OVER

Pooling System

I've created a simple pooling system so I can recycle common elements spawning in the scene

• Enemies
• Explosions
• Guns

• 

Enemy Spawning and difficulty progression

The enemy spawning system has 3 configurable via inspector areas:

• Spawn area - Where the enemies can be spawned
• Destination area - Where the spawned enemies can head to
• Destroy area - The area all enemies should keep inside. Going outside of it will re-enqueue the enemy to the pool

• 

Tag Logging

Using the same infra code from FSM Custom Editor, I've created a simple but elegant Logging System

• 

Custom Build System

Lastly, I've created a build system that can manage versions and create a CHANGELOG.md for each build
