Space Shooter

For my GSD 511: Game Development I course, we made a side-shooter project. I decided to stick with the space theme since I already had some space assets I created a while back and wanted to expand on them a little bit. I’m hoping to add some more quality of life features and some better balancing, but am currently hindered by some health issues.

In the current, not well-balanced, state it may only be possible to win using the weapon swapping. I wasn’t able to complete it with the starter weapon, but maybe I’m just bad at aiming :)

Controls

• Move with arrow keys
• Cycle through weapons with < and >

v1.0 Features - Lecture Version

• Data-Driven Design - uses a custom auto-loaded data_loader.gd script to pull game data from .csv files
  • uses a spreadsheet as a single source of truth
  • see Game Data Examples section for more details
• Equipable Weapons - a variety of weapons, each with different stats
  • NOTE: weapon firing / in-game model is not implemented at this point, just in-game data pulling and weapon label
• Enemies - a variety of enemies, each with different stats
  • NOTE: enemies are not yet implemented in game, just the data import and sprites

v2.0 Features - Lecture Version (+ Extra Content)

• Expanded Data-Driven Design - added handling for spawns.csv to define waves, and added score values to each enemy
• Weapon Firing - bullets spawn in front of player and travel towards enemy-side using the currently equipped weapon’s data
• Enemy Waves - enemies spawn on right side if the screen with y-position and time between spawns pulled from the wave data
  • enemies fly towards player-side using pulled enemy data
  • enemies are destroyed when they:
    • reach the other end of the screen -> player loses a life
    • run into the player -> player loses a life
    • take damage greater than or equal to their HP from the player’s bullets -> player gets the enemy’s point value added to their score
• More Weapon and Enemy Types - now have 5 weapons and 5 enemies
• Player Lives - player can take damage from enemies reaching the player side or running directly into the player
• Player Score - player gets points for each enemy killed (scores are defined in the enemy data)
• Win/Loss Screens - appropriate screens for when player loses (has 0 lives remaining) and wins (defeats the wave), with restart buttons to play again
• Weapon Swapping - player can cycle through every implemented weapon using the < and > keys

Game Data Examples

Weapons & Enemy Data

This data lives in a Google Sheet, which I export to .csv and drop into the project for data_loader.gd to read at runtime. The tables below are pulled directly from those exported files, so they’ll stay current as the sheet evolves. I’ve also linked the full .csv files as a downloadable reference.

Godot CSV Import Issue

This is how to fix the CSV data pulling if files cannot be found when exported to the web:

1. Check the Import tab (usually in the same pane as the Scene window)
2. If it’s showing CSV Translation, change it to Keep File (exported as is)
3. Re-Import
4. Repeat for each CSV file
