Build Your First 3D Game with Godot

This complete teaching resource guides students through the full process of creating a First-Person Shooter (FPS) game using Godot 4.

Designed for KS3, KS4, IGCSE Computer Science, IB DP Computer Science, and STEAM/ICT pathways, the resource develops programming, game design, problem-solving, and computational thinking through a highly structured, practical project.

Each lesson includes clear learning objectives, teacher guidance, and a progressive build-up of skills from basic movement to AI mobs, scoring, sound design, and exporting a fully playable game.

Perfect for classroom teaching, befor or after school game development clubs, STEAM programmes, and independent learning.

A complete sequence of 16 lessons:

1. Getting set up
2. Coding camera rotation
3. Limiting the mouse
4. Coding ground movement
5. Coding the jump and fall
6. Creating the level
7. Coding the shooting mechanics
8. Creating the mob (enemy)
9. Getting the mob to follow the player
10. Damaging and killing the mob
11. Spawning mobs continuously using spawners
12. Scoring system
13. Adding sounds
14. Setting up the kill plane
15. Adding visual effects & refining the overall level
16. Exporting the game
