A minimal Flappy Bird-style game implemented entirely in ARM64 assembly. This project demonstrates low-level game development concepts such as rendering, input handling, physics, and collision detection without relying on high-level abstractions.
- Basic Flappy Bird gameplay
- Rectangle-based rendering (no textures or sprites)
- Gravity and jump mechanics
- Procedurally generated obstacles
- Collision detection
- Score tracking
- Simple game loop using a fixed frame rate
- “Game Over” state
- Spacebar : Make the bird jump
-
Written in ARM64 assembly
-
Uses an external graphics/input library "raylib" (for functions like
InitWindow,DrawRectangle, etc.) -
Game state (position, velocity, obstacles, score) is manually managed on the stack
-
Rendering is done using simple colored rectangles:
- Bird: red square
- Obstacles: white vertical bars
-
Physics:
- Constant gravity
- Upward impulse on key press
- Velocity clamped to a maximum value
-
Obstacles:
- Move horizontally across the screen
- Recycled when off-screen
- Heights randomized using
rand
-
main.asm: Main game implementation including- Initialization
- Game loop
- Input handling
- Physics updates
- Collision detection
- Rendering
- Cleanup
You need:
- An ARM64-compatible assembler (e.g.,
clangon macOS) - A graphics library "raylib" providing the external functions used
Build using the bash file:
chmod +x assemble.sh
./assemble.sh
- No assets (images/audio) are used-everything is drawn procedurally.
- No menus, UI system, or restart logic is implemented.
- The project focuses on understanding low-level mechanics rather than polish.
- No sound effects or music
- No restart or menu system
- Hardcoded values for gameplay tuning
This is a small experimental project intended for learning and exploration of assembly-level programming in a game development context.
