Core game mechanics that go beyond pure graphics or audio. These examples demonstrate fundamental patterns – collision detection, movement, and interactive logic – that you will reuse in every game project.

Examples

Example	Difficulty	Description
collision_demo	Intermediate	Bounding-box collision detection between multiple sprites
panel_hud	Intermediate	9-slice HUD + dialog box on one BG layer (the panel module)
game_skeleton	Intermediate	The smallest complete game: title → play → game-over state machine

Key Concepts

Bounding-box collision: compare rectangle edges to detect overlaps
The SNES has no hardware collision detection – it must be done in software
Efficient collision checks matter because the 65816 CPU is slow at 32-bit math

After completing the graphics and input examples, study collision_demo to see how sprites, input, and math come together into interactive gameplay.
