Super Vault Boy

A technical demonstration showcasing advanced 3D character control systems in Godot 4.4, featuring fluid camera movement (built upon my third-person camera controller that provides Mario Odyssey-style camera functionality), state-driven animations, and reactive facial expressions. 

Core Systems

State-Driven Animation System 

Implemented a BlendSpace2D-based state machine that seamlessly transitions between player states: 

• Ground Movement: Idle → Walking → Running with smooth speed-based blending 
• Aerial States: Jumping → Falling → Landing with proper apex detection 
• Smart Transitions: Context-aware state changes that feel natural and responsive 

Dynamic Facial Animation System 

Created a texture-swapping facial controller that responds to gameplay: 

• Facial expressions automatically change based on player state 
• Neutral (idle), Smug (running), Shocked (jumping/falling) 
• Easily extensible system supporting 8+ expressions 
• Material override system for performance-efficient texture changes 

Professional Blender-to-Godot Pipeline 

• Custom character modeled and rigged in Blender 
• Animation retargeting in Godot 4.4 for seamless integration 
• Optimized mesh and material setup for real-time rendering 

Animation Architecture 

The UnifiedPlayerController uses a two-axis BlendSpace2D system: 

• X-axis: Movement speed (Idle → Walk → Run) 
• Y-axis: Vertical state (Ground → Jump Start → Jump → Fall) 
• Smooth interpolation between animation states prevents jarring transitions 

Modular Effect System 

Auto-discovery system for audio and particle effects: 

• Jump, land, and run effects tied to state changes 
• Continuous effects (running particles) vs one-shot effects (landing) 
• Decoupled architecture for easy expansion 

State Machine Design 

Clean separation of concerns: 

• State calculation logic 
• State transition handling 
• Animation blending system 
• Effect triggering 
• Facial expression management

Each system operates independently but coordinates through the state machine, making the codebase maintainable and extensible.
