|
> I've created a comprehensive Three.js animation system for Owen that implements the state machine and animation handling described in your brief. Here are the key architectural features:
|
|
|
|
## **Clean Architecture Principles:**
|
|
|
|
### **Dependency Injection:**
|
|
|
|
- `OwenAnimationContext` receives its dependencies (mixer, factory, etc.) through constructor injection
|
|
- State handlers are injected with the context they need
|
|
- Animation loaders are injected into factories
|
|
|
|
### **Factory Patterns:**
|
|
|
|
- `AnimationClipFactory` - Creates animation clips with proper metadata parsing
|
|
- `StateFactory` - Creates state handlers dynamically
|
|
- `OwenSystemFactory` - Main factory that assembles the entire system
|
|
|
|
### **State Machine Implementation:**
|
|
|
|
- Each state (`Wait`, `React`, `Type`, `Sleep`) has its own handler class
|
|
- States manage their own entry/exit logic and transitions
|
|
- Emotional transitions are handled with proper animation sequencing
|
|
|
|
## **Key Features:**
|
|
|
|
1. **Animation Naming Convention Parser** - Automatically parses the naming convention from your brief (e.g., `wait_idle_L`, `react_angry2type_an_T`)
|
|
|
|
2. **Emotional State Management** - Handles emotional transitions like angry typing or shocked reactions
|
|
|
|
3. **Nested Animation Support** - Supports the nested sequences described in your brief
|
|
|
|
4. **Activity Monitoring** - Automatically transitions to sleep after inactivity
|
|
|
|
5. **Message Analysis** - Analyzes user messages to determine appropriate emotional responses
|
|
|
|
6. **Clean Separation of Concerns:**
|
|
- Animation loading is separate from clip management
|
|
- State logic is isolated in individual handlers
|
|
- The main context orchestrates everything without tight coupling
|
|
|
|
## **Usage:**
|
|
|
|
The system is designed to be easily extensible. You can:
|
|
|
|
- Add new states by creating new handler classes
|
|
- Modify emotional analysis logic
|
|
- Swap out animation loaders for different formats
|
|
- Add new animation types by extending the factory
|
|
|
|
The code follows the workflows described in your brief, handling the transitions between Wait → React → Type → Wait states, with proper emotional branching and nested animation support.
