+# Acceptance Criteria: Base Character with Dialogue System
+
+## Overview
+This document defines the acceptance criteria for implementing a base character scene with dialogue functionality in Godot. The implementation should allow characters to have dialogue lines that can be triggered programmatically.
+
+## Requirements
+
+### 1. Base Character Scene
+- **Feature**: Create a base character scene with Polygon2D sprite
+- **Acceptance Criteria**:
+  - Scene file `scenes/base_character.tscn` exists
+  - Contains a Polygon2D node as the character sprite
+  - Character has appropriate positioning and scaling
+  - Scene can be instantiated in other scenes
+  - Scene includes necessary child nodes for dialogue system integration
+
+### 2. Dialogue Entity
+- **Feature**: Implement dialogue entity that can be triggered programmatically
+- **Acceptance Criteria**:
+  - Dialogue entity can be attached to any character node
+  - Can be triggered via a public method call
+  - Accepts text content and duration parameters
+  - Supports programmatic triggering without user input
+
+### 3. Visual Dialogue Box
+- **Feature**: White dialogue box that animates in when triggered
+- **Acceptance Criteria**:
+  - Dialogue box appears above character when triggered
+  - Animates in with smooth transition (fade/slide)
+  - Has white background with appropriate styling
+  - Properly positioned relative to character
+  - Resizes based on text content
+
+### 4. Text Reveal Animation
+- **Feature**: Text revealed one character at a time
+- **Acceptance Criteria**:
+  - Text appears character-by-character with delay
+  - Each character reveal has consistent timing
+  - Text is properly formatted and readable
+  - Animation can be configured with different speeds
+
+### 5. Duration Handling
+- **Feature**: Dialogue box closes after specified duration
+- **Acceptance Criteria**:
+  - Dialogue automatically closes after duration ends
+  - Smooth animation out when closing
+  - Duration parameter is configurable
+  - Can handle zero or negative durations appropriately
+
+### 6. API Interface
+- **Feature**: Clean public API for dialogue interaction
+- **Acceptance Criteria**:
+  - Public method to trigger dialogue: `trigger_dialogue(text, duration)`
+  - Method returns immediately after triggering
+  - No blocking operations during animation
+  - Proper error handling for invalid parameters
+
+### 7. Test Scene
+- **Feature**: Single character automatically triggering a single dialogue line
+- **Acceptance Criteria**:
+  - Test scene file `scenes/test_dialogue.tscn` exists
+  - Contains one base character instance
+  - Dialogue is automatically triggered on scene load
+  - Demonstrates complete functionality (show, reveal, hide)
+  - Scene runs without errors
+
+## Technical Specifications
+
+### File Structure
+```
+scenes/
+├── base_character.tscn
+└── test_dialogue.tscn
+
+scripts/
+├── dialogue_system.gd
+└── base_character.gd
+```
+
+### Dialogue System Components
+1. **DialogueBox**: Visual UI element for displaying dialogue
+2. **TextRevealer**: Handles character-by-character text animation
+3. **AnimationController**: Manages show/hide animations
+4. **CharacterDialog**: Interface for character-to-dialogue communication
+
+### API Methods
+```gdscript
+# In base_character.gd or similar
+func trigger_dialogue(text: String, duration: float) -> void:
+    # Triggers dialogue with specified text and duration
+    
+# In dialogue_system.gd  
+func show_dialogue(text: String, duration: float) -> void:
+    # Internal method to display dialogue UI
+```
+
+### Animation Requirements
+- **Show Animation**: 0.3 second fade/slide in
+- **Text Reveal**: 0.05 second per character
+- **Hide Animation**: 0.2 second fade out
+- **Duration**: Default 3 seconds if not specified
+
+## Success Metrics
+
+### Functional Tests
+1. [ ] Base character scene loads without errors
+2. [ ] Dialogue box appears when `trigger_dialogue()` is called
+3. [ ] Text reveals character-by-character with correct timing
+4. [ ] Dialogue box closes automatically after duration
+5. [ ] Test scene demonstrates complete workflow
+6. [ ] API methods can be called from other scripts
+
+### Performance Tests
+1. [ ] No frame drops during animation sequences
+2. [ ] Memory usage remains stable
+3. [ ] Animation timing is consistent across different hardware
+
+### Compatibility Tests
+1. [ ] Works with existing Godot 4.x projects
+2. [ ] Compatible with different character positioning
+3. [ ] Handles various text lengths appropriately
+4. [ ] Works with different duration values
+
+## Non-Functional Requirements
+
+### Code Quality
+- [ ] Well-documented code with comments
+- [ ] Clean, maintainable code structure
+- [ ] Follows Godot coding conventions
+- [ ] Proper error handling and validation
+
+### User Experience
+- [ ] Smooth animations without jank
+- [ ] Clear visual feedback during dialogue
+- [ ] Responsive interface
+- [ ] Accessible text formatting
+
+## Dependencies
+- Godot 4.x engine
+- Standard Godot 2D node types (Node2D, Control, Label)
+- AnimationPlayer or Tween for UI animations
+- Timer for duration handling
+
+## Acceptance Process
+1. Review code implementation against these criteria
+2. Run test scene to verify functionality
+3. Confirm all acceptance tests pass
+4. Validate API usability and documentation
+5. Ensure no breaking changes to existing systems
