# 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
