Game Skill System
This skill provides comprehensive knowledge about implementing skill systems for turn-based strategy games, based on the Sango Infinity project.
Key Components
Skill Core Classes
- Skill: Defines skill properties and configurations
- SkillInstance: Handles skill execution and state
- SkillTimeline: Manages skill performance timing and events
- SkillTimelineInstance: Processes timeline events and time control
- SkillTimelineEvent: Base class for different skill event types
Event Types
- PlayAnimation: Plays character animations
- PlayEffect: Triggers visual effects
- PlaySound: Plays sound effects
- ExecuteDamage: Calculates and applies damage
- ExecuteOffset: Handles unit movement/displacement
- ExecuteEffect: Applies skill effects (buffs, debuffs)
- ShowText: Displays skill text messages
- CameraShake: Triggers camera shake effects
Range Calculations
- Ring: Circular area around target
- DirectionLine: Linear area in a specific direction
- Spiral: Expanding spiral pattern
- Fan: Cone-shaped area
- Rectangle: Rectangular area
- Cross: Cross-shaped area
- Square: Square area
- Diamond: Diamond-shaped area
BUFF System
- Poison: Deals damage over time
- Burn: Deals fire damage over time
- Freeze: Immobilizes units
- Silence: Prevents skill usage
- Invincible: Grants temporary invulnerability
- Shield: Absorbs incoming damage
Implementation Guidelines
Skill Configuration
- Use JSON format for skill definitions
- Support MOD system for extensibility
- Include properties for damage, range, cost, and effects
Timeline System
- Define events with specific timestamps
- Use inheritance for event type specialization
- Separate configuration (SkillTimeline) from execution (SkillTimelineInstance)
Performance Optimization
- Reuse timeline instances to avoid frequent initialization
- Use efficient data structures for skill lookups
- Implement proper event sorting for timeline processing
Testing
- Create comprehensive test systems for skill functionality
- Test different skill combinations and edge cases
- Verify skill balance and performance
Common Issues and Solutions
Skill Execution Problems
- Check timeline event order and timing
- Verify skill effect initialization
- Ensure proper target selection logic
Performance Issues
- Optimize timeline event processing
- Reduce redundant calculations
- Use object pooling for frequently created objects
MOD Integration
- Ensure proper loading of MOD skill configurations
- Handle conflicts between base and MOD skills
- Maintain backward compatibility
Usage Examples
Creating a New Skill
- Define skill properties in JSON
- Implement any custom effects
- Configure timeline events for skill performance
- Test skill functionality and balance
Debugging Skill Issues
- Check skill configuration for errors
- Verify timeline event execution
- Test skill under different conditions
- Use logging to identify problem areas
Optimizing Skill Performance
- Profile skill execution time
- Identify bottlenecks in timeline processing
- Implement caching for frequently used data
- Optimize event processing order
