Achievement System KonadoAchievement

Preface

KonadoAchievement is a lightweight, data-driven achievement system plugin designed for Konado. It provides complete functionality including unlocking, progress tracking, popup notifications, and an achievement panel. It can be used together with Konado or run independently.

Configuration File

The achievement system uses a JSON configuration file to define achievements. The default path is res://addons/konado_achievement/data/achievements.json, and another path can be configured in KND_AchievementManager.

Example configuration file structure:

{
  "achievements": [
    {
      "id": "first_blood",
      "name": "First Encounter Chapter",
      "description": "Unlock the first main story branch.",
      "icon": "",
      "hidden": false,
      "category": "story",
      "points": 10,
      "conditions": {
        "type": "counter",
        "target_key": "story_branch_unlocked",
        "target_value": 1
      }
    }
  ]
}

Configuration Options (Optional)

In KND_AchievementManager, you can configure the following properties:

• config_path: Path to the achievement configuration file
• save_path: Path for saving achievement progress
• popup_duration: Display duration of the achievement unlock popup notification
• popup_position: Popup notification position (top_left, top_right, bottom_left, bottom_right)

::tip This part may be refactored in the future to provide more flexible configuration options. ::

Core Features

Achievement Unlocking

The achievement system supports two unlocking methods:

1. Direct unlock: Unlock achievements directly through the API
2. Conditional unlock: Automatically unlock achievements when specific conditions are met

Progress Tracking

The system supports two types of progress tracking:

1. Counter: Unlock when an accumulated value reaches the target value
2. Flag: Unlock when a flag is set to a specific value

Notification System

When an achievement is unlocked, the system displays a popup notification containing the achievement name, description, and icon.

Achievement Panel

Provides a panel that can display all achievements, including unlocked and locked achievements, as well as unlock progress.
