Nexus: The Progression & Skill Tree Engine

Stop Building Systems. Start Designing Progression.

Every great RPG needs a deep and satisfying progression system to keep players hooked. But building these systems from scratch is a huge architectural challenge. You have to create skill trees, track achievements, and manage leveling curves, all while making sure it's easy for you to balance and expand

Nexus is a complete, production-ready engine that solves this problem. It's a data-driven framework that handles all the complex logic for skill trees, achievements, and player leveling. This allows you to stop coding systems and start designing the fun part: the player's journey.

Core Features

• Designer-Friendly Skill Trees: Build complex, branching skill trees as ScriptableObject assets. You can define skill costs, level requirements, and prerequisites directly in the Unity Inspector with no code required.
• Multi-Criteria Achievements: Create achievements with one or multiple objectives. The event-driven AchievementTracker listens for any game event you define, like "OnGoblinKilled" or "OnItemCrafted," and automatically updates progress.
• Data-Driven Leveling Curve: Use a simple AnimationCurve in a ScriptableObject to visually design your entire game's XP progression from level 1 to 100.
• Flexible Reward System: Grant meaningful rewards for unlocking skills or completing achievements, including perks, stat bonuses, or any other custom reward you can imagine.
