The only skill tree asset that makes sense: place nodes on a grid, auto-generate edges, and ship RPG progression with levels, costs, saves and events.Skill Tree Pro is the skill tree asset that just makes sense: place your nodes on a grid and the tree connects itself. Build interactive skill trees, talent trees, upgrade maps, perk screens and ability unlock menus without manually wiring every edge.✨ Drag-and-Drop SetupAdd skill nodes to the tree, move them into position, and let Skill Tree Pro automatically generate the edges between adjacent nodes.🎨 Easy UI CustomizationCustomize icons, colors, locked/unlocked states, descriptions, level text, cost display, edge colors and button feedback to match your game's style.🔌 Connect Your Own SystemsSkill Tree Pro does not force a wallet, save backend or ability system on your project. Use the provided events, result objects and validation hooks to connect your own save system, currency system, stats, abilities, quests, achievements or server checks.🧩 Inspector or Code WorkflowHook up functions directly in the Inspector with UnityEvents, or drive the tree through code with APIs for unlocking, refunding, querying, saving, loading, refreshing and changing edges at runtime.⬆️ Multi-Level SkillsCreate skills that can be purchased once or upgraded through multiple levels, each with its own cost and optional rules for unlocking neighboring skills.💰 Multi-Currency CostsUse simple one-currency costs or structured multi-currency costs such as gold, gems, stars, tokens, fragments or any custom currency IDs your game uses.🔎 Pan and ZoomMove around the tree and zoom in or out with the included UI setup, making large progression maps easier to explore.⚙️ Simple First, Flexible LaterStart with a basic tree in minutes, then scale into more complex use cases with reusable SkillDefinition assets, manual edge overrides, hidden branches, refunds, respecs, custom validation and runtime graph changes.🤖 AI-Ready DocumentationNeed help integrating or extending the asset?
