Ultimate Skill/Tech Tree System

Ultimate Skill Tree Maker is a complete tech tree (skill tree) solution for UGUI.

You can visually create nodes, edit relationships, and save them as ScriptableObjects in the built-in Tech Tree Editor; then sync them to the scene UI with one click, and automatically rebuild connections based on the relationships. At runtime, the ConditionUnlockManager manages unlock logic, unlockable status, save/load, and multi-tree switching. It supports tiered research, resource deduction, and an info panel.

Core Features

Visual Editing

Create/drag nodes, connect links, box selection, and batch drag; canvas grid snapping (Off / 20 / 50 / 100 px); "Clear All Links" to remove all links with one click; wider node panel with foldout sections (Basic Info / Canvas & Prerequisites / UI Unlock Events / Dev Info); Levels always visible; dev progress and notes on nodes; canvas color by progress (editor‑only workflow).

UI Workflow
Sync node layout to the target container; auto‑rebuild UI lines from relationships.

Multi‑Tree Support
Multiple TechTreeNodesSO assets bound to independent panels (TechTreePanelBridge).

Multi‑Level Nodes
Each tier can configure resource costs, research duration, and localized name/description; supports initial unlockable and multiple upgrades.

Tech Categories
Global TechCategoriesSO and Category Editor; node UI / info panel can display category name and icon (shared across trees).

Research System
Per‑tier research duration (0 = instant unlock); global research speed multiplier, concurrent research slot limit, pause/resume API; node research progress bar, slot‑full indicator; effective research time shown in the info panel.

Info Panel
Required resources / research time; dynamic prerequisite list (localized names; green = unlocked, red = locked).

CSV Workflow
Batch import with fixed column order; export current tree; auto‑fill prerequisite relationships.

Localization Support
Based on Unity Localization; after language switching, node, category, and panel texts update automatically.

Event Extension
Node‑level and global unlock/reset events for integrating sound effects, quests, achievements, save/load.

Resource Costs
Built‑in native resource pool (deduct cost, disable when insufficient, refund on reset) or external system via SetResourcesSufficient.

Ready to Use
