Skilltree Wurt

Based on game build 722832 | Last updated: 2026-04-22

Overview

skilltree_wurt is a data configuration file that defines the complete skill tree structure for the character Wurt. It provides a factory function BuildSkillsData that generates skill node definitions with positions, group assignments, tags, and activation/deactivation callbacks. This file is consumed by the skill tree UI system to render and manage Wurt's unlockable abilities across three categories: Amphibian, Swampmaster, and Allegiance.

Usage example

local SkillTreeFns = require("scripts/skilltree_functions")
local WurtSkillTree = require("prefabs/skilltree_wurt")

local skillData = WurtSkillTree(SkillTreeFns)

-- Access skill definitions
local skills = skillData.SKILLS
local orders = skillData.ORDERS

-- Access individual skill node
local amphibianSanity = skills.wurt_amphibian_sanity_1
print(amphibianSanity.pos)  -- {x, y} coordinates
print(amphibianSanity.group)  -- "amphibian"
