Changelog

All notable changes to AtlantumReactor will be documented in this file.

[4.0.11] - 2026-01-07

Changed

• All items now appear in unified "Modded" build menu tab
• Updated dependency on TechtonicaFramework 1.2.0

Fixed

• Build menu organization for cleaner UI

[4.0.10] - 2025-01-06

Fixed

• Moved to Modded category - Reactor unlock now appears in the Modded tech tree tab instead of vanilla Energy category
• Fixed vanilla tech tree conflicts - No longer overlaps with HVC Reach IV and other vanilla items
• Added TechtonicaFramework dependency - Uses ModdedTabModule for proper tech tree placement

Changed

• Research tier set to Tier7 (endgame)
• Tree position set to 100 for clear visibility in Modded tab

[4.0.0] - 2025-01-04

Changed - COMPLETE REWRITE

• Fixed fundamental architecture - Now properly extends PowerGeneratorDefinition instead of MemoryTreeDefinition
• Proper power generation - Uses RuntimePowerSettings with negative kWPowerConsumption for generation
• Working fuel system - Accepts Atlantum Mixture Brick and Shiverthorn Coolant as fuel
• Fuel consumption - Proper fuel burn rate tied to power generation

Added

• Green visual tint - Bright radioactive green material on reactor model
• Emission glow - Green emissive shader effect for visibility
• OmniseekerPlus integration - AtlantumOreVein scanning support
• Configurable power output - 1000kW default, adjustable via config
• Fuel burn rate config - Adjustable fuel consumption speed

Technical Details

• Uses isGenerator = true flag for proper power network integration
• MaterialPropertyBlock for shader modifications (performance-friendly)
• Harmony patches for:
  • Power generation (ReactorPowerPatches)
  • Fuel acceptance (AcceptCustomFuels)
  • Visual effects (ReactorVisualPatches)
  • Omniseeker support (OmniseekerPatches)

Fixed

• Reactor now actually generates power (was completely non-functional before)
• Fuel items can now be inserted via inserters
• Power shows correctly in power network UI
• Works with existing power infrastructure

[3.0.0] - Previous

Known Issues (Now Fixed)

• Extended MemoryTreeInstance instead of PowerGeneratorInstance
• Had no fuel inventory system
• Had no actual power generation capability
• Items couldn't be inserted into reactor

[1.0.0] - Initial Release

• First attempt at Atlantum Reactor
• Based on Memory Tree model (incorrect approach)
