Official Changelog

Forge 1.20.1 1.0.5

For Minecraft 1.20.1 / Forge.

This update syncs the Forge 1.20.1 branch with the latest 1.21.1 mainline fixes where applicable, including smoother RTS camera behavior, large-build stability, progression UI fixes, JEI overlay fixes, and safer container overlay behavior.

• Changed the release artifact naming format.

  • New file name: rtsbuilding-forge-1.20.1-1.0.5.jar
  • Version metadata is now unified as 1.0.5.

• Added and enabled Smooth RTS Camera by default.

  • Ported the render-frame RTS camera prediction from the 1.21.1 mainline.
  • Keeps the same server-authoritative tick/network split.
  • The setting remains user-toggleable.

• Improved large quick-build / shape placement performance.

  • Added batched non-fluid shape placement.
  • Server processes large placement jobs gradually instead of firing one packet/action per block.
  • Reduces lag spikes during large RTS builds.

• Fixed RTS render-buffer stability.

  • Boundary, ghost preview, hovered target, and chunk guide rendering now use private buffers.
  • Avoids conflicts with Minecraft’s shared render buffer lifecycle.

• Fixed progression / skill tree material display mismatch.

  • The UI now follows the server-synced cost table.
  • Fixes cases where the detail panel showed enough materials but unlock still failed.

• Improved progression node details UI.

  • Added a higher-layer details modal for materials and prerequisites.
  • Shows all required materials and unfinished prerequisites.
  • Allows unlocking from the modal.

• Fixed JEI overlay blank / invisible clickable area behavior.

  • JEI now uses the actual RTS overlay layout instead of old hard-coded bounds.

• Improved container RTS overlay behavior.

  • Bottom import preview row reduced from five + slots to two.
  • Added Shift In toggle.
  • Shift import is disabled by default so normal container Shift-transfer works unless the player opts in.

• Improved linked-storage tool mining.

  • Remote tools are matched by full stack prototype instead of item id only.
  • Mutated tool stacks are refunded after mining or aborting.
  • Helps protect modded electric/NBT tools.

• Fixed Mod Menu / config save crash.

  • Progression and survival settings are saved through a single batched config write.
  • Save failures are handled with a message instead of a crash.

• Synced more RTS UI and control fixes.

  • Configurable pan-drag X/Y inversion settings.
  • High UI-scale layout fixes.
  • Camera-centered 3x3 chunk guide display with player-height Y.
  • Overlay and storage workflow cleanup.

Validation:

• Forge 1.20.1 jar task passed.
• Output verified: rtsbuilding-forge-1.20.1-1.0.5.jar.
