Official Changelog
NeoForge 1.21.1 1.0.5
For Minecraft 1.21.1 / NeoForge.
This update focuses on RTS camera smoothness, large-build stability, storage/overlay workflow fixes, progression UI correctness, and JEI compatibility.
Changed the release artifact naming format.
- New file name:
rtsbuilding-neoforge-1.21.1-1.0.5.jar - Version metadata is now
1.0.5.
- New file name:
Added and enabled Smooth RTS Camera by default.
- Absorbed the smooth-camera idea from community PR #15 by SOLR98.
- Camera movement now uses render-frame visual prediction for much smoother motion.
- Tick/network logic still remains server-authoritative.
- The setting can still be disabled in RTS settings.
Partially adopted the freecam input-freeze part of PR #15.
- While RTS mode is active, player movement input is temporarily frozen during player tick.
- This helps prevent WASD / Space / Shift from moving the player body while controlling the RTS camera.
- Broader risky PR changes were not merged wholesale.
Improved large quick-build / shape placement performance.
- Added batched block placement payloads for normal non-fluid shape builds.
- Server now processes large placement jobs gradually with a per-tick budget.
- This reduces lag spikes when building large areas.
- Fluid placement still uses the old path to avoid changing bucket/fluid side effects.
Fixed crashes and instability around RTS boundary/chunk rendering.
- RTS boundary, ghost preview, hovered target, and chunk guides now use private render buffers.
- No longer uses Minecraft’s shared main
BufferSourcein the render stage. - This should avoid render-pipeline conflicts in vanilla/NeoForge and with render optimization mods.
Fixed progression / skill tree material display mismatch.
- The client UI now uses the server-synced cost table after progression state arrives.
- Fixes cases where the UI showed enough materials, but unlock still failed.
Improved progression node details UI.
- Material / prerequisite details are now shown in a higher-layer modal.
- The modal lists required materials, whether the player has enough, and unfinished prerequisites.
- Unlock can be attempted directly from the detail modal.
Fixed JEI blank / invisible clickable area caused by RTS overlay geometry.
- JEI now asks the actual RTS overlay layout for extra areas and clickable ingredients.
- This fixes old hard-coded overlay bounds reserving space where no RTS UI is visible.
Improved container RTS overlay behavior.
- Reduced the bottom import preview row from five
+slots to two. - Added a
Shift Intoggle. - Shift-click / Shift-drag importing into linked RTS storage is now disabled by default.
- When enabled, the toggle turns green; when disabled, normal container Shift-transfer works again.
- Reduced the bottom import preview row from five
Improved linked-storage tool mining.
- RTS mining can use tools from linked storage more safely.
- Tool matching now uses the full ItemStack prototype instead of item id only.
- Mutated tools are returned after mining, reducing risk for GTCEu/GregTech-style electric or NBT tools.
Fixed Mod Menu / config save crash.
- Survival/progression settings are now saved in one batched config write.
- Runtime save failures are caught and reported instead of crashing from the Save button.
Added several RTS control and UI refinements.
- Added configurable pan-drag X/Y inversion settings.
- Improved selected-item hover/status cleanup.
- Improved high UI-scale behavior for quick-build and settings panels.
- Chunk guide rendering now uses the RTS camera X/Z center with player Y height.
Validation:
- NeoForge 1.21.1
jartask passed. - Output verified:
