Extended Pistons

Extended Pistons 1.1.3

Version 1.1.3 is a bug-fix release for Minecraft 1.21.1, addressing redstone-block retraction and moving piston display names.

Changes

• Fix upward-facing sticky pistons getting stuck near the end of retraction when pulling a redstone block, potentially extending and retracting repeatedly.
• Fix the same self-powering issue affecting upward-facing normal pistons when pushing a redstone block.
• Prevent the power check from treating the block two spaces above an upward-facing piston base as an input. This stops a redstone payload in front of the head from repowering its own piston.
• Preserve external power handling, including power restored during retraction and quasi-connectivity from other directions.
• Fix moving piston parts displaying the internal translation key block.extendedpistons.movement_transaction. They now display Moving Extended Piston.
• Add six regression GameTests covering normal and sticky pistons, short and longer upward paths, horizontal sticky movement, and external power handling.

Compatibility

• Minecraft 1.21.1
