RailOptimization

RailOptimization v1.5

RailOptimization optimizes powered rail and activator rail redstone updates by replacing repeated vanilla recursive scans with a faster cached propagation path.

What's New

• Sloped powered rails are now included in the optimized batch propagation path. Long rail lines containing ascending or descending rails no longer fall back to the slower vanilla propagation step after a rail state changes.
• Direction-sensitive slope traversal improves correctness for asymmetric rail layouts, including continuous slopes, descent-to-ascent chains, and diagonal zigzag-style rail paths.
• Rail neighbor notification order has been adjusted to preserve vanilla-like update behavior, including observer and BUD-sensitive setups around rail endpoints.
• The optimized path keeps curved rails and unsupported shapes guarded, falling back to vanilla behavior where the fast path is not safe.

Fixes

• Fixed update-order differences that could prevent observer/BUD behavior from matching vanilla in some rail endpoint update chains.
