Hardcore Questing Mode: Moveable Quest Gates

A Minecraft mod that lets Hardcore Questing Mode quest gate blocks move with vanilla pistons while preserving their portal data.

Features

• Moveable Quest Gates: Allows hqm:quest_portal blocks to be moved by vanilla pistons.
• Sticky Piston Support: Sticky pistons can push and retract quest gates.
• Normal Piston Support: Normal pistons can push quest gates.
• All Directions: Movement works in all six piston directions.
• Vanilla Limits Preserved: The normal 12-block piston limit and unrelated piston rules still apply.
• Scoped Behavior: Other tile entity blocks remain unpushable unless vanilla already allows them.
• HQM Integration: Targets Hardcore Questing Mode 4.4.4 quest portals.

Aggressive Coremod Approach

This mod is intentionally aggressive and is meant for controlled niche modpacks, not broad public-pack compatibility.

• Vanilla Piston Patch: Uses UniMixins to patch vanilla piston logic directly.
• Custom Movement Path: Replaces the vanilla piston move routine only when an HQM quest portal is part of the piston move.
• Tile Entity Override: Adds custom data storage to vanilla moving piston tile entities so HQM portal NBT survives piston animation.
• Targeted Risk: The aggressive behavior is scoped to hqm:quest_portal; unrelated piston moves should keep vanilla behavior.
• Compatibility Target: Built and tested against Minecraft 1.7.10, Forge 10.13.4.1614, and HQM 4.4.4.

Portal Data Preservation

Quest gates keep their configured state while moving:

• NBT Capture: Captures TileEntityPortal data before the piston replaces the source block.
• Moving Piston Storage: Stores the captured portal data on the temporary moving piston tile entity.
• Restore Queue: Restores the portal snapshot after movement finishes.
• Quest Binding: Keeps the assigned quest.
• Portal Settings: Preserves portal type, custom display item, collision flags, texture flags, and player data.
• Save Safety: Persists custom moving-piston data through NBT if the world is saved mid-movement.
