Aeronautics Display Link Fix [ADLF]

航空学显示链接器修复 [ADLF]

English

Overview

Fixes a bug in Create: Aeronautics where the Display Link's TargetOffset gets corrupted during physics assembly/disassembly when both the Display Link and its target sign are on the same contraption.

Applicable Scenario (Case 3)

Case	Description	Before Fix	After Fix
Case 1	Sign on ground, DL on airship only	✅ OK	✅ OK
Case 2	Sign on a different contraption	✅ OK	✅ OK
Case 3	Sign and DL on the same contraption	❌ TargetOffset corrupted	✅ Rotation-aware correction

How It Works

A Mixin injects into Sable's SubLevelAssemblyHelper.moveBlocks() method:

Phase 1 (before loadWithComponents): Detects whether the DisplayLink's target sign is in the same assembly (Case 3). If so, saves the original DL position and relative offset.
Phase 2 (moveBlocks TAIL): Uses Sable's transform.apply() to independently compute the correct new target position, then calculates correctedOffset = newTarget - newDLPos. Writes back only if the current value is incorrect.

A two-layer detection covers both forward (blocks→physics) and reverse (physics→blocks) assembly directions, while correctly excluding normal Case 1/2 scenarios.

v1.2 New Features

Rotation-aware offset correction: v1.2 now properly calculates the TargetOffset after rotation, supporting Aeronautics' internal rotated assembly calls
Configuration file: adlf-common.toml provides a debug = false/true toggle; switch without restart to enable detailed tracing
Optimized logging: Silent in production by default (errors only); enable debug for full Case 3 detection and fix tracing

简介

修复 Create: Aeronautics（机械动力航空学）中当显示链接器（Display Link）与告示牌同处一架飞行器时，物理化/反物理化后 TargetOffset 异常导致无法正常显示的问题。

适用场景（Case 3）

场景	说明	修复前	修复后
Case 1	告示牌在地面，只在飞行器上放置 DL	✅ 正常	✅ 正常
Case 2	告示牌在另一飞行器上	✅ 正常	✅ 正常
Case 3	告示牌和 DL 在同一架飞行器上	❌ TargetOffset 被错误变换	✅ 正确的旋转感知偏移

实现原理

本 Mod 通过 Mixin 注入 Sable 的 SubLevelAssemblyHelper.moveBlocks() 方法：

Phase 1（loadWithComponents 之前）：检测 DisplayLink 的 TargetOffset 是否为相邻方块的相对偏移（绝对值 < 1000），若目标方块也在同一组装中（Case 3），则保存原始 DL 坐标和偏移
Phase 2（moveBlocks TAIL）：用 Sable 的 transform.apply() 独立计算旧目标方块的正确新位置，然后算出 correctedOffset = newTarget - newDLPos，仅在当前值不正确时写入

双层判定逻辑覆盖正向（方块→物理化）和反向（物理化→方块）两个组装方向，同时避免误判正常的 Case 1/2 场景。

v1.2 新功能

旋转感知偏移修正：v1.2 现在会正确计算旋转后的 TargetOffset，支持 Aeronautics 内部的转角组装调用
配置文件：adlf-common.toml 提供 debug = false/true 开关，无需重启即可切换详细日志
日志优化：生产环境下默认静默（仅报错日志），开启 debug 后输出完整的 Case 3 检测和修复追踪信息
