Landtrain/README.md

Landtrain

Landtrain extends Towbars to support chained towing.

Important

Project Zomboid base BaseVehicle.addPointConstraint() force-breaks existing constraints. To keep 1 -> 2 while attaching 2 -> 3, Landtrain includes a Java class override:

• zombie/vehicles/BaseVehicle.class

This is the same override pattern used by mods like Realistic Car Physics (manual zombie folder copy).

Apply patch to game

1. Run:

.\tools\patch-game-basevehicle.ps1

2. Ensure both mods are enabled:
   • hrsys_towbars
   • hrsys_landtrain

Restore vanilla class

.\tools\restore-game-basevehicle.ps1
