Adam's towing and more is a mod that provides the ability to tow vehicles together. The base mod provides a modified Ural and a lowboy trailer that can be used together. The intention is mostly to act as a common system that can be used for other modders to create new content.

How to use

User:

• Subscribe to workshop and load mod
• Look for the "Lowboy" and "Ural" (with the modified hitch on the back)

Developer:

• Set this mod as a dependency
• Use the components ADM_TowChild and ADM_TowParent
• ADM_TowParent
  • Receiver Type: List of common hitch receivers that exist in real life, feel free to mod the enum to add custom ones.
  • Joint Position: PointInfo that defines the location that the joint will attach to in local space of the entity it is applied to.
  • Max Attach Distance: Maximum distance a child receiver can be from the parent receiver.
  • Tow Signals: Signals to modify when tow state is updated. (e.g. jack stands or dolly)
    • Signal: Name of signal
    • Detached Value: Value when child is detached
    • Attached Value: Value when child is attached.
• ADM_TowChild
  • Receiver Type: List of common hitch receivers that exist in real life, feel free to mod the enum to add custom ones.
  • Joint Position: PointInfo that defines the location that the joint will attach to in local space of the entity it is applied to.
  • Joint Break Force: How much impulse is required to break the joint. (I assume this is in Newtons * seconds, unsure though)
  • Child Brake Percent: What percentage of parent vehicle brake should be applied to the child vehicle. (If 80% brake is applied to parent and this is set to 20%, the resulting braking on the child is 0.8 * 0.2 = 0.16, or 16%) 
  • Track Steering: Should child vehicle steer towards the parent vehicle
  • Track Steering Strength: Scalar value that affects how much angle to steer towards parent vehicle.
    • Dot product result is scaled by this. I didn't bother calculating true angle since it will change per vehicle, probably easier to just scale dot product.
  • Synced Signals: Synced from parent to child vehicle. 
    • Parent Signal: Name of signal on parent to reference a value
    • Child Signal: Name of signal on child to apply reference value to
    • Signal Scale: Multiplier on reference value
    • Signal Offset: Offset reference value by some amount
  • Tow Signals: Signals to modify when tow state is updated. (e.g. jack stands or dolly)
    • Signal: Name of signal
    • Detached Value: Value when child is detached
    • Attached Value: Value when child is attached.
