I took your advice and made this setup and it works perfectly. I just have to play with the angular limits and other settings to get it to “turn and follow” like a regular trailer
For the other guy trying to make a trailer… I took the gun_carriage BP and reparented its parent class carriage to be pawn instead of actor so that it could be possed and added a camera above the back coupler then just did the above BP, posseed the first gun_Carriage exactly like in the stock level bp and pulled on them with the manipulators. Its touchy but I think once I start playing around with trailers built off your design and using the physics constraint spawned when I want to “hitch” a ttrailer and using a regular wheeledVehicle class for the pulling vehicle I’ll be in business.
Much thanks! Your project has spawned hope in a pet project that goes back since 2013! Particularilly the gearbox and engine setup. I dunno why I never thought to use curves for an engine torque curve for example. Having to rely on the stock wheeledvehicle class which we all know sucks ATM for doing any sort of “pulling” or wheel turning has always caused my ideas to fail. Your vehicles are so rock solid I should be able to use them for inspiration. I’m not making tracked vehicles (well maybe a few later) so that makes it much easier. Thank you
