I am currently trying to make an AI driven Semi Truck with a trailer attached permanently. I am needing to make a semi for a traffic simulation. Any help will be appreciated.
I dont know exactly how you can make the wheels part, but the cart part you can use constraints to “fix” the trailer to the car, as for the wheels in the trailer unreal probably has some class to handle that but i am not sure.
Constraints work well, as a constraint, were you fix 2 things together or make something move only in an axis, you get the idea.
Try making a cube that drags behind a car, after that just add the wheels, there should be some simple tutorials on youtube.
