*What are you attempting to achieve?
I want to stop the train from shaking while keeping most of the train’s main frame aligned with the tracks.
- What is the issue? (Keep it simple and clear - Include screenshots/videos/GIFs if possible)
The train either vibrates and shakes, or it is misaligned and wobbles. I have been able to solve one or the other issue but not both. For example, I stopped the train from shaking on curves by removing two circular gliders (see below) on the back bogey, but the train would not stay aligned and wobble as well. When I put the two gliders back on the back bogey, the wobble and misalignment stops, but the train vibrates and shakes on curves pretty badly.
Here are some photos and a clip to give a better idea of what is going on. If you need a copy of the game to solve the question, feel free to private message me, I just don’t want to put it out in public yet.
The image below shows what a bogey looks like, back and front are same. The four yellow spheres are the gliders. As previously mentioned, I removed two of them for the back bogey to solve the shaking, but instead causes misalignment and wobbling after straightening from a curve. Yellow cylinders are “wheels” which slide along the rails. Green cylinder bar keeps the bogies from derailing upwards.
Here is an image of the cross section with the main frame of the train lifted up. The gray blocks of the bogies connect to the floor of the train (that red carpet at the top) by a HingeConstraint, as seen by the red lines. This allows the bogies to pivot. Without pivoting, the bogies get stuck and the train gets stuck as well on turns. The fake “bogies” that are black and the black boxes are not collide-able, cannot touch, and cannot query, the bogies go right through them when I attach the Main Frame to the Bogies. The green constraint line is a WeldConstraint which connects the coupler to the floor of each carriage, in this case Carriage1 and Carriage2. The coupler has a RodConstraint which is 1.4 long. You can kinda see the coupler behind the ScreenGUI on the bottom right.
This video below shows the vibration and shaking when all four gliders are present in the back.
- What solutions have you tried so far? (Have you searched for solutions through the Roblox Wiki yet?)
I have tried A LOT of things. Removing gliders on bogies, changing the positions of the gliders on the bogies, adding a center bogey, and even trying to align the first carriage and stop the wobbling from the coupler, while removing two of the gliders causing the shaking. Been stuck on this for a full week so any help would be extremely appreciated.
